The question asks to identify the specific device or programme responsible for transmitting computer data over telephone and cable lines.
Modem Function Explained
A **modem** is the device that fulfills this role. Its name comes from its function: Modulator-Demodulator.
- Modulation: Converts digital data from a computer into analog signals suitable for transmission over phone or cable lines.
- Demodulation: Converts incoming analog signals back into digital data that the computer can understand.
This process allows computers to communicate over long distances using existing communication infrastructure like telephone lines and coaxial cable networks. It is essential for dial-up, DSL, and cable internet connections.
Other Options Analysis
The other options are incorrect because they serve different purposes:
- Motherboard: The main circuit board of a computer; it connects all the internal components but does not transmit data over external lines.
- Monitor: A display screen that shows the output from the computer; it receives data but does not transmit it over phone lines.
- Mouse: An input device used to control the cursor on the screen; it sends simple commands to the computer, not data over communication lines.
Therefore, the modem is the correct device for transmitting data over telephone and cable lines.
