The correct answer is: B. It utilizes existing telephone service.
Dial-up internet access is a type of internet access that uses a modem to connect to the internet through a standard telephone line. This means that you can use your existing telephone service to connect to the internet, which can be a convenient option if you don’t have a broadband connection.
However, dial-up internet access is much slower than broadband internet access. This is because dial-up internet uses a modem to convert digital data into analog signals that can be transmitted over a telephone line. This process is much slower than the process used by broadband internet, which uses a modem to convert digital data into digital signals that can be transmitted over a cable or fiber optic line.
In addition, dial-up internet is not always reliable. This is because telephone lines are often shared by multiple users, which can cause interference and slow down your internet connection. Additionally, if someone is using the telephone line while you are trying to connect to the internet, you will not be able to connect.
Overall, dial-up internet access is a slow and unreliable type of internet access. However, it can be a convenient option if you don’t have a broadband connection and you don’t need a fast or reliable internet connection.
Here is a brief explanation of each option:
- Option A: It utilizes broadband technology. This is incorrect because dial-up internet access does not use broadband technology. Broadband technology is a type of internet access that uses a high-speed connection, such as a cable or fiber optic line.
- Option B: It utilizes existing telephone service. This is the correct answer because dial-up internet access uses a modem to connect to the internet through a standard telephone line.
- Option C: It uses a router for security. This is incorrect because dial-up internet access does not use a router for security. A router is a device that connects multiple devices to a network, such as the internet. Routers can be used to provide security for a network, but dial-up internet access does not use a router.
- Option D: Modem speeds are very fast. This is incorrect because dial-up internet speeds are very slow. Dial-up internet speeds are typically around 56 kilobits per second (Kbps).
- Option E: None of these. This is incorrect because option B is the correct answer.
