What does a network switch do

4. Layer-2 devices like switches an WAPs get IP addresses for management. There are unmanaged switches which don't get, and don't have an option for, IP addresses because they don't need them since they are not managed. Some WAPs (LWAPs) don't get configured with IP address as you normally would, but they get an IP address from …

Network switches use filtering to manage network traffic. They examine the header of each data frame and use the destination IP address to determine which port to forward the frame to. Quality of Service (QoS) is a feature that prioritizes certain types of data, ensuring that critical network services receive the bandwidth they need. Ethernet switching connects wired devices such as computers, laptops, routers, servers, and printers to a local area network (LAN).

Network hubs and network switches serve similar purposes but switches offer a number of additional, more advanced functions. Hubs are sometimes referred to as “dumb devices.” This is because they broadcast all incoming packet data indiscriminately to every single computer connected to them.Much of today’s Internet traffic travels across a lot of switches: many fast, reliable, and affordable switches to be specific. A network switch or Ethernet switch are the heart of the network and is an essential building block of the network which connects different devices together. There are different kinds of network switches available like KVM, …Switching Process. Switches reduce network overhead by forwarding traffic from one segment to another only when necessary. To decide whether to forward a frame, the switch uses a dynamically built table called a bridge table or MAC address table. The switch examines the address table to decide whether it should forward a frame.
