The answer is 2 frequencies.
A Full-Duplex QAM 64 K Modem uses two frequencies. One frequency is used for upstream and the other for downstream. A variety of common QAM forms are available and include, 16 QAM, 32 QAM, 64 QAM, and 256 QAM. For example, for domestic broadcast use, 64 and 256 QAM are used for cable modem and digital cable TV. The modulation scheme for this modem uses both amplitude and phase.
Answer:
// program in Python to check perfect number
#function to find number is perfect or not
def is_Perfect_Number(n):
#total variable
tot = 1
i = 2
#sum of all divisor of number
while i*i<=n:
if n%i==0:
tot = tot + i + n/i
if tot == n and n != 1:
return 1
i = i+1
return 0
#read until user enter a perfect number
while True:
#read integer
num = int(input("Input an integer: "))
#call the function
if(is_Perfect_Number(num)):
print(num,"is perfect number")
#if perfect number break
break
else:
print(num,"is not a perfect number")
#ask again
print("try again.")
Explanation:
Read number from user and then call the function is_Perfect_Number() with parameter "num".This will find the sum of all divisor of number.If sum is equal to number then it will return 1 else return 0.If the number is not perfect then it will again ask to enter a number until user enter a perfect number.
Output:
Input an integer: 24
24 is not a perfect number
try again.
Input an integer: 28
28 is perfect number
Answer:
while True:
number = int(input("Enter a number: "))
product = number * 10
if product > 100:
break
print(str(product))
Explanation:
Create a while loop that iterates until a specific condition is created inside
Ask the user for the input
Multiply the input and put the result in product
Check if the product is greater than 100. If it is, stop the loop using break keyword
When the loop is done, print the product
Answer:
My Computer>>Properties>>Device Manager>>Video Card Properties>>Drivers Tab>>Roll Back Driver.
Explanation:
The user can do so by reverting the driver to the previous version, The correct process to do so is by the Right Clicking on the computer menu and clicking device manager from the properties. In the device manager, click the properties of the video card and select the Drivers tab. In the Drivers tab, click on the Roll Back Driver. This will restore to the previous driver.
