Glossary of Technical Terms

You don't speak geek? Here is an explanation of technical terms. Please click on a selection below:


  1. Ajax

    Ajax (Asynchronous JavaScript and XML) is a method of building interactive applications for the Web that process user requests immediately. Ajax allows content on Web pages to update immediately when a user performs an action, unlike an HTTP request where users must wait for a whole new page to load.

  2. Address (A) Record

    An A-record is an entry in your DNS table (zone file) that maps a website address ( to an IP address. The A-record specifies the IP address to which the user would be sent for each domain name.

  3. Alias(es)

    An email alias is not a real email account. Instead, it's an address that forwards all email it receives to another email account.

  4. Backbone

    A backbone is the network of connections and high-speed lines that carries Internet traffic. The less network distance between your provider and the backbone, the faster and more reliable your website will be.

  5. Bandwidth

    Bandwidth is the total amount of data that can be sent through a network connection at a certain time, usually measured in bits per second (bps), megabits per second (Mbps), or gigabits per second (Gbps).

  6. Bit

    A Bit (Binary Digit) is a single digit number in base-2, in other words, either a 1 or 0. It is the smallest unit of computerised data. Bandwidth is usually measured in bits-per-second.

  7. Bcc

    A Bcc (blind carbon copy) is a copy of an email message sent to a recipient whose email address does not appear in the message.

    This is in contrast to To and Cc recipients, whose addresses do appear in the respective header lines. Every recipient of the message can see all the To and Cc recipients, but does not know about Bcc recipients.

  8. Browser

    A browser is client software that is used to locate and display web pages. Examples include Microsoft's Internet Explorer and Netscape's Navigator.

  9. Byte

    A Byte is a set of bits that represent a single character. Usually there are 8 bits in a byte, sometimes more, depending on how the measurement is being made.

  10. C, C++

    C is a structured, procedural programming language that has been widely used both for operating systems and applications and that has had a wide following in the academic community. Many versions of Unix-based operating systems are written in C.

    With the increasing popularity of object-oriented programming, C is being rapidly replaced as the programming language by C++, a superset of the C language that uses an entirely different set of programming concepts.

  11. Captcha

    In a captcha test (Completely Automated Public Turing test to tell Computers and Humans Apart), an image of letters is dynamically generated. The letters, because they're part of an image and not text (e.g. text that you could cut and paste), are difficult for a spambot or other computer program to read. However, a person has little trouble reading the letters in a captcha image.

    Using a captcha test on a website is a great way to ensure, for instance, that a person and not a spambot is filling out a web form. Also, a captcha can make it difficult for a person to continuously resubmit form information and overwhelm the form's purpose.

  12. Catch-all Email Account

    A catch-all email account collects all messages addressed to non-existent or misspelled usernames at the domain, as long as the domain name is correct.

  13. Certificate Authority

    A Certificate Authority is an issuer of security certificates that is used to establish credentials and verify identities when performing electronic transactions.

  14. CGIMAIL (form-to-script)

    CGIEMAIL is a flexible, configurable script to enable the submission of an HTML form result by email.

  15. CGI script

    Common Gateway Interface (CGI) is a standard method of transmitting information between an application and a web server. CGI scripts are used to supplement basic HTML pages by making your website more interactive and functional.

    You can program many useful features in CGI scripts, such as hit counters, guest books, order forms and message boards.

  16. Chilisoft

    Chilisoft is a powerful tool for deploying Active Server Pages (ASP) under a UNIX/Linux environment.

    ParkHost supports ASP up to version 3. For more information and reference manual on Chili!Soft please browse to

  17. Cname (canonical name)

    A Cname is a record in a DNS database that indicates the true host name of a computer that its aliases are associated with. In other words, the Cname record specifies another domain to which the user would be redirected.

  18. Cookie

    A cookie is a preference file written to the user's computer when they access a website.

    Cookies are commonly used to store account information that can be used when the website is revisited at a later date. For example, if the layout or content of a website can be customised, a cookie could be used to 'remember' the user's preferred background colour or news source. Only the website that created the cookie file can use the information it stores.

  19. Cron

    A cron is a UNIX command used to schedule jobs to be executed at some time in the future, typically on a periodic or regular basis. When used as a daemon process, the cron runs continuously and executes in response to specified events.

