What is difference between Bandwidth and Allowed Data Transfer?
Bandwidth / Data Transfer = Amount of data that is transfered through a server in a specified time. ( Bandwidth is measured in bps or Mbps.)As a client it is important for you to understand Data Transfer or bandwidth as most of the hosting companies have limitation in terms of the allowed data transfers per account / website. This in terms means that their is a limit to the amount of data that can be transfered per website that you host with the hosting company.
How do analyse how much data transfer / Bandwidth my website needs?
The rule for understanding the bandwidth requirement is quite simple and can be associated with some standard variables.* The number of pages and average page size of the website
* The number of visitors that you are expecting on your website
* Email usage that may be associated with your account
For Example if your average page views are 1000 per day and each page is of the size 50 kb then per day bandwidth usage would be 50,000 kbps. If you multiply this with 30 then you can have the monthly bandwidth requirement for the website.
Also you should keep in account other bandwidth usage like email Ftp, Sound, video clips etc and should always look at a higher limit or plan for the website to ensure that your website is not down because your website is assigned a low allowed data transfer limit.
