Answer:
B. False
Explanation:
A page-replacement policy can be defined as a set of algorithm that instructs the operating systems on what memory page is to be swapped, paged out or written to disk in order to allocate more memory as they're required by various active processes during virtual memory management.
Some of the algorithms or techniques used by the operating system for page-replacement policy are;
1. Last In First Out (LIFO).
2. First In First Out (FIFO).
3. Least Recently Used (LRU).
4. Least Frequently Used (LFU).
5. Optimal (OPT or MIN).
Hence, the page-replacement policy means that pages are placed to make more space and to minimize the total number of page that would be missing.
Answer:
Door locks
Light switches
Security cameras
Thermostat
Explanation:
IoT is internet of things that means network of different things that are interconnected through internet and make the decision with the help of Electronic sensors. The sensor sense the data from environment at different times and send this to the cloud (that may be the server). On the basis of this data different devices such as door looks, light switches, security cameras and thermostat take decisions with the help of controllers and change their current state.
<u>For Example</u>
In case of door look, there may be sensor that is sensing the finger prints of the user and after recognizing the person the door will be unlock. If unauthenticated user will try to open the lock a message has been sent to concerned. The training data of the the authorized persons is saved on the cloud, whenever someone tries to access, the data from sensor and cloud send to controller for making comparison and decision. So we can say that Door lock can be controlled IoT.
In case of light switches, there are few sensor available to sense the intensity of life. Different training values of that sensors are stored on the cloud. Whenever these sensors sense the light intensity, they send the data to the cloud contentiously, whenever the data match with darkness intensity, a signal has been send from controller to the switch to ON the lights.
Same as in cameras and Thermostat both are sending data to the cloud and controller. With the help of different image processing techniques and sensor camera will take the decision related to face recognition. Thermostat devices are also on and off by variation of temperature.
Integrity constraints are enforced by The database designer.
<h3>What are Integrity constraints?</h3>
An Integrity Constraints is known to be the protocols that a table's data columns is mandated to follow.
Note that they are used to hinder the types of information that can be put into a table and as such, Integrity constraints are enforced by The database designer.

Answer:
Go into setting; go to accounts; look for create account or add account; it will then come up with a tab asking what you want to create the for ( choose Email) it will ask who you want to create it for (yourself or Bussiness), you choose whichever you want and then fill in your information.
Hope this helps....
Explanation:
Answer:
int main()
{
int x,y;
bool b1, b2;
cout<<"enter values of x : ";
cin>>x;
cout<<"enter values of y : ";
cin>>y;
b1 = y > x; // false
b2 = x > y; // true
cout << "b1 is = " << b1 << "\n";
cout << "b2 is = " << b2 << "\n";
if (b2)
cout<<endl << "Larger Number" << "\n";
else
cout << "Smaller Number" << "\n";
return 0;
}
