Input/output operations, often abbreviated as I/O operations, refer to the communication between a computer system and the outside world. This encompasses any process where data is transferred into the system (input) or out of the system (output). Input can come from various sources, such as keyboards, mice, microphones, scanners, or network connections. Output is typically directed to devices like monitors, printers, speakers, or network interfaces.

These operations are fundamental to the functioning of any computer. Without them, a computer would be isolated, unable to receive instructions or display results. The central processing unit (CPU) of a computer performs calculations and processes data, but it relies on I/O operations to get the data it needs to process and to send the results of its processing to users or other systems.

I/O operations are managed by the operating system, which acts as an intermediary between the hardware and the application software. The operating system provides mechanisms and drivers that allow programs to interact with I/O devices in a standardized way, abstracting away the complexities of the underlying hardware. This abstraction makes it easier for developers to write applications that can work with a wide range of input and output devices. Different types of I/O exist, including character-based I/O, block-based I/O, and memory-mapped I/O, each suited for different types of devices and data transfer needs.
