Network Basic Input/Output System (NetBIOS) is an application programming interface (API) that facilitates communications between computers on a local network. It offers services like session establishment, name registration and resolution and message sending.

While it is an older technology, some Windows-based networks still use it for printing and file-sharing tasks.

Difference Between NetBIOS and Domain Name System (DNS)

Although NetBIOS and DNS offer name resolution services, DNS is a more efficient and scalable solution for the internet and bigger networks. On the other hand, NetBIOS is ideal for small local networks.

NetBIOS Security Considerations

Because of its design and age, NetBIOS is vulnerable to attacks like spoofing and traffic interception. To mitigate these risks, you should use modern technologies like DNS and secure network protocols.
