Which kind of connections usually provides the highest speed for internet access?

Fiber-optic connections typically provide the highest speed for internet access because they utilize light signals transmitted through glass or plastic fibers. This technology allows for significantly higher bandwidth compared to other types of connections. Fiber-optic connections can deliver speeds well into the gigabits per second range, making them ideal for high-demand applications such as streaming high-definition video, online gaming, and large file downloads.

In comparison to other options, cable connections are faster than DSL and dial-up but generally do not reach the same speeds as fiber-optic connections. Dial-up is the slowest option, operating via traditional telephone lines and offering limited bandwidth. DSL, while faster than dial-up, is also generally outperformed by fiber-optic technology, especially as distance from the service provider increases.
