Test: Operating Systems

Explanation: The operating system is software which provides a buffer between the low-level interfaces to the hardware within the system and the user.

Explanation: The operating system is software that enables the users to utilise the system effectively.

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.

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

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.

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.

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.

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.

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

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