What Is a Keyboard Buffer?

A keyboard buffer is a very small partition of memory that is usually stored in the computer memory in random access memory (RAM) and captures all the keystrokes made on a keyboard. Keystrokes are stored because there is a slight delay between when the key is pushed and when it displays on the screen. By capturing the keystroke, processing is easier and more accurate for the computer. Unlike what a user sees on the screen, not all keystrokes are captured, such as when a user pushes the “Delete” key. The keyboard buffer can be manipulated to hold more information, and there are also malicious programs designed to spy on the buffer’s data.
