What term describes the use of telephone networks to dial-up and connect to an Internet Service Provider?

• A. Dial-ups
• B. Direct
• C. Dig
• D. DNS

Answer: (A)

Dial-ups describe using the telephone network to reach an Internet Service Provider. In this arrangement, a modem on the user’s side dials the ISP’s phone number over the public switched telephone network (PSTN). When the call connects, a protocol such as PPP is used to establish an IP session so you can access the Internet. This term specifically captures the idea of dialing through telephone lines to connect to the ISP, which is why it fits the description.

The other options don’t describe this process: DNS is the system that translates domain names to IP addresses, not a method of connecting via telephone lines; Dig is a tool used to query DNS records; Direct isn’t a technical term for dialing an ISP over the phone.