  20. CSR

    Before ordering an SSL certificate, it is necessary to first generate a CSR (Certificate Signing Request) on the server on which your domain resides. A CSR is not a piece of software, but rather just a body of text. Your CSR will contain encoded information specific to your company and domain name; this information is known as a Distinguished Name or DN.

    In the DN for most servers are the following fields: Country Name, State or Province Name, Locality Name, Organisation Name, Organisational Unit Name, and Common Name.

    Should you wish to acquire a certificate independently, ParkHost can generate and provide you with the CSR.


  1. Database

    A website database is a program that can store information in related "pieces" such as names, products or prices, and then can present it as you wish. At ParkHost we provide MySQL, a popular open source database.

  2. Data Centre

    A Data Centre is a secure location for Web hosting servers that is specially designed to provide physical and network security for servers and the data stored on them.

  3. Data Transfer per month

    Also known as your Traffic. Each time visitors access a webpage, image, audio, video or other element on your site, traffic is generated. Your aggregate traffic is the sum of all outward-bound, inward-bound, email and FTP traffic.

  4. Disk space

    Disk space is the amount of allocated storage you are given on your Web hosting account. This enables you to store files, web pages, email, databases and graphics. Disk space is measured in MB (megabytes).

  5. DNS

    DNS (Domain Naming System) is the system responsible for translating domain names into numeric IP addresses. The DNS maintains a list of all the domain names and distributes them throughout the world.

  6. Domain Name

    A domain name is the unique label that identifies a specific website, such as Typically, domain names convey information about a site and are easier to remember that the associated numeric IP address. When a user types a domain name in a browser, the DNS locates the registered domain name and translates that into a numeric IP address.

  7. Down-time

    The amount of time your website is disconnected or inaccessible via the Internet is known as down-time.

  8. E-commerce

    E-commerce (electronic commerce) refers to the general exchange of goods and services via the Internet. This method of business is seen as a viable alternative to export driven economies to overcome geographical distance.

  9. Email Addresses

    This refers to an electronic mailing address to which email may be sent and received. Email is short for electronic mail. It consists of messages, often just text, sent from one user to another via a network.

  10. Email Attachments

    Attachments are separate files that are sent or received along with your email messages. An attachment can be anything from word processing documents to digital photos, from spreadsheets to web pages.

  11. Email Auto Responders

    Auto responders may be used to send automated responses to incoming e-mail sent to a specific address. An auto responder could be used to send a standard message.

  12. Email Forwarding

    Email forwarding enables you to have email messages sent to one address automatically forwarded to a different email address.

  13. Favicon

    A favicon, or Favourites Icon, is a small graphic that is associated with a page or website. When a user bookmarks a specific web page, that web page loads a customised icon into the user's browser, typically a tiny version of a company or website's logo. The favicon is displayed next to the website's name in the Favourites list and can also be displayed in the Links toolbar. When a site has not created a favicon, your Web browser will load its own logo into the browser by default.

    When a user bookmarks a page, the browser will request a favicon.ico file from the directory of the web page. If such file exists, the web page is using a favicon and will return the file to the browser.

  14. Firewall

    A firewall is a hardware and software combination buffer between an internal network and the internet. A firewall allows only specific kinds of messages from the Internet to flow in and out of the internal network. This protects the internal network from intruders and/or prevents hackers from breaking into the systems.

  15. Form to email

    FormMail allows you to use a form to receive email from your users. FormMail is typically set up by means of an HTML FORM tag that defines the fields and a CGI script that handles input validation, error control and other actions.

  16. FrontPage Extensions

    FrontPage Extensions, a CGI program, provide the server side implementation of FrontPage. Common features in FrontPage requiring extensions are counters, forms, search functions, guest books and post forums.

    ParkHost no longer offers FrontPage Extensions as part of our list of supported services.

  17. FTP

    FTP (File Transfer Protocol) is a method used to transfer files across the Internet. FTP is typically used to upload and download files between your own computer and the web server hosting your site. FTP requires a valid username and password.

  18. Fax-to-Mail

    Fax-to-Mail enables users to receive faxes directly to an email inbox.

  19. Flash

    Flash files are media files that are processed client side. When a user browses to a flash file on your website they require a flash player to be installed on their computer locally. Keeping the size of flash files down is important for responsive websites.


