Short for Resource Monitor, Resmon is a feature introduced with Windows Vista that enables users to view real-time resource information about software and hardware on their computer. It shows things like memory, disk, CPU and network performance, as well as which software handles and file modules are working.

Below is an example of the Windows Resource Monitor in Windows 8 and type of information it provides to users.
