FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A telephone network is an example of a circuit switched network. Therefore, the correct answer is option (b)

Detailed explanation-2: -Circuit switching is used for connections that must be continuous for long periods of time, such as long-distance communication. Traditional telephone systems–i.e., landlines–are an example of a technology that uses circuit switching.

Detailed explanation-3: -The defining example of a circuit-switched network is the early analog telephone network. When a call is made from one telephone to another, switches within the telephone exchanges create a continuous wire circuit between the two telephones, for as long as the call lasts.

Detailed explanation-4: -Circuit switching was designed for voice applications. Telephone is the best suitable example of circuit switching. Before a user can make a call, a virtual path between the called subscriber and the calling subscriber is established over the network.

Detailed explanation-5: -Landlines and VoIP transmit voice data in different ways The old telephone system (PSTN) uses circuit switching to transmit voice data, whereas VoIP uses packet switching. The replacement of traditional landlines by internet-based communication protocols is mainly due to the benefits of packet switching vs.
