Answer: A

Advantage of Packet Switching over Circuit Switching :

  • More efficient in terms of bandwidth, since the concept of reserving circuit is not there.
  • Minimal transmission latency.
  • More reliable as destination can detect the missing packet.
  • More fault tolerant because packets may follow different path in case any link is down, Unlike Circuit Switching.
  • Cost effective and comparatively cheaper to implement.
