Answer:
Option D i.e., Backdoor is the correct answer.
Explanation:
Because backdoor is the virus that attack on the user's computer to provide unauthorized access to the hackers and it is very hard to detect, and in the following statement an issue occurred on the Ann's computer system when she open an invoice which is sent by any vendor then, several security warning appears on her system. So, that's why the following option is correct.
Answer:
Option A is the correct answer choice for the above question.
Explanation:
IT(Information technology) Security is used to secure Information technology which means to secure the information which is traveling through the internet for communication on the internet. It uses various security tools.
When any security method is developed for the first time then there will be a risk to develop it. Sometimes the result of risk will be positive and sometime it will be negative because--
- It is positive when the risk is being solved and the user achieved about the security which he is trying to develop.
- It is negative when the security designer did not achieve the right result for that research.
The above question also states the same which is described above hence true is the right answer for the above question.
Answer:
Explanation:
Algorithm:
a. In each day, you will have to loop through the hotels that come to the hotel after you stayed last night.
b. If a hotel 'h' is found at more than 'd' distance away from last stayed hotel, then the hotel previous of 'h' is chosen to wait for that night. This is the greedy step, and you stay in this hotel.
c. The process for steps a and b is then repeated until we've reached the last hotel xn.
Running time:
Notice that the worst case occurs if each hotel is at a distance of successive multiples of 'd'. The best move is to estimate the distance to each hotel twice the whole computation in the scenario.
Thus, the total running time that could occur in the worst case is O(2n) = O(n). This is said to be linear time.

Two solutions were found :
x =(2-√424)/2=1-√ 106 = -9.296
x =(2+√424)/2=1+√ 106 = 11.2
