Study Notes
Data Representation
- Data representation in computers uses various systems including base 10 (decimal), base 2 (binary), and base 16 (hexadecimal).
- Humans are accustomed to base 10, using 10 digits (0-9).
- Binary (base 2) uses 2 digits (0 and 1).
- Hexadecimal (base 16) uses 16 digits (0-9 and A-F).
Binary and Prefixes
- In computing, a binary system is used. This system has only two digits, 0 and 1, and is often used to represent information and data.
- Binary numbers are represented by a series of 0s and 1s.
- Prefixes in binary systems denote magnitudes similarly to decimal systems, like kilobytes (KB), megabytes (MB), etc.
- The fundamental unit is a bit.
- 8 bits form a byte.
Hexadecimal
- The hexadecimal system uses base 16.
- It uses digits 0-9 and letters A-F.
- A conversion method from hexadecimal to decimal exists. The method involves multiplications by relevant powers of 16.
Binary Coded Decimal (BCD)
- BCD uses a 4-bit system to represent each digit in a decimal number.
- Each decimal digit is represented by a separate 4-bit code.
- This is useful for displaying decimal digits individually (like on a digital clock).
ASCII & Unicode
- ASCII (American Standard Code for Information Interchange) uses numerical codes to represent characters.
- It has 127 characters and symbols.
- Unicode is a larger system for encoding characters; it supports a wider range of characters. It includes representations for symbols from widely different languages and cultures.
