Network protocols are the set of predefined rules, used by the devices connected to network to communicate with each other.Different network protocols include NetBIOS/NetBEUI, TCP/IP and IPX/SPX.NetBIOS protocol is used for communication within a LAN and operates at the session layer of the OSI model.NetBIOS provides three types of services namely Name service, Session service and Datagram service.Name service allows an application to register its NetBIOS name in the network.Two computers can establish a session for data transfer using the Session service which is a connection-oriented service
In the connectionless Data gram service, data is transferred in the form of small packets called data grams.
NetBIOS name resolution is used to map a NetBIOS names to an IP address. Methods used for resolution are, NetBIOS Name Server (NBNS), NetBIOS name cache and Local Broadcast. LMHOSTS file is a static file that resolves the names to IP address for applications running on the remote computer.In the connectionless Data gram service, data is transferred in the form of small packets called data grams.
TCP is a connection-oriented, reliable and process-to-process transport layer protocol in the TCP/IP protocol suite.At TCP, data is divided into segments with each segment having sequence number for reassembly of the data at the destination.
