Group9_dead lock: How do you think a LAN works?

LAN(local area netwok) is used to connect systems which are in short range. e.g for an institute which has to communicate regularly or a scientific research lab which has to share devices/resources worth lakhs. LAN are generally called hub switches in which other computer sit virtually. The main computer generally called the server will have a LAN card installed, In modern days Ethernet cards are used. The connection between LAN card and switches are done through RJ-45 cables. When a computer has to communicate with other for data transfer it establish a dynamic or static IP address. e.g 192.168.1.4 , after which the client can access any data or device on other LAN computer as if it was in the client machine itself. LAN can be used for bidirectional use like playing games which require continuous data exchange. while data is been transfered the data packets will have the ip address of the client which requested the transfer.