  1. GCC

    The GNU Compiler Collection (usually shortened to GCC) is a set of programming language compilers of the GNU environment (GNU is a UNIX-compatible operating system). The GCC now contains compilers for the C, C++, Objective C, Fortran, Java and Ada programming languages.

    A compiler is a program that converts the source code versions of other programs into assembly language or machine language, which can be read directly by a processor. The GCC is designed to support multiple front-ends and back-ends by translating first into Register Transfer Language and from there into assembly code for the target achitecture.

    GCC is available, on request, with ParkHost's Basic Web hosting package and higher.

  2. Gigabyte

    A gigabyte is 1024 megabytes.

  3. Greylisting

    The term "Greylisting" is meant to describe a general method of blocking spam based on the behavior of the sending server, rather than the content of the messages.

    When mail is received from a foreign host for the first time, the mail is temporarily rejected. If it is a valid mail server, it will retry the delivery after a predetermined time. On the second delivery attempt of the sending server the mail server will accept the email and whitelist the domain for future mail deliveries.

    Spam servers do not retry delivery of a mail that was rejected.

  4. Hit

    As used in reference to the Internet, "hit" means a single request from a web browser for a single item from a web server; thus in order for a web browser to display a page that contains 3 graphics, 4 "hits" would occur at the server: 1 for the HTML page, and one for each of the 3 graphics.

    Keeping track of hits is a way of measuring traffic to a website. The number of hits a site receives is usually much greater than the number of actual visitors. That is because a webpage can contain more than one item.

  5. Hosting

    The term "hosting" can be used to refer to the housing of a web site, email or a domain.

  6. .htaccess

    .htaccess is the default name of a configuration file that contains server directives (small commands known by the server) that tell the server how to behave. An .htaccess file is used to restrict access (password-protection) to specific files and/or directories on the Internet or an intranet.

  7. HTML

    HTML (HyperText Markup Language) is a programming language used to build websites; it defines how the webpages will look and how the visitor will be able to move around the website.

  8. HTTP

    HTTP (Hypertext transfer protocol) is a protocol used to request and transmit files, especially web pages and webpage components, over the Internet or other computer networks. The protocol for moving hypertext files across the internet requires a HTTP client program on one end, and an HTTP server program on the other end.

  9. Hypertext

    Hypertext is, generally, any text that contains links to other documents - words or phrases in the document that can be chosen by a reader and which cause another document to be retrieved and displayed.

  10. ICANN

    The Internet Corporation for Assigned Names and Numbers (ICANN) is responsible for managing and coordination the Domain Name System (DNS) to ensure that every address is unique and that all users of the Internet can find all valid addresses. It does this by overseeing the distribution of unique IP addresses and domain names. It also ensures that each domain name maps to the correct IP address. ICANN is responsible for accrediting the domain name registrars.

  11. IMAP

    IMAP (Internet Message Access Protocol) is a client/server protocol in which e-mail is received and held for you by your Internet server.

  12. IP Address

    An IP address is a unique, numeric identifier used to specify hosts and networks. Internet Protocol (IP) numbers are part of a global standardised scheme for identifying machines that are connected to the Internet.

    Technically speaking, IP numbers are 32 bit addresses that consist of four octets, and they are expressed as four numbers between 0 and 255, separated by periods, for example: .

  13. ISP

    An ISP (Internet Service Provider) is a company that provides access to the Internet in some form.

  14. httpd.conf

    The httpd.conf file is an Apache configuration file in text format. Although the file is not accessible to clients, many httpd.conf directives can be implimented with a .htaccess file to override the default settings.

  15. IonCube

    The IonCube PHP Accelerator is an easily installed PHP Zend engine extension that provides a PHP cache. It is also capable of delivering a substantial acceleration of PHP scripts without requiring any script changes, loss of dynamic content, or other application compromises.

    Ioncube PHP works much the same as Zend Optimizer, however Ioncube can be installed without making any changes to the server, and is therefore suitable for Managed shared and dedicated clients.

    IonCube can be installed by downloading it from the IonCube website. Just extract and upload the files into your public_html folder.

  16. Horde

    Horde is the supplier of PHP-based email software used for customers to access webmail.


  1. Java

    Java is an object-oriented programming language invented by Sun Microsystems that is specifically designed for writing programs that can be safely downloaded to your computer through the Internet and immediately run without fear of viruses or other harm to your computer or files.

