Answer:
7 page faults
Explanation:
I have created a small Java program that can be seen in the attached picture below. This Java program uses an LRU algorithm in order to find the number of page faults within an array of page references from the references given in the question. Using these references, and the java program we can see that there are a total of 7 page faults. This can be seen in the output highlighted by red in the picture below.
Answer:
void showSquare(int param){
}
Explanation:
In C++ programing language, this is how a function prototype is defined.
The function's return type (In this case Void)
The function's name (showSquare in this case)
The function's argument list (A single integer parameter in this case)
In the open and closing braces following we can define the function's before for example we may want the function to display the square of the integer parameter; then a complete program to accomplish this in C++ will go like this:
<em>#include <iostream></em>
<em>using namespace std;</em>
<em>void showSquare(int param);</em>
<em>int main()</em>
<em>{</em>
<em> showSquare(5);</em>
<em> return 0;</em>
<em>}</em>
<em>void showSquare(int param){</em>
<em>int square = param*param;</em>
<em>cout<<"The Square of the number is:"<<endl;</em>
<em>cout<<square;</em>
<em>}</em>

Explanation:
The DNS server is said to be a caching-only DNS server.
A caching-only Domain Name System server, works by recieving queries from the client, proceeds to perform queries against other named servers, then caches the results and returns the results to the client.
Subsequent queries are resolved and returned for the specified host straight from the the cache, by the server, instead of submitting to the external server.
The advantage of this process is that it reduces traffic from outgoing DNS and speeds up the name resolution. Also, there is a reduction in the amount of query traffic.
