802.1Q is a networking standard that supports Virtual LANs (VLANs) on an Ethernet network, allowing multiple networks to coexist on the same physical infrastructure without interference. It achieves this by inserting a VLAN tag into the Ethernet frame, which identifies the VLAN to which the frame belongs, enabling efficient traffic management and network segmentation.
Electrical standards and regulations are critical frameworks that ensure the safe and efficient operation of electrical systems, defining technical specifications, practices, and policies that all stakeholders must comply with.
