Your Keyboard Remembers Your Future Typing

Your computer uses a temporary holding area called a buffer to save keystrokes before processing them. This allows you to type faster than the computer can actually display the characters on your screen.

Have you ever noticed that you can keep typing even when your computer screen momentarily freezes? That is thanks to the keyboard buffer, which silently stores your inputs in a queue. It ensures that no matter how fast you type, your machine captures every single stroke in the correct order. Without this memory space, your computer would likely lose any data typed during a brief system lag.
