Number System

The hexadecimal number system, also known as base-16, is a positional numeral system that uses sixteen distinct symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. The letters A to F represent decimal values 10 to 15, respectively. Each position in a hexadecimal number represents a power of 16, starting from $16^0$ at the rightmost digit. For example, the hexadecimal number 2F3 equals $2 \times 16^2 + 15 \times 16^1 + 3 \times 16^0 = 512 + 240 + 3 = 755$ in decimal. Hexadecimal is widely used in computing and digital electronics because it provides a compact way to represent binary numbers, where each hex digit corresponds exactly to four binary digits. This makes conversion between binary and hexadecimal simple and efficient. Hexadecimal is commonly used in memory addressing, color coding in web design, and programming to simplify representation of large binary values. Understanding hexadecimal is essential for computer scientists, programmers, and engineers, as it bridges the gap between human-readable numbers and machine-level binary code, facilitating efficient computation, debugging, and data interpretation.

Number System

The base-2 number system, commonly called the binary system, is a positional numeral system that uses only two digits: 0 and 1. Each digit, known as a bit, represents a power of 2, with the rightmost position representing $2^0$, the next $2^1$, and so on. For example, the binary number 1101 equals $1 \times 2^3 + 1 \times 2^2 + 0 \times 2^1 + 1 \times 2^0 = 8 + 4 + 0 + 1 = 13$ in decimal. Binary is fundamental to computing and digital electronics because electronic devices operate in two states: on and off, represented by 1 and 0. This simplicity allows computers to store, process, and transmit data reliably. Binary numbers are used in memory storage, processor instructions, networking, logic circuits, and coding systems. Understanding base-2 is crucial for computer science, programming, and engineering because it explains how machines represent and manipulate information. Binary arithmetic, logic operations, and data encoding form the foundation for higher-level computations, making the base-2 system indispensable for modern technology, digital communications, and computing systems.
