Why does an operating system reside in low memory?
This is not always true, it depends on the operating system and the bootstrap process.
What is the memory resident portion of the operating system?
The Kernel
It is possible to launch one operating system from another operating system or on top of another operating system?
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.
What will effect if an operating system cannot perform memory deallocation?
/
How does the operating system of a computer manage the computers resources?
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.
Operating system manges memory?
An Operating System manages resources. Memory is one example of resource management.
Part of operating system?
How is a memory-resident part of an operating system different from a nonresident part of an operating system?
Is kernel memory permanent memory?
No it is RAM memory used by the operating system
What is a kernel?
The central module of an operating system. It is the part of the operating system that loads first, and it remains in main memory. Because it stays in memory, it is important for the kernel to be as small as possible while still providing all the essential services required by other parts of the operating system and applications. Typically, the kernel is responsible for memory management, process and task management, and disk management. The definition of kernel is "the portion of an OS (Operating System) that is responsible for interacting with the hardware. It is the operating system software that runs in kernel mode on the computer's processor and which provides low-level intelligence for the operating system. In other words, the kernel is the "heart" of an operating system.
When does the operating system creates virtual memory?
when the actual memory is full
What is responsible for managing memory?
operating system
Why is it important to check the minimum system requirements when installing an operating system?
The operating system is loaded into the computers internal memory (RAM) at start-up. The operating system needs to 'reserve' chunks of memory to enable it to perform its functions swiftly and accurately. If a computer doesn't have enough RAM, the computer cannot run the operating system efficiently, often using empty hard-disk space - which slows down the computer.
Is an operating system responsible for managing processor time and memory allocation?
The processor time is a function of the processor. The memory allocation is a function of the operating system.
Why does an operating system reside in low memory?
This is not always true, it depends on the operating system and the bootstrap process.
When is it important to get an update for an application or an operating system?
When is it important to get an update for an application or an operating system?

What is the core of the operating system that manages memory?
