VLANs (Virtual Local Area Networks) allow you to logically group devices within the same physical network into different broadcast domains, improving security and reducing unnecessary traffic.
The IEEE 802.11 standard specifies the protocols for implementing wireless LANs (Wi-Fi). In contrast, 802.3 is for Ethernet, 802.1X is for network authentication, and 802.15 is for personal area networks like Bluetooth.
Trunking enables multiple VLANs to traverse a single physical link between switches by tagging packets with VLAN IDs using protocols like IEEE 802.1Q.
Routers connect different networks, direct data packets between them, and manage traffic using IP addresses. Switches work within a single network, while hubs and access points serve different purposes.
WPA3 is the latest wireless encryption standard, offering stronger encryption and improved security for modern networks. WPA2 is still widely used but less secure than WPA3, while WEP and WPA are outdated and vulnerable.
