Keyboard And Speakers

            
             The keyboard is not just an accessory it is a necessity. If there weren't a keyboard it would be very difficult to use a computer. What is a Keyboard? "Keyboard, in computer science, a keypad device with buttons or keys that a user presses to enter data characters and commands into a computer. Keyboards emerged from the combination of typewriter and computer-terminal technology. They are one of the fundamental pieces of personal computer (PC) hardware, along with the central processing unit (CPU), the monitor or screen, and the mouse or other cursor device." A keyboard is an input device that gives information to the motherboard. The keyboard today is very similar to the first typewriter in 1873. Christopher Latham Sholes developed the first commercially successful typewriter. In 1873 the keys were arranged alphabetically. Quickly, people became adept to using the keyboard that the keys would jam when being struck quickly. To overcome this problem Sholes would try to make the job of typing as slow as possible. Sholes placed the most frequently used keys as far apart from each other as he could. His keyboard became known as the QWERTY keyboard.
             .
             In the 1930's a man by the name of August Dvorak put nine of the most used letters in the middle row of the keyboard. This allows the typist to write over 3,000 words without the fingers reaching. In comparison, only about 50 words can be typed on a keyboard without reaching on QWERTY's middle or home row. Dvorak's Keyboard is known as the Dvorak Keyboard.
             An even better keyboard than the Dvorak version was called the Malt keyboard, which was created by Lillian Malt. The Malt keyboard has staggered rows, gives greater use of the thumb and makes it easier to reach the backspace and other normally out of the way keys. Unlike the DVORAK keyboard! .
             There are many different styles of keyboards. There is even on the can fold up and fit in to your pocket. This style of keyboard would not be meant for a desktop PC but for a Palm Pilot.
