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.