    Using small Java programs (called "Applets"), Web pages can include functions such as animations, calculators, and other fancy tricks.

  2. Kilobyte

    A kilobyte is a thousand bytes. Actually, usually 1024 bytes.

  3. LARA

    The LARA is a remote access console that can be connected to Co-located and TruServ Dedicated servers. It provides server administrator with a means of administering a non responsive machine. The server administrator is able to access the LARA interface from a web browser and, by using a randomly assigned username and password, make any configuration modifications that are required in order to restore the server to its former functionality.

    The LARA is a free service for all Co-located and TruServ Dedicated server customers. To have the LARA connected to your server in one of our data centres, an email request from an authoritative contact to the support team is required. Kindly note that while the LARA has to be specially configured on a per session and per client basis, average response times will vary depending on the availability of the LARA console and ParkHost technical staff.

  4. Linux

    Linux is a free Unix-type operating system initially developed by Linus Torvalds that runs on a variety of hardware platforms. The source code for Linux is freely available to everyone. Its reliability and cost has made it a popular choice as the basis for computer networks and is commonly used as the operating basis for Internet servers.


  1. Mail Client

    A Mail client is an application that runs on a personal computer or workstation and enables you to send, receive and organise email. It's called a client because email systems are based on client-server architecture. Mail is sent from many clients to a central server, which re-routes the mail to its intended destination.

  2. Mail Exchange (MX) record

    An MX record indicates which mail server will receive emails for a domain. Each domain can have more than one MX record, allowing email to be routed to a backup mail server should the primary be unavailable.

  3. Megabyte

    A megabyte is a million bytes or a thousand kilobytes.

  4. Mod_gzip

    Mod_gzip is a module for the Apache web server that compresses eligible web pages on the fly before sending them to compatible browsers. The compressed data that is generated reduces the number of bytes transferred to the web browser, without any loss in the structure or content of the original, uncompressed document.

    This can both speed up the loading of a web page, especially for browsers on a slow connection, and save significantly on bandwidth usage.

    Mod_gzip content acceleration is enabled by default on all ParkHost hosting accounts.

  5. Mod_perl

    Mod_perl is an Apache module that embeds a Perl interpreter into the Apache web server so that users are able to create dynamic content using the Perl programming language. It is installed by default on all Webhosting accounts and Managed Dedicated servers.

  6. Mod_rewrite

    Dynamic websites that use scripting languages such as ASP or PHP often generate complex URLs (Uniform Resource Locator) that are difficult to remember and not search engine friendly. The Apache module "mod_rewrite" allows you to change the URLs displayed by your website in a web browser. These "mod_rewrite" rules must be specified with an .htaccess file in the root folder of your web content.

  7. MySQL

    MySQL is an open source RDMS (Relational Database Management System) that makes use of SQL (Structured Query Language) for processing data. It is a very popular application for websites that require a database back-end.

  8. Nameservers

    A nameserver is a computer that performs the mapping of easily remembered domain names to IP addresses. It is also sometimes referred to as a host server.

  9. Network

    A network is a collection of terminals, computers, servers, and components which allows for the easy flow of data and use of resources between one another.

    Any time you connect two or more computers together so that they can share resources, you have a computer network.

  10. MIME

    MIME - (Multipurpose Internet Mail Extensions) refers to the standard in which email is sent via the internet. MIME messages can contain text, images, audio, video and other application specific data.

  11. open_basedir

    Open_basedir is a function within PHP which defines access to files via specific locations or paths. Files located outside of the path will be refused.


  1. Parked Domain

    A Parked domain refers to a domain name that points to the same website as the domain name on which it is "parked". For example, you can park "" on the domain name "". If someone types the parked domain name "" into a web browser, it will point to the same website that "" points to.

    The web browser's address bar will display the parked domain name and will not display the domain name on which it is parked. A Parked domain name has the same IP address as the domain name on which it is parked.

  2. PHP

    PHP is a powerful, server-side scripting language that allows developers to create dynamic content that interacts with databases. PHP is especially suited for Web development and can be embedded into HTML pages.

  3. php.ini

    php.ini is the PHP configuration file in which PHP directives are recorded. These can be altered by updating the php.ini, please contact us for more information, if you would like to change the php.ini file. A .htaccess file would take preference over a php.ini file. ParkHost discourages the use of .htaccess for the configuration of PHP directives as .htaccess files are not directly compatible with our servers. We have put measures in place to facilitate their use, however it is not recommend

  4. Ping

    Ping is a basic Internet program that lets you verify that a particular IP address exists and can accept requests. The verb ping means the act of using the ping utility or command. Ping is used diagnostically to ensure that a host computer you are trying to reach is actually operating.

