General Concepts about Object-Oriented Programming

The programming style that we usually call object-oriented programming (OOP) has appeared relatively recently in the history of programming languages. This is a particular and very convenient style for many situations. It was designed to overcome the limits of structured programming based mainly on the widespread use of procedures, functions, pointers or other more or less developed data types.

Although structured programming is very practical for small software systems or reduced non-graphic applications, it should be avoided when dealing with large applications that use graphic elements where object-oriented programming is recommended. Object orientation means organizing software resources as a collection of distinct and discrete objects, which includes both data structures and their processing functions. This organization is an extension of structured programming in which the data structures and processing functions are only loosely connected. All items have their own identity and are perfectly distinct.

An object is defined as an abstract concept, a specific and useful element for any application. Objects serve two specific purposes:

– they provide a better understanding of the problem to be solved;

– they provide a base design for implementation.

A class of objects encapsulates a certain number of objects with similar properties. This similarity refers to both the description (data and attributes) and the behavior (functions or methods). Attributes are unique features within an object class. Each attribute receives a certain value which can be modified during the objects life cycle. Two or more objects can have the same or different values for the same attribute.

Methods or operations are processing functions applied to objects of a certain class. All objects within a class admit the same set of methods, methods which in return may receive any number of additional parameters. In order to apply various methods to an object, it has to be created (defined). Defining an object is called instantiation. Once an object has fulfilled its mission it is removed.

Abstraction is a fundamental human trait that allows us to build models and thus cope with complexity. In every field of human activity, project approach is based on building a model for a better understanding of the problem to solve. Software engineering makes no exception. Through abstraction the essential key aspects are isolated from the non-essential ones. Therefore, each problem might have several adequate models.

In the software engineering industry, structured programming has made a big step forward defining three perspectives needed in order to properly address any application. These perspectives, also known as models, are: the static model, the dynamic model and the functional model.

There are currently several object-oriented methodologies used for analysis, design and implementation of software resources. One of these modeling methodology is the OMT (Object Modeling Technique) methodology. This method of modeling involves the planning of the various development stages and a graphical representation of objects and their relationships.

The Importance Of Computer Literacy In The Workforce

Computers are powerful machines that the world has ever known. Its power goes further since computers are not just for scientists or for engineers anymore. The computer systems and programs have reached a certain level of power that every person who is computer literate can acquire. Hence, computer literacy has become an essential part of developing a person’s individuality. Though sometimes you can not identify people who are computer literate, you know that they are just everywhere.

Computer Literacy and its Influence in the Workforce

To test a person’s level of being a technology-savvy is an imperative to many organizations and companies. In fact, computer literacy has become a fact of life since it can be attributed to a person’s education, lifestyle, and work.

Therefore, in order to advance to their career, people spend most of their time acquiring computer knowledge and education to become computer literate eventually. This is true because computer skills are essential skills that business people find from their employees or from their work force.

With the influence and essentiality of becoming a computer literate, it seems that living without computer skills would be unimaginable already. People rely too much on what people can do if they are computer literate. And they attribute the success of a particular business with the workforce that is computer literate.

The Benefits of Computer Literacy

1. Apparently, computer literacy in the work force increases business productivity. This is why, to make yourself marketable, you should at least have the basic skills in conducting jobs using computers such as reports, documentation, and more.

2. Computer literacy develops valuable workers especially if you focus to higher computer skills such as programming, hardware maintenance, database management, network administration, program development and many more related skills.

Automated Robots And Systems

With the advance of technology, it is now possible to trade the Forex market automatically. This is possible through the use of automated robots and systems that execute trades on behalf of a trader when a certain set criteria are achieved. A Forex robot is a program that strictly uses technical signals to execute trades in the trading platform without the direct intervention of the trader.

Although automated robots are a good way of navigating the Forex market, they have several pitfalls. The Forex market is very dynamic in nature; that is, the market conditions change on a constant basis. Therefore, since robots basically trade on a certain set of pre-wired conditions, they are not able to cope with the ever-changing conditions present in the Forex market.
A majority of the robots available out there are not programmed for all environments or are not able to recognize drastic changes in the market conditions. Therefore, they are prone at making losses, which can be enormous if not properly watched or managed.

