In a packet switching network, if the message size is 48 bytes and each packet contains a header of 3 bytes. If 24 packets are required to transmit the message, the packet size is ________.
(A) 2 bytes
(B) 1 bytes
(C) 4 bytes
(D) 5 bytes


Answer: (D)

Explanation: There are 24 packets and 48 byte of data, So 48 / 24 = 2 byte data for each packet.
Header size is 3 byte
2 + 3 = 5 byte will be the size of data packet.
So, option (D) is correct.
