Which of the following is an internet accessing technique where a computer uses its modem to dial a telephone number given to the user by an Internet Service Provider?

Correct option is B

A Dial-up Connection is an internet accessing technique that uses a modem to connect to an ISP by dialing a telephone number. It relies on the Public Switched Telephone Network (PSTN) to establish a connection, and the data transfer occurs over the same lines as voice calls.
Important Key Points:
1. Dial-up connections are relatively slow, with speeds up to 56 Kbps.
2. They require a telephone line and a modem to function.
3. These connections were widely used before broadband and DSL technologies became popular.
Knowledge Booster:
1. Digital Subscriber Line (DSL): A faster, always-on internet connection that uses telephone lines but does not interfere with voice calls.
2. Broadband Connection: Provides high-speed internet using technologies like DSL, cable, or fiber optics.
3. ISDN Service: A digital network service for transmitting voice and data, faster than dial-up but less common today.
