1.	What is binary number system? give it's uses
Answer» Hey mate here's your answer...Explanation:BINARY number system. A method of representing NUMBERS that has 2 as its base and uses only the digits 0 and 1. Each successive DIGIT represents a power of 2. For example, 10011 represents (1 X 24) + (0 X 23) + (0 X 22) + (1 X 21) + (1 X 20), or 16 + 0 + 0 + 2 + 1, or 19.Uses- Most modern computers use binary encoding for instructions and data. CDs, DVDs, and Blu-ray Discs represent sound and video digitally in binary form. Telephone calls are carried digitally on long-distance and MOBILE phone networks using pulse-code modulation, and on voice over IP networks.
