Circuit Switching MCQ for Gate/Net and other Exam

  1. Principle of Circuit Switching is…
  • A. A dedicated physical path Between Sender and Receiver
  • B. Transfer Data with Packet form
  • C. Resource allocation after three way hand shaking
  • D. Working on Data Link Layer
  • None of the above

Points to remember before going to examination hall
Circuit Switching-:

  1. It is done on Physical Layer
  2. In Circuit Switching before sending any data to receiver a dedicated physical path has been establish.
  3. In first step connection will be establish with sending one starting bit data. This data is responsible for making a connection between sender and receiver.
  4. Addressing is involve in connection establishment phase.
  5. All the resources will be allocated at the time of connection establishment phase.
  6. After sending first bit all the path is dedicated and data is moving like a pipeline with following that first bit in data transfer phase. For this data is transfer very fast in circuit switching.
  7. This dedicated pipeline is responsible to send data and remains open until send all data to receiver.
  8. In Circuit switching data is flow with a physical path like a dedicated single path.
  9. After sending all data to receiver connection will be terminated in last phase.
  10. It is generally used in voice communication.
  11. Total time taken for packet to transfer from sender to receiver in Circuit switching
  12. Total time= Connection establishment time(It is given in Question)+Data Transfer(TT+TP)+ Connection Termination time(It is given in Question).
  13. Efficiency in Circuit Switching is very low because of resource allocation in advance.
