The computer itself cannot accomplish everything, it needs support from the hardware as well as support fro the hardware in order to accomplish the task it has been assigned to do. As a result, containers consume few system resources, such as memory, and impose essentially no performance overhead on the application. Embedded systems that have fixed deadlines use a such as , , , , and. To solve this problem, operating systems essentially dictate how every type of device should be controlled. Other operating systems are , separating the graphics subsystem from the kernel and the Operating System.
