Answer:
In a buffer
Explanation:
We can define a buffer as a temporary holding area for data between the various devices and the CPU make I/O synchronization especially if there are multiple devices attempting to do I/O at the same time.
Items stored at the buffer helps to reduce the The incompatibilities in speed between the various devices and the CPU.

Answer:
C.<em> improve data quality and reduce redundancies, reduce increased and staggering storage management costs</em>
<em></em>
Explanation:
Excess data retention can lead to retention of redundant and irrelevant data, which can reduce data handling and processing efficiency, while at the same time increasing the cost of data storage and management. This can be curbed be reducing data to the right size by using data governance techniques like data cleansing and de-duplication
The correct answer is D. All of the methods listed above are ways of inserting new sheets into a workbook.
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
