When you press a key on your keyboard, the letter instantly appears on your screen — but have you ever wondered how that happens? The communication between a keyboard and a computer is simple yet fascinating. Whether you’re typing a message, playing a game, or working on important documents, your keyboard is constantly sending signals to your computer so it can understand your input.
In this article, we’ll explain this process in a simple and human-friendly way, and also give an example using the Portronics Key9 Combo, a popular keyboard and mouse set you can find on SK Gadgets, our trusted gadget and accessories store.
What Happens When You Press a Key?
When you press a key on your keyboard, several things occur within a fraction of a second:
- Key Press is Detected: Each key on a keyboard has its own position in a grid called a key matrix. When a key is pressed, it completes a tiny electrical circuit.
- Signal is Converted to a Code: The keyboard has a small chip called the keyboard controller, which converts this electrical signal into a digital code. These codes are known as scan codes.
- Computer Receives the Code Through the Connection: The keyboard sends these scan codes to the computer through either:
- USB cable
- Wireless receiver (Bluetooth / 2.4GHz dongle)
- Operating System Translates the Code: Your computer reads the scan code and the operating system (like Windows or macOS) translates it into the character you see on the screen.
- You See the Output: Finally, the letter appears in the text field where you are typing.
So from pressing a key to seeing the letter on the screen, the process is fast and automatic — all happening in milliseconds.
Example: Portronics Key9 Combo
To understand this better, let’s look at a real-world example: the Portronics Key9 Combo.
This combo includes:
- A Wireless Keyboard
- A Wireless Mouse
- A Nano USB Receiver (to connect to your computer)
When you plug the nano USB receiver into your laptop or desktop:
- The receiver communicates wirelessly with the keyboard
- Every key press is converted into data and transmitted instantly
- The computer interprets the data and displays the characters you type
This is why the Key9 Combo feels smooth and lag-free while typing and browsing.
