Answer:
XaaS
Explanation:
XaaS combines one or three main services in cloud computing, which are SaaS, IaaS, and PaaS. XaaS is a service not commonly used but is emerging quick and fast. XaaS is often generalized as a term that means the delivery of “anything-as-a-service.” Rather than providing solutions locally within a company, XaaS uses cloud computing technology to offer services. Xaas includes anything from an organization renting computing solutions over the internet through the cloud to a web programmer opening up an editor in his browser without the need to install the editor on his computer. Services ordered over the internet and purchased according to the needs of the consumer is referred to as XaaS.
Answer:
Here is the Python program:
def exec_2(f):
f()
f()
def exec_4(f):
exec_2(f)
exec_2(f)
def print_koala():
print("koala")
exec_4(print_koala)
Explanation:
The program works as follows:
First method:
def exec_2(f):
f()
f()
any function that is passed into exec_2() will be executed twice without parameters.
Second method:
def exec_4(f):
exec_2(f)
exec_2(f)
function exec_4(f) takes in a function f as a parameter and executes the function f 4 times using the function exec_2. At first exec_2(f) call the function f is executed twice and and second exec_2(f) call the function f is again executed twice so the function f executes 4 times in total.
Third method:
def print_koala():
print("koala")
a function that prints out the koala once
This function has a print statement which is passed the string koala to print on output screen.
exec_4(print_koala)
function exec_4 is used to print koala four times. This function exec_4 takes as argument the function print_koala() So this works as follows:
exec_4(print_koala)
The body of exec_4 executes as:
exec_2(print_koala)
exec_2(print_koala)
Now at first call to exec_2(print_koala) the program moves to the function exec_2 which executes print_koala() method twice. Since print_koala() method has a print statement print("koala") so this is executed twice:
koala
koala
Now at second call exec_2(print_koala) the program moves to the function exec_2 which executes print_koala() method twice again. Since print_koala() method has a print statement print("koala") so this is executed again twice:
koala
koala
So the output of the entire above program is:
koala
koala
koala
koala
The screenshot of program along with its output is attached.
