Concept
A binary system is a system composed of two entities that interact with each other, commonly used in contexts like computing and astronomy. In computing, it refers to the base-2 numeral system used by digital devices, while in astronomy, it describes two celestial bodies orbiting a common center of mass.
Concept
Signed number representation is a method used in computing to encode positive and negative integers within binary systems. This representation allows computers to perform arithmetic operations on both positive and negative numbers efficiently, with common methods including sign-magnitude, one's complement, and two's complement.
Concept
The Bitwise NOT operation, also known as bitwise complement, is a unary operation that inverts all the bits of its operand, turning every 1 into a 0 and every 0 into a 1. This operation is crucial for performing low-level manipulations of data and is often used in applications involving binary arithmetic, data encoding, and digital circuit design.

Concept
Arithmetic overflow occurs when an arithmetic operation exceeds the maximum size that a data type can hold, leading to unexpected results or errors. This is a common issue in programming and computer systems, especially when dealing with fixed-size data types like integers.
Concept
Data encoding is the process of converting data into a specific format for efficient storage, transmission, and processing. It is essential for ensuring data integrity, compatibility across different systems, and optimizing data handling operations.
Concept
Negative binary numbers are typically represented using two's complement notation, which simplifies arithmetic operations and allows for a straightforward representation of both positive and negative integers. In this system, the leftmost bit is the sign bit, with '0' indicating a positive number and '1' indicating a negative number, and the negative value is derived by inverting all bits and adding one to the result.
Concept
The Bitwise NOT operation is a unary operation that inverts all the bits in a binary representation of a number, transforming 0s to 1s and 1s to 0s. It is often used in low-level programming to manipulate data at the bit level, providing a quick way to compute the one's complement of a number.
Signed integer representation allows computers to distinguish between positive and negative integers by reserving a bit to indicate the number's sign. The most common methods are signed magnitude, one's complement, and two's complement, with two's complement being the most widely used due to its ease of arithmetic operations.
