Data Representation in Computers Session 3 Data Representation in Computers/Session 3 / 1 of 45 .Session Objectives s s s s s Describe what a Number system is Explain the decimal, octal and hexadecimal number systems Convert a number from one | Data Representation in Computers Session 3 Session Objectives Describe what a Number system is Explain the decimal, octal and hexadecimal number systems Convert a number from one number system to another Practice binary arithmetic List the various standard codes used to represent the unit of information ASCII EBCDIC Session Objectives (Contd.) Explain Data Representation Explain Data Storage Explain Packed Decimal Binary Arithmetic Calculation Explain CPU and its speed Number systems The additive approach - Number earlier consisted of symbols . Roman number system - I for 1, II for 2, III for 3 etc. Positional numbering - Symbols represent different values depending on the position they occupy . the Decimal system Decimal Number System In the decimal number system the successive position to the left of the decimal point represent units, tens, hundreds, thousands etc. (3 * 100) + (6*10) + (5*1) = 365 The position of the number affects its value. These kind of number systems therefore are called positional number system. Base Position number (6*10) Decimal Number System (Contd.) The value of each digit in the number system is determined by: a) The digit itself b) The position of the digit in the number c) The base/radix of the system Binary Number System The binary number system has a base of two and symbols used are 0 and 1. In this number system, as we move to the left, the value of the digit will be two times greater than its predecessor because the base is two. Thus the value of the places are : 64 32 16 8 4 2 1 0001111001010111 Least Significant bit Most Significant bit Binary Number Octal number systems Binary Octal 000 0 001 1 010 2 011 3 100 4 101 5 110 6 111 7 Uses a base of 8 Values increase from right to left 1, 8, 64, 512 . Octal Number System The octal system has the base of 8. The value increase from right to left as 1, 8, 64, 512, 4096. The decimal value of an octal number 1204 can be computed as : 1204 = (1 * 512) + (2 * 64) +
