4.2 Packet Switching Tech


In the image shown above it is the entire process of packet switching technology the brown part of the diagram is the shared network system also known as the router it collects all the packets that are sent to it

Computer A, B, C and D. The First part of TCP, breaks information into small chunks called data packets and manages the transfer of those packets from computer to computer.

A single document may be broken into several packets, each containing several hundred character, as well as a destination address . The IP defines how a data packet must be formed and to where a router must forward each packet.

Packets travel independently to their destination, sometimes following differentt paths and arriving out of order.

The destination compute reassembles all the packets on the basis of their identification and sequencing info.

IP data-gram, is a routing and delivery are possible because, as previously mentioned, every computer and router connected to the.

Internet is assigned a unique address, called IP address. A client is any computer, such as a user workstation or PC on the network, or any software application.

A server is any computer on the network that makes access to files, printing, communications, and other services available to users of the network.
