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.
