Computer Input and Output Devices Quiz

The I/O Subsystem of a computer provides an efficient mode of communication between the central system and the outside environment. It facilitates the interaction between the computer and peripheral devices, enabling data transfer and control.

The Input Output Interface provides a method for transferring information between internal storage and external I/O devices. It enables the connection and communication between peripherals and the central processing unit, resolving differences that exist between them.

i) Monitor: Displays visual output from the computer. ii) Keyboard: Allows input of textual and command data. iii) Mouse: Enables user interaction through pointing and clicking. iv) Printer: Produces hard copy output. v) Magnetic tapes: Used for long-term data storage and retrieval.
