What is a Computer Keyboard?
A computer keyboard or keyboard is an Input device just like a typewriter that uses buttons that act as mechanical levers or electronic switches to permit you to type text on your computer. Every button on the keyboard performs a definite task and is committed to typing a specific letter.
Typically, these letters or tasks are recorded on the button. Of course, while writing some special characters, it requires pressing two buttons at the same time. Most of your computer keyboard buttons belong to a letter, symbol, or number, and a limited number of buttons are designed to perform a specific function.
History Of Keyboard
For the first time, humans start to type letters and words mechanically with the help of a typewriter. As time passes on, punch cards and paper strips became less popular, a new technology for typing a variety of texts, known as the Teleprinter, emerged.
Teleprinters were used in the early 1870s as an instrument for simultaneous typing and data transfer in the stock market. In 1907, two American engineers, Charles and Howard Chrome, and an electrical engineer, Frank Pierre, worked on a more advanced model of Teleprint, which led to the modern form of the keyboard.
A tool that led to the invention of keyboards that worked with the help of buttons and the Teleprinter system. Herman Hollerith was the person who introduced the first computer keyboard to the world of technology.
Function of Keyboard
The most common applications of a computer keyboard are as follows:
- Write Text: Keyboards have a range of uses. But the first and primary use of a computer keyboard is to act as an interface for transferring letters, symbols, and numbers to word processing software. In a simpler definition, the first use of keyboards is to write various texts on a computer.
- Function Commands: Another use for the keyboard is to deliver some function commands to the computer via the keys. For example, using the Ctrl + alt + delete key combination in Windows is responsible for opening the Task Manager window.
In fact, the keyboard in this example becomes the command line interface of your computer. With this feature, you can navigate Windows and do some simple tasks without using a mouse, such as opening a file or deleting it. Of course, the keyboard does not end here, and the most interesting actions are performed with this tool,
- Play Games: it can be used to run a game. Those who are interested in computer games are well familiar with the function of the computer keyboard in this field. Keyboards become one of the most important tools for players to move while playing, making it easier for players to find the way and control the game space.
Types Of Keyboard
Computer keyboards, in general, are made for human-computer interaction. There are different models of keyboards depending on their size, appearance, and application. Each of these models is specifically designed for the user and meets the needs of a specific group of users.

Structure of Keyboards
Keyboards, while simple, has an interesting complexity. In fact, if we look closely at their construction, we recognize that keyboards are a kind of computer in themselves. If you take out the keys on the keyboards, you will perhaps come across a hole or a dome-shaped plastic object that will not give you very accurate information about what is going on in the heart of your keyboard.
However, the view in front of you is a window with a much more complex structure that is secreted inside the body of your keyboard. If you take away the bottom cover of the keyboard with a clear plastic plate, You will find that it shows you how the buttons work.
Inside this plastic enclosure are circuits on which the precise location of each switch is marked. These locations are marked by layers of plastic that can sense the pressure on the buttons. If you look closely, you can see bars between the layers pushing the button down from the top.
In addition, a number of LED lights are placed side by side to show the user the status of keys such as “NUM LOCK” on or off. In this case, you can even observe the location of the connection cable to the computer, which is accountable for transmitting energy signals between the computer and the keyboard.
How did Keyboard Work?
As we said, there is a spring or plastic object below each button of the keyboard that works like a spring and returns it to its initial state when the key is pressed. But this is not just the work of springs or plastics.
Below the buttons, there are three separate layers of plastic, two of which are the circuits of your keyboard, which can sense the compression of each button. The third layer is located between the two electrical layers and acts as an insulator.
These circuits are typically designed in such a way that they are completed when the button is lowered and electricity flows through them. When you press any of the keys on your keyboard, by completing the circuit diagram and moving a light current in them, you transmit the signals linked with that particular button to your computer.
Can We Connect the Keyboards to Our Smartphone?
Based on the type of keyboards, the keyboard can be connected to a computer or laptop wirelessly or using USB.
