Input

Input refers to the data or instructions that are entered into a computer for processing. Inputs can come from various sources, such as a keyboard, mouse, scanner, or another computer. The process of inputting involves the transfer of data from the source to the computer's Central Processing Unit (CPU), where it is processed and converted into output.

Types of Input

There are several types of input, including:

• Direct Input: This is the most common type of input, where data is entered directly into the computer via an input device such as a keyboard or mouse.

• Indirect Input: In this type of input, data is not entered directly into the computer but is first recorded on a medium such as a disk or tape before being entered into the computer.

• Automatic Input: This type of input involves the use of devices that automatically input data into the computer without human intervention. Examples include sensors and barcode readers.

Input Devices

Input devices are hardware components that allow users to enter data into a computer. Some common input devices include:

• Keyboard: This is the most common input device, used for typing text and numbers into a computer.

• Mouse': This device is used to control the cursor on the screen, allowing users to select and move items.

• Scanner: This device is used to convert physical documents into digital format.

• Microphone: This device is used to input sound into a computer, often for voice recognition or audio recording.

Input in Programming

In Computer Programming, input refers to the data that a program receives during its execution. This data can come from a variety of sources, such as user input, files, or other programs. The way a program handles input can significantly affect its functionality and efficiency.
