Study Notes
Computer Fundamentals Overview
- A computer is an advanced electronic device that takes raw data as input and processes it to produce output, while also storing results for future use.
- Main functions of a computer include input, processing, output, and storage.
Definitions
- Input: Raw information entered into a computer from input devices, such as letters, numbers, and images.
- Processing: Internal operation of the data based on given instructions.
- Output: Processed data generated by the computer, also known as results, which can be saved for later use.
Computer System Composition
- Computer System = Hardware + Software + User
- Hardware: Encompasses internal devices (like the CPU) and peripheral devices (like keyboards and mice).
- Software: Programs that provide functionality and intelligence to the hardware.
- User: The individual who operates the computer.
Major Parts of a Computer
- Input Devices:
- Mouse, keyboard, scanner, digital camera, web camera, joysticks, touchpad, light pen, graphics tablets, biometric devices, and barcode readers.
- Output Devices:
- Monitor, printer (dot matrix, inkjet, laser), projector, and speakers.
Central Processing Unit (CPU)
- The CPU is the core component of the computer that manages all operations, controlling internal and external devices, and executing arithmetic and logic functions.
Storage Devices
- Primary Memory:
- RAM (Random Access Memory) and ROM (Read-Only Memory).
- Secondary Memory:
- Hard disk, optical disks (CDs, DVDs), pen drives, zip drives, floppy disks, memory cards, and external hard disks.
Peripheral Devices
- Include modems, routers, internet adapters, and switches/hubs for connectivity.
Internal Components
- Motherboard, expansion slots, CMOS battery, and cooling fan.
Booting Process
- Warm Booting: Restarting the computer using reset button or key combination (CTRL + ALT + DEL).
- Starting Windows: Power on the supply, CPU, and monitor sequentially.
- Shutting Down: Close all applications, select shutdown from the Start menu, and follow prompts until it is safe to turn off all devices.
Basic Computer Literacy Quiz Insights
- Differentiate input, output, and dual function devices (like modems).
- Recognize required components for a functioning computer, emphasizing the importance of an operating system.
- Understand the CPU's role as the brain of the computer and different types of software.
- Familiarize with memory types: differentiate between temporary (RAM) and permanent (ROM) memory.
- Be aware of common terminologies like byte, megabyte, and the action of debugging a system.
Key Quiz Concepts
- Output Device Examples: Printer and monitor, not keyboard.
- Microprocessor Functions: Includes fetch, decode, execute, but not store.
- Networking: A system that connects individual computers is termed a network.
