Device drivers are not needed for hardware to function. They act as an interface between hardware devices and the operating system. They are software programs that allow communication between the hardware and the operating system. They need to be installed and updated regularly to ensure proper functioning of hardware devices.
resource management data management job management The OS establishes a standard means of communication between users and their computer systems. It does this by providing a user interface and a standard set of commands that control the hardware

The software used to help run the computer hardware is known as an operating system. An operating system is a set of programs that manage computer hardware resources and provide common services for application software. It acts as an intermediary between the hardware and the user applications, facilitating communication and coordination between all components of the computer system. Examples of popular operating systems include Microsoft Windows, macOS, and Linux.
the HAL
The operating system (OS) manages hardware components, including the CPU, memory, storage, and peripheral devices. It acts as an intermediary between users and the hardware, facilitating resource allocation, process management, and device communication. By efficiently coordinating these components, the OS ensures smooth operation and optimal performance of the computer system.
A host operating system is the operating system that is in direct communication with the hardware. It has direct hardware access to kernel mode and all of the devices on the physical machine. The guest operating system runs on top of a virtualization layer and all of the physical devices are virtualized. A host operating system should be as modular and thin as possible to allow the virtualization of the hardware to be as close to the physical hardware as possible, and so that dependencies that exist in the host operating don't restrict operation in the guest operating system.Read more: What_is_the_relationship_between_a_guest_operating_system_and_a_host_operating_system_in_a_system_like_VMware_what_factors_need_to_be_considered_in_choosing_the_host_operating_system
