Definitions of Computer and Internet Terms

The Tech Terms Computer Dictionary

ICT




Stands for “Information and Communication Technologies.” ICT refers to technologies that provide access to information through telecommunications. It is similar to Information Technology (IT), but focuses primarily on communication technologies. This includes the Internet, wireless networks, cell phones, and other communication mediums.

Internet

The Internet is a global wide area networkthat connects computer systems across the world. It includes several high-bandwidth data lines that comprise the Internet “backbone.” These lines are connected to major Internet hubs that distribute data to other locations, such as web servers and ISPs.

WWW




Stands for “World Wide Web.” It is important to know that this is not a synonym for the Internet. The World Wide Web, or just “the Web,” as ordinary people call it, is a subset of the Internet. The Web consists of pages that can be accessed using a Web browser.

CMS

Stands for “Content Management System.” A CMS is a software tool that allows you to create, edit, and publish content. While early CMS software was used to manage documents and local computer files, most CMS systems are now designed exclusively to manage content on the Web.

Email

Email, short for “electronic mail,” is one of the most widely used features of the Internet, along with the web. It allows you to send and receive messages to and from anyone with an email address, anywhere in the world.

VPN

Stands for “Virtual Private Network” (not a successor to the UPN television network). VPN is a network term that most computer users don’t need to know, but at least you can impress your friends by talking about it. A virtual private network is “tunneled” through a wide area network WAN such as the Internet. This means the network does not have to be located in one physical location like a LAN. However, by using encryption and other security measures, a VPN can scramble all the data sent through the wide area network, so the network is “virtually” private.
