1. Networking Basic Fundamentals. Exploitation in Cyber Security : Definition: Networking is the practice of connecting computers, servers, and devices to share data, resources, and services. Purpose: Enables communication, internet access, and resource sharing like files and printers. Example: Connecting your laptop to home Wi-Fi is networking. --- 2. Router Definition: A router is a device that forwards data packets between different networks, like your home network and the internet. Purpose: Connects multiple networks and directs traffic efficiently. Example: Your home router connects your Wi-Fi devices to the internet. --- 3. Switching Definition: Switching is the process of directing data packets between devices within the same network using switches. Purpose: Ensures data reaches the correct device efficiently within a LAN. Example: In an office, switches send data from one computer to another without involving the internet. --- 4. Trunking Definition: Trunking is a technique that allows multiple VLANs (Virtual LANs) to share a single network link between switches. Purpose: Efficiently carries traffic for multiple VLANs over one physical connection. Example: A single trunk link between two switches carrying traffic for VLAN 10 and VLAN 20. --- 5. EtherChannel Definition: EtherChannel is a method to combine multiple physical links into a single logical link for higher bandwidth and redundancy. Purpose: Increases speed and provides network reliability. Example: Combining 4 Ethernet cables between two switches to act as one 4x faster link. --- 6. WLAN (Wireless LAN) Definition: WLAN is a local area network that connects devices wirelessly using radio signals. Purpose: Eliminates cables while providing network access. Example: Home Wi-Fi connecting your phone, laptop, and smart devices. --- 7. STP (Spanning Tree Protocol) Definition: STP prevents network loops in switch networks by selectively blocking redundant paths. Purpose: Protects networks from broadcast storms caused by loops. Example: In a network with multiple switches, STP ensures only one path is active for data. --- 8. ACL (Access Control List) Definition: ACL is a set of rules that control which traffic is allowed or denied on a network device. Purpose: Provides security and traffic management. Example: Blocking unwanted IP addresses from accessing your network. #trending #viral #fyp #usa #trend - @cybernetsec
