Network Fundamentals and Simulation Quiz

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.
Man-in-the-Middle (MitM): Interrupts communication between parties.
Insider Threats: Attacks by trusted individuals.
Zero-day Exploits: Unpatched vulnerabilities.
3 Best Practices for Online Security:
- Strong Passwords: Combine letters, numbers, and symbols.
- Two-Factor Authentication (2FA): Requires two forms of verification.
- 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.
