Which of the following is a type of Internet connection that uses telephone lines?
- (a)DSL
- (b)Cable
- (c)Fiber Optics
- (d)Satellite
Correct — A, DSL (Digital Subscriber Line). DSL delivers broadband internet over the same copper telephone wires used for landline calls, using frequencies above the voice band so internet and phone service can run over one line at the same time.
- (b)Cable — Cable internet runs over the coaxial cable used for cable television, not over telephone lines.
- (c)Fiber Optics — Fiber-optic internet uses dedicated optical-fibre cable, not the copper telephone network.
- (d)Satellite — Satellite internet is wireless — it communicates with an orbiting satellite via a dish and needs no telephone line at all.
Internet connections differ mainly by the physical medium carrying the signal: DSL uses existing copper telephone lines, cable uses coaxial TV cable, fibre uses dedicated optical cable, and satellite uses a wireless link to space. DSL's advantage was leveraging telephone infrastructure already installed in most homes, making it one of the earliest widespread broadband options.
The trap is treating all 'wired' options as interchangeable — cable and fibre are also wired but use different infrastructure (TV cable / optical fibre), not telephone copper. 'Uses telephone lines' is the specific identifier that singles out DSL.
- DSL = Digital Subscriber Line, runs over copper telephone wires
- Cable internet uses coaxial television cable, not telephone lines
- Fiber optics uses dedicated optical-fibre cable for much higher speeds
- Satellite internet is wireless, via a dish and an orbiting satellite
- Confusing DSL (telephone-line broadband) with old dial-up (which blocks voice calls while connected)
- Mixing up cable and fibre-optic as the same physical medium
MPPSC computer-awareness typically asks 'which connection type uses telephone lines / coaxial cable / optical fibre' as a direct medium-identification question.
