The capacity of data that may be moved between the site, its users, and the servers are known as bandwidth. It refers to the speed with which a website user may connect to the server. Bandwidths are measured in megabytes per second (MB/s) or gigabytes per second (GB/s) (Gigabytes per Second). Bandwidth is usually calculated as part of monthly hosting packages.
As an example, a supplier might offer 1GB of bandwidth per month or 5GB of bandwidth per month. Consider bandwidth to be a road you're traveling on: you can take a good, wide highway or a narrower one. A broader road has a greater capacity to accommodate traffic than a tiny one. As a result, the wider the road is, the faster you can travel. As a result, bandwidth might be considered a capacity (not speed).
The bigger (wider) the bandwidth, the greater the data-carrying capacity and, as a result, the amount of data transported. As a result, the data-carrying capacity is more important than the speed.
