The Monitor is the control portion of D3. It handles the hardware resources of the machine or passes requests to the host operating system and services requests for these resources from the D3 Virtual Machine. The Monitor performs:
Terminal I/O
Printer I/O
Tape I/O
Disk I/O
Memory Management /Disk Caching
The Monitor’s controller merely passes these requests from the Virtual Machine directly to the host operating system to be serviced.