  5. POP

    POP (Post Office Protocol also known as Point of Presence) is an extensible protocol for retrieving mail from a remote server. Periodically, you (or your client email receiver) check your mailbox on the server and download any mail.

    A Point of Presence usually means a city or location where a network can be connected to, often with dial up phone lines.

  6. PostgreSQL

    PostgreSQL is an object-relational database management system that has the features of traditional commercial database systems with enhancements to be found in next-generation DBMS systems.

    ParkHost no longer offers PostgresSQL as part of our list of supported services.

  7. Propagation

    When a visitor types your domain name into their Web browser, their request is referred to a nameserver that indicates the physical location (the IP address) of your domain on the Internet. When your site location changes to a new IP address, or when a new domain name is added, nameservers around the world must be notified of the change. This process is referred to as propagation.

    Propagation normally requires 24 - 72 hours.

  8. Really Simple Syndication (RSS)

    RSS is a method of syndicating or publishing information on your website through an XML application. This allows other websites or applications to import your RSS feed, which contains the information you are publishing, into their website or application.

    RSS is used to publish frequently updated digital content, such as blogs and news feeds.

  9. Registrant

    A Registrant is the person or organisation registering a domain name, the registrant is also the recorded owner of a domain name.

  10. Registrar

    A Registrar is a company that has been certified to register domain names. The organisation ICANN is responsible for certifying companies as domain name registrars.

  11. Renewal (domain name)

    Most TLDs need to be renewed at some scheduled yearly interval. This is an opportunity for both the registrant and the registry to update their records as well as collect any applicable renewal fees.

  12. Robots.txt

    By placing the robots.txt file in the public_html directory of a domain, the user is able to specify what search engines are allowed to do indexing of the site. This is a useful tool to block search engines that cause excessive traffic volumes on a particular domain.

  13. Root directory

    In a computer file system that is organised as a hierarchy or tree, the root directory is the directory that includes all other directories and files.

  14. PTR

    Pointer Records refer to DNS reverse mapping. This allows DNS administrators to link a hostname to a specific IP address and enables users to identify who an IP belongs to. It is also used for security purposes in mailling systems. Custom PTR records can be created for ParkHost clients using the ParkHost IP range. This service is available to dedicated-, root- and co-located server clients.

  15. Ruby on Rails

    Ruby on Rails (RoR) is a web application framework that offers developers the ability to create database driven websites using it's code framework. ParkHost's standard hosting platform does not support the minimum requirements for Ruby on Rails.

    More information on Ruby on Rails can be found at

  16. Python

    Python is a popular programming language that allows for efficient handling of code through minimal syntax and ease of readability. Python is supported with the Basic account and higher. This dynamic and easy to learn language uses a file extension of .py; version 2.4 is supported on our standard Debian operating system.

  17. PEAR

    PEAR is the acronym for PHP Extension and Application Repository. It is a repository for PHP code; providing a structured diffusion system for PHP components that can be reused.


  1. Script

    A script is a programme or sequence of instructions that is interpreted or carried out by another programme rather than by the computer processor.

  2. Search Engine

    A Search Engine is a tool allowing users to search for information on the Internet using key words and phrases. Search engines explore the Internet and return a list of web pages that are related to the key words or phrases entered. Search engines are also a tool to market your website to potential visitors.

  3. Server Side Includes (SSI)

    SSI is an HTML command used to place up-to-date data into a web page before sending it to the user. For example, it can be used to retrieve the current date and size of downloadable files that are constantly changing. HTML pages that contain server side includes often use the .shtml file extension.

  4. Shared SSL

    Secure Socket Layer (SSL) is a protocol that provides encrypted communications on the Internet. This is used primarily for financial transactions that take place over the Internet.

  5. .shtml

    .shtml is a web file suffix - for example, index.shtml. .shtml files are files which can include server generated content on the page, like a counter. A typical use is to include a 'Last modified' date at the bottom of the page.

    .shtml files are setup on a web server as server side include (SSI) files. Other files can be setup as server side include, but .shtml files are common on linux hosts.

