Networking MCQ Questions and answers- Technical Aptitude

A. Simplex:
Simplex communication is a method of communication where transmission occurs in only one direction. It does not support two-way communication.

B. Four wire circuit:
A four-wire circuit refers to a communication channel that uses separate wires for transmission and reception, allowing for simultaneous two-way communication. However, this option does not describe the scenario where only one direction is allowed at a time.

C. Full Duplex:
Full duplex communication is a method where transmission can occur simultaneously in both directions. It allows for two-way communication simultaneously, which is not the case in the given scenario.

D. Half Duplex:
Half duplex communication is the correct answer. In this method, transmission can take place in both directions, but only one direction can occur at a time. The communication switches between the two directions, allowing communication in both directions but not simultaneously.

Therefore, the correct answer is:
D. Half Duplex

Mess Topology is a network setup where each computer and network device is interconnected with one another, allowing for most transmissions to be distributed, even if one of the connections go down. This topology is not commonly used for most computer networks as it is difficult and expensive to have redundant connection to every computer. However, this topology is commonly used for wireless networks.

Start and stop bits are not needed in synchronous transfer of data. So, it is 2400/8=300.
