Answer:
RankBrain
Explanation:
RankBrain is a machine learning-based search engine algorithm, the use of which was confirmed by Google on 26 October 2015. It helps Google to process search results and provide more relevant search results for users.
Final answer:
RankBrain is Goog.le's AI system that helps interpret user searches for more effective results, considering factors like paid ads, popularity, and web connectivity. Search engine rankings are not based solely on content accuracy, so users should use approaches like SIFT to evaluate the credibility of information found online.
Explanation:
RankBrain is Goog.le’s machine-learning artificial intelligence system that interprets people’s searches to find pages that might not have the exact words they searched for. When using search engines like Goog.le, it's important to understand that results are not solely ranked based on authority, accuracy, or relevance. Instead, factors such as paid advertisements, popularity, and web interconnectivity can influence the visibility of web pages in search results.
As a result, it is possible for websites disseminating misinformation to manipulate search engine optimization (SEO) tools to boost their ranking in the search results. Therefore, users should exercise critical judgment and employ the SIFT method, which stands for the four moves of student fact-checkers, to assess the credibility of the sources they find online.
Why are models based on assumptions? A. Because models are not intended to analyze real-world events. B. Because models are only concerned about questions of equity, not question of efficiency. C. Because models have to be simplified to be useful. D. Because models are very different from theories.
Models are based on assumptions because models have to be simplified to be useful.
Answer: Option C.
Explanation:
Model is a computer program which helps to predict the situation as to what might have happened. Models are used almost in every aspect, be it economics or science or biology.
Assumptions are necessary because there are many complexity in every system and it is thus essential to have an understanding of the working of those system. It is necessary to remove the complexities for models to be useful. Models which aren’t based on assumptions are massive which is turn creates a problem. Thus it is necessary that models are simplified to be useful.
write a program to read in three nonnegative integers from the keyboard. Display the integers in increasing order.
Final answer:
To display nonnegative integers in increasing order, you can use a sorting algorithm like selection sort.
Explanation:
To write a program that reads in three nonnegative integers from the keyboard and displays them in increasing order, you can use a sorting algorithm such as selection sort. Here's an example in Python:
# Read in three integers from the keyboard
num1 = int(input('Enter the first integer: '))
num2 = int(input('Enter the second integer: '))
num3 = int(input('Enter the third integer: '))
# Create a list with the three integers
numbers = [num1, num2, num3]
# Sort the list in increasing order
numbers.sort()
# Display the integers in increasing order
print('Integers in increasing order:', numbers)
This program prompts the user to enter three integers, creates a list with those integers, sorts the list in increasing order, and finally displays the integers in increasing order.
n a poll, 6767% of Internet users are more careful about personal information when using a public Wi-Fi hotspot. What is the probability that among threethree randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot? How is the result affected by the additional information that the survey subjects volunteered to respond?
Answer:
The probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.964
If the survey subjects volunteered to respond , then those with the strongest opinions are most likely respond. The survey sample is then not randomly selected, the survey may have a response bias.
Explanation:
Let P(at least one is more careful about personal information when using a public Wi-Fi hotspot) denote the probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot, then we have the equation
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot)
If 67% of Internet users are more careful about personal information when using a public Wi-Fi, then 33% of them are not.P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot) = [tex]0.33^{3}[/tex] ≈ 0.036
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - 0.036 = 0.964
You've decided to use a subnet mask of 255.255.192.0 with your 172.17.0.0 network to create four separate subnets. The network ID for one of the subnets is 172.17.0.0. You are installing the first host (a server) on this subnet and want to assign the lowest numbered IP address possible to this system. What should you do?
Answer:
Assign the system an IP address of 172.17.0.1
Explanation:
Based on the information provided within the question it can be said that in this scenario you need to assign the system an IP address of 172.17.0.1 . This is because since you want the lowest possible IP address and since there is a subnet with an IP of 172.17.0.0 then the next lowest address would be by adding 1 to the last digit making it 172.17.0.1
Final answer:
The first usable IP address for the server on the subnet 172.17.0.0 with a subnet mask of 255.255.192.0 is 172.17.0.1.
