Internet terminology

Apache:: Apache is an open-source HTTP server for modern operating systems. Well known for being a secure, efficient and extensible web server, Apache's HTTP services are in sync with the current HTTP standards. Apache has been the most popular web server on the Internet since April of 1996. According to the August 2002 Netcraft Web Server Survey found that 63% of the web sites on the Internet are using Apache, making it more widely used than all other web servers combined.
Backbone:: The part of a network that connects other networks together; "the backbone is the part of a communication network that carries the heaviest traffic."
Backup:: To copy files to a second medium (a disk or tape) as a precaution in case the first medium fails. One of the cardinal rules in using computers is "Back up your files regularly". Even the most reliable computer is apt to break down eventually. Many professionals recommend that you make two, or even three, backups of all your files. To be especially safe, you should keep one backup in a different location from the others. (Source: http://webopedia.internet.com).
Bandwidth:: The amount of data that can be passed along a communications channel in a given period of time.
Bit:: A fundamental unit of information having just two possible values, as either of the binary digits 0 or 1.

cPanel:: cPanel (control panel) is a graphical website management tool. The software, which is proprietary, runs on most widely used Linux distributions, and FreeBSD. It is designed for use by commercial web hosting services, so the company does not offer a reduced-cost personal use license.
Disk Space:: This refers to the amount of space (usually in megabytes (MB)) available for use for data storage. In the web hosting sense, this would be the amount of space available to store a website on a given server, as well as space available for FTP and POP3 storage.
DNS:: Domain Name System. The Domain Name System is the system that translates Internet domain names into IP numbers. A "DNS Server" is a server that performs this kind of translation.
Domain Name:: The unique name that identifies an Internet website. Domain names always have two or more parts, separated by dots. The part on the left identifies the site, the part on the right is the grouping under which the name is registered, eg rarebreeds.co.nz
Email response:: Reply to incoming e-mail messages automatically. An auto responder could be used to send "more information" to persons who send e-mail to a specific address, such as info@whateveryouwant.com.

Hit:: A hit is the sending of a single file whether an HTML file, an image, an audio file, or other file type. Since a single Web page request can bring with it a number of individual files, the number of hits from a site is a not a good indication of its actual use (number of visitors).

Name Servers:: A computer connected to the Internet and used to resolve domain names to IP addresses, i.e. it looks up domain names in its tables and returns the value of the associated IP address. Most web hosting companies as well as many businesses have one or more machines assigned as name servers.
PHP:: The PHP Hypertext Preprocessor allows web developers to create dynamic content that interacts with databases. PHP applications are normally found on Linux servers and in conjunction with MySQL databases.
POP3:: POP3 (Post Office Protocol 3) is the most recent version of a standard protocol for receiving e-mail.

Web Hosting:: The World Wide Web is a massive collection of web sites, all hosted on computers (called web servers) all over the world.
