What is the operating system component that allows the operating system to use primary storage and process graphics?

A file manager is a utility that helps users organize and manage files on storage devices. While it provides an interface for users to manipulate files, it does not directly handle the low-level operations related to primary storage management or graphics processing, which are functions of the kernel.

The user interface (UI) is the means by which users interact with the computer system, encompassing visual elements and controls. While important for user experience, the UI does not manage hardware resources or execute commands related to storage or graphics processing, tasks handled by the kernel.

A driver is a specific type of software that allows the operating system to communicate with hardware devices, such as printers or graphics cards. While drivers facilitate the interaction between the OS and hardware, they operate under the control of the kernel, which is the component that ultimately manages operations related to primary storage and graphics.
