What is Computer Keyboard ?

The standard layout of letters, numbers, and punctuation is known as QWERTY because the first six typing keys on the top row of letters spell QWERTY

But how is that possible? Instead of typing one character with one key (like on the normal keyboard), in chorded keyboard you're using chords (like on the piano).

The QWERTY keyboard was designed in the 1800s for mechanical typewriters and was actually designed to slow typists down to avoid jamming the keys on mechanical units.

This way you can type much more characters than there's physical keys. Chorded keyboards are used mainly by visually impaired (Braille versions) and in situations where normal keyboard is useless.

AZERTY is the French version of the standard QWERTY layout. AZERTY keyboards differ slightly from the QWERTY keyboard. For example, the Q and W keys have been interchanged with the A and Z keys.

Do you know that your keyboard may contain more germs than toilet seat?

Another well-known design is the Dvorak, which has letters positioned for speed typing. Unlike the traditional QWERTY, the Dvorak is designed so that the middle row of keys includes the most commonly used letters in the alphabet.

The three differ somewhat in the placement of function keys, the Control key, the Return key, and the Shift keys. In addition to these keys, PC keyboards usually contain the following keys: Page Up, Page Down, Home, End, Insert, Pause, Num Lock, Scroll Lock, Break, Caps Lock, Print Screen.

A study conducted by UK scientists found out that four out of 33 keyboards tested were potential health hazards, and one had levels of germs five times higher than that found on the toilet seat.

There are several different types of keyboards for the Apple Macintosh. All are called ADB keyboards because they connect to the Apple Desktop bus (ADB). The two main varieties for Macintosh are the standard and extended, which features 15 additional special-function keys.

Some keyboards in office buildings even had mice droppings in them! How to prevent this situation? Wash your hands and clean keyboard the right way.

Space Cadet keyboard was designed by Tom Knight for the MIT Lisp machines back in the 70's. It looks like taken straight from Star Trek.

Keeping with the times and the popularity of smartphones, tablets and other small devices, gesture-based keyboards are often the most popular choice for mobile computing devices. A new layout, called KALQ has been designed by researchers from Max Planck Institute of Informatics, Montana Tech and University of St.Andrews. KALQ is optimized for rapid two thumb typing on touchscreen devices.

Capacitive: Uses changes in capacitance to register when a user has depressed a key.
Chiclet: Features elevated keys that have some space between them in a design that is rectangular in shape with rounded edges.

The keyboard is known for it's elongated look and abundance of modifier keys, with names such as Super, Meta, Terminal, Status and Hyper.

Name "Space Cadet" came from a title of 1948 science-fiction novel by Robert A. Heinlein. Now you can have stylized version of this keyboard on your MacBook, using these keyboard decals.

Gaming: Features additional programmable keys, macro functions or digital displays for use in computer games. They are usually backlit and are more robust: mechanical switches and laser-etched keys for durability.

Multimedia: A computer keyboard that contains additional keys and buttons for media options such as volume, brightness and video controls.
On-Screen: An application which provides a visual keyboard on your display screen that can be used in place of a physical keyboard.

Virtual keyboard: A full-size image of a QWERTY keyboard is projected onto any surface.
Wedge: Hardware or software that interfaces with a computer to translate data read by a device other than a keyboard, such as a magnetic strip or bar code reader.

There is an ongoing trend for the last couple of years, especially among young people, to decorate their laptop keyboards (and whole laptops) with vinyl stickers.

A computer keyboard is an input device that allows a person to enter letters, numbers, and other symbols (these are called characters) into a computer. It is one of the most used input devices for computers. Using a keyboard to enter lots of data is called typing.

These stickers are subject to fashion, have trending colors or patterns, like Stardust or Washi tape.

keyboard contains many mechanical switches or push-buttons called "keys". When one of these are pushed, an electrical circuit is closed, and the keyboard sends a signal to the computer that tells it what letter, number or symbol it would like to be shown on the screen.
