ICT Skills II Revision Notes

ICT skills are crucial for communication, business, and personal connections. Acquiring these skills keeps individuals updated with the latest software and applications.

Computer Hardware and Software

A computer system has two main components:
- Hardware: Physical parts like keyboards, monitors, and CPUs.
- Software: Non-physical components that direct hardware operations, such as Windows and MS Office.

Operating System

An operating system is an interface between the user and computer, controlling program execution and hardware operations.
Operating systems manage:
- Hardware supervision and status monitoring
- Device and software resource management
- Memory allocation (free and used)
- File and directory organization
- Disk space management

Types of Operating Systems

Single-user, single-task: Allows one user to perform one task at a time.
Single-user, multitasking: Allows one user to run multiple programs simultaneously. Examples include Windows and MacOS.
Multi-user: Enables multiple users to access and work on the same computer concurrently.
Real-time: Responds to tasks within specific time constraints.
Distributed: Runs on networked computers, seeming as a single integrated system. Windows, UNIX, and LINUX are examples.
Interactive (GUI-based): A user-friendly OS with graphical interfaces like Windows using mouse clicks, double clicks and right clicks.

Taskbar: The horizontal bar at the bottom of the screen, featuring Start button and access to open programs/files.
Start button: Accesses the Start menu for program and feature access.
Recycle Bin: A storage area for deleted files and folders that can be restored.

Creating and Managing Files and Folders

Files: Individual data units on a computer.
Folders/Directories: Organized groups of files for easy access.

Basic Shortcuts

Common keyboard shortcuts are included for various operations (e.g., Ctrl+Z for undo, Ctrl+S for save).
