CS604 Midterm Paper of Operating Systems - Dated: 28 Nov 2011
Q1: You wanted to add
descriptor 1 or 0 before the "<"or">"sing in Grep command shell
accept or reject these descriptor.write the names of shell that can
accept these descriptor? (2)
Q2:
suppose you are working on Linux machine and require to check the process information.how can u view the process information? (2)
Q3:
there are two assumptions below
1)each process execute at a nonzero speed.
2)no assumtion can be made regarding speed of the N process.
u can be solved by useing these instruction? (2)
Q4:
busy waiting is one the main charateristic of samphore.u have to identify that whether
busy waiting is effective or deaffective for samephor?(3)
Q:5:
Suppose tha athrea mapping .user level thread to kernel level threads.many kernel level threads and there exst no cuncurerncy between these threads.write down the name of mosel in the above scenario for mapping threads (3)
Q6:
Describe the tow issue regarding the process and how the threads overcome these issues(5)
Q7:
Data race detection method can be broadly categorized into static race detection and dynamics race.Lets as assume race detection which instruments the program and monitor Its execution inline or offline.data race detector is not typically analyzes source or byte code without directly executing the program.these data race detection be classified into ……based on whether the model a happens befor relation lock set or both u need to identify which dara method is used?(5)
