What is bandwidth (i.e., traffic)?

The term bandwidth has two meanings (in the context of computers and data transmission):

The first is a more engineering term that is used to measure how fast a web server can transmit web data onto the Internet to get it going to your reader's computer (i.e., how much data per second). 420 Design Hosting servers have redundant network connections to the Internet backbone and have those connections rated to be the highest speed possible using the latest technology networking equipment.

The second definition is a more common, albeit informal, usage that means the amount of traffic your email and web viewing usage has come to our servers. In simple terms, if a 1MB music audio clip was listened to (downloaded) 500 times, then that would constitute a bandwidth usage of 500 MB.
