Which component of an operating system allows the operating system to run applications?

The user interface is the part of the operating system that interacts with the user, allowing them to communicate with the system through graphical or command-line means. While it facilitates user interaction and application accessibility, it does not directly execute applications or manage hardware resources.

Drivers are specialized programs that allow the operating system to communicate with hardware devices such as printers, graphics cards, or network adapters. While they are necessary for the functioning of hardware within the system, they do not play a direct role in the execution of applications themselves.

The file manager is responsible for organizing and managing files on the storage system, allowing users to create, delete, and manipulate files and directories. Although important for data management, it does not execute applications or serve as a bridge between applications and the hardware.
