Correct Answer: Runnable
Explanation:
The process states of unix are running,Zombie,stopped,Waiting.
Correct Answer: The repeated execution of a loop of code while waiting for an event to occur is called busy-waiting The CPU is not engaged in any real productive activity during this period, and the process does not progress toward completion
Correct Answer: Kernel follows Round Robin scheme choosing a swap device among the multiple swap devices in Unix System V
Correct Answer: Load Sharing: Processes are not assigned to a particular processor A global queue of threads is maintained Each processor, when idle, selects a thread from this queue Note that load balancing refers to a scheme where work is allocated to processors on a more permanent basis Gang Scheduling: A set of related threads is scheduled to run on a set of processors at the same time, on a 1-to-1 basis Closely related threads / processes may be scheduled this way to reduce synchronization blocking, and minimize process switching Group scheduling predated this strategy Dedicated processor assignment: Provides implicit scheduling defined by assignment of threads to processors For the duration of program execution, each program is allocated a set of processors equal in number to the number of threads in the program Processors are chosen from the available pool Dynamic scheduling: The number of thread in a program can be altered during the course of execution
Correct Answer: swapping interactive user request timing parent process request
Correct Answer: Bootstrap Program
Explanation:
The program that is responsible for loading the operating system into RAM is the bootstrap Loader program.
Correct Answer: /user/lib/games/Chess.class
Explanation:
/user/lib/games/Chess.class could be the possible location of the file
Correct Answer: 6-4-4
Explanation:
Default permissions given to a file are:
Owner - read write and execute - 6
group - write - 4
others - write - 4
Correct Answer: Computer program
Explanation:
A computer program is a collection of instructions that performs a specific task when executed by a computer
Correct Answer: C++
Explanation:
C++ is not an Operating System.
An Operating System is a collection of system programs that manages all the other programs application programs in a computer as well as the allocation and use of hardware resources such as the CPU, Memory and the Hard Disk Drive.
It acts as an interface between the hardware and the user level program.
It controls and facilitates the overall operation of a computer.
Here
UNIX : UNIX is a popular multi-user, multitasking operating system (OS) developed at Bell Labs.
Windows NT : Windows NT is a family of operating systems produced by Microsoft, the first version of which was released in July 1993.
DOS : DOS is Disk Operating System. The term DOS can refer to any operating system.
C++ : C++ is a programming language and computing platform.
Hence, C++ is not an Operating System.
