The difference between network speed and bandwidth
1. The concepts of speed and bandwidth
Rate (bit/s): The transmission rate of data , also known as data rate or bit rate, often refers to the rated rate or nominal rate, rather than the actual rate running on the network.
Bandwidth (bit/s): used to represent the ability of a channel in the network to transmit data , and the "highest data rate" that a channel in the network can pass per unit time.
2. Difference:
Although bandwidth has the same unit as rate, the objects it describes are different.
For example: you are riding your bike home from school. The speed limit on the road is 80km/h. This can be regarded as the bandwidth (maximum transmission rate). The maximum speed of an electric vehicle is 40km/h, which can be understood as the rate (rated rate). , but the car will not theoretically reach a speed of 40km/h during the process.
Therefore, the bandwidth describes the attributes of the channel, while the rate describes more of the attributes of the bit data.
