    Introduction to Computer Basics

    • Lesson Objectives:
      • Define a computer.
      • Describe the importance of computers in today's world.
      • Identify the main parts of a computer.
      • Identify the primary hardware components of a computer.

    The Role of Computers

    • Computers are essential tools in various sectors:
      • Business and industry
      • Publication field
      • Education field
      • Government organizations
      • Medical field
      • Science field
      • Entertainment field

    Parts of a Computer

    • Input Devices:

      • Devices that allow users to provide information to the computer.
      • Examples: Keyboard, Mouse, Microphone, Scanner, Webcam.

    • Output Devices:

      • Devices that display or present information processed by the computer.
      • Examples: Monitor, Printer, Speaker/Headphone.

    • Central Processing Unit (CPU) and Memory:

      • CPU: Interprets and executes commands given to the computer. Also known as the processor. Major brands include Intel and AMD.
      • Memory: Stores and retrieves information used by the CPU. Two types:
        • RAM (Random Access Memory): Main memory for temporary storage of commands and data.
        • ROM (Read Only Memory): Retains its contents even after the computer is turned off.

    • Motherboard:

      • Main circuit board inside the computer.
      • Contains electronic circuits and components.
      • Connects input, output, and processing devices (CPU, Memory, Hard Drive, DVD Drive).
      • Directs the CPU's operation.

    • Expansion Cards:

      • Video Card: Connects to the monitor, responsible for displaying information.
      • Network Interface Card (NIC): Enables communication between computers.
      • Sound Card: Converts audio signals (microphone or audio tape) into computer audio files.

    • Storage Devices:

      • Used for storing data permanently.
      • Examples: Hard Disk, Flash Drive, CD-ROM, DVD-ROM.

    • Ports and Connections:

      • Universal Serial Bus (USB) Port: Standard connection for various devices.
      • FireWire: Similar to USB, but faster.
      • Network Port (Ethernet): For connecting to a network.
      • Parallel Port and Serial Port: Older connection types.
      • Display Adapter: Connects to a monitor.
      • Power: Provides electrical supply.

    Using a Computer

    • Turning On: Press the power button on the system unit.
    • Log On: Access the operating system using a username and password.
    • Creating and Saving Files: Computers allow users to create, modify, and store files containing data.
    • Shutting Down: Click "Start" and select "Shut Down."

    Common Computer Terminology

    • Hardware: Physical components of a computer (keyboard, mouse, motherboard, monitor, hard disk, etc.).

    • Operating System: Most important software on the computer. Controls and manages the hardware. Provides an interface for interaction with the computer. Ensures proper functioning. Example: Windows XP.

    • Program/Application: Software that uses the hardware and operating system (platform) to perform tasks.

    • Data: Information processed by programs. Can be text, graphics, audio, or video.

    • Network: Group of computers and devices linked together. Facilitates information sharing, data sharing, and device sharing (printers). Components: Server, Workstation, Communication Channel.

    • LAN (Local Area Network): Connects devices within a limited area (home, small office).

    • WAN (Wide Area Network): Connects devices in geographically dispersed locations. Used to connect networks across countries. The internet is an example of a WAN.

    • Internet: Global collection of public networks connected for information exchange. Offers services like file transfers and email.

    • World Wide Web (WWW): Another internet service, also known as the Web.

    • Intranet: Similar to the Web but accessible only to authorized users within an organization.
