We will also try to peep into the future to see how ICT will look like in the next few decades.
A brief history of ICT
The term “computer” comes from the Latin “computus” and “computare”. Both Latin words mean to determine by mathematical means or by numerical methods. The English verb “compute” has the same meaning.
Basically, a computer is a programmable electronic device that performs mathematical calculations and logical operations, especially one that can process, store and retrieve large amounts of information very quickly. Personal computers are also employed for manipulating text or graphics, accessing the Internet, or playing games or media.
The main components of a computer are:
- a Central Processing Unit (CPU),
- a monitor,
- a Keyboard,
- and a mouse.
Originally the first computers were the size of a large room, consuming as much power as several hundred modern personal computers. Later, computers have become smaller and much more powerful.
While many people use the terms Internet and the Web interchangeably, they are in fact not synonymous. The Internet is a huge network that connects millions of computers together worldwide. Computers in this network can communicate with any other computer as long as they are connected to the Internet. The Web or the World Wide Web (WWW), however, is a way of accessing information over the medium of the Internet. It is an information space or a model that is built on top of the Internet where documents and other web resources are identified by URLs (Uniform Resource Locator), informally termed a web address. This space is interlinked by hypertext links, and can be accessed via the Internet.
The future of ICT is promising. The web will develop even more possibilities.
