ISP Access Types
Many ISPs offer several different levels of internet connectivity using a variety of technologies, including cable, fiber optics, DSL and satellite. Each of these delivery methods has a very distinct impact on the end-user experience, offering a wide range of speed and reliability.
For example, DSL service is a dedicated line and will therefore not be subject to bandwidth loss caused by "peak times" like its shared-connection cable counterpart. However, cable is inherently faster, and DSL speeds can also degrade as the distance between you and the target central office increases. Fiber optics provide the same dedicated line as DSL, sending the data signal over fiber optic glass cables instead of copper, making it significantly faster, but also more expensive.
However, oftentimes the choice of an access type might be limited to your geographic location as fiber, cable and even DSL might not be available in some remote or rural areas. This is when a satellite service might be the only viable option.
