Question

Which of the following is NOT an advantage of a MODEM?
1. Speed
2. Malware attack
3. Automatic dialling
4. Signal conversion

Answer 1

Correct Answer - Option 2 : Malware attack

Analysis:-

MODEM:

• It stands for 'Modulator–Demodulator’.
• It can be defined as a device that modulates signals to encode digital information and demodulates the signal to decode the transmitted information.

Advantages:

• It facilitates short-range wireless connectivity.
• Since telephone lines are used it has high transmission speed.
• It can accept commands from other computers for communication the process is known as Auto-dialing. 
• The MODEM is a network hardware device that converts digital signals into analog signals and analog signals into digital signals.

Disadvantages:

• It makes our system more prone to malware attacks and hackers.
• MODEMs that use dial-up connections need telephone lines to access the internet. If the line is disrupted we won’t be able to access the internet.

Clearly, we can say Malware attack is not an advantage of MODEM.
