NetBIOS stands for Network Basic Input/Output System. It's a networking protocol used for communication between devices on a local area network (LAN). Initially developed by IBM, NetBIOS enables applications and computers to communicate within a LAN.
NetBIOS provides services for naming, session establishment, and datagram delivery. It allows programs on networked computers to communicate with each other over the LAN, making it easier for them to find and connect to each other.
However, NetBIOS has security vulnerabilities and limitations, and it's considered somewhat outdated. Newer networking technologies like TCP/IP have largely replaced it. Nonetheless, some older systems and applications may still use NetBIOS for compatibility reasons.
