Bandwidth is the speed of the web server while accessing its web users and It is also considered the internet link speed to which a web server is connected and is measured in Megabits per second (Mbps) or Gigabits per second (Gbps). Typically, a website with low web traffic may be utilizing 1-2 Mbps, while during a peak event or season, it can shoot up to 100++ Mbps. If the web hosting service provider does not have high bandwidth, the website might slow down when the traffic hits its peak.
