Network Switches

A Network switch is a type of network device used to connect multiple devices in a local area network (LAN). It can receive and forward data packets through physical or wireless interfaces, sending data packets from the source device to the target device. Network switches can identify and forward packets based on MAC addresses so that data can be accurately transmitted to the target device.

A network switch usually has multiple ports, each of which can connect to a device, such as a computer, server, printer, etc. When a device sends a packet, the switch forwards the packet to the corresponding port according to the MAC address of the target device, thus achieving communication between devices.

The network switch can also divide the virtual local area network (VLAN) into multiple logical subnets, so that different devices can communicate independently on the same physical network, improving network security and performance.

In short, a network switch is a network device used to connect and forward packets, which can realize communication and network management between devices. It is an important part of building local area networks and enterprise networks.
