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.
