Study Notes

### Introduction to Computer Basics

Computers are essential in today's world, impacting various fields such as business, education, healthcare, and entertainment.

Parts of a Computer

Input Devices: allow users to interact with the computer. Examples include keyboards, mice, microphones, scanners, and webcams.
Output Devices: display information processed by the computer. Examples include monitors, printers, and speakers/headphones.
Central Processing Unit (CPU): Interprets and executes commands given to the computer, also referred to as the processor. Major brands include Intel and AMD.
Memory: Stores information that can be accessed by the CPU. There are two main types:
- RAM (Random Access Memory): Used for temporary storage of commands and data.
- ROM (Read Only Memory): Retains information even when the computer is turned off.
Motherboard: Main circuit board within the computer that connects various components like the CPU, memory, hard drive, and DVD drive. It also instructs the CPU on how to run.
Expansion Cards: Extend the functionality of the computer. Examples include:
- Video Card: Connected to the monitor for displaying information.
- Network Interface Card (NIC): Connects the computer to a network for information exchange.
- Sound Card: Conerts audio signals into computer audio files.
Storage Devices: Store data and programs. Examples include:
- Hard Disk: Primary storage location for the operating system and applications.
- Flash Drive: Portable storage device.
- CD-ROM and DVD-ROM: Optical storage devices.
Ports and Connections: Provide interfaces for connecting various devices to the computer. Examples include:
- USB (Universal Serial Bus) Port: Versatile port used for connecting various peripherals.
- FireWire: Similar to USB but offers faster data transfer speeds.
- Network Port (Ethernet): Connects the computer to a wired network.
- Parallel Port and Serial Port: Older ports used for connecting printers and other legacy devices.
- Display Adapter: Connects the computer to a monitor.
- Power: Supplies electricity to the computer.

Using a Computer

To power on a computer, press the power button on the system unit.
Login to the operating system using a user name and password.
Computers allow users to create, modify, and save files.
To shut down a computer, click Start and select Shut Down.

### Common Computer Terminology

Hardware: Refers to all the physical components of a computer, such as input devices, processing devices, storage devices, and output devices.
Software: Programs that provide instructions for the computer to perform specific tasks.
Peripherals: Devices that are connected to a computer and provide additional functionality.
Operating System (OS): The most important software that controls and manages all the hardware connected to a computer.
- Provides a user interface for interacting with the computer.
- Ensures the proper functioning of the computer.
- Ex: Windows XP.
Program (Application): Software designed to perform specific tasks. Examples include word processors, spreadsheets, and web browsers.
Data: Information processed by the computer. It can be in various forms, including text, graphics, audio, and video.
Network: A group of computers and devices linked together to facilitate sharing information and resources. Types of networks include:
- LAN (Local Area Network): Connects devices within a limited area, such as a home or a small office.
- WAN (Wide Area Network): Connects devices over a wide geographical area.
Internet: A worldwide collection of public networks connected for information exchange.
- Offers various services, including file sharing and email.
- The World Wide Web (WWW), or the Web, is a service provided by the Internet for browsing and accessing information.
Intranet: A private network within an organization, similar to the Web, but only accessible to authorized users.
