The transport Layer

Communication  between  computers is handled by the transport layer which  is comprised of transmission control  protocol (TCP) and the users  datagram protocol ( UTP). This  layer divides the data into  logical units called packets before  transmitting them. TCP offers  a reliable transport of data whereas UDP does not. TCP is a connection  oriented protocol  that ensure that data is transmitted properly t the destination. If there is an  error in data transmission. TCP takes the responsibility of transmitting  data again  to the  destination. However UDP being  connectionless it does  not ensure the data packets  have reached the destination properly. However both TCP and UDP seek the  help  of IP so route the information  to the appropriate destination.
