Which one is not an output device?
- A.
Printer
- B.
Monitor
- C.
Keyboard
- D.
Modem
Correct Answer
C. KeyboardExplanation
A keyboard is not an output device because it is used to input data into a computer, rather than displaying or producing any output. Output devices, on the other hand, are used to present or transmit information from a computer to the user or another device. Examples of output devices include printers, monitors, and modems, which respectively produce hard copies of documents, display visual information, and transmit data to other devices.Rate this question:

Which one works as an output and input device?
- A.
Modem
- B.
Scanner
- C.
Mouse
- D.
Monitor
Correct Answer
A. ModemExplanation
A modem can work as both an output and input device. It serves as an output device by converting digital signals from a computer into analog signals that can be transmitted over telephone lines. On the other hand, it acts as an input device by converting analog signals from telephone lines into digital signals that the computer can understand. Therefore, a modem is capable of both sending and receiving data, making it an output and input device.Rate this question:

C. Magnetic TapeExplanation
A magnetic tape is a secondary storage device that follows the sequential mode of access. It stores data in a linear manner, allowing for sequential reading and writing operations. This makes it ideal for applications that require large amounts of data to be stored sequentially, such as backup systems or archival storage. Unlike magnetic disks or optical disks, which allow for random access to data, magnetic tapes must be accessed sequentially from the beginning to reach a specific piece of information. Therefore, the correct answer is Magnetic Tape.Rate this question:
