. Select the advantages of RAID-5 relative to other RAID schemes. (MAY SELECT MULTIPLE)

Computers and Technology
1 answer:
Flauer [41]3 years ago
3 0

Answer: A) Very good on reads and D) Parity on separate disk

Explanation:

RAID-5 uses the disk striping with parity and it is a independent disk arrangement of the redundant array. As, the parity and data are placed in an even manner over the disk, in such a way that the bottleneck frame is not present in any disk.

In case of disk failure, the management of data can still be done with the help of stripping. Combination of parity and data stripping is one of the main advantage of RAID-5 and it is also very good in reading the data.

In cell E14, enter a date function that calculates the number of days between the Initial Deadline (cell E10) and the Date Recei
tatuchka [14]

Answer:

The formula to enter in E14 is as follows:

=DAYS(D14,$E$10)

Explanation:

Required

Formula to calculate the number of days between E10 and D14

The syntax to do this is:

=DAYS(end_date,start_date)

So, we have:

=DAYS(D14,E10)

The question requires a mix of relative and mixed references because cell E10 will be constant in calculating the difference for dates in other cells.

In other words, the initial date is constant for all

So, the update formula is:

=DAYS(D14,$E$10)

Notice the $ between in E10; this represents mixed referencing

When dragged to E15 till E68, the formulas in the respective cells will be:

=DAYS(D15,$E$10) .............................. =DAYS(D68,$E$10)

[20 pts] Write the function rectangle(perimeter, area), which takes two positive integers, perimeter and area. It returns an int
MrRissso [65]

Hi, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.

Answer:

import math

def rectangle(perimeter, area):

   l1_1 = (perimeter+math.sqrt((perimeter**2)-(16*area)))/4

   l1_2 = (perimeter-math.sqrt((perimeter**2)-(16*area)))/4

   l2_1 = area/l1_1

   l2_2 = area/l1_2

   print(l1_1,l2_1)

   print(l1_2,l2_2)

   if l1_1.is_integer() and l2_1.is_integer() and l1_1>0 and l2_1>0:

       return(int(max(l1_1,l2_1)))

   elif l1_2.is_integer() and l2_2.is_integer() and l1_2>0 and l2_2>0:

       return(int(max(l1_2,l2_2)))

   else:

       return(None)

Explanation:

  • We import math to make basic operations
  • We define the rectangle function that receives perimeter and area
  • We calculate one of the sides (l1_1) of the rectangle using the quadratic equation to solve 2h^2 - ph + 2a = 0
  • We calculate the second root of the quadratic equation for the same side (l1_2)
  • We calculate the second side of the rectangle using the first root on w = a/h
  • We calculate the second side of the rectangle using the second root on w= a/h
  • We verify that each component of the first result (l1_1, l2_1) is an integer (using the build-in method .is_integer) and greater than 0, if True we return the maximum value between them (using the max function) as w
  • If the first pair of sides evaluate to False we check the second root of the equation and if they meet the specification we return the max value
  • if all the if statements evaluate to false we return None to indicate that not positive or integer sides were found