Explanation:
To assign the lowest numbered IP address possible to the first host on the subnet with a network ID of 172.17.0.0 and a subnet mask of 255.255.192.0, you should use the first usable IP address in that range. The subnet mask of 255.255.192.0 indicates that the first two octets (172.17) are fixed for network identification, and the third octet will bring additional subnets.
The subnet mask divides the address space into four subnets, each incrementing by 64 in the third octet (since 192 in binary is 11000000). Thus, the possible subnets are 0, 64, 128, and 192. For subnet 172.17.0.0, the first usable address is the one immediately following the subnet address. You would therefore assign the IP address of 172.17.0.1 to the server, with the last octet as '1' since this is the first usable host address.
Consider the following code segment. int count = 1; int value = 31; while (value >= 10) { value = value - count; count = count + 3; } System.out.println(value); What is printed as a result of executing the code segment?
Answer:
30
26
19
9
Explanation:
Initially, the value of count is 1 and the value of the variable “value” is 31. Since value is greater than 10, the while loop condition holds true and the program enters the while loop and will continue to execute the code inside the loop until the value changes to less than 10. “value” is reduced in the statement “value = value – count;”. Since we know value is initially 31, and count is 1, the value after this statement is executed will become value=31-1 = 30. “count” variable is now incremented by 3, so it now becomes 1+3 = 4. The next line will print this value onto the screen. The loop run again since value is >= 10. In the second run, the value will decrement by 4 as count was incremented by 3 in the previous run. Therefore, the value would become 26, while the count is again incremented by 3 to its new value 7. In the next run, the value of the value variable is therefore decremented by 7 to its new value 19 (26-7=9), and count is again incremented by 3 to make it 10 (7+3=10). The value is decremented by 10 to its new value 9 in the next run. Since 9 is less than 10 the while condition is no longer true and the program exits the while loop.
The scheme where you can find the greatest common divisor of two integers by repetitive application of the division algorithm is known as the Brady algorithm.
Answer:
False
Explanation:
The scheme where you can find the greatest common divisor (GCD) of two integers by repetitive application of the division algorithm is known as Euclidean Algorithm.
The Euclidean Algorithm for calculating GCD of two numbers X and Y can be given as follows:
If X=0 then GCD(X, Y)=Y since the Greatest Common Divisor of 0 and Y is Y.If Y=0 then GCD(X, Y)=X since the Greates Common Divisor of 0 and X is X.Let R be the remainder of dividing X by Y assuming X > Y. (R = X % Y)Find GCD( Y, R ) because GCD( X, Y ) = GCD(Y, R ). Repeat the above steps again till R = 0.The work day has just started and you receive reports that the inventory management server is not accessible on your company's network.

Explain the difference between general-purpose and specialized applications. Also discuss the common features of application programs, including those with traditional and ribbon graphical user interfaces.
Answer:
General purpose programs are software that are designed for the general public, e.g. Word processor, music player, maps application. These softwares don't require you to be have some specific need or skill to use them.
Specialized programs are software that are designed for a specific group of users and/or profession, like CAD, Adobe premier, Visual Studio. These softwares require you to be associated with some profession to be able to use them. Also, specialized programs are usually not free and may require a licensing fee.
Common features of application programs include,
1. Saving file
2. Contact for help
3. Changing preferences
4. Exiting application
5. Viewing or signing in to your account
Explanation:
General-purpose computers can be configured to run various programs while special-purpose computers are designed for specific tasks. Apps are software applications that perform specific tasks and can feature either traditional or ribbon GUIs.
A general-purpose computer, like a universal Turing machine, is capable of running various programs, effectively transforming into a special-purpose computer for the duration of each program's execution. Special-purpose computers, on the other hand, are custom-built to run specific computations or tasks and cannot be dynamically reprogrammed.
Application programs, or apps, perform tasks separate from the core functioning of the computer, such as word processing, media playing, or accounting. These apps can have different user interfaces, with two common styles being traditional interfaces with dropdown menus and toolbars, and those with ribbon interfaces, popularized by Microsoft Office products, which organize tools into a set of tabs.
Graphical User Interfaces have evolved notably since the 1980s, with the introduction of elements like GUI, DTP, and WYSIWYG. These changes have significantly influenced how applications are interacted with and have broadened the application of computers.
