Question

The network layer is concerned with __________ of data.

(a) bits

(b) frames

(c) packets

(d) bytes

The question was asked at a job interview.

Origin of the question is Network Layer in section OSI Model of Computer Network

Answer 1

The correct answer is (c) packets

The best explanation: In computer networks, the data from the application layer is sent to the transport layer and is converted to segments. These segments are then transferred to the network layer and these are called packets. These packets are then sent to data link layer where they are encapsulated into frames. These frames are then transferred to physical layer where the frames are converted to bits.
