Answer: Computer viruses

Explanation:

Computer viruses are programs that need to be attached to other files to install themselves on computers without the users’ knowledge or permission and spread—sometimes very rapidly. A spyware is also a program that installs itself on a computer without the user's knowledge and tries to collect sensitive information such as passwords, credit card details and sends this information to a remote computer. A computer worm is a type of a virus that replicates itself across different computers. Freeware on the other hand is software that can be obtained for free.

How do you do this question?
elena55 [62]

Answer:

for (scores.Entry<String, Integer> entry : scores.entrySet()) {

          int value=0; String key="Rambo";

          String k = entry.getKey();

           int v = entry.getValue();

           if (v>value)

           {

               value =v;

           }

           else

           {

               value=value;

           }  

       }

       for( scores.Entry<String, Integer> entry : scores.entrySet())

      {

        if( entry.getValue()==value)            

        System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());

      }

Explanation:

The above scores are an object of Map type.  And this is a parameter of findUopStudent function. So scores is a Map, and entry is an item. And we get its key and value. Now we compare each value using senteniel method and find the maximum value. Now we iterate through the scores using for the look and check the value of each entry against the maximum value found, and we print out the entry with maximum value. And that is the top student, which is required.

hjlf

Answer:

a. A only

Explanation:

When air, is in excess of allowable amounts, it  can cause the system to operate at pressures that are higher than normal. This means that the recycled refrigerant is operating at high pressure. Thus Technician A is correct.

However, Technician B is incorrect because unlike reclaimed refrigerants where the process strip the refrigerant of impurities making it to meet the standards of a new refrigerant, the recycled refrigerant is not as pure as it's contaminants are only reduced.

Therefore, only technician A is correct.
