An Ethernet switch is a networking device used to connect multiple wired devices like computers, printers, IP cameras, and servers in a Local Area Network (LAN). It has multiple RJ45 ports, and each device connects to the switch using an Ethernet cable.<\/p>\n\n\n\n
Unlike a simple hub that broadcasts data to all ports, a switch is intelligent; it sends data only to the specific device that needs it, which improves speed, reduces collisions, and makes the network more efficient.<\/p>\n\n\n\n
When a device sends data over the network, the data is broken into frames and forwarded to the switch. The switch reads the header of each frame and checks the MAC address<\/strong> (a unique hardware address) of the source and destination device.<\/p>\n\n\n\n The switch maintains an internal MAC address table<\/strong>, which maps MAC addresses to the physical ports. If the destination MAC is known, the switch forwards the frame only to that specific port; if it is unknown, the switch temporarily sends it out to all ports and learns the correct path when the destination responds.<\/p>\n\n\n\nMain Functions of an Ethernet Switch<\/h2>\n\n\n\n
