The BigFix CLIENT is common for all IBM products that are BASED on the BigFix platform, and it is used to perform MULTIPLE tasks on the endpoints. The client provides information about a set of computer properties like the host name or the IP address, and it is a tool that is used to install the scanner on the computers, and manage the scanner through fixlets.
The scanner, on the other hand, is an independent component that is used by LMT/BFI. It collects information about the hardware and software that is installed on the computers in your infrastructure. The data that is then SENT to the BigFix server, can be imported to the LMT/BFI server.
