SPEED! How fast is FAST?
It's easy to get your head spinning trying to understand speed as it relates to technology. There are so many claims of speed and "fastest this" and "fastest that", especially when discusing internet access. It can be confusing, or worse yet, deceiving.
When you hear speeds mentioned in tecnology, you hear phases like mega-hertz, giga-hertz, bits per second, kilo-bytes per second, and while they are all technically accurate, it's so much easier to simply use "miles per hour" when comparing things. Technically inaccurate, of course, but easier to grasp. |

When it comes to internet access, we all probably remember 56K dialup modems. "K" stood for kilo-bits per second, but for comparison we'll just say 5 miles per hour.
With DSL, we can have speeds of 1500 miles per hour. Actually, Internet service providers are offering even faster speeds, up to 3000 miles per hour. Cable internet claims speeds up to 3000-6000 miles per hour these days.
The trick with DSL is that there is a speed difference between download speeds (when something comes down from the Internet into your PC) and upload speeds (when you send something back to the Internet).
Download speeds affect you when you surf the web, download pictures or video, and when you receive email. Upload speeds usually only affect you when you send email, or when you use remote access programs, like GoToMyPC.
With DSL you can have download speeds of 1500 miles per hour, or even 300 miles per hour, but upload speeds are about 380 miles per hour.
A T1 on the otherhand is the same speed in both directions. You can send email just as fast as receive email. A T1 is 1500 miles per hour in both directions. This is something most noticable when you use remote access software like GoToMyPC.
