What is the decimal system? Ans: The number system with base 10 is called decimal system.

What is the binary system? Ans: The number system with base 2 is called binary system.

Write any two points of difference between the decimal and binary number systems. Decimal number system 1) The number system with base 10 is called decimal system. Binary number system 1)The number system with base 2 is called binary system. 2) In decimal number system each 2) In binary number system each of 10 digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. of 2 digits are 0, 1.

What is the place-value of each bit in the binary notation? Ans: In the binary notation, the place-value of each successive bit to the left of the unit position indicates a multiple of successive power of 2.

What is the byte? Ans: A group of 8 bit treated as a unit by computer hardware is called by a byte.

What is a word to a microprocessor? • Ans: The memory and cpu of a computer use a still larger unit called a word. The number of bits in a word can be 16, 32 or 64; this is , a computer may use a 2 byte , 4 byte or 8 byte word. Computer reads has a 64 bit processor with 4 GB RAM and 250 GB hard disk is saying that the microprocessor uses 64 bit word.

What is meant by ASCII code? Ans: ASCII code stands for American Standard Code for Information Interchange developed as a standard a table of 7 bit binary code to represent text.
