Bandwidth or data transfer are terms referring to the amount of data that can be transferred in and out within a given period of time, usually monthly. When a visitor browses a website, he or she has to download the HTML, images, scripts and other files to view the web page. The amount of transfer the visitor uses counts towards your allocated monthly amount of data transfer. For example, if the visitor retrieves an image that is 2KB and one HTML page at 4KB, then the total data transfer for that session is approximately 6KB. However, there are other factors that may influence your data transfer measurements, such as, FTP, SSH and other applications accessing files on your web hosting account.
