What is the name given to the process of initializing a microcomputer with its operating system?

• Cold booting

• Booting

• Warm booting

• Boot recording

Consider the following set of processes, the length of the CPU burst time given in milliseconds : Processes Burst Time Assuming the above process being scheduled with the SJF scheduling algorithm :

• The waiting time for process P1 is 0ms

• The waiting time for process P1 is 16ms

• The waiting time for process P1 is 9ms

• The waiting time for process P1 is 3ms

Preemptive Shortest Job First scheduling is sometimes called :

• HRRN scheduling - Highest Response Ratio Next

• Fast SJF scheduling

• SRTN scheduling - Shortest Remaining Time Next

• EDF scheduling - Earliest Deadline First

When a resource is released by a process, assignment edge reconverts to a request edge

• True

• False

The term "operating system" means

• the way a computer operator works

• the way a floppy disk drive operates

• a set of programs which controls computer working

• conversion of high level language into machine code

• UNIX

• Word processing

• Desktop publishing

• Spreadsheet

Which of the following command can be used as an alternative to echo command in Linux?

The function(s) of the Storage Assignment is (are)

• all of the choices

• to assign storage to literals, and to ensure that the storage is allocate and appropriate locations are initialized.

• to assign storage to all temporary locations that are necessary for intermediate results.

• to assign storage to all variables referenced in the source program.

The disadvantages of "Compile and Go" loading scheme is (are):

• a portion of memory is wasted because the core occupied by the assembler is unavailable to the object program.

• all of the choices

• it is necessary to retranslate the user's program deck every time it is run.

• it is very difficult to handle multiple segments, especially if the source programs are in different languages, and to produce orderly modular programs.

The strategy of making processes that are logically runnable to be temporarily suspended is called :

• First come First served

• Shortest job first

• Non preemptive scheduling

• Preemptive scheduling
