    Study Notes

    Computer Number Systems

    • Number systems are techniques for representing numbers in computer systems.
    • Decimal system: 10 digits (0-9). Base-10.
    • Binary system: Uses 0 and 1. Base-2.
    • Octal system: 8 digits (0-7). Base-8.
    • Hexadecimal system: 16 digits (0-9, A-F). Base-16.

    Data Processing

    • Raw data requires processing to be useful.
    • Data processing converts data into meaningful information.
    • Data processing occurs using analog or digital computers.

    Data vs Information

    • Data consists of raw materials such as letters, numbers, sounds, and images.
    • Information is processed data that has undergone operations and serves as input for further processing.

    Electronic Data Processing (EDP)

    • EDP uses computer or information and communications technology (ICT) equipment to process, operate, and manipulate data.

    Data Processing Cycle

    • Origination: Initially capturing raw data.
    • Input: Converting data into an acceptable processing format.
    • Processing: Electronic manipulation of data.
    • Output: Displaying results from data manipulation.
    • Storage and feedback: Storing processed data and evaluating results for future use or modifications.

    How Computers Communicate

    • Human language: English, Filipino, etc. A natural language used by people.
    • Binary language: 0s and 1s. The language understood by computers.
    • Machine language: Computer's language, e.g. assembly language.

    Computer Networks

    • A computer network interconnects two or more computers to share information and resources.
    • Personal Area Network (PAN): Limited connection usually within 10 meters.
    • Local Area Network (LAN): Connects computers within a common communication area (e.g., schools).
    • Wide Area Network (WAN): Networks across broader geographical areas (e.g., the internet).

    Methods of Communication (Wired)

    • USB: Universal Serial Bus for connecting peripherals.
    • FireWire: High-speed data transfer between devices.
    • Ethernet: Connecting to a network.
    • Parallel port: Older standard for connecting devices.
    • Serial: Older standard used for communication.
    • Audio: Used for input/output audio signals
    • VGA: Video standard used for computer graphics.
    • PS/2: Connecting keyboards and mice.

    Methods of Communication (Wireless)

    • Wireless communications include technologies such as microwave transmission, satellite communication, cellular transmission, and radio transmissions like Wi-Fi and Bluetooth.
    • Wi-Fi: Uses radio waves for wireless network connections.
    • Bluetooth: Connects devices wirelessly within a defined distance.

    Computer Software

    • Application Software: Programs for specific tasks.
    • System Software: Manages computer memory, instructions, and hardware.

    Types of Software interaction

    • Command-line operating systems: DOS is an example.
    • Graphical User Interfaces (GUI): Windows is an example.

    Computer Systems Platform

    • A platform is a combination of technologies (hardware and software) as a base.
