What is a Computer Keyboard?A computer keyboard is an input device that connects to your computer and sends signals between the present and the computer. Using a keyboard, a person can write a document, use keyboard shortcuts, access menus, and play and perform many other tasks. Keyboards can have different keys depending on the manufacturer, the operating system they are designed for and if they are attached to a desktop or a portion of a laptop. But for most, these keys, also called as keycaps, same size and shape from keyboard to keyboard. They are also located a similar distance from each other in a similar pattern.How Computer Keyboards Work?When you look the alternatives that are available for computer keyboards, it is difficult to believe that their original design came from mechanical typewriters that didn’t even need electricity. But no matter how many bells and whistles they offer, most keyboards operate using similar technology. They use switches and circuits to translate the keystrokes of a person in a signal that the computer can understand.

Layout:Computer keyboards are an input device. They place information that someone wrote a program on your computer. Most keyboards have between 80 and 110 keys. The numbers and letters on the keyboard displays the keys – these are the buttons that are pressed when a person types. The arrangement of numbers and letters are the same on all keyboards and called as QWERTY. Key matrix:

Inside, the keyboard is like a mini-computer and consists of the processor and circuits. These data can be transferred to the processor inside the computer. Inside, the processor in the array of live keyboard key. The fundamental matrix is a network of circuits. These circuits are individually set for each key. When the button is pressed, it pushes the switch to the circuit is the key causes an electric current through the circuit and the processor. When the current passes, the switch vibrates, signaling the processor to read.


The circuit is closed when you press a key. Closing the signal processing circuit to read the keymap stored there. The processor uses the coding scheme, sometimes called the Character Map to find the key that closes on the board. Using the map key, the processor can tell the keyboard what letter is pushing and if it should be a capital or lower depending on whether the shift key is pressed.

Communication:The keyboard connects to your computer for five pin male connector or PS / 2. Keyboards and computers work together to form a double sense. This means they can send data to each other. These two lines are parallel to the keyboard clock line and data line from the computer. Both lines will be used, or large, in order to send data to the keyboard. The computer sends a signal via the clock line of the keyboard through it you know that the line is clear to send. If the line is not clear, the keyboard to keep the data until the line opens. When the line is small, the keyboard from the computer waits for the command. When the computer wants to send data to the keyboard, brings the data line low and the clock. This means that the keyboard does not send the message at the same time.
