Fundamental Concepts in Computer Science

Fundamental Concepts in Computer Science (Diploma in Office Management)

Computer Systems: A computer system is a collection of interconnected components that work together to perform tasks.
- Hardware: Physical components of a computer, such as the motherboard, CPU, RAM, storage devices (hard drive, SSD), input devices (keyboard, mouse), and output devices (monitor, printer).
  - Different types of storage with their capacity and speed
  - Understanding the role of each component in the system's operation
- Software: Instructions that tell the hardware what to do; examples are operating systems (like Windows, macOS, Linux), applications (like word processors, spreadsheets, browsers), and programming languages (like Python, Java).
  - Distinction between system software and application software
  - Describe different types of software packages
  - Importance of software in operating computer systems
Input/Output Devices: Devices that enable communication between the user and the computer.
- Examples include keyboards, mice, scanners, microphones, touchscreens, printers, monitors, speakers, etc.
  - Explain the functions of different input devices
  - Explain the functions of different output devices
  - Types of input and output methods
Data Representation:
- How computers represent information using binary code (0s and 1s).
  - Number representation (decimal, binary, hexadecimal)
  - Character encoding (ASCII, Unicode)
- How data is stored and retrieved from different storage devices.
  - Discuss the difference between RAM and ROM
Storage Devices:
- Hard drives, SSDs, USB flash drives.
  - Storage capacity (e.g., gigabytes, terabytes)
  - Data retrieval speeds (e.g., read/write speeds)
  - Describe various types of external storage devices.
Operating Systems: Software that manages computer hardware and software resources; examples: Windows, macOS, Linux.
- Roles of the Operating System (OS)
- Types and examples of operating systems
- Key functions of the OS (managing files, running applications, controlling hardware)
File Management: Organizing and managing files and folders.
- Understanding file paths and structures
- Navigating file systems and directories
- File naming conventions and extensions
- Backup and recovery methods
Networking: Connecting computers to share resources and information.
- Local Area Networks (LANs), Wide Area Networks (WANs)
- Networking hardware (e.g., routers, switches, modems)
- Types of network connections
- Protocols, and internet connections
Internet Applications: Accessing information and services on the Internet.
- World Wide Web (WWW), HTML, web browsers
- Types of web applications (e.g., e-commerce, social media)
- Common computer programs to access and utilize the internet
Security Basics: Protecting computer systems from unauthorized access and threats.
- Passwords, usernames, and access control
- Anti-virus software, firewalls
- Common threats to computer networks and security risks
Software Applications (Specific to Office Environment):
- Word Processors (creating documents)
  - Common features like formatting, tables, and inserting images, or diagrams
- Spreadsheets (managing data and performing calculations)
  - Common formulas, functions, and charting tools.
- Presentation Software (creating presentations)
  - Slide design and layout
  - Incorporating images and animations.
Computer Ethics:
