In the Many to Many thread model true concurrency cannot be gained because :
A thread shares its resources(like data section, code section, open files, signals) with :
In the Many to Many model when a thread performs a blocking system call :
In the Many to One model, multiple threads are unable to run in parallel on multiprocessors because :
A process stack does not contain
Logical memory is broken into blocks of the same size called _________
The segment base contains the :
In a paging system, it takes 30 ns to search translation Look-a-side Buffer (TLB) and 90 ns to access the main memory. If the TLB hit ratio is 70%, the effective memory access time is :
Every address generated by the CPU is divided into two parts :
In which one of the following page replacement algorithms it is possible for the page fault rate to increase even when the number of allocated frames increases?
Recently Used (LRU) page replacement policy. Assume that all the page frames are initially empty. What is the total number of page faults that will occur while processing the page reference string given below if it has 4 page frames?
4, 7, 6, 1, 7, 6, 1, 2, 7, 2
Increasing the RAM of a computer typically improves performance because:
Run time mapping from virtual to physical address is done by
What is compaction?
A memory buffer used to accommodate a speed differential is called
