Study Notes
Computer Model and Structure
- Computers operate on the Input-Process-Output (IPO) model, where data is input, processed, and outputted.
- Examples include adding numbers (e.g., 101 + 300 = 401) and printing documents (e.g., Test.docx printed as papers).
Components of a Computer System
- Three main components are hardware, software, and peopleware.
- Hardware includes input devices like keyboards and mice, output devices such as monitors and printers, and storage options like HDD and SSD.
- Software is categorized into system software, utility software, and application software.
Central Processing Unit (CPU)
- The CPU consists of the Control Unit (CU), Register, Cache, and Arithmetic Logic Unit (ALU).
- The CPU processes input data through the steps of decoding, executing, and producing output data.
- Main memory (RAM) temporarily stores data for quick access while executing programs.
Memory Hierarchy
- Cache Memory: Fastest but smallest memory, typically volatile (e.g., Static RAM).
- Main Memory: Larger, slower, often Dynamic RAM; available as DIMM and SO-DIMM.
- Secondary Storage: Non-volatile devices (HDD, SSD, flash drives) for permanent data storage, characterized by larger capacity but slower speeds.
Motherboard and Expansion
- The motherboard integrates various components and determines compatibility of hardware installations.
- Key features include CPU socket, RAM slots, and connections like SATA and expansion cards.
Expansion Cards
- Expansion cards enhance computer capabilities; types include Graphics Processing Units (GPUs) for better graphics handling and Network Interface Cards (NICs) for Internet connectivity.
Output Interfaces
- Different outputs are managed through connectors like VGA, DVI, HDMI, and Display Port, each having varying resolutions and capabilities.
Software Types
- Software is categorized into:
- System Software: Controls hardware operations and user interactions (e.g., operating systems like Windows, Linux).
- Utility Software: Provides system efficiency (e.g., antivirus programs, disk management).
- Application Software: Serves specific tasks (e.g., word processors, web browsers).
Operating Systems
- Different OS types serve various functions, including:
- Real-Time OS for time-sensitive tasks,
- Single User/Multitask OS for running multiple applications,
- Multi-User OS for concurrent use in environments like servers.
Utility Software
- Designed for system efficiency, encompassing security software (e.g., antivirus), disk management tools, and backup utilities.
Programming Languages
- Software is created using programming languages, which can be procedural, functional, or logical.
- Licensing includes proprietary software, free software, and open-source software (FOSS) like Linux.
Peopleware
- Refers to the users manipulating computers and software for personal and professional needs, covering activities from office productivity to programming.
