- User interface: It provides the user with a way to interact with the system, such as graphical or command-line interface.
- File system: The component that organizes and stores the data on the secondary storage devices.
- Hardware devices: The physical components of the computer system, such as CPU, memory, disk, keyboard, mouse, etc.
- Device drivers/control: The software modules that enable the operating system to control and communicate with the hardware devices.
- Networking: It is to simplify networking including an implementation of TCP/IP (standard Internet communications protocols) to automatically enable the Ethernet or wireless interface for a device.
