Answer:
<u>The correct answer is B. The use of an analog modem to transmit data over voice telephone lines.</u>
Explanation:
<u>Dial-up</u> is the oldest Internet connection method and was the only one used when the Internet took its first steps. Access is made by the user through an analog modem and a conventional telephone line. It is less and less used, since the data transmission capacity does not exceed 56 kbps, which makes navigation very slow, unstable and keeps the telephone line busy when connected to the internet. With the popularization of broadband access services and their very affordable prices, <u>dial-up</u> access is virtually obsolete.
The telecommunications device that is widely used in industries that require closed communication are walkie-talkies. Correct answer: D
Walkie-talkies are hand-held, portable, two-way radio transceivers which enable secure communication between the two points, without being part of a network.
