*Do not support concurrent send and receive operation
*Cheaper then switches and routers
*Work on broadcasting methodology, So lot of traffic on the network that can lead to poor network response times

Switch
*Identify packet receiver address and forward only to them
*support concurrent send and receive operation
*Costly then hub and cheaper then routers
*Better network response time then hub
*Works on Data link layer and Network layer of OSI model

Router
*Connect two network either LAN or WAN
*It rout packet rather then transmit to computers link switch and hub
*Ensure proper delivery of packet.
*expensive than hubs and switches.
