Answers

Answer 1

Explanation:

1.Data loss occurs when valuable or sensitive information on a computer is compromised due to theft, human error, viruses, malware, or power failure. It may also occur due to physical damage or mechanical failure or equipment of an edifice.

2.Automatic backup is a type of data backup model that requires little or no human intervention in backing up and storing data from a local network/system to a backup facility. Automating the backup process saves time and complexity required to manually back up a computer, network or IT environment.

3.A phishing attack is basically social engineering and identity theft that generally targets users with the aim to con them into revealing their personal and confidential information. In this technique, hackers send spoofed emails in the name of a legitimate source to victims and trick them into clicking on a malicious link or attachment to acquire their personal information. 

In many instances, these phishing scams use software or security vulnerabilities to install malicious software in the targeted user’s device. In any case, the human factor remains the key element in the successful phishing attempts of these cyber crooks. 

4.Equip your network, applications, and infrastructure with multi-level protection strategies. This may include prevention management systems that combine firewalls, VPN, anti-spam, content filtering and other security layers to monitor activities and identity traffic inconsistencies that may be symptoms of DDoS attacks.

5.While antivirus software helps to protect the file system against unwanted programs, a firewall helps to keep attackers or external threats from getting access to your system in the first place. Other threats travel from computer to computer without the knowledge of the user.

6.Proxy servers act as a firewall and web filter, provide shared network connections, and cache data to speed up common requests. A good proxy server keeps users and the internal network protected from the bad stuff that lives out in the wild internet.

7. The basic difference between these two types of encryption is that symmetric encryption uses one key for both encryption and decryption, and the asymmetric encryption uses public key for encryption and a private key for decryption.

8. A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.

Program Rock.java contains a skeleton for the game Rock, Paper, Scissors. Add statements to the program as indicated by the comments so that the program asks the user to enter a play, generates a random play for the computer, compares them and announces the winner (and why). For example, one run of your program might look like this:


Enter your play: R, P, or S


r


Computer play is S


Rock crushes scissors, you win!


Note that the user should be able to enter either upper or lower case r, p, and s. Add a loop to make sure the user only enters an R, P, or S. The user's play is stored as a string to make it easy to convert whatever is entered to upper case. Use if statements to convert the randomly generated integer for the computer's play to a string.


public class Rock


{


public static void main(String[] args)


{


String personPlay; //User's play -- "R", "P", or "S"


String computerPlay; //Computer's play -- "R", "P", or "S"


int computerInt; //Randomly generated number used to determine


//computer's play


// Add the code for each action beneath the comment. // more than one line may be needed in some cases // Get player's play -- note that this is stored as a string


// Make player's play uppercase for ease of comparison


// Generate computer's play (0,1,2) – use (int) (Math.random() * 3) to


// generate a random play


// Translate computer's randomly generated play to string // using mutually exclusive conditional statements


// Print computer's play


// See who won. Use nested ifs instead of &&.

}


People hardly ever play Rock, Paper, Scissors one game at a time. They play matches that are best 2 out of 3, best 3 out of 5, etc. Change your program to prompt the user for the odd number of games they want to play and use a loop to make sure it is an odd number. Then, add a loop to your program to play the game multiple times. Keep track of who wins, and make sure the loop stops when either the computer or the user has accumulated enough wins. Ties do not count in either the game total or the win totals – so a best 2 out of 3 match requires 3 games to be played where someone wins 2 times.
