I was having a speed test done when I saw an advertisment for t1 and I saw that it was around a 100-200 dollars a month. How does it work? Why are the prices so high? How fast is it? Is it faster than Fios? I tried googling it but didnt get anything that i could understand.

T1 is an AT&T devised term for commercial grade Internet access using DS1 circuit types.
It also represents a speed rating of 1.544Mb/s.
If you have FiOS it is considerably faster than T-1 speed. Most cable Internet access packages are 7X-8X faster than T-1 speeds. My AT&T/Yahoo DSL package is 1.5X-2X faster than T-1.
One of the key factors about T-1 access for a business is the Service Level Agreement (SLA) that can be attained with the T-1 circuit lease. Most SLAs have a stipulation in the contract that if for any reason of the provider's fault, you can't access the Internet via your T-1 for 24 hours or more you are not required to pay for the Month of the disruption.
This makes more sense for businesses as they can use the cost of the T-1 as a "business tax write-off".
Most successful small businesses lease T-3 circuits. T-3 is also a AT&T created term and represents a speed of 44.736Mb/s. Other than the speed of the connection and the price, the SLA and so on are the same.
Contrary to a common misconception amongst some of the junior tech types, T-3 is not even close to the fastest commercial grade circuit available.
OC-768 is the fastest proven speed that has been operational on a transcontinental link. It's speed is 40Gb/s.
Most ISPs order OC-192 backbone services and have typically a primary and a secondary OC-192 backbone.
OC-192 operates at 9953.28 Mbit/s.

T1 is a line speed standard, also T3, they are used for business and commercial purpose with same up/down speed, also a service contract to ensure the down time is minimized. hence the highcost.

Well, T1 is just really fast internet connection...
* DS0 - 64 kilobits per second
* ISDN - Two DS0 lines plus signaling (16 kilobytes per second), or 128 kilobits per second
* T1 - 1.544 megabits per second (24 DS0 lines)
* T3 - 43.232 megabits per second (28 T1s)
* OC3 - 155 megabits per second (84 T1s)
* OC12 - 622 megabits per second (4 OC3s)
* OC48 - 2.5 gigabits per seconds (4 OC12s)
* OC192 - 9.6 gigabits per second (4 OC48s)
And works through high tech Fiber Optics ran right to your computer. i found some websites on the topic, check it out.

this would be the type of service that a company or school would get where there are many computers online at the same time
