The OS communicates with the CPU via the "kernel" - which is actually a core part of the OS.
When an operating system is loaded into memory, the kernel loads first and remains in memory until the operating system is shut down again. It should load into a protected portion of memory that cannot be written to by any other process. A computer kernel interfaces between the three major computer hardware components, providing services between:
- the application/user interface
- the CPU, memory
- other hardware I/O devices

Why CPU scheduling is require?
So that CPU utilise all the resources of OS
Roles of kernel in an operating system?
part of OS that allocates memory,CPU and other resources
What system provides a means for users to communicate with the computer and other software?
Operating! OS
Disadvantage of single user operating system?
Different types of operating systems have their disadvantages. In the case of a single user OS, it does not use the CPU, memory and other resources to the maximum. It also wastes a lot of CPU time since it executes one program at a time.
Why does the computer reboot before the operating system loads and just upgraded the computer's motherboard CPU and RAM?
Well, there are several reasons why it wouldn't boot to the OS. You could not have enough RAM to support the OS. If the CPU is overclocked too far it will not boot to the OS (heat or bus compatability issues) If the OS is unstable, or somehow the Kernel got altered (A Reformat would fix this) If you havn't reformatted since you installed the new MOBO, alot of times the OS will not boot There are a few others which i doubt apply to you, but I would try reformatting as this will most likely fix the problem. (Go into the BIOS and check your CPU temp, it should be running around 30, or 40 degrees Celcius) The operating system, which thought it was running on one lot of hardware, suddenly finds itself running on completely different hardware. It needs to be reinstalled so that it can configure itself for the new hardware. You can replace something like the hard drive or memory chips without that being necessary, but certainly not the motherboard.
How does an OS communicate to the CPU that it wants to access data on a hard drive?
By the north and south bridge.
How does the CPU communicate with a device?
There is no such thing as a CPU Drive. If you meant "What does a CPU communicate with", then the answer is everything inside your computer.
How does DMA module communicate with CPU?
DMA can communicate with CPU using Cycle stelaing process
Why CPU scheduling is require?
So that CPU utilise all the resources of OS
Can you multitask with a single CPU?
No you literally can not multitask with a single CPU, since one CPU can only process one task at a time, because with your 32-bit and 64-bit OS the OS allots CPU time to the application for a specific time then the OS preempts the processing to give the CPU to another application, the programs may appear to be multitasking but they are not, that is called preemptive multitasking.
Is CPU can directly communicate with hard disk?
CPU directly communicates with the Hard Disk.
What is 'OS' are our cpu's running off of?
Operating System
The software that allows the OS to communicate with a device is known as a?
Driver
What is the main function of CPU socket?
A CPU socket is a mechanical connection. Its main function is to serve as a connection that holds the CPU and allows it to communicate with the motherboard.
