The Maximum size of the data that a frame can carry (at the data link layer) is 1500 Bytes.
Any size data (<65535Bytes) can receive by the network layer from the transport layer. So it is never fit in one frame. So the network layer has to divide the data into small pieces. Each of the frames is called as a fragment. This process is called as fragmentation.

The Internet Protocol (IP) implements datagram fragmentation, breaking it into smaller pieces, so that packets may be formed that can pass through a link with a smaller maximum transmission unit (MTU) than the original datagram size.

What is a fragment in CN?
Nasir said:   8 years ago
Fragmentation is dividing packets and then they need to be transmitted.