  6. SMTP

    Simple Mail Transport Protocol (SMTP) is a protocol used in sending and receiving e-mail. However, since it is limited in its ability to queue messages at the receiving end, it is usually used with one of two other protocols, POP3 or IMAP, which let the user save messages in a server mailbox and download them periodically from the server. In other words, users typically use a program that uses SMTP for sending e-mail and either POP3 or IMAP for receiving e-mail.

  7. Spam Filter

    Spam is the term for unsolicited mass email. Spam filters attempt to identify spam email and prevent it from being delivered to your inbox.

  8. Spooling

    Acronym for simultaneous peripheral operations on-line, spooling refers to putting jobs in a buffer, a special area in memory or on a disk where a device can access them when it is ready. Spooling is useful because devices access data at different rates. The buffer provides a waiting station where data can rest while the slower device catches up.

    The most common spooling application is print spooling. In print spooling, documents are loaded into a buffer (usually an area on a disk), and then the printer pulls them off the buffer at its own rate. Because the documents are in a buffer where they can be accessed by the printer, you can perform other operations on the computer while the printing takes place in the background. Spooling also lets you place a number of print jobs in a queue instead of waiting for each one to finish before specifying the next one.

  9. SSH

    SSH (Secure Shell) is a protocol, which works much the same way as Telnet, for creating a secure connection between two computers. The secure SSH connection provides authentication and encryption to ensure that your password and all data sent and received during your session are kept safe.

  10. SSL

    SSL (Secure Sockets Layer) is a method of ensuring that information submitted through your website is secure and cannot be accessed by unauthorised users. Information submitted via an SSL-secured form is transmitted in an encrypted state. SSL is most commonly used for online credit card transactions.

  11. SSL Certificate

    A SSL (Secure Sockets Layer) Certificate is an electronic document that contains the information necessary to establish a secure SSL connection. When SSL is used in credit card transactions, the website collecting the credit card information and the site to which the information is being transmitted must both have an SSL Certificate.

    A digital certificate proves your company's or server's identity online and by doing this, creates a sense of trust and confidence in using your website.

  12. Streaming

    Streaming is a technique for transferring data in a continuous flow to allow large multimedia files to be viewed before the entire file has been downloaded to a client's computer.

    RealAudio, RealVideo and QuickTime movies are examples of streaming media.

    Audio and video streaming is not offered by ParkHost.

  13. Sun Java System ASP

    Sun Java System ASP is a licensed Web server plug-in which provides full ASP (Active Server Pages) support for a variety of Web servers (for example Apache and Java System Web Server 6) running on a number of operating systems (for example Linux, Sun Solaris and Win NT / 2000).

    Sun Java System ASP supports the following Microsoft standards: ASP 3.0, MS VBScript 5.5, MS Jscript 5.5 and MS ADO 2.0. As a result of this standard compliance, ASP pages can be ported to Sun Java System ASP with little or no changes.

  14. Telnet

    Telnet is a terminal emulation protocol that lets a user log in remotely to other computers on the Internet; it has a command line interface.

  15. Temporary URL

    Your temporary URL is the URL provided to you so that you can upload and test your site while you wait for the domain name registration and transfer period to complete. Your temporary URL is just another way of accessing your site. Once the propagation period completes, no special action is required in order to start using your domain name; all of the website files you uploaded using your temporary URL will still be in place and nothing will have changed.

  16. Tomcat

    Tomcat is a Java Servlet container and web server from the Jakarta project of the Apache software foundation. Tomcat enables the hosting of JSP driven websites. JSP is no longer supported by ParkHost. For more information see the official Tomcat website at

  17. Top-level domain

    Domain names are composed of at least two levels, a top-level domain and a second-level domain. The top-level domain, also referred to as TLD, is the suffix or extension attached to Internet domain names. There are a limited number of predefined TLDs, such as, .com and .org.

  18. Traceroute

    A traceroute is a utility that records the route (the specific gateway computers at each hop) through the Internet between your computer and a specified destination computer. It also calculates and displays the amount of time each hop took. Traceroute is a handy tool both for understanding where problems are in the Internet network and for getting a detailed sense of the Internet itself.

  19. Traffic

    Each time visitors access a webpage, image, audio, video or other element on your site, traffic is generated. Your aggregate traffic is the sum of all outward-bound, inward-bound, email and FTP traffic.

