Web Hosting Glossary

Active Server Page (ASP or ASP.NET)
An Active Server Page (ASP or ASP.Net) is an HTML page that includes one or more scripts (small embedded programs) that are processed on a Microsoft Web server before the page is sent to the user.

Aliased DNS Servers
Aliasing your nameserver allows you to keep your primary hosting provider transparent. By running "whois" queries on your domain name, a client can often detect that you are reselling services. Therefore, many hosting companies provide to resellers the option of aliased nameservers.

Apache
Apache is a Linux / Unix-based Web server that is used to host about half the sites on the Internet. Originally, Apache was a Unix product, but now versions for Windows, OS/2 and other platforms exist. As with most open-source projects, there are numerous add-ons and tailored versions of the server available, which are created using the Apache module API. The name comes from its origins as a series of "patch files."

Applet
A small Java program that can be embedded in an web page. Applets differ from full-fledged Java applications in that they are not allowed to access certain resources on the local computer, such as files and serial devices (modems, printers, etc.), and are prohibited from communicating with most other computers across a network. The current rule is that an applet can only make an Internet connection to the computer from which the applet was sent.

Bandwidth (Data Transfer)
Bandwidth or data transfer is the measure of the traffic generated from your website. It is measured in bytes, kilo bytes (KB), mega bytes (MB) or giga bytes (GB).

Certificate Authority
An issuer of Security Certificates used in SSL connections.

CGI
(Common Gateway Interface) -- A set of rules that describe how a Web Server communicates with another piece of software on the same machine, and how the other piece of software (the 'CGI program') talks to the web server. Any piece of software can be a CGI program if it handles input and output according to the CGI standard.
Usually a CGI program is a small program that takes data from a web server and does something with it, like putting the content of a form into an e-mail message, or turning the data into a database query.

CGI "scripts" are just scripts which use CGI. CGI is often confused with Perl, which is a programming language, while CGI is an interface to the server from a particular program. Perl is an application of CGI, as well as MIVA, Python, PHP3, and other scripting languages.


cgi-bin
The most common name of a directory on a web server in which CGI programs are stored. The 'bin' part of 'cgi-bin' is a shorthand version of 'binary', because once upon a time, most programs were referred to as 'binaries'. In real life, most programs found in cgi-bin directories are text files -- scripts that are executed by binaries located elsewhere on the server. While most programs using CGI are stored in this directory, it is not a requirement for using CGI.

Control Panel
A control panel is a web based tool for administrating the web site. It helps a webmaster to easily access the settings, tools, utilities provided by the web host via a user friendly interface. With the click of a mouse, he can administer the web space, domain names, e-mail accounts, directories, cgi-bin (program script storage area) and all the special features offered, including site statistics and shopping carts.

Co-located hosting
This hosting option gives webmasters complete control over their server. You are responsible for providing the physical hardware and network administration; the hosting company will provide you with the rack space and Internet connection.

Dedicated hosting
This type of hosting allows a webmaster to rent an entire server. This server is not shared with anybody. This is more flexible than shared hosting (see below), as webmasters have full control over the server, including choice of operating system, hardware, etc.

Ecommerce Shopping Cart
Shopping cart is important for any e-commerce websites. Most of the Unix Web Hosting companies provides the shopping cart in their web hosting plan. This enables the business to add their product on the web and the start online shop. Shopping cart enables the web site to create a custom receipt and order page and emails both you and the customer when an order is completed.

Secure Server (SSL)
Securing the data transferred to and from the web server is very important for some business. So, its very import to have the SSL support for the web sites.

Server Side Includes (SSI)
SSI (Server Side Includes) are directives that are placed in HTML pages, and evaluated on the server while the pages are being served. They let you add dynamically generated content to an existing HTML page, without having to serve the entire page via a CGI program, or other dynamic technology. Almost all the web hosting companies provides SSI support in their web hosting package.

PHP
A server-side, cross-platform, HTML embedded scripting language. PHP is supported by Unix hosts.

FTP
File Transfer Protocol or the method used to "upload" your web site files to storage space on our network. Unix Web Hosting supports FTP.

Anonymous FTP
Capability of setting up a public area where anonymous users can upload and download files from your domain FTP site or browser.

Telnet
Telnet is a telecommunications software utility which allows you to access to a server and become a user on a remote computer. Once you access the remote terminal, you can use it for its intended purposes. Telnet is also supported if your web hosting company enables it for your account.
