Answer:

False

Explanation:

It's the other way round actually. Arraylists do not have fixed size and can increase or decrease in size as needed. On the other hand, Arrays are fixed from when they are declared; they have a particular size that number of elements cannot go beyond.

An arraylist in Java is a class that is part of a Java collection framework(java.util) that can have variable sizes and only store objects, not primitive data like strings or integers. An array is a data structure in Java and can store both primitive data and objects, while having a fixed size at declaration.

Answer:

Explanation:

The following function/program is written in Java. It asks the user for a sentence as an input and then splits that sentence into an array of words. Then it creates an arrayList for all of the unique words, comparing each word in the sentence with all of those in the ArrayList. If a word is found in the ArrayList it cancels the loop and moves on the next word in the sentence. Finally, it counts all of the unique words in the ArrayList and prints that total to the screen.

public static void uniqueWords() {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter a sentence:");

       String sentence = in.nextLine();

       String words[] = sentence.split(" ");

       ArrayList<String> uniqueWords = new ArrayList<>();

       for (int x = 0; x < words.length; x++) {

           boolean exists = false;

           for (int i = 0; i < uniqueWords.size(); i++) {

               if (words[x].equals(uniqueWords.get(i))) {

                   exists = true;

                   break;

               }

           }

           if (exists == false) {

               uniqueWords.add(words[x]);

           }

       }

       System.out.println(uniqueWords.size());

   }

Answer:

Cheese c =new Velveeta( );

Food f =new Velveeta( );

Food f =new Cheese( );

Explanation:

The super-class is the parent class from which features and attributes are inherited from while the subclass or the child class is the class inheriting from the super or parent class.

In Java, the object instance of a class is created with the syntax;

class_name instance_name = new class_name();

Food is the super or parent class of Cheese (which makes Cheese its subclass) and Cheese is the parent class of Velveeta. The extends keyword is used to denote inheritance.

Answer:

A) copyright

B) copyright

C)Trade mark

D) copyright

E)Patent

Explanation:

Patent can be regarded as a form of intellectual property which helps the owner of an invention to others to sell or use the invention for some period of time. Example of this is a patent that protect microwave oven.

trademark is form of intellectual property, this could be inform of symbols, words that differentiate the product of a party from another. Example of this is a bite of apple that represents apple products.

Copyright can be regarded as a legal right given to those that owns a intellectual property which gives him/her right to copy and exclude others from reaping from where they did not sow. The owner get exclusive right to reproduce the copy.

Below is the match of the intellectual property with the examples.

a. books, poems<> Copyright

b. music, movies, paintings<> Copyright

c. company logo<> Trademark

d. software<>Copyright

e. combinations of materials to make drugs<> patent

Answer:

a. 7 bits

b. 8 bits

c. 9 bits

d. 24 bits

Explanation:

Required

Number of bits per word

The formula to get the number of bits per word is:

[tex]2^n = N[/tex]

Where

n = bits

N = numbers

Solving (a) 0 to 100

There are 101 digits between 0 and 100 (inclusive)

So:

[tex]N = 101[/tex]

Substitute 101 for N in [tex]2^n = N[/tex]

[tex]2^n = 101[/tex]

101 can not be expressed as an exponent of 2.

So, we substitute 101 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

[tex]2^n = 128[/tex]

Express 128 as an exponent of 2

[tex]2^n = 2^7[/tex]

Apply law of indices

[tex]n = 7[/tex]

Hence, 7 bits are required

Solving (b): 0 through 255

There are 256 digits between 0 and 255 (inclusive)

So:

[tex]N = 256[/tex]

Substitute 256 for N in [tex]2^n = N[/tex]

[tex]2^n = 256[/tex]

Express 256 as an exponent of 2

[tex]2^n = 2^8[/tex]

Apply law of indices

[tex]n = 8[/tex]

Hence, 8 bits are required

Solving (c): 0 through 256

There are 257 digits between 0 and 256 (inclusive)

So:

[tex]N = 257[/tex]

Substitute 257 for N in [tex]2^n = N[/tex]

[tex]2^n = 257[/tex]

257 can not be expressed as an exponent of 2.

So, we substitute 257 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

[tex]2^n = 512[/tex]

Express 512 as an exponent of 2

[tex]2^n = 2^9[/tex]

Apply law of indices

[tex]n = 9[/tex]

Hence, 9 bits are required

Solving (d): 0 through 10000000

There are 10000001 digits between 0 and 10000000 (inclusive)

So:

[tex]N = 10000000[/tex]

Substitute 10000000 for N in [tex]2^n = N[/tex]

[tex]2^n = 10000000[/tex]

10000000 can not be expressed as an exponent of 2.

So, we substitute 10000000 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

[tex]2^n = 16777216[/tex]

Express 16777216  as an exponent of 2

[tex]2^n = 2^{24[/tex]

Apply law of indices

[tex]n = 24[/tex]

Hence, 24 bits are required

Answer:

Ping the other workstations from the IT Admin workstation to confirm that connection has been lost, check the status of the network interface card in the workstation with command ifconfig in the terminal, then reset the connection using ifdown and ifup commands. If the problem is not resolved, check the cable connection.

Explanation:

Ping is an ICMP echo message sent by a network host to another to check for connectivity. If they are connected, the other workstation responds with an ICMP response message.

The ifconfig in Linux systems displays the network adapters and their individual IP configurations. If there is no connection even after the network is reset, then the cable connectors could be the problem.
