Answer:

d. all instances of a process with the same name matched by a regular expression

Explanation:

In Linux OS there is kill command that you can use to force applications to shut down. When you execute kill command, you are actually sending a signal to the system to force it to terminate the incorrectly behaving application.

The syntax for kill is:

$ kill [signal or option] PID

You have to know PID (Process IDentification number) of the desired process to complete this command.

The pkill command allows you to use advanced regex patterns and other matching criteria. Instead of using the PID, you can now terminate the application by entering the name of its process. For example, to shut down Firefox simply enter the command:

$ pkill firefox

Since it matches the regular expression pattern, you can also enter the name only partially, for example:

$ pkill fire

Given that it takes 0.08 ms to travel from one track to the next of a hard drive; that the arm is originally positioned at Track

daser333 [38]

Answer:

Time taken to travel from one track to the next = 0.08ms

Initial track= 15 0

4 (15-4)*(0.08)= 0.88

40 (40-4)*(0.08)= 2.88

35 (40-35)*(0.08)= 0.4

11 (35-11)*(0.08)= 1.92

14 (14-11)*(0.08)= 0.24

7 (14-7)*(0.08)= 0.56

----------------------------------------------

Total seek time=0.88+2.88+0.4+1.92+0.24+0.56=6.88ms

Explanation:

We caculate the seek time for each request, and then add them together to find the total seek time. The final track number for the current request becomes the current track of next request, and this process is repeated till the last request is processed.

Triss [41]

Joel is a victim of a security breech. By leaving his computer unattended and not locked, he allowed for another person to use his credentials to access (or attempt) to access information that would otherwise be restricted to him. The fact that the unauthorized person did not find the information he was seeking does not minimize the risk.
