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.
