FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Packets can be routed on different paths from sender to receiver. Packets are numbered so if they arrive out of order the message can be reassembled.

Detailed explanation-2: -Packet switching and circuit switching If the network changes, due to congestion or faults, routers can use an alternative interfaces to reach a destination. So packets may travel over different routes to reach the same destination.

Detailed explanation-3: -Packets are transmitted over a network from one computer to another. They are routed through a series of interconnected devices, such as routers and switches, before reaching their final destination. When packets arrive at their destination, they are reassembled into the original data.

Detailed explanation-4: -Packets may or may not follow the same route-they are sent along whichever route gives the quickest transmission. Therefore, packets may arrive out of sequence. Packet switching breaks messages up into small pieces known as packets. Each packet is sent separately across the network.

Detailed explanation-5: -Connection-oriented services use the same path to transmit all the packets, and connection-less does not. if a connection oriented application has been designed, it should transmit the packets using the same path.
