Study Notes
Computer System
- A computer processes data and instructions to provide desired information.
- A computer system consists of elements that work together to process raw data.
Elements of a Computer System
- Data: Fundamental representation of facts; can be numeric, text, images, or sounds.
- Software: Consists of system and application programs controlling hardware functions; includes:
- System software (e.g., Operating System like Windows 10)
- Application software (e.g., web browsers like Google Chrome)
- Hardware: Physical devices that execute instructions and manage data transfer; includes:
- Microprocessor: Central component that processes data and instructions.
- Primary Storage: Temporary storage for active applications (e.g., RAM, cache memory).
- Secondary Storage: Long-term storage for files (e.g., HDD, SSD, Flash Drives).
- Input Devices: Tools for data entry (e.g., Keyboard, Mouse).
- Output Devices: Tools for data display (e.g., Monitor, Printer).
- Communication: Hardware and software that facilitate data transfer between systems (e.g., copper, fiber-optic, and wireless channels).
Architecture in Computer Systems
- Architecture refers to the design of components and the data flow within the system.
- Two design classifications:
- By Form: Refers to structure and size, including:
- Microcomputers: Designed for individual use (e.g., PCs, game consoles).
- Minicomputers: Support multiple users.
- By Form: Refers to structure and size, including:
Data Formats
- Data represented in bits (0s and 1s); machine-readable format.
- Input to computers via devices like keyboards or mice, converted to binary.
General Considerations for Data Processing
- File Type: Classifies types of files (e.g., audio, image, executable).
- File Format: Structure of files, including components like header and metadata.
- Metadata: Additional descriptive information about the file (e.g., JPEG dimensions).
- File Attributes: Permissions and settings related to file accessibility (e.g., read-only, hidden).
Classifications of Data
- Alphanumeric Characters: Data entered as symbols, letters, and numbers.
- Examples:
- ASCII: 7-bit standard for text.
- Unicode: Supports around a million characters across multiple encoding formats.
- Examples:
- Visual Data: Images categorized into bitmap and graphical objects.
- Formats include:
- GIF: Allows animation and stores images in 256 colors.
- PNG: Compression format supporting transparency.
- JPEG: Compression algorithm suitable for high-detail photographs.
- Formats include:
- Audio Data: Sound in digital form, requiring analog-to-digital conversion through sampling, quantization, and encoding processes.
