Study Notes
Common Numeral Systems
- The most common numeral system is the decimal system, which is base-10 and uses digits from 0 to 9.
Uses of Numbers
- Beyond counting and measuring, numbers are used in data representation, coding, and cryptography.
- Numbers facilitate operations in computer science, finance, and statistics, serving as a fundamental element in algorithms and data analysis.
Basic Numerals Organization
- Basic numerals are organized into systems such as positional numeral systems, where the position of a digit affects its value.
- Examples include binary (base-2), octal (base-8), decimal (base-10), and hexadecimal (base-16).
Binary-Coded Decimal (BCD)
- BCD stands for Binary-Coded Decimal, a class of binary encodings for decimal numbers where each digit is represented by its own binary sequence.
Unpacked vs Packed BCD
- Unpacked BCD stores each digit of a decimal number in a separate byte, allowing for an easy read-and-write process.
- Packed BCD combines two decimal digits into a single byte to use memory efficiently and process data swiftly.
Term for BCD Digit States
- The ten states representing a BCD digit are commonly referred to as "nibble," which consists of four bits that can represent values from 0 to 9.
