Study Notes
Computer Foundations Overview
- Chapter covers fundamental aspects of computer operations and serves as a primer for data storage concepts.
- Focus on topics such as data organization, number formats, boot processes, and disk geometries.
Data Organization
- Digital data processing relies on understanding data structures and organization on disk.
- Key concepts include binary and hexadecimal numbers, data sizes, and endian ordering (little and big-endian).
Number Formats
- Decimal system uses ten symbols (0-9), while binary system uses two symbols (0, 1).
- A bit is the basic unit in binary, organized into groups of 8 called bytes.
- Decimal numerals are calculated based on positional values multiplied by column values (powers of 10).
Binary Numbers
- Binary system columns double in value: right-most column is 1, second column is 2, third is 4, fourth is 8, etc.
- Conversion from binary to decimal involves multiplying each bit by its positional value and summing the results.
- Example: Binary number 1001 0011 converts to decimal 147.
Hexadecimal Numbers
- Hexadecimal (base 16) uses 16 symbols (0-9 and A-F) for representation.
- Facilitates easier conversion from binary due to its compact format; each hex digit corresponds to a 4-bit binary group.
- Example conversion table provides binary, decimal, and hexadecimal values for the first 16 numbers to aid understanding.
Endian Ordering
- Little-endian stores the least significant byte first, while big-endian stores the most significant byte first.
- Understanding endian ordering is critical for data interpretation and transmission across different computing architectures.
Boot Process
- Initial code execution during a boot process prepares the computer's operating system for use.
- Involves reading necessary information from hard disks and initializing hardware components.
Hard Disk Organization
- Hard disks contain geometrical structures (tracks and sectors) crucial for data storage and retrieval.
- Understanding ATA commands and host protected areas is important for interacting with hard drives and managing data effectively.
- SCSI (Small Computer System Interface) protocols are also essential for connecting and communicating with peripheral devices.
