Consider the following statements regarding ethernet:
I – Ethernet supports 48 bit long address.
II – Ethernet transmits only packets.
III – Ethernet works on the network layer.
IV – Minimum frame size in ethernet is 64 bytes.
V – To reduce the probability of collision on retransmission exponential backoff algorithm is used.
(A) I, II and IV
(B) II and III
(C) I, IV and V
(D) All statements are incorrect.
Answer: (C)
Explanation: I – Address in ethernet is MAC address which is 6 bytes long(48 bit).
II – Ethernet transmits frame as well as packets(where each frame is wrapped with a packet that contains MAC address of both sender and receiver)
III – It works at the data link layer, which checks how data can be transmitted from one device to another device (point to point communication) over the same network segment.
IV – Minimum size of the frame in ethernet is 64 bytes and the maximum is 1518 byte.
So, option (C) is correct.
