binary

binary is a system that uses 1’s and 0’s to represent all types of data in computing, including numbers, letters, and symbols.

unsigned integers

A type of integer that can only represent positive whole numbers, with a range starting from 0 and extending to a maximum value based on the number of bits used for storage.

two’s compliment

A method for representing positive or negative numbers in binary, allowing for both positive and negative values. In this system, the most significant bit (the front one 128) signifies the sign of the number, with 0 for positive and 1 for negative.

binary addition

The process of adding binary numbers, following specific rules for carrying over when the sum exceeds the value that can be represented by a single bit.

(0+0 =0 , 1+0=1, 0+1=1 1+1=10, 1+1+1=11)

logical shifts

Logical shifts are binary operations used to shift the bits of a binary number either to the left then fill the rest of the slots with zeros

arithmetic shifts

Arithmetic shifts are binary operations that shift the bits of a binary number to the right then fill the rest of the slots with zeros

overflow

overflow occurs in binary addition where there is an extra digit in the start of the answer and errors might occur

hexadecimal
