    Study Notes

    Year 9 Computing Mid-Term Revision

    • Hardware and Software Basics

      • Internal Hardware: Components inside a computer (CPU, GPU, RAM, ROM, motherboard).
        • CPU: Main processor for calculations and controls.
        • GPU: Specialized processor for images, videos, and animations.
      • External Hardware: Components connected externally to a computer (keyboard, mouse, monitor, printer, headphones, microphone, speakers).
        • Examples in table format provided.
      • Software:
        • System Software: Manages the hardware and provides a platform for applications (operating systems, utility software, compilers, device drivers, and backup tools).
        • Application Software: Designed for end-users to perform tasks (word processors, web browsers, etc).
          • Examples in table format provided.

    • Types of Computers

      • Desktop: High performance, less portable.
      • Laptop: Portable, moderate performance.
      • Tablet: Lightweight, touchscreen, light computing tasks.
      • Supercomputer: High computing power, used for complex calculations.
      • Server: Manages network resources, providing services to other computers.
        • Comparison table provided.

    • Operating Systems (OS)

        • Gesture-Based: Using physical gestures (gaming consoles like Nintendo Wii).
        • Comparison table provided.

    • Networking and Telecommunications

      • Networking Concepts:
        • IP Address: Unique number identifying a device (e.g., 192.168.1.1).
        • Domain Name: Human-friendly name for websites (e.g., google.com).
        • DNS: Translates domain names to IP addresses.
        • LAN: Local Area Network (small area like home or office).
        • WAN: Wide Area Network (large geographical area; examples include the internet connecting multiple LANs).
        • WLAN: Wireless Local Area Network (e.g., Wi-Fi).
      • Network Devices:
        • Router: Connects networks, directs data packets (often provides Wi-Fi at home).
        • Modem: Converts digital data to format for transmission over different connections (e.g., DSL, cable—often works alongside a router).
        • Bridge: Connects two separate networks; combines network traffic.
        • Hub: Basic device, broadcasts data to all connected devices.
        • Switch: Connects multiple devices in a LAN, directs data efficiently.
        • NIC: Network Interface Card (allows a device to connect).
      • Wireless Technologies:
        • Bluetooth: Short-range wireless technology.
        • Wi-Fi: Wireless networking technology.

        • NFC: Near Field Communication (short-range data exchange).

    • Cybersecurity

      • Passwords:
        • Weak Passwords: Simple, easy to guess (e.g., "password123").
        • Strong Passwords: Complex, including uppercase, lowercase, symbols, numbers.
        • Password Reuse: A significant security risk—if one site is compromised, attackers can access multiple accounts.
        • Password Managers: Securely store, manage, and generate unique passwords.
      • Social Engineering & Phishing: Manipulating users into revealing sensitive information.
        • Social Engineering: Psychological manipulation.
        • Phishing: Impersonating trusted entities (e.g., banks) to steal data (email, spear phishing, vishing, smishing).
      • Protection Measures:
        • Multi-Factor Authentication (MFA): Adds an extra layer of security.
