    Study Notes

    Introduction to Computing

    • This is a first-semester course covering various computer-related topics.

    Unit 3: Hardware

    • Hardware: The tangible, physical parts of a computer and related devices.
    • Main Computer Units:
      • Processor: Interprets and executes basic instructions to operate the computer. Has a Control Unit and Arithmetic & Logic (ALU) Unit. Registers: hold data & instructions; small, fast memory inside the processor
      • Control Unit: Manages the flow of data and instructions within the CPU; acts like a traffic controller.
      • Arithmetic and Logic Unit (ALU): Performs arithmetic and logical calculations inside the CPU.
    • Main Storage: (also called memory) stores data and instructions for processing.
      • RAM (Random Access Memory): Volatile - data is lost when power is off; stores data currently being used.
      • Cache Memory: High-speed memory for frequently accessed data.
      • ROM (Read-Only Memory): Non-volatile; stores instructions that the computer needs to operate (e.g. basic startup operations).
      • CMOS: Provides information whenever the computer turns on (e.g. RAM capacity, date/time)

    Unit 4: Peopleware

    • Peopleware: The people involved in computer and communication systems; crucial to the operation of computers.
    • Categories:
      • Business Analyst: Evaluates customer needs, creates business solutions
      • Business Systems Analyst: Solves information problems, analyzes requirements, and designs computer systems

    Unit 5: Software

    • Software: Programs with detailed instructions to tell the computer what to do.
      • System Software: Programs that handle or control operations of a computer.
        • Operating System (OS): Organizes and manages computer tasks; coordinates activities among devices; helps the user interact with the computer.
          • Functions: Helps with boot processes, provides user interface, manages programs and memory, schedules jobs, and more.
          • Types: Stand-alone OS (works on one device), network OS (work across a network)

    Internet and E-commerce Careers

    • This unit describes careers connected to the internet and eCommerce
    • Web Architect: Creates and implements interactive programs
    • Web Designer: Creates and designs websites
    • Web Programmer: Develops web-based programs
    • Web Administrator: Updates and maintains websites
    • Multimedia Designer: Manages graphic images, animation, and other multimedia elements

    Project Management

    • Project Manager: Defines the scope of the project, validates requirements, and plans deliverables.

    Systems Analysis and Design Career

    • Systems Analyst: Defines and analyzes computer system problems; also designs, implements and tests system standards and solutions.
      • Systems Architect: Develops computer hardware, software, and networking systems, maintaining and operating them to meet customer needs.

    Systems Management and Administration

    • Systems Administrator: Manages and maintains a network and its associated IT infrastructure (e.g. servers).
    • Network Administrator: Assists with network design, implementation, and support; maintains network equipment and connections

    Global Area Network (GAN)

    • GAN: Computers situated in different countries.

    World Wide Web

    • Internet: Collection of interconnected multimedia documents that can be accessed through a common protocol (HTTP).
    • Web site: Collection of web pages.
    • Web page: Electronic document on web site
    • Internet Concepts: Allows computers to connect and transmit data

    IP Addressing and Domain Names

    • IP Version 4 (IPv4): Four numbers separated by dots; represent a computer's location on the internet.
    • Domain Name: Text-based version of an IP address; uses DNS to translate domain names to IP addresses.

    Application Software

    • Application software: Programs for end-users including word processing, spreadsheets, databases, project management, accounting, and more.
