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.
