Question 11669 – File system-I/O-protection

Auxiliary storage is any storage that is made available to the system through input/output channels. This term refers to any addressable storage that is not within the system memory (RAM). These storage devices hold data and programs for future use and are considered nonvolatile storage that retains information even when power is not available. They trade slower read/write rates for increased storage capacity.

Auxiliary storage may also be referred to as secondary storage.

So all the given options are auxiliary memory.
