This is not always true, it depends on the operating system and the bootstrap process.

How a operating system is related to computer hardware?
The operating system (OS) controls the hardware. A successful computer system will have hardware and an operating system. Application software is not required. All operating systems have a low level, or machine language to run the operation system and control all hardware.
What kind of software consists of the programs that control or maintain the operations of a computer and its devices?
This would be the operating system (or OS). The operating system controls and/or maintains the operation of a computer and its devices. Among other things, the OS manages the memory, does traffic control for the various programs, and loads drivers to control the low-level hardware functions to make the devices usable,
Is operating system the system software?
Most people think of the operating system as the system software. The operating system is the most important software on a computer. It controls the computer's hardware and provides a platform for other software to run on. Operating systems are complex and often have a lot of low-level code that is difficult to understand. They also have to be very reliable, as a crash can mean lost data or even physical damage to the computer.
What is the operating system of a computer?
The operating system serves many purposes. Talking at a high level operating system can be cosidered as a translator between user and computer(CPU).CPU or processor can understand only 0s and 1s, but the programs that we use today are written in somehigh level language like C or Java or something else. Now these programs ultimately had to be changed to 0s and 1s inorder to execute. This is the responsibility of Operating System. Then comes multitasking, we can execute multiple programs simultaneously in a single CPU, so this single execution core is shared among programs. This CPU management is also onus of Operating System.Not only CPU managent but many other resources are managed by Operatimg System like memory. Speaking at low level you cannot imagine a computer without Operating System. To facilitate access to the workings of the machine, which at its core only deals in zeros and ones.Without an operating system, you would have to manually type in instructions to the computer using machine code or a low-level language, and call functions.It would take several hours to be able to perform simple tasks such as typing word documents!Operating systems pre-load all the commands, information, and configurations the computer needs to perform tasks automatically, easily, and using a simple interface, such as mouse point-and-click or voice command, as well as streamlining general use and allowing simplified keyboard commands like control-alt-delete
Main tasks of operating system?
According to Andrew Tannenbaum, the creator of Minix and the author of Operating Systems: Design and Implementation, the two chief tasks of an operating system. The first function is to provide an abstraction layer above the hardware that is easier to program than the bare hardware. By providing this function, the user is freed from the need to worry about interrupts, timers, memory management and other low-level functions. The second function of an operating system is to manager all the various resources of the computer (CPU time slices, RAM, printing etc.) and dole them out wisely among all the various programs competing for them. As an example, let's look at the printer. Imagine if three programs were trying to send output to a printer at the same time. Without an operating system managing the resources, the result would be chaos: a few lines from program 1, a few lines of program 2, a few line from program 3, etc.
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.
What tells the computer how to use its resources?
The software that it is running. (Low level memory management itself comes down to the operating system though)
What is the use of resident monitor in memory management?
1. It is a Primitive Operating System. 2. Usually in low memory where interrupt vectors are placed. 3. It Isolate user from physical address space using logical address space
What program in an OS coordinates the memories by tracking which one is available which is to be allocated or deallocated and how to swap between the main memory and secondary memories?
The memory manager is the program responsible for managing memory allocation and deallocation in an operating system. It keeps track of which memory is available and allocates it to processes based on their needs. It also handles swapping data between main memory and secondary storage when the system runs low on physical memory.
What is stored within ROM memory?
ROM memory in a computer normally contains BIOS (Basic Input/Output System), which is the first program to run once a computer is switched on, before the operating system loads. It initializes and tests the system hardware. BIOS can be modified by flashing a new firmware, though it is not normally recommended.
Explain three functions that you would expect to find even in a minimal microkernel operating system?
low-level memory management, Inter process communication(IPC), I/O and interrupt management.

Why is MS-DOS better than Windows and Linux?
The only real advantage MS-DOS has over either of these operating system is it's low memory usage, whichcan be useful in the embedded field.
When viewing refrigerant through the liquid sight glass what is an indication that the system is low on refrigerant?
Bubbles visible in the glass with the system operating.Bubbles visible in the glass with the system operating.
When computer freezes what does that mean?
Low on system memory. or a driver and a software conflict.
What is read-only access memory?
READ-ONLY memory is protected against modification by a simple user Write Command. It is generally used to hold low level code such as the Instruction Set for the Computer Hardware itself. The typical application user can NOT address this memory area, but on their behalf, the Operating System can read the memory contents, but NOT modify it. Memory Chips of this type are typically FLASHED to make updates to their contents.
What is defined as the condition that occurs when your system is running out of virtual memory?
When a PC runs low on virtual memory, system activity causes what is called "thrashing", when memory is repeatedly paged out to, and read back from, the hard drive.
