Answer:
Telephone conversation
Explanation:
Any real time conversations are synchronous.
Answer:
p(x,n)
1. if(n==0) [if power is 0]
2. then result =1.
3.else
4. { result=1.
5. for i=1 to n.
6. { result = result * x. } [each time we multiply x once]
7. return result.
8. }
Let's count p(3,3)
3
0, so come to else part.
i=1: result = result *3 = 3
i=2: result = result *3 = 9
i=2: result = result *3 = 27
Explanation:
here the for loop at step 4 takes O(n) time and other steps take constant time. So overall time complexity = O(n)
Answer: (D) Distributed denial- of- service (DDoS)
Explanation:
The distributed denial of service attack is one of the type of attack that occur when the multiple system are basically flooded with the resources and the bandwidth.
- Botnet is one of the example of DDoS as it caused the DOS (denial of service) for the users.
- This type of attack is more substantial as compared to the DoS attack as they use the multiple system for attack the single target simultaneously.
Therefore, Option (D) is correct.
