When a user hits a button on a web page the three layers including presentation layer, logic layer, and data layer, of the web application are being used.
For data processing the web applications are organized into three layers which are the presentation layer, the logic layer, and the data layer. Based on the given scenario in the question, all the three layers of the web application are being utilized when the user hits a button on a web page/web application.
The working of each layer of the web application upon hitting a button is as follows:
The presentation layer: It allows the user to hit the button. It provides an interface through which the user interacts with the web application by clicking a button. The user hits the button on the presentation layer.The logic layer: The presentation layer then communicates to the logic layer where the request generated by clicking the button is processed. For processing the request, the logic layer interacts with the data layer to acquire the data needed. After receiving the data, the logic layer processes it and sends it back up to the presentation layer to be displayed to the user. The function of the logic layer is to process the requested data.
The data layer: The data layer sends the required data to the logic layer for processing. The data layer stores and manages all the data associated with the application.

What is the trusted registry that guarantees the authenticity of client and server public keys?
The trustworthy registry that ensures the validity of client and server public keys is known as a certification authority.
In the realm of cryptography, a certificate authority, also referred to as a certification authority (CA), is a company that stores, signs, and offers digital certificates.
A digital certificate confirms the public key ownership of the certificate's stated subject. As a result, statements made about the private key that corresponds to the certified public key can be trusted by third parties (relying parties). A CA serves as a reliable third party who is respected by both the certificate's subject (owner) and the party using it.

What is the shortcoming of using mips or flops as a measure of system throughput?
There are a few potential shortcomings of using either MIPS or FLOPS as a measure of system throughput. For one, MIPS or FLOPS can be affected by a number of factors, such as processor speed, number of cores, and memory speed. This can make it difficult to compare two systems using MIPS or FLOPS as a metric.
Another potential issue is that MIPS or FLOPS numbers can be artificially inflated by compiler optimizations or other factors. This can lead to misleading results, and it's often difficult to determine whether or not a system's MIPS or FLOPS numbers are accurate.
Overall, MIPS and FLOPS are decent metrics for measuring system throughput, but they aren't perfect. There are a number of factors that can affect their accuracy, and it's important to keep this in mind when interpreting MIPS or FLOPS numbers.

In salivary conditioning, dogs will often orient toward the cs. This phenomenon is?
This phenomenon in the conditioning of saliva.
Classical conditioning is a behaviorist theory of learning. It posits that when a naturally occurring stimulus and an environmental stimulus are repeatedly paired, the environmental stimulus will eventually elicit a similar response to the natural stimulus. The most famous study related to classical conditioning is the experiments of the Russian physiologist Ivan Pavlov with dogs.
Type of Stimulus and Response
Each stimulus and response in classical conditioning are referred to by special terms which can be illustrated with reference to Pavlov's experiments.
Serving food to dogs is called an unconditioned stimulus (UCS) because the dog's response to food occurs naturally.The light or the bell is a conditioned stimulus (CS) because the dog must learn to associate it with the desired response.Saliva in response to food is called the unconditioned response (UCR) because it is an innate reflex.Saliva to a light or a bell is a conditioned response (CR) because the dog learns to associate that response with the conditioned stimulus.You can learn more about Classical conditioning here brainly.com/question/17583598

Which xxx and yyy will find the minimum value of all the elements in the array? choices are in the form xxx / yyy.
userVals[i][j] < minVal / minVal = userVals[i][j] XXX and YYY will find the minimum value of all the elements in the array Choices are in the form XXX / YYY.
int userVals[NUM_ROWS][NUM_COLS];
int minVal = userVals[0][0];
for (i = 0; i < NUM_ROWS; ++i) {
for (j = 0; j < NUM_COLS; ++j) {
if (XXX) {
YYY;
}
}
}
We often need to find the minimum value in an array of numbers. There are a few different ways to do this, but the most straightforward is to use a for loop.
We start by assuming that the first element in the array is the minimum. Then, we compare this value to every other element in the array. If we find a smaller number, we know that this is the new minimum.
Here's the code:
int userVals[NUM_ROWS][NUM_COLS];
int minVal = userVals[0][0];
for (i = 0; i < NUM_ROWS; ++i) {
for (j = 0; j < NUM_COLS; ++j) {
if (userVals[i][j] < minVal) {
minVal = userVals[i][j];
}
}
}
You can see that we're just looping through all the elements in the array and keeping track of the smallest number we've seen so far.

What is the output resistance of the two stage amplifier not including the 50 ohm load resistance?
As we know, the output resistance of an amplifier is the measure of the opposition to the flow of current at the output of the amplifier. In a two stage amplifier, the output resistance is the resistance of the second stage amplifier not including the 50 ohm load resistance. Therefore, the output resistance of the two stage amplifier not including the 50 ohm load resistance is the resistance of the second stage amplifier.