Because of the advantages of trading using robots, scammers sometimes dig around these to give false claims to ill-advised traders. For example, a flashy advert can claim that a robot being sold at $30 is able to make 200-500 pips per day. While this is not impossible, you should be careful about such claims. If the robot is able to make such a huge number of pips per day, why cant the owner simply trade using it and make lots of money instead of trying to sell it to other traders?

It is important to note that in the world of Forex trading, there is no such thing as a consistent market, and past results are usually not indicative of future results. Conditions of the Forex market change on a constant basis. This means that results realized yesterday may not be the same results realized today. And, some of these scammers make up the results of their trades to convince traders to purchase their products. When the deal is too good, wont you think twice?

The most appropriate thing to do is to stay away from automated systems and robots until you have thoroughly fine-tuned your skills in trading. Beginners usually do not know anything on how the Forex market operates. Therefore, it is best to become a master trader before allowing automated robots and systems to do it for you.

Why Are Teens So Stressed Science Fair Projects

The topic of your science fair project is critical to its success. If you select a topic that you are not interested in you will find the process of completing a science fair project boring and tedious. However, you can overcome this problem by focusing on something that either interests you or that impacts your life directly. Here is a topic for this year’s science fair project “why are teens so stressed?”

Background Research

“Why are teens so stress?” This is the topic for your science fair project this year. So now that you have a topic your next step is to conduct research on this subject. This research will need to begin with a general search of teen stress. The results from this search will provide you with leads on what is stressing out teens and what research has already been done.

Develop a Hypothesis

Now that you know a little bit about your topic your next step is to develop a hypothesis. Your hypothesis will predict what is stressing out teens. For example, your hypothesis may be that teen stress rates are impacted directly by the stricter entrance requirements for college.

Develop an Experiment

After you have a hypothesis you will need to find a way to test that hypothesis. If your hypothesis is that teens are stressed by the increase in acceptance standards of colleges then you will need to design an experiment that tests how these higher standards are impacting student stress levels. You can do this by collecting data on college entrance requirements from the 70s and comparing them to those of today, and you can also conduct interviews with teens to figure out how stricter college entrance requirements are impacting their stress levels.

Collect Data

Data collection for this type of science fair project will involve collecting data and information from government and nonprofit sources, as well as collecting data directly from your own test subjects. When you are collecting data from your test subjects make sure your test conditions remain constant for each experiment. This will help to ensure your data is reliable and valid.

Computer Science Curriculum

If you want to get a BS degree in computer science, you will need to complete approximately four years of schoolingthe same as for any bachelors degree. There are different types of schools that offer these computer degrees, ranging from online schools to technical schools to traditional campus-based universities. Whether you choose a traditional four-year college or an alternative program, your information technology coursework will include most of the same materials.

There are different types of schools that offer these computer degrees, ranging from online schools to technical schools to traditional campus-based universities. Whether you choose a traditional four-year college or an alternative program, your information technology coursework will include most of the same materials.

When you begin a computer science program, the first semester or two will be spent on the basic introductory courses. This might include computer history, basic terminology, and some other science-related course like calculus and chemistry. This is the point that students often decide which direction they want to take their computer science degree, which could range from programming to networking to computer repair and building. Programming is probably the most popular choice these days, though.

Once you have finished the basic courses and decide on the area you want to specialize in, you can start taking more specific courses. If you want to go into programming, for example, you can start taking fundamental courses in BASIC, FORTRAN and COBOL before more advanced courses on topics such as programming languages like C++ and PASCAL. Or, if you want to go into networking, you will begin taking courses that concentrate on networking systems like Novell and Microsoft Networks.

In most cases, a bachelors degree in computer science or information will involve some sort of final project. The computer and information technology program curriculum may vary from one school to the next, however, and it will also vary greatly depending on the degree you are going after. If you are getting a certificate or an associates degree, you might just focus on one very specific area or get a more basic overview of things. And, if you are getting a masters degree, the learning will be much more in-depth for your specific area of specialization. You can learn more about the program curriculum at various schools by visiting their web sites or speaking to a counselor there.
