220-801 · Question #972

Which of the following Internet connection types would have the MOST available bandwidth and highest transmission speed?

The correct answer is C. Cable. Among the listed options, cable internet consistently offers the highest bandwidth and transmission speeds for residential connections. Dial-up is the slowest, satellite has high latency, and DSL speeds are limited by distance from the central office.

Why each option

Among the listed options, cable internet consistently offers the highest bandwidth and transmission speeds for residential connections. Dial-up is the slowest, satellite has high latency, and DSL speeds are limited by distance from the central office.

ADSL

DSL (Digital Subscriber Line) uses telephone lines and its bandwidth degrades significantly with distance from the provider's central office, limiting maximum real-world speeds.

BDial-up

Dial-up uses a standard analog telephone line to connect at a maximum speed of 56 Kbps, making it the slowest internet connection type available.

CCableCorrect

Cable internet uses the existing coaxial cable television infrastructure and the DOCSIS standard to deliver downstream speeds that commonly range from 100 Mbps to over 1 Gbps, making it the fastest option among those listed. It does not suffer from the distance limitations of DSL or the high latency and low bandwidth caps of satellite and dial-up connections.

DSatellite

Satellite internet has high latency due to the round-trip signal distance to orbiting satellites and historically lower bandwidth compared to cable, though newer LEO services are improving this.
