📚 Understanding Input vs. Output
In the world of computers, input and output are fundamental concepts that describe how information enters and leaves a system. Understanding the difference is crucial for grasping how computers process data and interact with the outside world.
⌨️ What is Input?
Input refers to the data or signals that are sent to a computer system. This can come from various sources, such as a keyboard, mouse, microphone, or even another computer. The computer then processes this input to perform specific tasks.
🖥️ What is Output?
Output is the result of the computer's processing, presented to the user or another system. This can take many forms, including text on a screen, sound from speakers, a printed document, or data sent to another device.
