How are data being represented in computers? Computers work with a binary number system that consists of only two digits - zero and one. Inside the computer binary number is represented by an electrical pulse. One means a pulse of electricity and zero means no pulse. All the data entered into computers is first converted into the binary number system. One digit in binary number system is called bit and combination of eight bits is called byte. A byte is the basic unit that is used to represent the

The pulses produced by the rotating disk must be counted over a known period of time‚ and the table or equation used to convert the binary count to miles per hour. 1-2. –34° quantizes to –30° => 1 V => 0001 +31° quantizes to +30° => 7 V => 0111 +77° quantizes to +80° => 12 V => 1100 +108° quantizes to +110° => 15 V => 1111 1-3.* Decimal‚ Binary‚ Octal and Hexadecimal Numbers from (16)10 to (31)10 Dec Bin Oct Hex 1-4. 16 17 18 19 20 21 22 23 24 25 26 27 28 29

CHAPTER 2 BINARY CODE 2.1 History of Binary Code: Binary numbers were first described in Chandashutram written by Pingala around 300 B.C. Binary Code was first introduced by the English mathematician and philosopher Eugene Paul Curtis during the 17th century. Curtis was trying to find a system that converts logic’s verbal statements into a pure mathematical one. After his ideas were ignored‚ he came across a classic Chinese text called I Ching or Book of Changes‚ which used a type of binary code. The

widely used by modern civilizations. Modern computer hardware and software systems commonly use a binary representation internally (although many early computers‚ such as the ENIAC or the IBM 650‚ used decimal representation internally). For external use by computer specialists‚ this binary representation is sometimes presented in the related octal or hexadecimal systems. For most purposes‚ however‚ binary values are converted to or from the equivalent decimal values for presentation to or input from

the computer’s language is binary 0s and 1s. The computer cannot understand typed or written instructions or data. Whenever data or instructions or input to the computer it is first converted to 0s and 1s‚ these are called binary digits (bits). There are a number of methods that are used to represent data in computer system‚ namely: 1. Binary Representation 2. ASCII - American Standard Code for Information Interchange 3. EDCDIC - Extended Binary Coded Decimal Interchange
