What is the most widely available method of internet distribution in the United States?

Cable is the most widely available method of internet distribution in the United States after telephone lines. The cable network was originally laid to channel subscription TV to US homes. Making it an ideal medium for the provision of the internet. The cable TV system in the United States was first laid in the 1950s. TV signals were sent along the cables as analog radio frequency transmissions. The cables carried VHF video and FM radio. During this century, the US cable network has switched over to digital transmission. Speeds were improved by replacing the long-distance sections of then network with fiber-optic, although the last stretch to each home is still carried on coaxial cable.

Is cable internet good for gaming?

The reliable connections of cable internet make it a good choice for online gaming by regular residential users. Those who want to set up a games service might be better off getting a commercial internet service, however. This is because a game server is expected to send out a large amount of data, which the upload bandwidth of a standard cable internet contract wouldn’t offer, resulting in slow upload speeds.

Is cable internet faster than DSL?

In general, cable internet speeds are faster than DSL internet. However, some providers have not invested sufficiently in their infrastructure in all locations and in other areas might overload their network with too many customers in order to increase profits. You will have to test your local service to check whether it has faster internet broadband connections than the DSL service available in your locale.

Is fiber optic internet faster than cable?

Most cable internet services are partially carried by fiber-optics. The more fiber-optic cables in a network, the faster the service will be.
