Question

Explain why the virtual memory implementation of hardware and OSes is also a security feature.

Answer 1

ANSWER;

In computers,we can implement virtual memory in both hardware and in software. Usually embeded systems needa strong security why becuase they handle lerge data and secure related transactions.Generally in standard virtual machine (VM) environment,root system’s I/O resources, like serial ports,USB etc., are organized as a generic pool, and these are generally assigned on a “as-needed” basis. But if we configure virtual memory implementation on hardware,those I/O resources are predefined by the topology to be in specific groupings by the administrator.Thus security exists while accessing those I/) resources.
