What language are you programming in? 
<span>If you are programming in C or C++, you could do something like this: </span>
<span>#include <iostream> </span>
<span>using namespace std; </span>
<span>int main(void) </span>
<span>{ </span>
<span>//declarations </span>
<span>double item1 = 0; </span>
<span>double item2 = 0; </span>
<span>double item3 = 0; </span>
<span>double item4 = 0; </span>
<span>double item5 = 0; </span>
<span>double subtotal = 0; </span>
<span>double total = 0; </span>
<span>double tax = 0; </span>
<span>//Enter Items </span>
<span>cout << "Please enter the price of item 1"; </span>
<span>cin >> item1; </span>
<span>cout << "Please enter the price of item 2"; </span>
<span>cin >> item2; </span>
<span>cout << "Please enter the price of item 3"; </span>
<span>cin >> item3; </span>
<span>cout << "Please enter the price of item 4"; </span>
<span>cin >> item4; </span>
<span>cout << "Please enter the price of item 5"; </span>
<span>cin >> item5; </span>
<span>//Compute subtotal </span>
<span>subtotal = (item1 + item2 + item3 + item4 + item5 + item6); </span>
<span>//Compute amount of tax </span>
<span>tax = subtotal * (.06); </span>
<span>//Compute total </span>
<span>total = subtotal + tax; </span>
<span>//Display subtotal, total, and amount of tax </span>
<span>cout < " The subtotal of the sale is: " << subtotal << endl; </span>
<span>cout < " The amount of sales tax is: " << tax << endl; </span>
<span>cout < " The total of the sale is: " << total << endl; </span>
<span>return 0; </span>
<span>}//end of function main </span>
<span>I know this is a very very basic C++ program but I hope it helps and good luck on your project!</span>
        
             
        
        
        
Solution:
It is  important because, it has to do operation on so without, data structures and algorithms. 
It performs these operation:  
  1)Take an input
2) Process it  
3) Give back the output.
The input can be in any form, for ex while searching for directions on google maps,  the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.
Similarly, in the third step, the computer application gives us output in some form or the other.
To make this process efficient, we need to optimize all the three steps. 
 
        
             
        
        
        
Do you have options? In my personal opinion, however, blur could be caused by motion blur, or focusing on the wrong thing, Hope this helps any!

Answer:
The answer is "Fiber Optic Cable".
Explanation:
In the given question options are defined, but in these options, there is some error.
The optical fiber cable is also known as internet wiring, which includes fiber strands inside an isolated housing. It is used to transferring data at a very high speed. This cable is developed for long-range data networking, high-performance connectivity, and multimedia, and other choices are wrong that can be described as follows: 
- A modem is used to transmits data over a network, that's why it is wrong.
- Router is used to transport traffic between your computer and the internet, that's why it is wrong.
