In cyber security, an exploit is a way attackers take advantage of certain vulnerabilities and gain malicious access to systems. There are very many types of exploits that exist in the cyber security world. However, I will mention those ones most commonly used.
DoS attacks – The denial of service attacks is very common. Hackers will gain access to servers and send so many packet requests at the same time. The servers become overwhelmed due to too much memory allocation and the huge amount of traffic ends up crashing the servers.
Unauthorized access – When an attacker has an illegal access to host machines
<u>Application Exploitation</u>
Code injection – This exploit can be used to maliciously inject invalid code into an application program or software and as a result change how the program behaves.
Cross-site scripting – Enable hackers inject malicious scripts on a website of a client. Once they have gained access, they will escalate their privileges and have more access to the site.
Clickjacking – A type of attack that tricks unknown victims into clicking links of a web page they believe are legitimate and end up revealing confidential information of themselves.
Answer:
The answer is "except IOError:"
Explanation:
It is part of the exception handling, that stands for input/ output operation fails, this exception aeries when we attempting to access an anti-existent file, in the program so, it will give the program related errors.
- This type of error is handled in the try block, it also allows you to prepare the deal with the exceptional block.
- It also helps you to hide the bugs by using code, if you handle an unexpected error.

Answer:
a. 118.20.210.254
Explanation:
Here are the few characteristics of Class A:
First bit of the first octet of class A is 0.
This class has 8 bits for network and 24 bits for hosts.
The default sub-net mask for class A IP address is 255.0.0.0
Lets see if the first bit of first octet of 118.20.210.254 address is 0.
118 in binary (8 bits) can be represented as : 1110110
To complete 8 bits add a 0 to the left.
01110110
First bit of the first octet of class A is 0 So this is class A address.
For option b the first octet is : 183 in the form of bits = 10110111 So it is not class A address
For option c the first octet is 215 in the form of bits = 11010111 So it is not class A address
For option d the first octet is 255 in the form of bits = 11111111. The first bit of first octet is not 0 so it is also not class A address.
