Answer:
D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.
Explanation:
Most RAM (random access memory) used for primary storage in personal computers is volatile memory. Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost. Non-volatile memory has a continuous source of power and does not need to have its memory content periodically refreshed.
Answer:
Explanation:
RAM can be accessed faster than hard drive. – Any changes made to the file will be present in RAM while once the changes are saved it is copied to the hard drive permanently. – RAM needs power to store data, hard drives do not.

Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 2 ms, Job B = 12 ms, Job C = 15 ms, Job D = 7 ms, and Job E = 3 ms.
Using FCFS, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for each of these five jobs?
This is an example with solution:
Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 12, Job B = 2, Job C = 15, Job D = 7, and Job E = 3 ms.
a. Using FCFS, and assuming the difference in arrival time is negligible, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for all five jobs?
Answer: The order of processing for the given jobs = A->B->C->D->E.
Total time needed to process all the jobs = 12+2+15+7+3 = 39 ms.
Turn around time for job A = 12 ms.
Turn around time for job B = 15 ms.
Turn around time for job C = 30 ms.
Turn around time for job D = 37 ms.
Turn around time for job E = 40 ms.
Answer : Therefore, the average turnaround time = (12+15+30+37+40)/5 = 26.8 ms.
Order of processing is A, B, C, D, E and Total time to process and Average turnaround time is 39 ms and 24 ms
Turnover time and order of processing:Order of processing = A, B, C, D, E
Total time to process all five jobs = Job A + Job B + Job C + Job D + Job E
Total time to process all five jobs = 2 + 12 + 15 + 7 + 3
Total time to process all five jobs = 39 ms
Average turnaround time = [(2-0) + (2+12-0) + (2+12+15-0) + (2+12+15+7-0) + (2+12+15+7+3-0)] / 5
Average turnaround time = (2+14+29+36+39) / 5
Average turnaround time = 24 ms

Assume that the speed of new computers costing a certain amount of money grows exponentially over time, with the speed doubling every 18 months. Suppose you need to run a very time consuming program and are allowed to buy a new computer costing a fixed amount on which to run the program. If you start now, the program will take 7 years to finish. How long should you delay buying the computer and starting the program so that it will finish in the shortest amount of time from now
Therefore, in order to run the program in the shortest time, you should delay for 3 years
Given that the speed of new computers costing a certain amount of money grows exponentially over time, with the speed doubling every 18 months.
Exponential equation as a function of time can be expressed as
P(t) = [tex]P_{0}[/tex][tex]R^{t/T}[/tex]
Quantity P will be increasing exponentially when R > 1. And it will decrease exponentially when R < 1.
Suppose you need to run a very time consuming program and are allowed to buy a new computer costing a fixed amount on which to run the program. If you start now, the program will take 7 years to finish.
Let the time required to run and complete a program for time t years be P(t).
If the speed doubling every 18 months, which is 3/2 years. This will eventually cause the running time to decrease by half (0.5)
P(t) = 7[tex](1/2)^{3t/2}[/tex] = 7[tex](2)^{-3t/2}[/tex]
The total time T will be sum of the delay time t and the time of running the program. That is
T(t) = t + P(t)
T(t) = t + 7[tex](2)^{-3t/2}[/tex] .......... (2)
We can calculate the minimum time t by differentiating the above equation and make it equal to zero.
dT/dt = 1 + 14/3[tex](2)^{-3t/2}[/tex](ln0.5) = 0
14/3[tex](2)^{-3t/2}[/tex](ln0.5) = -1
[tex](2)^{-3t/2}[/tex](ln0.5) = -3/14
[tex](2)^{-3t/2}[/tex] = -3/14ln0.5
Log (natural logarithm) both sides
-3t/2ln2 = ln(3/14ln2)
make t the subject of formula
t = - 3ln(3/14ln2) ÷ 2ln2
t = 2.5 approximately
To know how long you should delay buying the computer and starting the program so that it will finish in the shortest amount of time from now, substitute t into equation 2
T(2.5) = 2.5 + (7)[tex]2^{-3(2.5)/2}[/tex]
T(2.5) = 2.5 + 0.5202
T(2.5) = 3.02 years
T (2.5) = 3 years approximately
Therefore, in order to run the program in the shortest time, you should delay for 3 years

Using the pandas packge in python, the program which performs the required calculation goes thus :
file_name = input()
#user types the filename
df = pd.read_csv(file_name, names=['hours_worked', 'rate']
#file is read into a pandas dataframe
df['salary'] = df['hours_worked'] * df['rate']
#salary column is created using the product of rate and hours worked

what are the main barriers to the adoption of an industry standard for internet system
Answer:
Industry experts say that although many companies find the potential of the Internet of Things very attractive, they either lack a clear value proposition for end-users or lack interoperability.
Describe the two problems that appear in the construction of large programs that led to the development of encapsulation constructs.
Two problems that can lead to the development of encapsulation constructs when creating large programs are the complexity of data and the lack of security in sensitive data.
We can arrive at this answer because:
Encapsulation constructs are designed to prevent data from being invaded by unauthorized person.These constructions must be done without causing inconsistencies in the system, interfering with codes, and increasing the complexity of data. For this reason, large programs that present high complexity and difficult codes, demand the use of encapsulation constructs, so that their data does not become more complex.Encapsulation constructs are also necessary when there are flaws in data security and it is not possible to keep them away from the attack by intruders.Although there are other ways to accomplish these goals, encapsulation constructs are widely used because of their simplicity and efficiency.

What is the difference between (IF instructions & WHILE instructions )
0
를 들
T
!
Answer:
While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.
If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.

Without proper synchronization, which is possible, a deadlock, corrupted data, neither or both? Give reasons for your answer.
need answer pls
Without proper synchronization, corrupted data is possible due to the fact that a shared datum can be accessible by multiple processes.
Data synchronization simply means the idea of keeping multiple copies of dataset in coherence with one another in order to maintain data integrity. It's the process of having the same data in two or more locations.
Without proper synchronization, corrupted data is possible because a shared datum could be accessed by multiple processes without mutual exclusive access.
