Long description

The figure shows a block divided into two segments labeled user space and kernel space. The user space segment contains a circular block labeled user program which represents user process pointed to a block labeled rest of the operating system which is given inside the kernel space segment. From the rest of the operating system block, three arrows point to three blocks labeled printer driver, camera driver, S S D driver. Again three arrows from these blocks point to another three blocks which come under the hardware part labeled printer controller, camera controller, S S D controller. These three blocks are connected to the printer, camera, and S S D devices.
