Study Notes
Computer Number System
- A number system is a technique used to represent numbers.
- Number systems are used in various applications, including to calculate the number of people in a movie hall or queue.
- The base or radix of a number system is the total number of digits available in that system.
- Number systems are crucial for converting numbers for technical computing purposes.
- Computer architecture relies heavily on various number systems (binary, octal, hexadecimal).
Types of Number Systems
- Decimal: A base-10 system using digits 0-9
- Binary: A base-2 system using digits 0 and 1, the most fundamental system in computer science
- Octal: A base-8 system using digits 0-7, commonly used in computer programming and digital electronics.
- Hexadecimal: A base-16 system using digits 0-9 and A-F (A = 10, B = 11, C = 12, D = 13, E = 14, F = 15), frequently used in computers to reduce the size of binary representation.
Conversion Steps of Number Systems
- Understanding the current number system's digits and their values
- Binary system uses powers of 2 starting from 2⁰
- Octal uses powers of 8.
- Hexadecimal uses powers of 16.
- To convert a decimal number to binary, keep dividing by 2 until you reach 0; remainders form the binary equivalent. (Least significant digit is the last remainder, the most significant digit is the first remainder).
