which networking device is used to interconnect two LAN working on the same protocol and provide communication between them

Answer:
in addition to the beautifully written previous answers, I submit the following somewhat lengthy response. The answer is dependent on the specific definition of “protocol” and “LAN”. Reference to the ISO model may provide guidance. To put it simply, there are “protocol” standards for multiple “layers” of the OSI model, e.g. Layer 2 protocols include Ethernet (IEEE 802.3), and Token-ring (802.5). Layer 3 protocols include IP (IETF rfc 791) and IPX/SPX. The current de facto Layer 3 protocol in use for virtually all of today’s networks is the aforementioned IP protocol. Therefore, if you are asking the question “what is the network device that connects an *Ethernet* LAN to another LAN with the same *Ethernet* protocol, then the answer would include an Ethernet hub, bridge, or switch. If, however the question were to substitute *Ethernet* for *IP*, then the answer would be *router*, as routing devices provide the ability to connect devices which communicate using the same Layer 3 protocol (e.g. *IP*) on LAN’s of differing Layer 2 protocols (e.g. *Ethernet* to *Token-ring*).
