Answer:
B. False.
Explanation:
Cryptanalysis can be defined as the study, art or process of evaluating and analyzing information systems such as ciphertext, cryptographic systems and ciphers. The main purpose of Cryptanalysis is for a better understanding of how the cryptographic system works, in order to find techniques for deciphering, defeating or weakening them without an access to any privileged or secret data (information) required to do so.
Hence, cryptanalysis is made more difficult by having longer keywords as opposed to having shorter keywords which typically would make it easier for an attacker to decipher.
In a nutshell, it is false and incorrect to say that cryptanalysis is made more difficult by having shorter keywords.
Answer:
The correct answer is D.
Explanation:
In the given example, the task that the artificial intelligence system has to fulfill is to take control of an irregular task that is performed by humans. This requires a solution that depends on neural networks which work by evaluating given data sets and makes sense of them through the provided algorithms. They eventually come to a conclusion recognizing the relationships between the data points so that the system can decide what action to take. This procedure can be implemented to take control of the tax solution task that is performed by accountants.
I hope this answer helps.
Answer:
1) A string is "non-numeric data". In other words, it is text.
2) False, a runtime error means that there is a problem, but it will be with the software, not the hardware.
3) An impossible task such as dividing five by zero is a logical error. Not using quotes on a string would be a syntax error, printing an inaccurate statement is not an error at all (as far as the program is concerned anyway), and using camelcase on a variable with multiple words is a common convention.
4) variableName = "value"
5) The code provided here is illegible, so I can't give a straight answer. It seems to be missing operators.
Answer:
import java.util.Random;
class Main {
public int stopAtFive (int j) {
Random rand = new Random();
int number = 0;
for(int i=0; i<j; i++) {
number = rand.nextInt(9)+1;
System.out.println(number);
if (number == 5) {
System.out.println();
break;
}
}
return number;
}
public static void main(String args[]) {
Main main = new Main();
main.stopAtFive(20);
main.stopAtFive(20);
}
}
Explanation:
Your requirements do not say what has to be displayed or returned from the method, but you can use this as a starting point.
Answer:b)Reserve Room, Enter Contact Information, Enter Reservation Detail
Explanation: The use case is described as actors , actors goal, usage of use cases, units of scope and initial point and terminating point of use cases .
The situation mentioned in the question will take place for the reservation of the room through the instances in the form like filling the contact details for the identification , filling out reservation information as well for getting the knowledge about the room requirement by the person.
These details help in reaching out the particular person if required, number of days he wants to book the room,any extra facility he would like to have etc. After these detail filling activity the room can be reserved successfully.Thus , the most appropriate option is option (b).
Other options are incorrect because room reservation cannot be done without any formality as mentioned in the question and entering contact detail and reservation detail one by one.
