Study Notes

Computer Hardware and Software

  • Computer Components: A computer's physical parts (hardware) include the CPU (central processing unit), memory (RAM), storage devices (hard drive), input devices (keyboard, mouse), and output devices (monitor, printer). Buses connect these components.

  • Input Devices: Devices that provide data to the computer, like keyboards, mice, scanners, microphones, and touchscreens.

  • Output Devices: Devices that display information from the computer, such as monitors, printers, speakers, and headphones.

  • Storage Devices: Devices that store data persistently, including hard drives, SSDs (solid-state drives), and optical discs. RAM stores data temporarily while the computer is running.

  • System Software: Software that manages the computer system, including the operating system (e.g., Windows, macOS, Linux). System software also includes utilities for file management, system maintenance, and device drivers.

  • Application Software: Software designed for specific tasks, like word processing, web browsing, and games.

Computer Networks

  • Types of Networks: Networks can be categorized by their size and geographic reach (LAN - local area network, WAN - wide area network). Peer-to-peer networks connect devices directly to each other, while client-server networks have specialized servers.

  • Network Communication: Networks use various protocols (such as TCP/IP) to facilitate communication between devices.

  • Communication Methods: Networks use various media, including wired connections (like Ethernet cables), and wireless connections (like Wi-Fi).

Number Systems

  • Decimal System: Uses digits 0-9.

  • Binary System: Uses only 0 and 1.

  • Octal System: Uses digits 0-7.

  • Hexadecimal System: Uses digits 0-9 and letters A-F.

Computer Generations

  • First Generation: Used vacuum tubes.

  • Second Generation: Used transistors.

  • Third Generation: Used integrated circuits.

  • Fourth Generation: Used microprocessors.

  • Fifth Generation: Focuses on artificial intelligence and more complex processing.

Computer Software

  • Types of Software: Includes system software (like operating systems and utilities) and application software (like word processors, web browsers, and games).

  • Malware: Malicious software, such as viruses, spyware, and worms, infecting a computer.

E-learning

  • Interactive Tools: Tools such as electronic whiteboards, email, and communication platforms support collaborative learning and interaction.

  • Learning Management Systems: Online platforms facilitating learning, content management, and community building.

Other Concepts

  • Processor Speed: Measured in Hertz (Hz), indicating the processing cycles per second.

  • RAM (Random Access Memory): Temporary storage used during computer operation.

  • ROM (Read-Only Memory): Stores permanent instructions needed for boot-up.

  • CPU (Central Processing Unit): The main component responsible for executing instructions.

  • Input/Output Units: Devices that facilitate data transfer to and from the computer.

  • Hardware: The physical components of a computer.

  • Software: The programs that run on a computer.
