These connections are established with either Router Hub or a Switch

• HUB - A non-intelligent device that broadcasts the data to all the systems in the network regardless of which system had generated the request.


• SWITCH - An Intelligent device, which unicasts the data to specific devices which requested. Switch recognized the systems with the help of a MAC Id which is the unique ID given to the NIC devices. MAC is an acronym for Media Access Controller.MAC is a 12 digit Hexa-decimal Character set which is unique to each of the devices and would be assigned a port number which is responsible to channelize the data transfer to specific systems.
