Common Internet File System / Server Message Block (CIFS SMB)

by Iwan Price-Evans on Glossary • December 12, 2019

It was developed by Microsoft and is a variation on the older SMB protocol.

It is designed for use over a wired low-latency network because its high operational communication overhead would produce noticeable performance degradation if used over a high-latency WAN network like the Internet. This protocol operates at the application or presentation layer of the OSI networking model.
