带宽：
它被定义为在特定时间段内要传输的数据的潜力。它是网络/传输介质的数据承载能力。
吞吐量：
它是确定在指定时间段内通过网络、接口或通道传输的数据量。也称为有效数据速率或有效载荷速率。
带宽和吞吐量的区别：
| 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. |
