Today, a virtual area network or VLAN has become popular as network complexity has exceeded the capacity of the local area network (LAN). Every system connected in the network sends broadcasts or data packets to communicate with other devices in a broadcast domain. As the number of devices on the network grows, the network becomes latent. This is where VLAN is used to separate broadcast domains virtually, reducing the need to create a separate hardware LAN to overcome a large-broadcast-domain issue. VLAN avoids the physical limitation of a LAN with its virtual nature, allowing an organization to increase their network, segment it for security measures, and reduce network latency. Read More
Today, Ethernet media converters are gaining immense popularity owing to the beneficial features they offer.
