COMPUTER FUNDAMENTALS

Detailed explanation-1: -In computer science and mathematics, binary is a system where numbers and values are expressed 0 or 1. Binary is base-2, meaning that it only uses two digits or bits. For computers, 1 is true or “on", and 0 is false or “off". The concept of binary and bits are based on of Boolean Algebra.

Detailed explanation-2: -In every binary number, the first digit starting from the right side can equal 0 or 1. But if the second digit is 1, then it represents the number 2. If it is 0, then it is just 0. The third digit can equal 4 or 0.

Detailed explanation-3: -Rules and tricks: Binary subtraction is much easier than the decimal subtraction when you remember the following rules: 0 – 0 = 0. 0 – 1 = 1 ( with a borrow of 1) 1 – 0 = 1.

Detailed explanation-4: -binary code, code used in digital computers, based on a binary number system in which there are only two possible states, off and on, usually symbolized by 0 and 1.