  20. Transfer (Domain Names)
    • The three most frequent types of transfers are:
    • Transferring your domain name registration to ParkHost.
    • Transferring your domain name registration within ParkHost.
    • Transferring your ParkHost registered domain name to another provider's Domain Name Server (DNS).

  21. Upgrade

    An upgrade is an improvement to your existing hosting package. By upgrading your package you usually get new features and functions.

  22. URL

    A URL (Uniform Resource Locator) is the address for a resource or site (usually a directory or file) on the Internet and the convention that web browsers use for locating files and other remote services.

  23. URL Redirect

    The Redirect URL allows you to change the file that appears when a user enters a specific file's web address.


  1. Virtual Domain

    A Virtual domain refers to a domain name such as "". Each Virtual domain can refer to a unique website on a server. The first domain name on a web hosting account must be a Virtual domain.

    The domain name must be registered with a domain name registrar to use it with your hosting account.

  2. Virus

    Viruses are small files that attach to emails or download and infect your computer. They can be harmless (they place a funny picture on your monitor) or dangerous (they can go through your address book and send everyone within your address book the same virus). More dangerous viruses can wipe out your computer and all your information. Some viruses can take over your machine and send spam from your computer. Without your knowledge, you can become a spammer.

  3. Virus Scanning

    ParkHost uses the Clam AV command line scanner to quarantine virus infected mail before it is downloaded by the client. ParkHost recommends the following approach for detecting and preventing viruses from spreading:

    • On personal computers, apply anti-virus software capable of scanning disks, attachments to email, files downloaded from the web, documents generated by word processing and spreadsheet programs.
    • Use anti-virus software at Internet gateways (e.g. ParkHost) or firewalls to scan email attachments and other downloaded files.
    • Perform regular virus scans on machines used for FTP purposes, as viruses can affect your websites, customers and other users on the server.
    • If you make use of any 3rd party software; ensure you have the latest security updates and patches installed.

    Please note: If a you receive a virus warning on your website or detect any unusual activity, please contact us as soon as possible.

    All users remain responsible for protecting their own network. ParkHost's anti-virus protection serves as an effective, duplicate re-enforcement to guard against malicious email viruses.

  4. Website

    A website is a collection of HTML documents or web pages, that are linked together and that exist on the Web at a particular server. Exploring a website usually begins with the homepage, which may lead you to more information about that site.

  5. Web Hosting

    Web hosting is an online storage service for information, images, video, or any content accessible through the Web.

    With ParkHost's Web Hosting packages, numerous websites are housed on and share the resources of one server.

  6. Web Mail

    Web Mail allows you to access your email account from anywhere using a web browser. You should use Web Mail when you cannot access the computer that you have set up with POP access.

  7. Web Page

    A Web page is a document created with HTML (Hypertext Markup Language) that is part of a group of hypertext documents or resources available on the Web. Collectively, these documents and resources form what is known as a website. Web pages can contain hypertext links to other places within the same document, to other documents at the same website, or to documents at other websites. They can also contain fill-in forms, photos, large clickable images, sounds, and videos for downloading.

  8. Website traffic

    The visitors who come to your website are collectively referred to as your website traffic. You may find it helpful to use a page view counter to track how many visitors your site receives.

  9. WHOIS

    WHOIS is a directory of domain name information. When you register a domain name, your postal address, email address and phone number are automatically published in the public WHOIS database. The Internet Corporation for Assigned Names and Numbers (ICANN), the nonprofit body responsible for accrediting domain name registrars, requires that this personal information be accurate and available for anybody to view on the Internet.

  10. World Wide Web (WWW)

    You can think of the Web as a worldwide collection of text and multimedia files and other network services interconnected via a system of hypertext documents. HTTP (Hypertext Transfer Protocol) was created as a means for sharing data internationally, instantly, and inexpensively. With hypertext, a word or phrase can contain a link to other text. To achieve this, CERN developed a programming language called HTML, which allows you to easily link to other pages or network services on the Web.


  1. Zend Optimizer

    Zend Optimizer is a free application that runs the files encoded by the Zend Guard. Zend Optimizer enhances the performance of PHP applications. Generally this is the main use of the Zend Optimizer software.

    Since Zend is not part of the ParkHost default setup, ParkHost can not be held responsible should future server updates/changes affect websites running Zend negatively
