Answer:
4. A Denial of Service attack (DDOS attack).
Explanation:
A DDOS attack is a malicious attempt to disrupt the normal traffic to a service.
In essence, it sends an enormous amount of requests to the service, until the server is overwhelmed because it can't handle that much traffic, and collapses in an overflow.
Thus, regular users are not able to access their services.
Usually, attackers use a botnet, a network of "zombie" computers that have been previously infected with a malware that allows the attacker to remotely control them, then the botnet starts to send a flood of traffic from different locations, and make the attacker difficult to detect or track.
Answer:
if ( name1 > name2) {
first = name1;
} else {
first = name2;
}
Explanation:
First you need take a decision for that reason you need and if - else structure to decide if asign the variable name1 or the variable name2 to the result. Later you can use an > or < to compare two strings because it use the ASCII code to compare wich one is larger than another.
if ( name1 > name2) {
first = name1;
} else {
first = name2;
}
Answer:
This is correct. And to remove the confusion, I am adding the meaning of the Pseudocode. You need to begin with the algo that you are working upon, and then you need it to phrase the algo with the words which are easy to be transcribed in the form of the computer instructions. Now you need to indent the instructions properly inside the loop or within the conditional clauses. And while doing this, you need to not use the words which are used in certain forms of computer language. However, IF and THEN and ELSE and ENDIF are very frequently used as pseudo-code. Hence, your answer is correct.
