Operating System — Test 1

Correct Answer: B. B. Operating system
Explanation: The operating system is software that enables the users to utilise the system effectively.

Correct Answer: C. C. Operating system
Explanation: The operating system allows the software to be moved from one system to another and therefore, it can make the application program hardware independent.

Correct Answer: D. D. Program debugging tools
Explanation: The program debugging tools can speed up the testing process which can make the processor faster.

Correct Answer: C. C. Operating system
Explanation: An operating system is a software which includes its own I/o routine in order to drive the serial ports and the parallel ports.

Correct Answer: A. A. Kernel
Explanation: The kernel is the heart of the operating system. This can control the hardware and can deal with the interrupts, I/O systems, memory etc.

Correct Answer: B. B. Kernel
Explanation: The kernel is the heart of the operating system which can control the hardware and can deal with the interrupts, I/O systems, memory etc. It can also locate the parameter block by using an address pointer which is stored in the predetermined address register.

Correct Answer: D. D. Parameter block
Explanation: The kernel can locate the parameter block by using an address pointer which is stored in the predetermined address register. These parameter blocks are standard throughout the operating system, that is, they are not dependent on the actual hardware performing the physical task.

Correct Answer: C. C. Vmebus
Explanation: The software can be easily moved from one system to another which is more important for designing embedded systems, especially for those which use an industry standard bus such as VMEbus, in which the system hardware can be expanded or upgraded.

Correct Answer: D. D. Cp/m
Explanation: The first widely used operating system is the CP/M which is developed for Intel 8080 and the 8”floppy disk system.

Correct Answer: D. D. Cp/m
Explanation: The CP/M is a single task operating system, that is, only one task or an application can be executed at a time.
