SMB (Server Message Block) and SMBClient are related to file sharing and network communication protocols used in Microsoft Windows operating systems.

 SMBClient, on the other hand, is a command-line utility available in some operating systems, including Windows and Linux, which allows users to interact with an SMB server.

SMB is the underlying protocol used for file and printer sharing in Windows networks, while SMBClient is a utility that allows users to interact with SMB servers from the command line. SMBClient is used to establish connections, browse shared resources, and perform file operations on remote SMB servers.
