Answer:
plug-in
Explanation:
A Plug-in is a software that provides additional functionalities to existing programs. The need for them stems from the fact that users might want additional features or functions that were not available in the original program. Digital audio, video, and web browsers use plug-ins to update the already existing programs or to display audio/video through a media file. Plug-ins save the users of the stress of having to wait till a new product with the functionality that they want is produced.

Question options:
a. RAID 0
b. RAID 1
c. RAID 5
d. RAID 6
e. RAID 10
Answer:
d. RAID 6
Explanation:
RAID is Redundant Array of Inexpensive/Independent Disks. RAID combines low cost physical hard disk drives in one hard disk drive. RAID is used to achieve data redundancy(data backup but with synchronization) or improved performance or both.
To get what the director requires he would need to use RAID 6. RAID 6 is RAID level optimized to achieve data redundancy but with slow performance.
Answer:
def getChar():
while True:
in1 = input('Enter first char: ')
try:
if len(in1) != 1:
raise
else:
in2 = input('Enter second char: ')
if len(in2) != 1:
raise
else:
break
except:
print('Enter just one character')
return in1, in2
def chars2string(in1,in2):
print(in1*5 + in2*5)
def main():
ls = getChar()
in1 = ls[0]
in2 = ls[1]
chars2string(in1, in2)
if __name__ == '__main__':
main()
Explanation:
The programming language used is python 3.
The script first defines a function getChar and makes use of a while loop in combination with try and except blocks and IF statements, the code ensures that both inputs that are entered by the user after the prompt are 1 in length. i.e. Just one character. This function returns the two characters that were entered.
The second function that is defined is chars2string this function takes two arguments, It repeats each argument five times and returns a joined string.
Finally, the main function is defined and it calls the getChar function first, the values that are returned by this function is assigned to two variables, that is then passed on to the chars2string function. The main function is called and the Joined string is printed to the screen.
Answer:
The program to this question as follows:
Program:
def isEvenPositiveInt(x): #defining method isEvenPositiveInt
if x>0: #checking number is positive or not
if x%2==0: #check true condition
return True #return value True
else:
return False #return value False
return False #return value False
print(isEvenPositiveInt(24)) #calling method and print return value
print(isEvenPositiveInt(-24)) #calling method and print return value
print(isEvenPositiveInt(23)) #calling method and print return value
Output:
True
False
False
Explanation:
In the above Python program, a method "isEvenPositiveInt" is defined, that accepts a variable "x" as its parameter, inside the method a conditional statement is used, which can be described as follows:
- In the if block the condition "x>0" is passed, that check value is positive, if this condition is true, it will go to another if block.
- In another, if block is defined, that checks the inserted value is even or not, if the value is even it will return "true", otherwise it will go to the else part, that returns "false".
