The four major parts are: the kernel, process manager, file manager and scheduler
There are basically four types of operating systems. They include Batch Operating System, Multiprogramming Operating System, Network Operating System and Distributed Operating System.
An operating system is responsible for booting the computer and running programs. The operating system also keeps the system safe and runs drives.
Four of the most critical components controlled by an operating system are: CPU, RAM, Hard Drive and Motherboard.
The kernel is the essential center of a computer operating system the core that provides basic services for all other parts of the operating system. A kernel is designed to be a central core to the operating system - the logic that manages the resources that the hardware has to offer.
The four main components are: the Kernel, the Shell, the File system and Command
i don't know please!!
The four main parts of BIOS (Basic Input/Output System) are the Power-On Self-Test (POST), the Bootstrap Loader, the BIOS Drivers, and the Setup Utility. POST checks the hardware components for errors upon startup. The Bootstrap Loader initializes the operating system by locating and loading it into memory. BIOS Drivers provide the necessary software interface between the operating system and the hardware, while the Setup Utility allows users to configure hardware settings and system parameters.
