Today I am talking about how internet works .The internet is a global network of computer is computer connected to the internet must have a unique address internet address are in the form of nnn . nnn .nnn .nnn. nnn must be a number from 0 to 255 the address is known as IP address and basically the internet provide from under the sea and the ISP means internet service provider get the internet to us.

If you connect to internet through any internet service provider you are usually assigned temporary IP address for the duration of your dial in season if you connect to internet from local area LAN Local area network your computer might have a permanent IP address or static IP address obtain a temporary on from DHCP dynamic host configuration protocol server in any case if you are connected to the internet your computer has unique IP address. Your computer is connected to the internet essay unique IP address how does it take another computer connect to the internet an example shown to surveyor let's see your IP address is 1.2.3.4 and want to send a message to the computer 5.6.7.8 the message you want to send is hello computer 5.6.7.8 obviously the message must be there or whatever kind of wire connect your computer to the internet .
)
let's say you have dialled into your ISP from home and the message must be transmitted over the phone line therefore the message must be transferred from alphabet text into electronics signals transmitted over the internet .Then translate back into alphabetic text how it is every computer needs want to communicate on the Internet and it is usually built into computer operating system like Windows Linux the protocol used the TCP IP stack like this.
