NetBIOS provides communication services on local networks. It uses a software protocol called NetBIOS Frames that allows applications and computers on a local network to communicate with network hardware and send data across the network.
What is the NetBIOS protocol?
NetBIOS, short for Network Basic Input/Output System, is a networking industry standard. It was created in 1983 by Sytek and is commonly used with the NetBIOS over TCP/IP protocol. However, it is also used in Token Ring networks and by Microsoft Windows.
Software applications on a NetBIOS network find and identify each other using their NetBIOS names. In Windows, the NetBIOS name is separate from the computer name and can be up to 16 characters long.
Applications on other computers can access NetBIOS names using UDP, a simple OSI transport layer protocol for client/server networking applications based on the Internet Protocol, on port 137.
