Use of Computers for Military Training

Computer Simulations

    Computer simulator were born around the same time as the computer game, but the concept of computer games took off much faster than military simulators. People all over the world wanted to get in on the PC gaming action. It wasn't until the military realized the potential of computer simulators did funding for simulators begin to pour in.

    Computer simulations allow the military to train soldiers for severe combat situations without actually having to put them in harm's way. The Air Force can train pilots in flight simulators long before they actually get in the cockpit. Computer simulations have become so advanced that computer games have begun to model themselves after combat and flight simulator software.

Communications

    The military without computers would be a far different place. Sure, we could use the tried and true method of Morse Code, but simply typing in a message an hitting 'send' is so much easier and faster, especially in actual combat situations.

    When it comes to training the military, being able to communicate easily among groups is the key to learning how to work together. Also, use of computers in communication allows those specializing in military communication to get hands-on training in a real world setting.

Military Testing

    Military schools depend on computers for testing the aptitude of the students. What's taught in the classroom setting is tested using computers in order to ensure the validity of the student's answers. Some of the aptitude tests are used to decide what the soldier's occupation will be during her service time.

Military Secrecy

    The many ways computers are used in the military is kept secretive. Many military programs and hardware is kept confidential for the purpose of national security. However, the military has confirmed that much of its training is computer- or technology.

Should I Become a Web Developer or Web Programmer?

What is a Web Programmer or Web Developer?:

A Web programmer or Web developer is the person in charge of making the website do things. They create the interactivity on the site including the actions on forms, rollovers for menus, and any Ajax or other programming on the site.


The following questions detail some of the common aspects of working as a Web developer or Web programmer for a company (not freelancing). The more of the questions that you can honestly answer "yes" to the more suited Web programmer is to you as a profession. Remember, however, that Web development is only one way to work on Web pages. There are also jobs as Web designers,Web producers, Web writers and graphic artists, and Web freelancers. You may be better suited to one of these professions.



Are you interested in the Web?:
Most Web programmers love the Web. They browse it a lot and love looking at other Web pages. While it's possible to do the work without enjoying the medium, if you don't like Web pages, eventually programming them will start to annoy you. If you aren't interested in the Web, then looking for a job as a Web programmer isn't a good idea.

Do you like to solve problems with computers?:

Web programmers are typically problem solvers. They prefer to make a Web page "work" than make it look pretty. If you find yourself thinking a lot about how to make a Web page do something, then you are well suited to be a Web programmer.

Are you willing to learn several Web languages?:

As a professional Web developer or Web programmer, you'll need to learn several different languages. The two most important are HTML and Javascript. But you will ultimately want to learn other languages as well for server-side scripting like:
  • PHP
  • ASP.Net
  • Java
  • And there are dozens of other languages you can learn

Are you willing to learn how to work with databases?:

More and more websites use a database on the back-end to serve pages, store content, and manage the site. Maintaining these databases is nearly always the responsibility of the Web developer or Web programmer.

Can you work well with other people?:

Most Web developers are a part of a team of people working on the website. If you don't like working with other people or want to do everything yourself, you should consider freelancing or working at a very small company. Otherwise, you'll almost certainly have to work with designers to create the look of the page, Web producers to manage the HTML and CSS, and Web writers and graphic artists for the content. You might have to fill some of these roles yourself, but most companies split these jobs to some extent.

Use of Computers in Research

Computers have changed the ways in which scientific research is compiled and analyzed. Scientists, engineers and researchers alike are able to compile vast amounts of data and leave it to the computer to work through the data while focusing on another area of the research project. This creates research results with fewer errors and better-engineered products.

Complex Data Analysis

Computers used in scientific research have the ability to analyze data in ways and at speeds not possible with the human eye. They are able to analyze percentages of materials present in a variety of compounds from soil samples to chemicals and even the air you breathe. Additionally, computers used in this manner can determine trends in data samples. For example, computer analysis of data in research could determine the temperature at which certain chemical compounds break down or the percentages of improvement patients show when administered a certain medication.

Solving Mathematical Equations

Scientific research often requires that complex mathematical equations be solved in order to determine if data is valid or if a certain structure of molecules will remain stable. Computers are integral to this calculation process since scientists can write software programs specifically to provide answers to such questions. This removes the element of human error, which can cost research institutions millions of dollars in fixing a product that was created with even the smallest amount of flawed data.

Prediction Modeling

Scientists and researchers are able to use computer programs to model how data might manifest itself in the future. This ability is useful in predicting climate patterns, simulating how engineered products might perform in the field, predicting the erosion rate of beaches and anticipating the absorption rate of medications in the body. Scientists and engineers are then able to adjust building strategies or chemical compositions of products to ensure safe operation and consumption.
