16.

num = float(input("Enter a number: "))

if num >= 0:

print(num**0.5)

17.

num1 = float(input("Enter the first number: "))

num2 = float(input("Enter the second number: "))

operation = input("Which operation would you like to perform (a/s/m/d): ")

if operation == "a":

print("{} + {} = {}".format(num1, num2, num1+num2))

elif operation == "s":

print("{} - {} = {}".format(num1, num2, num1-num2))

elif operation == "m":

print("{} * {} = {}".format(num1, num2, num1*num2))

elif operation == "d":

print("{} / {} = {}".format(num1, num2, num1/num2))

18.

The answer is algorithm

19.

The correct answer is C

20.

We analyze algorithms to see which algorithm is the best fit for the job.

I hope this helps!

Ask the user to type in an integer greater than 50 and assign it to a variable called x. Write a program to calculate the sum of

Zinaida [17]

Answer:

The solution in Python is as follows:

num = int(input("Number: "))

if num>50:

sum = 0

count = 0

for i in range(1,num):

count = count + 1

sum = sum + i**2

if sum > num:

sum = sum - i**2

count = count - 1

break;

print("Sum: "+str(sum))

print("Numbers: "+str(count))

else:

print("Number must be greater than 50")

Explanation:

The condition stated in the question do not conform with the example. The question says, the loop should stop when sum > x.

But:

When x = 100 and sum = 91, the program loop should not stop because 91 is not greater than 100.

However, I'll answer based on the example given in the question.

This prompts user for number

num = int(input("Number: "))

The following if condition is executed if number is greater than 50

if num>50:

This initializes sum to 0

sum = 0

This initializes count to 0

count = 0

The iterates through the inputted number (e.g. 100)

for i in range(1,num):

This increases the count

count = count + 1

This calculates the sum of square of the positive integer

sum = sum + i**2

The following removes excess number from the sum

if sum > num:

sum = sum - i**2

count = count - 1

break;

This prints the calculated sum

print("Sum: "+str(sum))

This prints the count of number used

print("Numbers: "+str(count))

The following is executed if user input is less than 50

else:

print("Number must be greater than 50")

Routing and remote access services allow users to connect to private networks using or:.

Luda [366]

Answer:

Users can connect to a remote access server through a dial-up connection or a virtual private network (VPN) connection.

Explanation:

A dial-up connection requires both the server and the client computer to have a correctly configured modem. The client and the server connect over analog public telephone networks. To enhance the security of a dial-up connection, use data encryption, Windows logon and domain security, remote access policies and callback security.

What is the name of the time delay in a CPU caused by differences between the speed o CPU, the system bus, and memory circuits?

Digiron [165]

Answer:

Option b is the correct answer for the above question.

Explanation:

The wait state is a state in which any process is waiting in a queue for his option. It happens when the other process is going on. It is because the CPU has not the capability to solve the problem of more processor. The above question asked about the name of the delay which is caused by the CPU for any processor then the answer is wait state because when a process is ready for the process but it is waiting for his turn then the state of the process is known as a wait state. so the Option b is the correct because it states about the wait state which is the correct answer which is described above but the other is not because--
