What is an SMB Port + Ports 445 and 139 Explained
The Server Message Block Protocol (SMB Protocol) is a client-server communication protocol used for sharing access to files, printers, serial ports, and data on a network. It can also carry transaction protocols for authenticated inter-process communication. In short, the SMB protocol is a way for computers to talk to each other. SMB works through a client-server approach, where a client makes specific requests and the server responds accordingly. This is known as a response-request protocol.
