Typically, operating systems have a .... for each device controller. This device driver understands the device controller and provides the rest of the operating system with a uniform interface to the device.

In system view, we can view an operating system as a ............ A computer system has many resources that may be required to solve a problem : CPU time, memory space, storage space, I/O devices, and so on.

• resource allocator

• control program

• resource utilization

• ease of use

The operating system is the one program running at all times on the computer -- usually called the .....

• kernel

• application

• middle ware

• shell

The CPU hardware has a wire called the ............. that the CPU senses after executing every execution. When the CPU detects that a controller has asserted a signal on the interrupt-request line, it reads the interrupt number and jumps to the interrupt-handler routine by using that interrupt number as an index into the interrupt vector
