Answer:
Option (A) A successful WPS attack has occurred
Explanation:
- WPS stands for Wi-Fi Protected Setup.
- Its a network security protocol in the Wi-Fi which has a vulnerability.
- The connection to the Wi-Fi can be established through the router in four ways. They are
- (a) PIN method
- (b) Push button method
- (c) Near field communication method
- (d) USB Method.
- Out of all the modes to be connected to the network, the PIN method has a flaw in it.
- In this PIN method, an attacker can brute force the PIN (guessing the PIN by some techniques) and gain unauthorized access to the network.
- In the given case in the question, the network administrator finds that multiple unauthorized devices has gained access to the network.
- Option (A) is correct.
- Option (B) ARP Poisoning, (C) botnet and (D) Evil Twin attack are different and so are the wrong options.
Answer:
Module Program
Sub Main()
Dim num As Integer
num = 4
Console.WriteLine("The square of " & num & " is " & num * num)
Console.ReadKey()
End Sub
End Module
Explanation:
Very similar to the other program you posted.
Answer:
Explanation:
We start from the bottom-most and rightmost internal node of min Heap and then heapify all internal modes in the bottom-up way to build the Max heap.
To build a heap, the following algorithm is implemented for any input array.
BUILD-HEAP(A)
heapsize := size(A)
for i := floor(heapsize/2) downto 1
do HEAPIFY(A, i)
end for
Convert the given array of elements into an almost complete binary tree.
Ensure that the tree is a max heap.
Check that every non-leaf node contains a greater or equal value element than its child nodes.
If there exists any node that does not satisfy the ordering property of max heap, swap the elements.
Start checking from a non-leaf node with the highest index (bottom to top and right to left).
Answer: External
Explanation: External search could be explained as the additional information gathered beyond an individual's personal knowledge or experience in a bit to influence the individual's decision on a particular product or topic. This additional information could include; information sought from friends and families, online or internet research on relevant site, blogs or publications.
Therefore, a buyer who asks a friend, checking the internet or visiting a showroom or make other enquiries beyond his personal knowledge in other to make buying decision is making an external search.
When a website takes in personal information from a user, the owners of the website have no idea what was input, no matter how hard they tried. The information is not stored, and is used by Javascript APIs to locate your address to either ensure that it is valid, or so that you can choose your address.
It's completely safe, and if a website looks really, really sketchy, then just don't give them anything personal.
Another way to identify if a website is safe to give your personal information to is if you see "HTTPS" in the URL at the top of your browser. This means Hyper Text Transfer Protocol Secure, and is the protocol used to transfer information over the internet SECURELY, via encryption that only computers are able to decrypt, and will not show that information to owners of the server/website.
