Abstract
The internet has been around for more than 50 years. With its invention, communication among people all over the world became faster, cheaper and less cumbersome. People no longer need to move from one place to the other to pass on a message. On the contrary, to deliver mail a lot of time and money is consumed.
Delivery of electronic mail takes seconds and minimal amount of money. The sending of messages and information is done in an imaginary world called cyberspace.
Keywords: Internet, cyberspace, and network
T he Internet consists of a group of computer networks interconnected all over the world. It is simply a large network comprising of smaller computer networks “a network of networks”. A network is formed when two or more computers are connected together. An example is an office or school network comprising of interconnected computers.
These computers are able to communicate with each other and share information. Prehistorically, people used cave paintings to communicate messages and store important information. For example, Moses wrote the Ten Commandments on a piece of stone.
F ormal communication began with the mail, followed by the telephone and then the computer.
Cyberspace is the imaginary world used by computers to communicate with each other. For example, two people communicating with each other via a computer do this in the imaginary word. With the Internet, students can learn from home by sending out their assignments to their teachers a nd receiving notes from their teachers using computers. People can also work at home and send their finished work to the office through computers connected to the Internet. In future, all people will be able to work from home and eliminate the need for offices.
How is cyberspace different from a park?
With the assistance of your teacher send an instant message to your friend and see how fast your friend receives the message.
