Difference between Bandwidth and Throughput

Bandwidth:
It is defined as the potential of the data that is to be transferred in a specific period of time. It is the data carrying capacity of the network/transmission medium.

Throughput:
It is the determination of the amount of data is transmitted during a specified time period via a network, interface or channel. Also called as effective data rate or payload rate.

Difference between Bandwidth and Throughput:



S.No. Comparison Bandwidth Throughput
1. Basic Data capacity is travelled via a channel. Practical measure of the amount of data actually transmitted through a channel.
2. Measured in Bits Average rate is measured depending on bandwidth. It is measured in terms of bits transferred per second (bps).
3. Concerned with Transfer of data by some means. Communication between two entities
4. Relevance to layer Physical layer property. Work at any of the layers in the OSI model.
5. Dependence Not depend on the latency. It depends on the latency.
6. Definition It refers to the maximum amount of the data that can be passed from one point to another. It is considered as the actual measurement of the data that is being moved through the media at any particular time.
7. Effect It is not affected by physical obstruction because it is a theoretical unit to some extent. It can be easily affected by change in interference, traffic in network, network devices, transmission errors and the host of other type.
8. Real world Example(Water Tap Example). It is the speed of tap at which water is coming out. It is the total amount of water that comes out.
