The combination of dedicated devices and shared devices those devices are called as vertual devices.

Device management controls peripheral devices by sending them commands in their own proprietary language. The software routine that knows how to deal with each device is called a "driver," and the OS requires drivers for the peripherals attached to the computer. When a new peripheral is added, that device's driver is installed into the operating system

Well, the most fundamental probably are:- processor management- memory management- file management- device management (in some OSes, devices are represented as files)what are the four functions that all operating systems provide?

It might be called "reserved virtual memory space" or "virtual memory file", depending on the operating system.

Virtual Layer
The virtual page offset is important in memory management because it determines the location of data within a virtual memory page. This offset helps the operating system map virtual addresses to physical memory locations efficiently, allowing for better memory utilization and organization.

Monolithic Kernel is also known as "Macro Kernel" A monolithic kernel (Macro Kernel) is an operating system architecture where the entire operating system is working in the kernel space and alone as supervisor mode. The monolithic differs from other operating system architectures (such as the microkernel architecture) in that it defines alone a high-level virtual interface over computer hardware, with a set of primitives or system calls to implement all operating system services such as process management, concurrency, and memory management itself and one or more device drivers as modules.
KVM, or Kernel-based Virtual Machine, is a virtualization technology integrated into the Linux kernel that enables the host operating system to run multiple isolated virtual environments or virtual machines (VMs). Each VM has its own operating system and can operate independently, allowing for efficient resource utilization and better management of hardware resources. KVM transforms the Linux kernel into a hypervisor, enabling features like live migration, virtual CPU management, and device emulation. It is widely used in data centers and cloud computing for running multiple workloads on a single physical server.
The only virtual machine that currently support USB passthrough to allow a guest operating system to use a USB device connected to the host is VirtualBox.
