Question

Why is NetBIOS not used much in modern networks?

It has a maximum speed of 10 Mbps
It is incompatible with Windows 10
It uses a non-routable protocol
It uses IPv4 but not IPv6 addressing

Answer 1

NetBIOS is a non-routable protocol to where devices use names to communicate with each other. NetBT is NetBIOS over TCP/IP to allow TCP/IP networks, which are routable, to use NetBIOS.

Answer 2

The answer is: It has a maximum speed of 10 Mbps.

NetBios is an old protocol in a network and sometimes considered to have no use to new systems and networking software and devices. It is because stopping NetBios can help your network to work efficiently. NetBios has small processes that might cause slowing down network activities. Besides, there are new technologies that are much efficient compared to NetBios such as DNS configurations. The only thing to consider running NetBios is when DNS is not working or unavailable.
