What are the commonly used network communication devices?
In the physical layer and data link layer network connection device. The switch: early switch equivalent multi port bridge. Router: work in multiple network interconnection equipment between the network layer. It can provide the path selection function in the network.
To improve the utilization ratio of communication channel. The interrupt: also known as transponders, extend the transmission distance of the media, such as ethernet repeater can be used to connect different Ethernet segments, to form an Ethernet hub.: short, hub, can be viewed as a multi port repeater (repeater is a dual port) more than a few the device is network equipment working in the physical layer. The bridge: the two LANs to a logical LAN.
The following equipment: general network adapter: also called the network interface card (NIC), plug it to other network devices connected to the computer in the bus on the computer, the network adapter in general only network physical layer and data link layer. The function of network transceiver interface equipment is: network adapter and transmission media. It provides isolation signal level conversion and signal.
