A source sends one packet of 1000 bytes to a destination through two routers over three links, each of 10 Mbps. Ignoring propagation, queuing and processing delays, the total time taken for the packet to reach the destination with store-and-forward switching is

  • A0.8 ms
  • B1.6 ms
  • C3.2 ms
  • D2.4 ms
Correct answer: D

Explanation

Each link needs 8000 bits / 10 Mbps = 0.8 ms to transmit the whole packet, and with store-and-forward the three transmissions occur one after another, giving 2.4 ms.
