Computer networking training is a must have for any professional in the IT (Information Technology) field today.  Networks are connecting almost everything we use in the computer world.  Printers are connected via networks, computers are networked together, we connect to servers the world over through the largest network in the world (the Internet).  Networking is the basis for some of the most revolutionary information sharing in the modern world.  Computer networking training can provide the skills and knowledge needed to set up, troubleshoot, and repair networking issues.  The technician who can successfully do this will be in great demand for some time to come.  Even the home office worker will benefit from obtaining computer networking training, as many home offices are now equipped with pre-installed network jacks and / or wireless network systems.

Computer networking training is just like any other kind of training.  You want to check out all of your options and available resources before signing the dotted line for any classes.  In the IT industry, any type of training courses that you take should be taught by certified instructors, and even the school should have some certification behind it.  It is important when evaluating computer networking training that you take both of these into account.  It won’t do you any good to take a class from an accredited school, only to be taught by someone who isn’t fully qualified to teach the class.  In fact, this could be a violation of the school’s accrediting agency’s requirements.  Likewise, if your computer network training is provided by a top-notch certified instructor, but the school isn’t accredited, then you will get a certificate of completing the course that is virtually useless.  Don’t waste your money if you’re not sure.

You will also want to make sure that the school provides an affiliation with an outside certification for you once you complete the computer networking training.  In the field of networking, the major players for certifications are CompTIA, Cisco, and Novell.  While there is some debate among the various governing agencies, a quick glance on the search engines seems to point towards an edge for Cisco’s certification and CompTIA’s Network + certification.  So why is your opportunity for certification so important when selecting computer networking training?  It is simple.  Certification is your means of proving you know what you say you know.  Without being certified, you are simply another voice on the IT landscape, drowned out amongst the crowds.

So, as we have seen, computer network training is a requirement for any individual who is serious about being a computer professional.  While the options may seem endless, the qualifications you need to look for are very specific, and should not be ignored.  A final consideration to make when evaluating your choice of training providers is, of course, the final cost.  This should include taking into account any discounted certification programs that are available at the end of the course.  Obtaining good computer networking training does not have to become a chore, but should benefit everyone involved in the end.

Many people will play computer games without any knowledge of how much work went into the game. True, a lot of thought and creativity had to be employed in order to make the game work, but the game also required a good deal of computer programming and knowledge of different computer programming languages in order to make the game not only feel real, but look attractive as well. There are many sides of computer game programming, so if you are interested in computer game programming and may want to take up courses in the future, take a look at this list.

The game physics programmer is someone who directs how a game uses physics in order to look correct and feel correct. In most cases, a computer game will not completely simulate the physics of a real world, but some important aspects of physics may have to come into play for some games. For instance, wind resistance might be important to dogfights, while the fluid but retarded movements of some characters in water might be needed for a role-playing game.

The artificial intelligence programmer is the one in charge of developing the logical sequence of the game itself. For instance, when a game involves finding a path, employing strategies, or giving rise to enemy tactics, an artificial intelligence programmer may be called in to make a game smart – in other words, to make the game think on its own. In general, the computer language used for artificial intelligence programming is simpler than other languages, and it can be shared with the game’s players.

The graphics programmer uses a series of codes and algorithms in order to provide graphics in the world of the game. In the modern age, a graphics programmer has to work in a three-dimensional environment, and should therefore have knowledge of calculus, vector math, and other algebra concepts that may be needed for specializing in rendering such images. There are only very few graphics programmers, and they may usually demand high wages for their work.

A sound programmer will provide sounds in terms of characters’ dialogues, music, and even sounds that can make the game seem more real, such as the sound of crunching leaves or grass as characters walk on them. The gameplay programmer will add to the experience of the game, and will do so by focusing on the game’s feel and strategy.

Computer game programming will also require a team of scripters, who are also usually the designers of the game. These scripters write the code of the game itself, usually with a basic computer language. Also needed are user interface programmers, or the UI: the UI programmers will create a library of different aspects that can be used across a wide variety of worlds within the game, or a wide variety of games within a manufacturer. The UI programming language involves a good deal of math, with the aim of producing special effects.

Also important is an input programmer, who writes codes for how different kinds of hardware, such as the keyboard, joystick, or mouse, will affect the game. The network programmer will find ways for the game to work on a network, where people can play against each other. A porting programmer ensures that the game can work on different platforms and operating systems.

Overseeing all these tasks is the lead game programmer. These are only a few aspects of computer game programming. As the field widens, more and more programmers of different kinds will have to be called in and identified as important.

While Burning and Dodging are listed as tools in most photo editing software, they are digital versions of techniques originally developed by darkroom photographers years ago.

Burning is a trick for getting more detail out of a section of a picture.  The photographer makes his print normally, and then masks off a large section of the print, usually with his hands.  Then, with the light blocked, he adds a bit more exposure time to the print, so that the area that wasn’t masked gets more exposure.  Dodging, on the other hand, involves using a small piece of paper or cardboard to block the light from a section of the photograph.

Burning, then, means adding extra exposure to some element of the picture, while dodging is less exposure.  In general, this is different from the Brightness of a picture because brightness is applied to the entire picture, while burning and dodging are only applied to areas of the picture.

Photoshop, as an example, offers tools for Burning and Dodging.  You can adjust the size of the “brush” and apply it to any part of the image, and the program will lighten or darken the area, just like a classic burn or dodge would have.

Both techniques are used for “balancing out” a picture.  For example, if a landscape or cityscape turns out perfectly, but the sky behind it is overexposed (looking like a big white blob rather than the normal blue and white of sky and clouds), then dodging the sky will reduce the exposure, and hopefully bring the color back down to a normal level.  If the sky exposed in the perfect shade of blue, but the windows are too dark to stand out from the buildings, then burning the windows would help to expose them better, bringing out more detail and clarity.
