ENIAC, in full Electronic Numerical Integrator and Computer, the first programmable general-purpose electronic digital computer, built during World War II by the United States. Under contract to the army and under the direction of Herman Goldstine, work began in early 1943 on ENIAC.
The standard computer keyboards typically contain 104 keys for inputting character sets including alphabets, numbers, symbols, or functions.
Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8-bits makes a byte.
The letter keys are in the centre of the keyboard. The symbol keys to the right of the letters include symbols such as the question mark and full stop. The keys that surround the letters, numbers and symbol keys on the left, right and bottom of the keyboard help you to choose where and how you type.
The space bar, also called the 'spacebar' or 'space key', is one of the most commonly used keys on a computer keyboard. It is used to put a space into something being typed. It is at the bottom of most standard keyboard layouts, such as the QWERTY keyboard.
