Prerequisites:What is decimal number system? Decimal number system is used in our general counting. In decimal number system there are ten digits which are used to form decimal numbers. Ten separate symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 http://improvec.blogspot.in/ 3
Number systems: Number systems are useful in digital computer technology. To perform arithmetic operations. http://improvec.blogspot.in/ 4
Number systems (contd): A programmer who works on a computer is allowed to use decimal digits http://improvec.blogspot.in/ 5
Number systems (contd): Number systems are useful in designing the digital systems. To understand the operation of a computer the knowledge of binary, octal and hexadecimal number is essential. http://improvec.blogspot.in/ 6
Why computers use binary number systems? In all modern computers, storage and processing units are made by electronic components which can only indicate two states i.e. 0(off) or 1(on). So binary number system is conveniently used to express the two possible states. http://improvec.blogspot.in/ 7
Why computers use binary number systems? (contd) We can easily design a computer circuit to process data with binary digits. It reduces the cost and improves the reliability. Everything that can be done with decimal system can also be done in binary system. http://improvec.blogspot.in/ 8
