Study Notes
Ethics of IT
- Morality involves widely shared social conventions regarding right and wrong, forming a consensus.
- Virtue refers to habits promoting acceptable behavior, while vice promotes unacceptable behavior.
- Integrity entails following a personal set of principles and treating others with expected respect and consideration.
- Personal beliefs on right and wrong are termed morals, while ethics are the behavior standards expected by a group.
- Law comprises rules governing permissible actions, enforced by institutions like police and courts.
- Science involves systematic investigation of the natural world through observations and experiments, facilitating discovery and understanding.
Components of ICT
- Software includes operating systems and utilities enabling computer functions, consisting of instructions stored for execution by hardware.
- Application software performs tasks for users, while system software supports hardware and applications.
- The operating system coordinates system components to complete user tasks.
- Hardware consists of physical components like monitors, keyboards, and printers that can be physically interacted with.
- Telecommunications involves electronic information transmission over long distances.
- Databases store structured data, while data warehouses centralize data from multiple sources for deeper analysis.
History of Computers
- A computer is a programmable machine that stores, retrieves, and processes data.
- Significant historical tools include the abacus for calculations, Napier’s Bones for mathematical tasks, and the Pascaline limited to addition and subtraction.
- Important milestones include the ENIAC, the first electronic general-purpose computer, and the UNIVAC 1, the first business computer.
- The Osborne 1 marked the release of the first portable computer in 1981.
- Augusta Ada Byron is noted as the first computer programmer, suggesting Babbage use the binary system.
Generations of Computers
- First Generation: Large computers occupied entire rooms, using punched cards and printouts for input/output.
- Second Generation: Introduction of transistors made computers smaller, faster, and more reliable.
- Third Generation: Development of integrated circuits further miniaturized computers while reducing costs.
- Fourth Generation: Enhancements in graphical user interfaces (GUIs) and the introduction of the mouse as an input device were notable.
Parts of a Computer
- Processing Unit: The CPU, the computer's "brain," processes data and temporarily stores results in RAM.
- Input Devices: Equipment like keyboards and mice allow users to send information to the computer.
- Output Devices: Devices like monitors, printers, and speakers provide feedback to users.
- Storage Units: Includes floppy disks, hard disks, CD-ROMs, and memory sticks for permanent data storage.
Applications in Daily Life
- Business: Computers are essential for operational efficiency and management.
- Education: Facilitate learning through multimedia content and remote education.
- Arts and Entertainment: Integral tools in artistic creation and media production.
- Communication: Transform real-time global communication via platforms like Skype.
- Travel Planning: Aid in organizing travel arrangements including tickets and accommodations.
- Weather Forecasting: Utilize processing power for accurate meteorological predictions.
Principles of Networking
- Networking delivers messages from source to destination, with communication adding meaning to these messages.
- Network types include:
- Local Area Network (LAN): Short-distance connections, typically 10-100 Mbps, often owned by individuals or businesses.
- Metropolitan Area Network (MAN): Connects computers over specific geographical areas with slower speeds (5-10 Mbps).
- Wide Area Network (WAN): Covers large distances, connecting multiple LANs under distributed management; speeds of 256 Kbps-2 Mbps.
- Personal Area Network (PAN): Short-range networks for personal devices within 10 meters.
Computer Types
- Workstation: Powerful computer for tasks like CAD/CAM and software development requiring high-quality graphics.
- Desktop: A personal computer typically used on a table.
- Smartphone: A handheld device providing cellular and internet connectivity.
- Laptop: Portable computer suitable for various environments, allowing mobility and convenience.
