Overview
Input refers to the data fed into a computer system for processing. Inputs can be supplied through various input devices such as keyboards, mice, scanners, or storage devices like disk drives. Think of input as the means by which data and commands enter into a computer system for interpreting and executing tasks.
Examples
- Keyboard Input: Typing text into a word processor.
- Mouse Input: Clicking and dragging graphic elements in design software.
- Scanning documents: Using a scanner to digitize paper documents.
- Downloading Files: Receiving data from a cloud storage service.
Frequently Asked Questions (FAQs)
Input in computing refers to the data or instructions entered into a computer system for processing, typically through input devices or storage devices.
Common input devices include:
- Keyboards
- Mice
- Scanners
- Microphones
- Digital cameras
Input is the information entered into a computer system, while output is the information produced by the computer after processing the input, typically displayed on a screen, printed on paper, or stored for future use.
Yes, storage devices like hard drives, SSDs, and flash drives can act as input sources when they provide data to the computer.
Software interprets the input data and executes commands or operations accordingly. It acts as a mediator between the hardware input device and the desired output.
- Output: Data produced by a computer after processing input.
- Input Device: Hardware used to provide data input to the computer system.
- Data Processing: The manipulation of input data to generate meaningful information.
