2. Device Drivers: Device drivers are programs that allow the operating system to interact with hardware devices. Examples include device drivers for printers, scanners, and other peripherals.
3. User Interface: The user interface is the part of the operating system that most users interact with. Examples include the Windows XP Start Menu, the Windows Vista Aero interface, and the Windows 7 Metro interface.
4. System Utilities: System utilities are programs that allow users to manage and configure the operating system. Examples include the Windows Task Manager, the Windows Registry Editor, and the Windows Disk Defragmenter.
5. File System: The file system is responsible for managing the files and folders on the computer. Examples include the NTFS file system and the FAT file system.
