Three-tier architecture refers to the structure of web applications that are built with three main layers.
Three-tier architecture can be described as a program that establishes a link between the public and server as it segregates the software into three layers named the presentation tier, the logic tier, and the data tier.
The presentation tier is concerned with the client as it sends contents to the client's browser and hence serves as a means for the interaction between the user and the web application.
The logic tier is the part that includes the server program that receives the information from the presentation tier and then processes the collected information.
The data tier provides support and security to the application and is the part that stores the processed data.
In this type of architecture program, each tier can be managed independently by a different squad of people and changes can be made to any tier without altering the rest of the tiers.

After some years, the bookstore has enough ratings that it starts to use a more advanced recommendation system, matrix factorization-based methods, like the one won the Netflix prize. Suppose the mean rating of books is 3.4 stars. Alice, a faithful customer, has rated 350 books and her average rating is 0.4 stars lower than average users’ ratings. Animals Farm is a book title in the bookstore with 250,000 ratings whose average rating is 0.7 higher than global average. What would be a baseline estimate of Alice’s rating for Animals Farms? Explain
The baseline estimate of Alice's rating for Animal Farm would be 3.4 - 0.4 + 0.7 = 3.7 stars.
Matrix factorization is a popular technique used in recommendation systems to predict user ratings for items. It decomposes the rating matrix into two smaller matrices, one for users and one for items, with a lower dimension. This approach allows for more efficient and accurate recommendations by identifying latent factors that contribute to user-item interactions.
To estimate Alice's rating for Animal Farm, we can use the baseline approach, which involves adding a user-specific bias and an item-specific bias to the global mean rating. The user-specific bias accounts for the tendency of a particular user to rate items higher or lower than the global average, while the item-specific bias accounts for the tendency of a particular item to receive higher or lower ratings than the global average.
To calculate Alice's user-specific bias, we first need to calculate her average rating deviation from the global mean. Given that Alice's average rating is 0.4 stars lower than the global average, her user-specific bias would be -0.4.
Next, we need to calculate the item-specific bias for Animal Farm. Given that its average rating is 0.7 stars higher than the global average, the item-specific bias for Animal Farm would be 0.7.
Finally, we can estimate Alice's rating for Animal Farm by adding the global mean rating, the user-specific bias, and the item-specific bias together. Thus, the baseline estimate of Alice's rating for Animal Farm would be 3.4 - 0.4 + 0.7 = 3.7 stars.
Overall, the baseline approach is a simple yet effective method for predicting user ratings in recommendation systems. It takes into account the user and item-specific biases and the global mean rating to provide a personalized estimate of user ratings for items.

Click cell C6 in the Data worksheet and insert a column. Type Series Name in cell C6. Click cell C7 in the Data worksheet and insert a lookup function that identifies the series code, compares it to the series legend, and then returns the name of the series. Copy the function you entered from cell C7 to the range C8:C22. Change the width of column C to 18.
Answer:
I was able to obtain an image of the "Data Worksheet" referenced (attached).
First we click on the C6 cell, and click the "Insert column" toolbar button.
Then on the same cell we type the column name "Series Name"
On the cell below (C7) we'll type the VLOOKUP function as follows:
=VLOOKUP(B7;$A$2:$C$4;2)
FIrst argument (B7) is the term to search
Second argument ($A$2:$C$4) is the table containing the terms to search and the results to return.
Notice the use of $ to avoid errors while copying the formula.
The third argument (2) means the function will return the 2nd column from the "Series Legend" cells.
Finally we'll copy the formula in C7 and paste it to the cells below C8 to C22.
To resize the column just drag the right side on top of the column, mouse icon will change to a double-pointed arrow.

We have to paint n boards of length {A1, A2…An}.There are k painters available and each takes 1 unit of time to paint 1 unit of the board.
How to solve the problem?The problem is to find the minimum time to get
this job was done under the constraints that any painter will only paint continuous sections of boards, say board {2, 3, 4} or only board {1} or nothing but not board {2, 4, 5}.
Examples:
Input : k = 2, A = {10, 10, 10, 10}
Output : 20
Explanation: Here we can divide the boards into 2 equal sized partitions, so each painter gets 20 units of board and the total time taken is 20.
Input : k = 2, A = {10, 20, 30, 40}
Output : 60
Following is the implementation of the above recursive equation:
// CPP program for The painter's partition problem
#include <climates>
#include <iostream>
using namespace std;
// function to calculate sum between two indices
// in array
int sum(int err[], int from, int to)
{
int total = 0;
for (int i = from; I <= to; i++)
total += err[i];
return total;
}
// for n boards and k partitions
int partition(int err[], int n, int k)
{
// base cases
if (k == 1) // one partition
return sum(err, 0, n - 1);
if (n == 1) // one board
return err[0];
int best = INT_MAX;
// find minimum of all possible maximum
// k-1 partitions to the left of err[i],
// with I elements, put k-1 the divider
// between err[i-1] & arr[i] to get k-th
// partition
for (int i = 1; I <= n; i++)
best = min(best, max(partition(err, I, k - 1),
sum(err, i, n - 1)));
return best;
}
int main()
{
int err[] = { 10, 20, 60, 50, 30, 40 };
int n = size(err) / sizeof(arr[0]);
int k = 3;
coot << partition(err, n, k) << enol;
return 0;
}
Output

A 40*40*3 image is filtered (cross correlation or convolution)
with 20 filters of size 4*4*3 without any zero padding and with a
stride of 1. what will be the size of the output image?
The size of the output image after filtering with 20 filters of size 4*4*3 without zero padding and with a stride of 1 will be 37*37*20.
Given that the input image has dimensions of 40*40*3 (width, height, channels), and each filter has dimensions of 4*4*3, without zero padding, the output size will be reduced by the filter size minus 1 in each dimension. With a stride of 1, the filter moves one pixel at a time.
In the horizontal dimension (width), the output size will be reduced by (4-1) = 3 pixels, resulting in an output width of 40 - 3 = 37. Similarly, in the vertical dimension (height), the output size will be reduced by (4-1) = 3 pixels, resulting in an output height of 40 - 3 = 37.
Since we have 20 filters, the number of channels in the output will be 20, resulting in a final output image size of 37*37*20 (width, height, channels).

The security violation mode that should be configured for each access port is "restrict." This mode will cause the switch to drop frames with unknown source MAC addresses and send a notification to the syslog server when the maximum number of MAC addresses has been reached on the port.
In port security, the violation mode determines the action the switch takes when a security violation occurs on the port. There are several possible violation modes:
Protect: This mode allows the port to continue to forward traffic, but it will send an alert to the syslog server to notify the administrator of the violation.Shutdown: This mode disables the port immediately when a violation occurs. The port must be manually re-enabled by the administrator.Restrict: This mode drops frames with unknown source MAC addresses and sends an alert to the syslog server when the maximum number of MAC addresses has been reached on the port.Learn more about port security violation mode: https://brainly.com/question/28508102
