Basic Operating System MCQ
Basic Operating System MCQ
301. The Windows 2000, operating system supports
- Multiple user processes with single thread per process.
- Multiple processes with multiple thread per process.
- Single process with single thread
- Single process with multiple threads
302. In the pure User Level Threads (ULT)
- Thread management is done by application
- Thread management is done by kernel,
- Kernel is not aware of the existence of thread.
- Application program interface (API) to the kernel thread facility
303. The window 2000 (W2K) and Linux are the example of
- User Level Thread(ULT)
- Kernel Level Thread (KLT)
- A and B both
- None of these
304. The following is not an advantage of user level Threads (ULT).
- Thread Switching does not requires kernel mode privileges because all of the thread management are within the user address space of a single process.
- here scheduling can be application specific
- ULT can be run an any operating system.
- When ULT executes a system call, not only that thread blocked, but all of the threads within the process are blocked.
305. The linux operting system supports
- Single thread per process and single process.
- Multiple thread per process and single process.
- Single thread per process and multiple processes.
- Multiple thread per process and multiple processes
306. The vector and array processors fall into
- Single instruction single Data (SIS(D) stream
- Single instruction Multiple Data (SIM(D) stream.
- Multiple instruction Single Data (MIS(D) stream
- Multiple instruction Multiple Data (MIM(D) system.
307. In cluster
- Computers communicate with each other's via fixed paths or via some network fcilities
- Computer communicates with each other's via a shared memory
- Both (A) and (B)
- None of these
308. The cluster is a case of
- Distributed memory
- Shared memory
- Master/slave architecture
- Symmetric multi processor
309. The master/slave architecture is an example of
- Distributed memory processing
- shared memory processing
- Symmetric multi processing
- None of these
310. I/O modules in computer.
- Controls the operation of the computer.
- Stores data and program.
- Move data between the computer and external environment.
- Provides communication among processors and main memory
