What is the primary function of input devices in a computer system?

Input devices play a crucial role in a computer system by allowing users to interact with the computer and enter data. These devices include keyboards, mice, scanners, and microphones, which facilitate the input of information into the system for processing. The primary function of these devices is to convert user actions and physical signals into digital data that the computer can understand and process.

For example, when you type on a keyboard, the device translates keystrokes into commands or text that the computer can recognize. Similarly, a mouse allows for the control of the graphical interface, enabling users to navigate and select options. This interaction is essential for executing commands, inputting data, and controlling applications, making input devices indispensable for effective user engagement with the computer.

The other options relate to different functions within a computer system. Displaying output pertains to output devices like monitors or printers, performing calculations is a task mainly associated with the CPU and software applications, and storing data for retrieval involves storage devices like hard drives and SSDs. These functions, while vital to overall computer operation, do not pertain to the role of input devices specifically.
