Understanding Modems
A modem is a crucial device in digital communications, serving as a bridge between digital computer signals and analog telephone lines. Here’s a detailed look at its functionality:
What is a Modem?
- A modem stands for Modulator-Demodulator.
- It converts digital data from a computer into analog signals that can be transmitted over telephone lines.
- Additionally, it demodulates incoming analog signals back into digital data for the computer.
How a Modem Works
- Modulation: When a computer sends data, the modem modulates the digital signals into analog waves. This process allows the data to be transmitted over traditional phone lines.
- Demodulation: When receiving data, the modem demodulates the analog signals back into a digital format that the computer can understand.
Importance of Modems
- Internet Access: Modems are essential for connecting computers to the Internet, especially through dial-up connections.
- Communication: They enable seamless communication between devices that use different signal formats, enhancing connectivity.
Conclusion
In summary, the correct answer to the question is option 'D', the modem, as it plays a vital role in converting digital signals to analog for transmission over telephone lines and vice versa. Understanding modems is essential for grasping how digital communication works in our everyday technology.

A device that encodes digital computer signals into anolog telephone s...
Modem:
- A modem is a device that converts digital computer signals into analog telephone signals and vice versa.
- It stands for "modulator-demodulator."
- Modems are used to connect computers or other devices to the internet through a telephone line.
- They encode digital data into audio signals that can be transmitted over phone lines and decode them back into digital data at the receiving end.
ISP:
- An ISP (Internet Service Provider) is a company that provides internet access to customers.
- While ISPs are involved in connecting users to the internet, they do not directly convert digital signals into analog telephone signals and vice versa like a modem does.
Web browser:
- A web browser is a software application used to access and view websites on the internet.
- It is not involved in converting digital signals into analog telephone signals and vice versa.
Telephone Line:
- A telephone line is a physical connection that allows voice and data to be transmitted over a network.
- It is used to carry analog signals, but it does not perform the encoding and decoding of digital computer signals like a modem does.
Based on the above information, the correct answer is Modem (D) as it is the device specifically designed to encode digital computer signals into analog telephone signals and vice versa.
