identify a recent personal user experience where it either was very clear or very unclear about what the sequence of steps was necessary to complete a task:-
designer will consider the Why, What and How of product use. The Why involves the users’ motivations for adopting a product, whether they relate to a task they wish to perform with it, or to values and views associated with the ownership and use of the product. The What addresses the things people can do with a product—its functionality. Finally, the How relates to the design of functionality in an accessible and aesthetically pleasant way. UX designers start with the Why before determining the What and then, finally, the How in order to create products that users can form meaningful experiences with. In software designs, designers must ensure the product’s “substance” comes through an existing device and offers a seamless, fluid experience.
Design goals help us stay focused on what we've determined to be most important in a project. They can serve as a quality check by making sure the designs meet the intended goals. These are typically at a high level and can be thought of as driving principles for a particular project. These can be thought of as related to if not the same as the benefits described in the problem statement. The design goals are likely fuzzy at the beginning of the project. The goals should be revisited and iterated on early and often.
this things user should be clear about:-
Don't change the display of information between editing and displaying edited information (i.e. wysiwyg).
Don't require user to leave or change their context to edit information.
Make it clear that changes can be made and to what.
Give users edit tools that make sense for their specific context. Don't clutter with every possible edit tool.
Smooth & easy keyboard interaction.
Allow users to easily see and use the edit tools they need (as opposed to giving them many tools that aren't relevant or useful most of the time).
Give users feedback and confidence about what is saved.
Give users an easy way to back out (i.e. undo change & error recovery).
Instant editing
Allow user to complete their task without being distracted by software or losing train of thought (i.e. while they are reading text they can easily make a quick edit).
Give users access to information they need to complete their task (i.e. information on other pages, etc.).
Assist users in not making mistakes with their edits. If mistakes are made, we need to give them an easy way to identify and correct.
What made that experience memorable:-
this things makes experience memorable
1. Make an Impression
2. Tell a Story
3. Use Color Effectively
4. Do Something Fun
5. Engage the Senses
6. Mix It Up
7. Remember the Finish
b) source address
c) type of application
The most significant protocol at layer 3, often known as the network layer, is the Internet Protocol, or IP.The IP protocol, the industry standard for packet routing among interconnected networks, is the source of the Internet's name. Thus, option C is correct.
Application-layer firewalls operate at the TCP/IP stack's application level (all browser traffic, or all telnet or ftp traffic, for example), and thus have the ability to intercept any packets going to or from an application. They stop different packets (usually dropping them without acknowledgment to the sender).
Firewalls are frequently positioned at a network's edge. An external interface is the one that is located outside the network, while an internal interface is the one that is located inside the firewall.
Therefore, The terms “unprotected” and “protected,” respectively, are sometimes used to describe these two interfaces.

The answer is c) type of application
one of the 4 vs of big data that refers to uncertainty due to data inconsistency and incompleteness, ambiguities, latency, deception, and model approximations is veracity.
Conformity with truth or fact : accuracy. : devotion to the truth : truthfulness. 3. /vəˈraes.ə.ti/ the quality of being true, honest, or accurate: Doubts were cast on the veracity of her alibi. Synonyms. Veracity is the quality of being true or the habit of telling the truth. He was shocked to find his veracity questioned. Veracity refers to the quality of the data that is being analyzed. High veracity data has many records that are valuable to analyze and that contribute in a meaningful way to the overall results. Low veracity data, on the other hand, contains a high percentage of meaningless data. This type of source is the starting point for any historian-researcher. Some written sources are forgeries.

Answer:
192.168.228.0 255.255.255.224
Explanation:
192.168.228.0 255.255.255.128
subnet mask: defines the host and the network part of a ip
CIDR notation : is the shortened form for subnet mask that uses the number of host bits for defining the host and the network part of a ip
For example: 192.168.228.0 255.255.255.128 has CIDR equivalent of 192.168.228.0\25
To have atleast 20 hosts
20 ≤ (2^x) -2
x ≈5
with 5 host bits, we have 2^5-2 = 30 hosts per subnet
and 2^3 = 8 subnets
To get the subnet mask, we have 3 network bits
1110000 to base 10 = 2^7 + 2^6 +2^5= 224
192.168.228.0 255.255.255.224
Answer:
Abstraction refines concepts to their core values, stripping away ideas to the fundamentals of the abstract idea. It leaves the common details of an idea. Abstractions make it easier to understand code because it concentrates on core features/actions and not on the small details.
This is only to be used for studying purposes.
Hope it helps!
(B) Man-in-the-middle attack
(C) Smurf attack
(D) Format string attack
(E) Denial of service attack
Answer:D)Format string attack
Explanation:
Format string attack is the type of attack that causes to change the application functioning .This attack access the memory of the string library. It occurs while the submission of the string as input and then gets tested due to application command.
Other options are incorrect because these are the attacks that don't happens in the application for the alteration of the flow. Thus, the correct option is option(D).
Create a pane using FlowPane in each stage
Add three buttons to each pane
Directions
Create a class named FlowPaneDemo extends Application
Create user interface using FlowPane
Add the instances of 3 Buttons to pane1 created by FlowPane and other 3 instances of Buttons using FlowPane to pane2
Create scene1 for pane1 with a specific size and scene2 for pane2 with a different size
Set different titles to two stages and display two stages
The output should look like the screen below
Provide appropriate Java comments
Answer:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.FlowPane;
import javafx.stage.Stage;
import javafx.scene.control.Button;

Button buttonTwo = new Button("Button Two");
Button buttonThree = new Button("Button Three");

//Adds the Buttons to the two FlowPanes.
paneOne.getChildren().add(buttonOne);

//Creates two Scenes, using each of the FlowPanes.
Scene sceneOne = new Scene(paneOne, 250, 600);
Scene sceneTwo = new Scene(paneTwo, 320, 400);
//Makes a second Stage.
Stage secondaryStage = new Stage();
//Set the title and Scenes for the two Stages.
primaryStage.setTitle("First Stage");
primaryStage.setScene(sceneOne);
secondaryStage.setTitle("Second Stage");
secondaryStage.setScene(sceneTwo);
//Runs the show methods for the two Stages.
primaryStage.show();
secondaryStage.show();
}
public static void main(String[] args){
//Runs the launch method to start a stand-alone JavaFX application; only needed
//as I am running this in Eclipse.
