- Throughput

Question 2

What is DELAY

Answer 2

Delay is a measure how long it takes for a bit of data to travel across the network from one compute to the other.

Question 3

What are types of delay

Answer 3

PROPAGATION DELAY: It defined as the time to travel across medium.
SWITCHING DELAY: It is the time required for network component (hub, bridge, packet switch) to forward data.
ACCESS DELAY: It is the time required to get control of medium (CSMA/CD, token).
QUEUING DELAY: It is the time required in packet switches.

Question 4

What is Throughput

Answer 4

Throughput is a measure of the rate at which data can be sent through the network.

Question 5

What is bandwidth

Answer 5

The throughput capability of the underlying hardware is called bandwidth.

Question 6
