Question

Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, Sketch the waveform produced by A when “$” is sent. Also mention the OSI layer that is responsible for this. (Note: double quotes are not included, only $)

Answer 1

Answer:

Physical and data link layer.

Explanation:

The ethernet cable is used at the physical layer. The physical layer consists of hardware components. This layer is responsible for transmission of data bits between two nodes via a physical wire. The data link layer provides the means in which data packets are transmitted from one node to another.

Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the packets would be sent from computer A to computer B if computer B is free if not it would wait until computer B is not transmitting before it can start sending data packets to computer B.
