In most cases, device drivers are separate OS components that are loaded at boot time for each device present. They can be installed, upgraded, and uninstalled without affecting the rest of the OS$.$

An alternative method is to make all device drivers an integral component of the OS kernel so that a new kernel would have to be installed for each device driver change.

Consider the pros and cons of both methods, being sure to include the following points:

Security$$Which method is more secure$?$

Reliability$$Which method is more reliable?

Performance$$Which method provides better overall OS performance?

Flexibility$$Which method provides more OS flexibility?

Scalability$$Which method scales better?
