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.
HTML5
HTML5 has fewer plug-ins like the ability to standardize how audio and video are presented on a Web page. It introduces the <video> element designed to remove the need to install 3rd party add-ons and plug-ins like adobe flash player. It also adds the <audio> element too that allows pages to smoothly add audio files.
Answer:
year = int(input("Enter a year: "))
if (year % 4) == 0:
if (year % 100) == 0:
if (year % 400) == 0:
print(str(year) + " - leap year")
else:
print(str(year) +" - not a leap year")
else:
print(str(year) + " - leap year")
else:
print(str(year) + "- not a leap year")
Explanation:
*The code is in Python.
Ask the user to enter a year
Check if the <u>year mod 4</u> is 0 or not. If it is not 0, then the year is not a leap year. If it is 0 and if the <u>year mod 100</u> is not 0, then the year is a leap year. If the <u>year mod 100</u> is 0, also check if the <u>year mod 400</u> is 0 or not. If it is 0, then the year is a leap year. Otherwise, the year is not a leap year.
