As you probably have guessed this shirt is a rip-off of the signs street people hold up as you drive or walk by. Most people don't know what bandwidth means. Don't listen to Wes Sinclair, its not exactly your internet connection speed. Bandwidth is defined as, "The amount of data that can be passed along a communications channel in a given period of time." Communications channel applies to a lot of things. For example, a Geforce 2 Ultra has 7.2 GBps bandwidth. This mean that approximately 7730941133 bytes of information can be transferred from the memory of the card to the processor in one second. Of course, this is theoretical bandwidth and is never actually achieved due to various bottlenecks. Bandwidth can also apply many other things, like the amount of memory bandwidth a computer has. DDR SDRAM offers a theoretical rate of 2.1 GBps. This is a quote I got off of slashdot, "Never underestimate the bandwidth of a 747 filled with CDs." Be sure to note that bandwidth does not necessarily mean you will get low ping times.
