Write notes on four basic functions of a computer with examples and references???

1. Input: The input function of a computer involves receiving data or instructions from external sources. This can include input devices such as keyboards, mice, scanners, and microphones. For example, when a user types a document on a keyboard, the computer receives the input and processes it accordingly.

2. Processing: The processing function of a computer involves manipulating and transforming data using algorithms and software programs. This can include tasks such as calculations, sorting, and data analysis. For example, when a computer runs a spreadsheet program to perform complex calculations, it is utilizing its processing capabilities.

3. Output: The output function of a computer involves displaying or presenting processed data to the user in a readable format. This can include output devices such as monitors, printers, and speakers. For example, when a computer prints a document on a printer or displays a video on a monitor, it is utilizing its output capabilities.

4. Storage: The storage function of a computer involves saving and retrieving data for future use. This can include storage devices such as hard drives, solid-state drives, and cloud storage. For example, when a computer saves a file on a hard drive or accesses data from a cloud storage service, it is utilizing its storage capabilities.
