The Internet is a combination of words inter and networking, that is the Internet or between networking. The Internet is also known as the Net, which is a computer network that connects millions of computers all over the world.
The Internet is like a huge electronic city. Each citizen owns an Internet Address that can exchange information or news.
As its nature is like a space similar to the hemisphere, the Internet is known as cyber space.
When the computer is connected to the Net, it is like a spider in the centre of a huge web. All the spokes of the web can furnish information from other computers.

 Communication Protocol

The Internet is a communication system that uses the physical connection (usually the telephone lines) to connect computers to the computer netwwork. The Internet uses a standard communication procedure to communicate with other computers.
The Internet is also known as a packet switch network because each data that passes through it will be broken into smaller packets. Each packet is sent separately through a series of switches that is called a router. As soon as they reach their destination, the packet is combined into one as its original form. TCP dan IP are two protocols that aim to break the data into packet, to direct them through the Internet, and then combinining them again when they it reach the desired destination.

The types of pathway that are given by the internet provider are as follows:
  • IP (Internet Protocol) Connection
If we want   to connect all our hardware and software or access the Internet, the we have to use the IP (Internet Protocol) address.
