Answer:
The quicksort pivot is an arbitrary element within the collection that is being sorted. Using the pivot point, the collection of elements is partitioned into two smaller lists of elements. Using some logic, the smaller elements are placed left of the pivot point, and larger elements are placed to the right of the pivot point. Ideally, you would prefer you pivot point to be a median of your dataset to optimize the creation of the two sublists into a balanced state.
Cheers.
The pivot of a quicksort algorithm ought to always be the element in the middle. Some algorithms will choose the item in the center as the pivot, while others will choose the first or last element.
What is quicksort algorithm?Quicksort is a sorting method that operates in-place. It was created by British computer scientist Tony Hoare and is still a widely used sorting algorithm.
When properly implemented, it can be slightly faster than merge sort and two or three times faster than heapsort.
The quicksort pivot can be any element in the collection being sorted. The collection of elements is divided into two smaller lists of elements using the pivot point.
Smaller elements are placed to the left of the pivot point, while larger elements are placed to the right of the pivot point.
To optimize the creation of the two sub-lists into a balanced state, you would prefer your pivot point to be the median of your dataset.
Thus, this way quicksort works.

As the security administrator for your organization, you must be aware of all types of attacks that can occur and plan for them. Which type of attack uses more than one computer to attack the victim?
Answer:
The answer is "DDoS "
Explanation:
The distributed denial of service attack (DDoS) occurs whenever a directed program's wireless data or assets, generally one or even more application servers, were also swamped by various machines. This attack is always the consequence of many affected systems, that fill up the target network with traffic.
This attack is aimed to avoid legal customers of one's website from accessing it. In being effective in a DDoS attack, further demands need to be sent to the hacker than even the victim's server could deal with. One other way to successfully attack is to send fake requests from the attacker.In python,_______ are used to define the conditions necessary for a while loop to run.

Question 55 :You use a computer named Wkst1 on a TCP/IP network, which is installed with an application that uses UDP to send a file from your computer to a computer named Wkst2. Data collisions occur, and several data packets are lost during transmission. What will most likely occur as a result of losing the packets during transmission?
Answer:
The protocol will drop the packets
The application will automatically re-transmit the packets
Explanation:
Based on design, the routers will drop the packets as allowed by the Internet Protocol, due to the collision that resulted from the router being busy and the network is congested or that the packet is corrupt as indicated by the check sequence of the Ethernet frame or the IPv4 header checksum
Given that the application uses User Datagram Protocol (UDP) which does not allow recovery of lost packets, but have their defined methods of overseeing lost packets, as such the application will re-transmit the packet.

Can you recommend me a movie?
The game begins with the player having 20 POINTS
The player rolls 2 six sided dice and the sum of faces on the two dice are calculated. That’s called the players POINT.
If the POINT is a 7 or 11, the player wins his POINT
If the POINT is a 2, 3, or 12, the player loses his POINT
If the POINT is anything else, then the game continues by the player rolling the two dice again and again recording and checking the sum until
The player makes his point (The sum of his dice roll equals his POINT value) and then he wins his POINT
The player rolls a 7 and then he loses his POINT.
The player is considered a winner if he can acquire 60 POINTS and is considered a loser when he runs out POINTS
After the program has finished, display the total number of rolls of the dice that were made in the entire game.

Explanation:
In the above-given python code, a method "rolling_dice" is declared, inside the method two-variable "dice1 and dice2" is declared, that uses the random method to calculate the value in both variable and use the return keyword to add both values.
In the next step, another method the "rolling" is declared, inside the method "n_roll and p" is declared that assigns the values and use the two while loop, inside the loop if block is defined that calculates the values.

Answer:
A reverse proxy.
Explanation:
A service that might appear to be a single server to external clients, but actually represents many servers living behind it, is known as a reverse proxy.
In Computer Networking, a single server can be configured to appear as the endpoint for many other servers acting behind it through the use of a reverse proxy.
Hence, a reverse proxy is a type of server that is placed right in front of other servers such as a web server and forwards or routes the user's (client) requests to those servers sitting behind it. When properly configured, reverse proxy helps to ensure security, reliability and performance of a network.

Mary uploaded some images on her website. She chose an image and downloaded it. She found that the image she saw on screen did not seem to have the same DPI as when she had scanned it (she had uploaded a scanned image with 300 DPI). What could be reason with this visual decrease in DPI on the computer screen? (Correct Answer only)
A. Some image resolution was lost while uploading it
B. She downloaded a compressed version of the image.
C. The computer reset the resolution of the image.
D. Her file was probably corrupted while downloading.
E. Computer screens typically display images of only 72 DPI.
The reason for this visual decrease in DPI on the computer screen is some image resolution was lost while uploading it. The correct option is A.
What is resolution?Resolution is the quality of the image that we see in the screen. It is the number of pixels per inch of space. The meaning of PPI is pixel per inch. When a high-resolution picture is seen, it means there are more pixels per inch.
When a picture is downloaded from a site. It does not download in the original pixels because during downloading some pixels are lost due to slow net or the settings of the computer. And a compressed version does not download on its own, and corrupted files do not affect the resolution.
Thus, the correct option is A. Some image resolution was lost while uploading it.
