Published: 1 Sep 2025
Sometimes you might look at your keyboard and think, “Why are the letters not in A-B-C order?” It’s a common question! A keyboard may look confusing, especially if you’re new to using a computer.
But don’t worry, you’re not alone. Many people find it tricky at first. Still, this tool is super important. It’s what we use to type messages, write homework, search the internet, and even play games.
In this article, we’ll learn about what a keyboard is.
What is a Keyboard?
A keyboard is a tool we use to type letters, numbers, and symbols on a computer. It looks like a board full of small buttons called keys.
Each key sends a signal to the computer when you press it. This helps you write, give commands, and do different tasks, like typing a message, searching on Google, or playing games.
Most keyboards have keys for.
- Letters (A–Z)
- Numbers (0–9)
- Symbols (@, #, %, etc.)
- Special keys like Enter, Spacebar, and Backspace
Keyboards can be wired or wireless, and they come in different styles for different needs.
History of the Keyboard
The history of the keyboard started long before computers. It began with a machine called the typewriter.
The keyboard has a long history that started with typewriters in the 19th century. Over time, it evolved into the modern computer keyboard we use today.
- 1868: Christopher Latham Sholes invented the typewriter, which introduced the QWERTY layout.
- 1870s: The QWERTY layout became standard for typing machines.
- 1930s–1940s: Electric typewriters were developed, making typing faster and smoother.
- 1960s: Computer keyboards were created, modeled after typewriters.
- 1980s: Personal computer keyboards became common, with function keys and arrow keys added.
- 1990s: Multimedia keyboards introduced with volume and shortcut buttons.
- 2000s–Present: Modern keyboards include wireless, ergonomic, mechanical, and touchscreen designs.
But guess what? Most of them still use the QWERTY layout from over 150 years ago.
How Does a Keyboard Work?
A keyboard works as a main input device that helps us type and control the computer. It changes our key presses into signals that the computer can understand.
When you press a key on the keyboard, a small signal is generated inside the device. This signal travels to the computer and tells it which key was pressed. The computer then shows the correct letter, number, or command on the screen.
Modern keyboards work mainly in two ways: mechanical switches and membrane pads. Mechanical ones give faster and accurate responses, while membrane ones are softer and cheaper. Both types make typing quick and smooth for everyday use.
Types of Keyboards
Not all keyboards are the same. Some are made for typing, some for gaming, and some for comfort. Keyboards come in many types, each designed for different needs. From simple typing to gaming and professional work, every type has its own special use.
Here are some types of keyboards.
- Mechanical Keyboard:
Mechanical keyboard uses individual switches under each key, which gives a clicky sound and strong feedback. Gamers and fast typists love it because of its accuracy and durability. It is long-lasting but usually more expensive. - Membrane Keyboard:
The membrane keyboard has soft keys that work by pressure pads instead of separate switches. It is cheaper, quieter, and lighter to use. However, it is less durable and not as fast as mechanical keyboards. - Wireless Keyboard:
A wireless keyboard connects to the computer using Bluetooth or a USB receiver, without any wires. It gives freedom to move and keeps the desk neat. But it needs batteries or charging to work. - Gaming Keyboard:
A gaming keyboard designed especially for gamers, it comes with RGB lights, extra keys, and fast response. It improves gaming performance and looks stylish. However, it is costlier than normal keyboards. - Virtual Keyboard:
A virtual keyboard is a software-based keyboard that appears on a touchscreen. It is used on smartphones, tablets, and touch-enabled computers. It saves space, but typing speed is slower compared to physical keyboards. - Ergonomic Keyboard:
An ergonomic keyboard is made in a special curved shape, it reduces strain on the hands and wrists. It is helpful for people who type for long hours. However, it takes time to get used to the design. - Flexible Keyboard:
A flexible keyboard is made of soft silicone material and can be rolled or folded. People use it for travel or in rough environments because it is waterproof and portable. But typing comfort is less than that of regular keyboards. - Projection Keyboard:
A projection keyboard is a modern type that uses a laser or light to project a keyboard on a flat surface. You can type by touching the projected keys. It looks cool and futuristic, but it is not very accurate for fast typing. - Multimedia Keyboard:
A multimedia keyboard has extra keys for controlling music, video, and internet functions. It is perfect for people who use computers for entertainment. The downside is that it costs more than a simple keyboard.
