The system process is responsible for the system memory and compressed memory in the NT kernel. This system process is a single thread running on each processor. It is the host of all kind of drivers (network, disk, USB). The related file name is C:\Windows\System32\ntoskrnl.exe. The system process in Windows 10 has an additional task, compressing old pages of memory so that you have more free memory to use - often why this process may use a lot of memory itself. The system process has always the PID 4 (Process Identification) in the Windows Task Manager
