Study Notes

CPU (Central Processing Unit)

The CPU is the brain of a computer, handling calculations and executing instructions.

RAM (Random Access Memory)

RAM is volatile memory that stores data while the computer is on.
More RAM means the computer can process more data simultaneously, leading to better performance.
RAM is essential for multitasking, allowing multiple applications to work without slowing down the computer.

Storage Devices

Storage devices store data permanently or temporarily.
Hard Disk Drives (HDD): Use spinning disks for data storage, offering large capacity at lower cost.
Solid State Drives (SSD): Use flash memory for faster data storage than HDDs, offering durability and quicker access.
Cloud Storage: Data stored on remote servers, accessible via the internet. Examples include Google Drive, Dropbox, and OneDrive.

Input/Output (I/O) Devices

Input Devices: Allow users to interact with the computer. Examples include keyboard, mouse, optical pen, joystick, scanners, and bar code readers.
Output Devices: Allow the computer to communicate information to the user. Examples include monitors, headphones, speakers, laser printers, faxes, projectors, and plotters.

System Software

System software acts as the intermediary between hardware and the user
Operating system (OS) is essential system software responsible for resource allocation
Popular OS examples include Windows, macOS, Linux, and Android
OS manages crucial hardware and software resources like memory, processor, and storage
Device drivers enable communication between the OS and peripheral devices
Utilities are software tools for managing, maintaining, and controlling computer resources, including antivirus software, disk cleaners, and backup tools

Application Software

Application software focuses on specific tasks, allowing users to accomplish specific jobs
Examples of common application software include:
- Word processors like Microsoft Word enable document creation and editing
- Web browsers like Google Chrome and Mozilla Firefox facilitate internet browsing and access
- Multimedia software like Adobe Photoshop allows image, video, and audio manipulation

LAN (Local Area Network) vs. WAN (Wide Area Network)

A LAN (Local Area Network) covers a small geographic area, like a home or office.
LANs connect computers and devices within this area to share resources such as files and printers.
A WAN (Wide Area Network) covers a large geographic area, such as a city, country, or even globally.
The internet is the largest WAN, connecting millions of networks worldwide.

How the Internet Works

The internet is a global network of interconnected computers and devices.
Data centers are facilities that house servers which store and process data.
Data is transmitted across the internet using physical cables, such as fiber optics, and satellites.
Data is transmitted across the internet in packets - small units of data that travel from the sender to the receiver via multiple routes.

Overview of Microsoft Word

Microsoft Word is a word processing software used for creating, editing, and formatting text documents.
The software offers a user-friendly interface with a ribbon at the top containing tabs like Home, Insert, and Layout, each with groups of related commands.
The document area serves as the main workspace for typing and editing text, where the cursor indicates the insertion point for new text.

Basic Tools in Word

Basic tools for text formatting include changing the font, size, color, and style (bold, italics, underline).
Word's spell check feature automatically detects spelling and grammar errors and recommends corrections.
The software includes page layout tools for adjusting margins, document orientation, and size.

Creating and Saving a Document

To create a new document in Word, open the software, select "New" from the File menu or click "Blank Document," and begin typing in the document area.
Regularly saving your work is crucial.
To save a document, click "File," select "Save As," choose a location on your computer, give the document a name, and click "Save."

Basic Text Formatting

Basic text formatting enhances the visual appeal of a document.
Common formatting options include adjusting font details like type, size, color, and applying styles like bold, italics, and underlining.

Word Processing Features

Font selection allows users to choose from a variety of fonts, altering the appearance of text.
Size adjustment modifies font size, making text larger or smaller.
Bold, italics, and underline are formatting options used to emphasize text.
Alignment features organize text by adjusting its horizontal position (left, center, right, or justified).
