Study Notes
Module 1: Network Fundamentals
- A network is a system that allows multiple devices to communicate.
- Personal Area Network (PAN): A small network for personal use.
- Local Area Network (LAN): A network for a small area (home, office).
- Wide Area Network (WAN): Connects multiple LANs over long distances.
- Metropolitan Area Network (MAN): Larger than a LAN but smaller than a WAN.
- Virtual Private Network (VPN): A secure network.
- Network Interface Card (NIC): Hardware component for computer connection.
- Router: Typically connects a LAN to a WAN.
- Switch: Connects multiple devices within a LAN.
- Modem: Covers digital data.
- Access Point (AP): Allows wireless devices to connect.
Module 2: Network Simulation and Cabling
- Cisco Packet Tracer: Network simulation tool.
- Router/Router connection (WAN): Connecting two routers.
- Serial Cable: Use for long-distance connections.
- Router/PC connection: Used for testing or configuration.
- Crossover Cable: Similar devices (e.g., two PCs).
- Straight-Through Cable: Different devices (e.g., router to switch).
- Copper Crossover Cable: Connects two switches.
- Copper Straight-Through Cable: Connects a PC to a switch.
Module 3: Cyber Security Threats and Practices
-
Cybersecurity: Protecting systems from harm.
-
Cyber Threats: Malicious attempts to damage systems.
-
Malware: Malicious software.
-
Viruses: Attach to files/software.
-
Worms: Self-replicating programs.
-
Trojans: Disguised malicious programs.
-
Ransomware: Encrypts data and demands payment.
-
Spyware: Secretly monitors user activity.
-
Phishing: Fake emails to steal information.
-
Social Engineering: Manipulating individuals to obtain information.
-
Denial-of-Service (DoS): Overloads a system.

- Software Updates: Keep operating systems and software updated.
-
Network Security:
- Safe Browsing: Ensure websites are secure.
- Data Encryption: Transforming data into a secure format.
- Firewalls: Blocking malware.
Module 4: Data Protection Tools and Techniques
- Data Branches: Access points to the system.
- Antivirus Software: Detects, prevents, and removes malicious software.
- VPN (Virtual Private Network): Encrypts internet connections.
- Firewall: Security barrier.
- Encryption Tools: Convert sensitive data to unreadable code.
