What are the commonly used communication devices in a computer network?
Hub: referred to as hub, which can be considered as a multi port interrupt device (one interrupt is dual port), and several of the above devices are network devices operating at the physical layerBridge: two LANs can be connected into a logical LAN. The network connection devices that work at the physical layer and the data link layerRouter: an interconnection device operating between multiple networks operating at the network layer. It provides routing options between networks
Interrupt device, also called transponder, extends the distance of the transmission medium, such as an Ethernet interrupt, that can be used to connect different Ethernet segments to form an Ethernet
Network adapter: also known as network interface card (NIC), it is plugged into the computer bus to connect the computer to other network devices. The network adapter usually only implements the function of the network physical layer and the data link layerNetwork transceiver: an interface device for network adapters and transmission media. It provides signal level conversion and signal isolationNetwork media conversion equipment: conversion devices between different transmission media in the network, such as twisted pair and optical fiberMultiplexer: a type of terminal controller used to improve the utilization of communication channels
