An Operating System manages resources. Memory is one example of resource management.
How is a memory-resident part of an operating system different from a nonresident part of an operating system?
No it is RAM memory used by the operating system
when the actual memory is full

The processor time is a function of the processor. The memory allocation is a function of the operating system.
This is not always true, it depends on the operating system and the bootstrap process.

Certain versions of the Linux operating system can be installed on and booted from a memory stick.
Depending on the base operating system, yes. In almost all cases, the operating system from which the second one is loaded lacks memory protection, allowing the second operating system to replace the first one in memory. This can be used, for instance, to boot Linux from MS-DOS or classic versions of Mac OS.
One of the main things the operating system manages is the memory. The operating system contains a memory manager, dispenses memory to applications, and keeps track of what is used. It also consolidates and defragments the memory and returns relinquished memory back to the pool of available memory.The operating system uses drivers to match itself to the exact hardware that is in the system and to provide ways to use and manage the hardware.The operating system uses the storage drivers to provide APIs to manage disk I/O, and it uses file system drivers to manage the file systems needed to store files.
