Apache - A web server program. Apache is one of the world's most popular web server programs, it was built and is maintained by a group of open source programmers and it is widely used because of it's excellent performance and security features.

Bandwidth - The amount of data that can be transferred at a given moment to or from a server. The larger the bandwidth value the higher amount of traffic your site can handle at one time.

CGI - Short for Common Gateway Interface, a script that processes data supplied by the user, such as in a form application.

CGI-BIN - This is the directory on a web server where CGI scripts are stored.

Cookie - A cookie is a text file sent from a web server to a user's somputer. Information is sent back and forth between between the server and the computer in order to exchange data such as registration information, or to prepare custom content for the user.

Dedicated Hosting - This describes a web site which is hosted on its own server. It is more flexible than shared hosting as webmasters have full control of the server, including choice of operating system. Server administration is still taken care of by the hosting provider. It is however significantly more expensive than shared hosting.

Domain Names - Domain names are the words users enter into the address bar of their browser to visit a site. These domain names are attached to a DNS. The DNS (Domain Naming System) is used to translate these domain names into IP addresses. Each web site on the Internet has an IP address behind the name.

Firewall - A firewall is a software application designed to protect web servers. They are typically used to protect web servers from attacks or unauthorized access.

Flash - A popular application designed by Macromedia. Flash is widely used on the Internet as it requires little bandwidth, which makes it friendly to users with low speed connections.

Frontpage - A site design and management application created by Microsoft.

FTP (File Transfer Protocol) - A method to allow users to transfer files too and from webservers.

HTML (HyperText Markup Language) - The language used by web browsers and web servers to communicate.

Commonly this type of service is being replaced with DSL due to the much higher transfer speed attainable with a DSL service.

Load Balancing - This is used to distribute data across 2 or more servers to ensure that a single web server is not overloaded with traffic thereby affecting network performance.

Managed Hosting - A dedicated server that is supplied with a full suite of technical support, setup, maintenance and monitoring services.

NOC (Network Operations Center) - A hosting company's "home base". The NOC is typically where most administrative, technical support, and physical server housing takes place.

OC (Optical Carrier) - Represents the speed of fiber optic networks. OC speeds range between 1 and 48, typically hosting companies use OC3 fiber connections which allows for the transfer of data at a rate up to 155.52 Mbps (Mega Bits Per Second).

Parking - All domain names when newly purchased need to be stored on a server. Most domain registrars will temporarily place the new domain on their servers until the new owner changes the DNS to point to a different site. While the domain is in this temporary location the domain is known to be parked.

Subdomain - Generally known as a "Domain within a Domain", subdomains are web addresses built upon an existing domain name. For example, "subdomain.domain.com" is built upon "domain.com".

TCP (Transmission Control Protocol) - A very important network protocol, TCP allows two hosts to connect to each other can exchange data, TCP also has checks in place that make sure that data is received exactly as it was sent.

TLD (Top Level Domain) - "webhost-advisor.com" is this site's top level domain, with the suffix being ".com". Other suffixes include ".net", ".org" and ".info".

WHOIS - A central database that tracks all domain name registrations.
