Bandwidth: Usually a measurement to indicate the total amount of data processed by your site. This can include page views, downloads, email and uploads. Bandwidth is usually measured in megabytes or gigabytes.

Billing Contact: The person designated to receive invoices in relation to domain name, hosting services and responsible for ensuring payment of those invoices.

CGI BIN: A folder where common gateway interface (CGI) scripts are stored. As some scripts can create security risks, the CGI BIN is kept outside of the main documents (web page) folders. The CGI-BIN gives the webmaster greater control over access to the applications.


Data Transfer: Same as bandwidth.

Dedicated IP Address: In traditional shared hosting, each domain shares the IP address of the server that domain is stored on. A dedicated IP address is a unique set of identifying numbers for a web site.

Disk/Server/HD Space: The amount of space provided by a web host for the storage of web pages, files and email accounts. Usually measured in Megabytes or Gigabytes.

Domain Alias: A domain that points to the same website as another. For instance, you could have domain.com with domain.net as an alias to domain.com - that way, people accessing domain.net would see the same contact as those viewing domain.com.

Domain Name: A name that identifies a web site. Domain Names always have 2 or more components, separated by dots. While site names may share a common component, no two sites on the Internet may have the same primary nameandtail extension.

EPP Code or Authorization Key: A domain authorization code (also referred to as an Auth Code or an EPP Code) provides an extra level of security for the domain name registration. This code is unique to each domain name and is assigned by the registrar at the time of registration.

Domain Name System (DNS): A database that is used to translate domain names into Internet Protocol (IP) numbers.

E-Mail Alias: An email forwarding account that allows your to direct email to an alias to another email account while also allowing you to send email under the alias name.

Name Server: A computer designed to resolve domain names to Internet Protocol (IP) numbers.

Node: Any computer connected to a network

Open Source: Any application code that has been made available to developers to view and modify freely. Examples of Open Source applications are MySQL and PHP

Raw Log Files: A simple text file that contains all the requests made to a site and the origin of that request; every web page, image, script etc. request is recorded, along with the IP address of the person/system that requested it. Each requested element is entered on a single line. Log files are invaluable tools for determining traffic and also for tracking problems and security breaches.

Redundant connections: Indicates that a hosting service has more than one main connection to the Internet, ensuring continued service should any single connection fail.

Registrant: Person or company that registers a specific domain name and holds the rights over that name for the registration period.

UNIX is an operating system. The job of an operating system is to co-ordinate the various components of a computer -- the processor, the memory, disk drives, keyboards,network equipment monitors, etc. to perform tasks in the proper way - it is the master controller.

UNIX was created in the late 1960s, in an effort to provide a secure multiuser, multitasking system for use by programmers. It is the most common operating system for Internet servers and many different flavors and variations of the operating system have been developed over the years.

We run FreeBSD; derived from BSD, the version of UNIX developed at the University of California, Berkeley.
