Segmentation vs. Fragmentationa

Segmentation vs. Fragmentation:

         Segmentation is basically the same as fragmentation, with a few differences:

          Fragmentation (IP layer):

      only occurs when transmitting a packet whose size is larger than the MTU of the estination network

       Any router (connecting two different network types) could theoretically fragment ackets

      Fragmentation can almost be considered an emergency practice (what to do when omething goes wrong)

Segmentation (TCP layer):

      Occurs for all data streams, to divide the data into packets (above TCP layer data is ontinuous)

        Only the source host will segment packets

        Segmentation is a normal part of TCP’s job
