Which of the following is MOST likely to use an RJ-11 connector to connect a computer to an ISP using a POTS line?
A. Multilayer switch
B. Access point
C. Analog modem
D. DOCSIS modem
Correct Answer: C
Explanation/Reference:
Before ADSL broadband connections became the standard for Internet connections, computers used analog modems to connect to the Internet. By today’s standards, analog modems are very slow typically offering a maximum bandwidth of 56Kbps.
An analog modem (modulator/demodulator) converts (modulates) a digital signal from a computer to an analog signal to be transmitted over a standard (POTS) phone line. The modem then converts (demodulates) the incoming analog signal to digital data to be used by the computer. An analog modem uses an RJ-11 connector to connect to a phone line (POTS)in the same way a phone does.
