MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Packets can often be larger than the maximum size, so each packet is also divided into smaller pieces of data called fragments. The network layer is responsible for fragmentation.

Detailed explanation-2: -Transport layer-breaks down the message into small pieces called packets . Each packet is given a packet number and the total number of packets. The recipient uses this information to assemble the packets in the correct order. It also allows the recipient to see if there are any missing packets.

Detailed explanation-3: -A network packet is divided into three parts; the header, payload, and trailer, each containing values that are characteristic of it.

Detailed explanation-4: -Each packet carries pertinent information, such as source, destination and protocol identifiers, which help the packet select the best available route to its destination.

Detailed explanation-5: -In data communications networks, packet segmentation is the process of dividing a data packet into smaller units for transmission over the network. Packet segmentation happens at layer four of the OSI model; the transport layer.
