Answer:
Following is given the solution to question I hope it will make the concept easier!
Explanation:
Answer:
D.
Explanation:
In combinational circuits, the current output values are always the same for the same set of input values, regardless the previous values.
We say that combinational circuits have no memory, or that the circuit has no feedback from the outputs.
For sequential circuits, on the contrary, the current output values are not based in the current input values only, but on the previous output values as well.
So, the fact of having a defined set of input values at a given moment, doesn't guarantee which the output values will be.
We say that sequential circuits have memory, or that they have feedback from the outputs.
Examples of these type of circuits are R-S, J-K, D or T flip-flops.
Answer:
It is just true in most cases
Explanation:
This statement is just true in most cases because in some cases having a physical access to the computer or hard drive this does not guarantee access to the information contained in the hard drive or computer because the data/information in the hard drive or computer might as well be encrypted and would require a password in order to de-crypt the information.
Having a physical access is one step closer in some cases but not the only step required .
Answer:
The Solution Code is written in Java.
- public class Main {
- public static void main(String[] args) {
- System.out.print("Please enter an integer: ");
- Scanner input = new Scanner(System.in);
- int number = input.nextInt();
- System.out.print("Prime numbers less than or equal to " + number + " : ");
- for(int i=2; i <= number; i++){
- if(checkPrime(i)){
- System.out.print(i + " ");
- }
- }
- }
- public static Boolean checkPrime(int num){
- for(int i=2; i < num; i++)
- {
- if(num % i == 0){
- return false;
- }
- }
- return true;
- }
- }
Explanation:
Firstly, we create a function to check if a number is prime (Line 18 - 27).
- This function will take one input value which is an integer, num.
- To check if the input num is a prime, we can use modulus operator, %, to confirm if the num is divisible by any number starting from 2 to num - 1 (Line 19 - 24).
- If the num is divisible by any number expect 1 and itself, it should equal to zero and return false to indicate it is not a prime number.
- If all the num (except 1 and itself) is not divisible, the function will return true (Line 25).
Next, in our main program part (Line 3 - 16)
- Prompt the user to input a number (Line 5 - 7)
- Using a for-loop, we can keep calling the checkPrime() function by passing a current number (starting from 2 to input number) as argument (Line 12). The checkPrime() function will run and return true it the current number is prime, return false if it is not prime.
- If the checkPrime() function return true, it will print the current number before proceed to the iteration of the for-loop to repeat the same check prime procedure (Line 13)
- At the end all the prime numbers less than or equal to the input number will be printed out in the terminal
Answer:
Option A i.e., Detective.
Explanation:
When an organization, in a very bad area, recently started a new office. The manager installs a CCTV device for 24-hour surveillance of the area and entrance. So, the following scenario is about the detective control because If users start understanding that their actions are registered and tracked through authenticating into the computer to execute a function.
