The two advantages of modern operating systems is that it
has the capacity in helping programs to be loaded faster compared to other
older versions and it also has the ability of having to run programs that are
large enough in which is in the main memory even if it is smaller compared to
the size of its program.
Answer:
So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %
Explanation:
Previous concepts
Input/output operations per second (IOPS, pronounced eye-ops) "is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD)"
Solution to the problem
For this case since we have 4GB, but 512 MB are destinated to the operating system, we can begin finding the available RAM like this:
Available = 4096 MB - 512 MB = 3584 MB
Now we can find the maximum simultaneous process than can use with this:
And then we can find the maximum wait I/O that can be tolerated with the following formula:
The expeonent for p = 14 since we got 14 simultaneous processes, and the rate for this case would be 99% or 0.99, if we solve for p we got:
So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %
Answer:
Following are the correct code to this question:
short_names=['Gus','Bob','Zoe']#defining a list short_names that holds string value
print (short_names[0])#print list first element value
print (short_names[1])#print list second element value
print (short_names[2])#print list third element value
Output:
Gus
Bob
Zoe
Explanation:
- In the above python program code, a list "short_names" list is declared, that holds three variable that is "Gus, Bob, and Zoe".
- In the next step, the print method is used that prints list element value.
- In this program, we use the list, which is similar to an array, and both elements index value starting from the 0, that's why in this code we print "0,1, and 2" element value.
Answer:
The answer is the last option
There can be multiple definitions of Query in a database, however, If we go as per the definitions given above, i think most suited description is that the Query allows retrieval of information from multiple tables based on the criteria specified by the user.
