HOW THE INTERNET WORKS
• When information is passed from one computer system to another it is
broken up into pieces using TCP protocol.
• Using the IP protocol, a message consisting of not more than 1500bytes or
characters is put into a packet. Each packet has the address of the sender
and receiver and the destination. These addresses are called IP addresses.
• The packets are passed from one network to another until they reach their
destination. At the desesintion the TCP software reassembles the packets
into a complete message.
• If the packets are lost or damaged , a request is sent to resend them.
INTERNET PROTOCOL
• The Internet Protocol (IP) is the method or protocol by which data is sent
from one computer to another on the Internet. Each computer (known as a
host) on the Internet has at least one IP address that uniquely identifies it
from all other computers on the Internet.
