Answer:
CPU need 50% much faster
disk need 100% much faster
Explanation:
given data
workload spend time CPU = 60%
workload spend time I/O = 40%
achieve overall system speedup = 25%
to find out
How much faster does CPU need and How much faster does the disk need
solution
we apply here Amdahl’s law for the overall speed of a computer that is express as
S =
.............................1
here f is fraction of work i.e 0.6 and S is overall speed i.e 100% + 25% = 125 % and k is speed up of component
so put all value in equation 1 we get
S =
1.25 =
solve we get
k = 1.5
so we can say CPU need 50% much faster
and
when f = 0.4 and S = 125 %
put the value in equation 1
S =
1.25 =
solve we get
k = 2
so here disk need 100% much faster
Answer:
The answer is "False"
Explanation:
The data link layer is the protocol layer within a program, which controls data movement into a physical wireless connection. This layer is a second layer, that is also known as a collection of communications applications.
- The server network, in which many clients request, and receive service from a centralized server.
- This system provides an interface, that enables a user to request server services and view the server returns results, that's why it is wrong.
Answer:
There are additional security risks associated with using cloud computing over local data storage.
Explanation:
Cloud computing: The term "cloud computing" is described as a process through which an individual tends to access and store various programs and data over the internet rather than his or her computers' "hard drive". However, the term "cloud" here refers to a specific metaphor associated with the internet.
Types:
1. Software-as-a-service or SaaS.
2. Platform-as-a-service or PaaS.
3. Infrastructure-as-a-service or IaaS.
In the question above, the very first option is correct as all other options mentioned over here are incorrect because they aren't related to cloud computing.
Answer:
import random
def name_change( name: list ) -> list :
choice = random.choice( name )
choice_index = name.index( choice )
name.pop( choice_index )
return name
Explanation:
The python source code above makes use of the random package to select an item from a list in the function "name_change" and the index of that item is gotten fro the list and popped from the list "name", then the name is returned.
To call the function, assign it to a variable and add a list ( must be a list ) as its argument then print the result.
