What is BANDWIDTH ?

 Bandwidth is used to measure the data throughput of a channel or connection. It's the amount of data that can be sent over a connection in a given amount of time without distortion. It should not be confused with band.

Bandwidth describes the maximum data transfer rate of a network or Internet connection. It measures how much data can be sent over a specific connection in a given amount of time. For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps (125 megabytes per second). An Internet connection via cable modem may provide 25 Mbps of bandwidth.

The term bandwidth refers to the transmission capacity of a connection and is an important factor when determining the quality and speed of a network or the internet connection. 

There are several different ways to measure bandwidth. Some measurements are used to calculate current data flow, while others measure maximum flow, typical flow, or what is considered to be good flow.

Bandwidth is also a key concept in several other technological fields. In signal processing, for example, it is used to describe the difference between the upper and lower frequencies in a transmission such as a radio signal and is typically measured in hertz (Hz).

Bandwidth can be compared to water flowing

through a pipe. Bandwidth would be the rate at which water (data) flows through the pipe (connection) under various circumstances. Instead of bits per second, we might measure gallons per minute. The amount of water that possibly can flow through the pipe represents the maximum bandwidth, while the amount of water that is currently flowing through the pipe represents the current bandwidth.
