Study Notes

Introduction to Computing

Computers operate under the control of stored instructions, processing input data to produce output information.
Hardware encompasses the physical components of a computer system.

Green Computing

Focuses on reducing electricity consumption and waste generation through recycling, manufacturing regulation, product life extension, and donations.

Networking

A network connects multiple computers and devices, often wirelessly.
The Internet, originally known as ARPANET (1969), connects millions of businesses, governments, and individuals.

Software and Programming

Software instructs computers on tasks; programmers develop this software.
Peopleware emphasizes the human element in operating software and hardware systems.

Types of Computers

Personal computers manage all tasks independently (e.g., desktops, Apples).
Workstations are equipped with more powerful microprocessors.
Mini computers can support hundreds of simultaneous users.
Servers manage hardware/software access and provide storage.
Mainframes are powerful computers connecting thousands of users.
Supercomputers execute over one quadrillion instructions per second.
Embedded computers perform specific functions within larger systems (e.g., automobiles, home automation).

Game Consoles and Mobile Devices

Game consoles and mobile devices (handheld computers, tablets, smartphones) cater primarily to gaming.

Internet and Networking Concepts

Hotspots create wireless networks for device connections.
ISPs provide individuals with Internet access, generally for a fee.
Bandwidth measures network data transmission capacity.
IP addresses uniquely identify devices on a network; correspond to domain names via DNS.

Web and HTML

The World Wide Web (WWW) comprises electronic documents called webpages.
A website consists of multiple interconnected webpages, served by web servers.
HTML (Hypertext Markup Language) formats headings, text, images, and links in webpages.
Browsers allow users to access and view webpages.

Multimedia Elements

Multimedia combines text with graphics, animation, audio, video, and virtual reality elements.
Graphics represent non-text information through formats like BMP, JPEG, and PNG.
Infographics simplify complex concepts visually.
Animation creates motion through sequences of still images.
Virtual reality simulates environments in 3D space.

Email and Communication Tools

Email allows message and file transmission; email programs facilitate management of these messages.
Internet messaging enables notifications when contacts are online for real-time communication.
VoIP (Voice over Internet Protocol) allows voice conversations over the internet.
FTP (File Transfer Protocol) supports file uploading/downloading.

Computer Components

Input devices (e.g., webcams, mice) allow data entry.
Output devices (e.g., printers, monitors) convey information to users.
The system unit contains the CPU and RAM for data processing.
Storage devices (e.g., hard drives, flash drives) retain data for future use.
Communication devices (e.g., modems) facilitate data transmission between computers.

Internet Connectivity

Establishing internet presence involves planning, designing, creating, hosting, and maintaining online content.
