These calls are generally available as assembly language instructions System Calls CPU Calla Process Calls All of them Just like any other software, the operating system code can be structured in different ways. True or False True False In the Layered Approach , The bottom layer is the hardware; and the highest layer (layer N) is the ............... Graphical Interface user interface Multi-User Interface All of them In Layered Approach , A typical OS layer (layer-M) consists of data structures and a set of routines that can be invoked by .......... layers Low-Level High Level Middle level higher-level The method Which structures the operating system by removing all non-essential components from the kernel and implementing as system and user level programs is known as Mini Kernals Micro Kernal s Macro Kernals short Kernals Micro kernels typically provide ............... and memory management in addition to a communication facility minimum process Maximum process smaller larger By using CPU scheduling and virtual memory techniques an operating system can create the illusion that a process has its own memory with its own Memory Virtual Reality (virtual) memory (virtual) machine Java Virtual Machine (JVM) loads, verifies, and executes programs that have been translated into .............

I/O Bound Processes CPU Bound Processes Both A & B None of them ................spend more time doing computations, few very long CPU bursts. CPU Bound Processes I/O Bound Processes None of Them All of Them The state of a process is defined in part by the .......... activity of that process Previous Upcoming current All of them What operation is done in the type of Process named as "New" The process is being created. The process is being Deleted. The process is being updated. The process is being Selected. In Running Process state the Instructions are being ....... Loaded Deleted Released executed In Which Process State ?The process is waiting for some event to occur (such as an I/O completion or reception of a signal. New Waiting Running Ready In which process state , The process is waiting to be assigned to a processor. New Waiting Terminated Executed Ready In which process state ,The process has finished execution Finished Terminated Ready New Each process is represented in the operating system by a .............
