Decimal Numbering System

Decimal Numbering System is the base-10 number system that we use daily. It consists of 10 digits from 0 to 9.

Binary Numbering System

Binary Numbering System is a base-2 number system. It uses only two digits: 0 and 1. Each digit represents a power of 2.

Unsigned Magnitude Representation

Unsigned Magnitude Representation is a method of representing positive integers. It uses the most significant bit to store the sign (0 for positive).

Sign-Magnitude Representation

Sign-Magnitude Representation is a method of representing both positive and negative integers. The most significant bit is used to store the sign (1 for negative, 0 for positive).

Two's Complement Representation

Two's Complement Representation is a method of representing both positive and negative integers. The most significant bit is used to determine the sign. Negative numbers are represented by inverting all bits of the positive equivalent and adding 1.

Two's Complement

A method used to represent negative numbers in binary, using 1's complement and adding 1 to the result. This allows for a consistent representation of both positive and negative numbers in a fixed-length system.

Binary Addition

Binary addition is performed just like decimal addition, but with the 'carry-over' to the next digit when the sum exceeds 1. Watch out for overflow, which occurs when the result exceeds the capacity of the system.

Carry Bit

The 'carry-over' bit is the result of the addition of two bits and a carry bit from the previous column. It propagates to the left column if the sum is 2.

Two's Complement Subtraction

Subtraction in Two's Complement is achieved by obtaining the two's complement of the subtrahend (number to be subtracted) and then adding it to the minuend (number being subtracted from).

Sign Bit

The most significant bit (MSB) in Two's Complement representation indicates the sign of the number. 0 represents a positive number, and 1 represents a negative number.

Overflow

Overflow occurs when the result of an arithmetic operation exceeds the maximum value that can be represented by a fixed-length system. In Two's Complement, overflow can be detected by the sign bit changing after the addition.
