Study Notes
Data Representation in Computers
- The basic unit of data representation in computers is a bit.
- A bit stands for Binary Digit.
- A bit can convey 2 possible states (0 or 1).
Binary Number System
- The binary number system is the basis for the bit unit of data representation.
- In the binary number system, the existence of current in a computer bit represents a 1, and the absence of current represents a 0.
Bytes
- A single byte can represent a total of 2^8 (256) possible data combinations.
- A byte is a unit of data representation that consists of 8 bits.
Memory Units
- The unit used to express a computer memory of 524288 bytes is Kilobyte (KB).
- 1 Kilobyte (KB) is equal to 1024 bytes.
Word in Computer Context
- In the context of computers, the term 'word' refers to a unit of data that a computer processor can process in a single operation.
- The size of a word varies depending on the computer architecture.
Number Systems
- The symbols 0-9 are used for representation in the decimal number system.
Word Length and Computer Performance
- A computer with a larger word length is considered more powerful and faster because it can process more data at a time.
