Packet Switching

Switching is a technique that helps us make efficient use of physical links in a network of computers. There are two basic techniques:

Datagram

  • Technical Datagram: Each packet fragment is sent with sufficient information, such that the network can simply route the fragment to the data terminal equipment.
  • Considered the most sensitive method.
  • No call setup phase.
  • The passing of data is more secure.
  • Not all packets follow the same route.
  • Packets can reach the destination in disarray because
