Frequently Asked Questions
Q.What is Hexadecimal?
Hexadecimal (Base 16) is a number system that uses 16 distinct symbols: 0-9 to represent values zero to nine, and A-F to represent values ten to fifteen.
Q.Why do computers use Binary?
Computers use binary because their hardware is based on transistors, which have two distinct states: on (conducting current) and off (not conducting), representing 1 and 0.
Q.How do I convert Binary to Decimal?
Multiply each bit by 2 raised to the power of its position (starting from 0 on the right) and sum the results.
