Unit 14 Event Driven Research Paper

What feature may be utilized to see specific detail of an event and may also be useful for observing intermittent issues?

These programs detect when keystroke input is being directed to another location besides the currently targeted window. Most programs will send an alert when such activity is detected providing a means for early detection and removal before sensitive data is obtained.

1.19)Ans.The interrupts are used to indicate events like change in events or if any error occurs or freeing of resources or I/o

Mouse is an input and pointing device that allows the user to control the graphical user interface. Keyboard is an input device that allows the user to input data and give commands to the operating system by typing. Commonly, a keyboard contains all the alphabetical letters, numbers from 1 to 9 and punctuation

Input: An input is when a computer receives data from external hardware such as a mouse, keyboard

* There are numerous non-graphical applications that make use of event driven programs, an example of this is a smoke alarm: when it sense smoke and the density of smoke reaches a certain level, the alarm goes off. An event has taken place there; a smoke alarm is non-graphical application but it’s very useful for event driven programming.

4.1 What did the system do as an application control? That is, how did the system know that this was wrong?

Event driven programs are also used in non-graphical applications as well such as real life objects like DVD Player, Microwaves Oven and washing machine also in operating systems such as CMD, PowerShell and

As student who is very interested in debates and discussions. Therefore I hope to have an opportunity to discuss with students my age to understand the Toronto's issues that have to be fixed. I believe attending the Model City Hall event will give me a chance of showing my ideas on improving Toronto's pressing issues, and to do researches which will help me to learn more about our society. Overall, this event will help me to actually understand what's happening in our city. That's why I do not want to miss this amazing event since I always hope to find out more about the city I am living in, and what we should do to face the serious issues in our

“I am angry because of your behavior, and I can not make jokes with you.” my mom said, “I am not mean to you, I just want you to be as thin as you can. Guys all like thin girls, so I hope that you can show your beauty during your youth.”

This is way more than just pushing a button. From set up to shut down, children learn what it takes to make this run smoothly. Then they operate the system.

was to give efficient and flexible performance making it a versatile language that has found its place in a

In sequential programs, the program is under control The user must synchronize with the program:

It is the main entry point of program it is a graphical user interface class it’s GUI has three buttons which are for to log in as a manager, as a cashier or as a supervisor when any of these button is clicked an event handler is being called which asks for the id and verifies id from the database and allow access to the respective user the code for event handler is given below:

As the event based systems are susceptible to constant change based on the flow of events the add-ons which were already provided by the tool will be completely useless as the developer will have to write all the automation scripts from the scratch .Such as limitation takes away a Huge advantage which was provided by the HP Tool, Furthermore, now the organization will require to look for a developer with actual expertise in the programming language. Considering our second example where extension to existing software testing tools is provided in order to facilitate a testing automation functioning of event driven programming. With example of a Stock monitoring and financial data processing applications which are classic example of asynchronous distributed systems. The trading system will implement financial exchange protocol[10]. This protocol deals with the buyer requesting something and the server correspondingly responds. Here the buyer can order multiple and similarly cancel multiple orders. In this system in order to automate the test results a finite the test script is passed through various events of the software and is automatically modified code is passed to the next event based on actions which have occurred in its preceding event as shown in figures below. Hence, this working example helps us achieve automation in an asynchronous event based systems. In order to write the automation scripts using HP UFT is possible. As HP UFT allows
