what is the use of NETBUIE SERVICE?

Answer 1

Mapping drive to other computer shared folder

NetBIOS Extended User Interface (NetBEUI, pronounced net-booey, also known as NetBIOS Frame, or NBF) is an unrouted (non-routable) network- and transport-level data protocol most commonly used as one of the layers of Microsoft Windows networking. NetBIOS over NetBEUI is used by a number of network operating systems released in the 1990s, such as LAN Manager, LAN Server, Windows for Workgroups, Windows 95 and Windows NT.

The protocol is commonly confused with NetBIOS itself; NetBIOS is best thought of as a set of services provided to applications, with NetBEUI being a protocol that implements those services. NetBEUI can be seen as implementing NetBIOS over IEEE 802.2 LLC. Other protocols, such as NetBIOS-over-IPX/SPX and NetBIOS-over-TCP/IP (NBT), also implement the NetBIOS services over other protocol suites.

NetBEUI uses 802.2 type 1 mode to provide the NetBIOS name service and datagram service, and 802.2 type 2 mode to provide the NetBIOS session service (virtual circuit). NetBEUI makes wide use of broadcast messages, which accounts for its reputation as a chatty interface.

Sytek developed NetBIOS for IBM for the PC-Network program and was used by Microsoft for MS-NET in 1985. In 1987, Microsoft and Novell utilised it for their network operating systems LAN Manager and NetWare.

Because NetBEUI is an unrouted protocol, It can only be used to communicate with devices on the same network segment or segments that are connected to that segment via bridges. This means that it is only well-suited for small to medium-sized networks; it must be encapsulated within another protocol in order to be of use in a wide area network.

The use of NetBEUI has decreased quickly since the development of NetBIOS-over-TCP/IP.
