🔹 History of the Keyboard
From Typewriters to Modern Computers
The keyboard’s story begins with the mechanical typewriter invented in the 1860s. The famous QWERTY layout was designed in 1873 by Christopher Sholes to prevent typewriter jams by spacing out commonly used letters.
As computers developed in the mid-20th century, keyboards replaced punch cards and switches, becoming the main way to input text. Early computer keyboards were large, mechanical, and based on typewriter designs.
Keyboard Layouts
QWERTY – the most common layout worldwide.AZERTY – used in France and Belgium.
DVORAK – designed for speed and efficiency.
Colemak – a modern layout optimized for comfort.
Today, most of us still use QWERTY, but other layouts exist for faster typing or regional preferences.

🔹 How a Keyboard Works (Technical Breakdown)
Inside every keyboard, there are layers:
Keycap – the part you press.Switch or Membrane – detects the press.
Circuit Board – sends the signal.
Controller – translates the signal into input for the computer.
When you press a key, an electrical signal is sent to the computer, telling it which key was pressed. If something interrupts this process (like dust, broken switch, or faulty wiring), the key may fail.
🔹 Common Keyboard Problems
Sticky Keys – caused by dirt or spills.Dead Keys – no response when pressed.
Double Typing – one press registers twice.
Numeric Pad Not Working – Num Lock issue.
