Disk I/O

Disk I/O (Input/Output) refers to the process of reading data from or writing data to a computer’s storage device, like a hard drive or SSD. It’s how the computer retrieves or saves information needed for programs and files to function. When you open a file, the system performs a disk read; when you save, it performs a disk write. Efficient Disk I/O means faster access to data, improving overall system performance. Factors like hardware speed and data organization influence Disk I/O performance, affecting how quickly tasks and applications respond.
