NetBIOS/NetBEUI (networked basic input/output system/NetBios Enhanced User Interface)

A local area networking protocol developed by IBM and refined by Microsoft; originally, the native protocol for LAN Manager and Windows NT. IBM developed NetBIOS as a way to permit small groups of computers to share files and printers efficiently. NetBIOS is the original edition; NetBEUI is an enhanced version for more powerful networks in the 32-bit operating system.
