Bandwidth (computing) facts for kids

Kids Encyclopedia Facts

In computer network and computer science, digital bandwidth or just bandwidth means the amount of data that can be sent from one point to another in a certain period of time. It is measured as a bit rate expressed in bits per second (bits/s) or multiples of it (kbit/s Mbit/s etc.)

Digital bandwidth should not be confused with:

  • Network throughput: which is the average rate of successful data transfer through a connection.
  • Data transfer: which is the quantity of data transferred over a given period of time.

Bandwidth in web hosting

In web hosting, the term "bandwidth" is often used to describe the amount of data transferred to or from the website within a defined period of time. Another more specific phrase used for this meaning of bandwidth is monthly data transfer.

Web hosting companies often quote a monthly data transfer for a website, for example 500 gigabytes per month. If the total amount of data downloaded from the website in a particular month reaches this limit, the hosting company may shut off further public access to the site.
