Computer Programming, often called software development or engineering, is another extensive field of I.T.. The profession has been around & developing for as much time as computer systems themselves have been around. With no programs to instruct them, computers would just be inert boxes with no purpose. Virtually every piece of technological hardware in existence incorporates a program running it. We might not always think of them as programs but that's what they are - even your DVD-player contains an operating system which makes it possible for it to work properly. Consider the navigation-menu which pops up when you are watching a DVD - that's software, and so is the on-screen interface that you use to set the recording of a programme on your TV. Whenever you watch a film on DVD or Blu-ray, what's really going on is a bit of a software program has drawn the 1s and 0s from the disc, & de-crypted them at amazing speed into video information.

Several factors make it largely accepted that 'C' is the most useful language for the commercial programming student to commence with. The language is incredibly disciplined, and many more have developed from it. When you've mastered how to write programs in 'C', you'll find the change to others is much more spontaneous. Microsoft support C very heavily - its the key systems language, and is one of the major 'languages' in both Microsoft Visual-Studio and its collection of certifications. The knowledge that Microsoft promote it so eagerly, and provide an array of commercial accreditation in this 'language', is yet another reason why its worth-while going after it as a place to start. The first release of C was constructed in the 1960's, although it wasn't then named as such. The change over to object-oriented C++ (in other words the program is not just one, linear series of events - it may be multiple 'objects' communicating with each other) was done in the eighties. Around the turn of the century, Microsoft introduced a '.NET' enabled edition which came to be named C# (C Sharp,) leading us all to where we are today. MS developed a software-framework which allows 'Windows' programmers to have access to a wealth of pre-written libraries. This is what the term .NET identifies, & it helps to save programmers a great deal of time as so many of the elementary tasks have been done for them.

Programmers working on systems use languages such as C. The 'C' of today is a low level user friendly 'language' that hardly resembles the initial edition. Software engineers working on 'applications' use higher level 'languages', of which you can find a whole lot. Each one has it's own particular group of rules & commands, plus some are suited to particular tasks more than others. So database programs are almost certainly going to be written in an appropriate 'language' that fits the database-environment, but games programs require a low-level language (such as C) to work quickly enough. With database 'applications', split second timing isn't important, however with games 'applications' its very critical indeed! So, a database-oriented language gives you features designed to make your job a lot easier - instead of stripping everything out to make it operate faster. You might contrast it to the big difference between a racing car and a family estate. The family estate is a lot more comfortable and economical, but the trade-off is speed and handling. For long journeys with the kids though, the functional aspects are much more relevant.

Software engineering then, at it's lowest level, is actually telling a piece of electronic equipment in a certain 'language' how to do its job. Needless to say, this is a considerable over simplification. At the complexity of your 'Windows' desktop computer, you'll probably find as much as 100 individual programs that are running in the background, all maintaining the system and allowing you to actually do something. In essence, there are two levels of software programs for computers; the operating system (or low-level) software, and the 'applications' that run along with those systems. Among the most popular operating systems in the world is MS Windows. An entire suite of programs have to inter-act here to make your PC do anything you ask of it - from controlling your desktop space, to managing your interaction with it, to hooking you up to the internet or your network etc.

Just like with every other technical accreditation, a precise picture must be achieved on where it is you'd like to get to, to ensure the best path to that place can be worked out. Any time you really don't start with the end objective in mind, but merely subscribe to the most reasonable-looking course, chances are you'll wind up in the most inappropriate place altogether! The IT arena can feel quite complicated to an 'outsider', & software qualifications often just resemble a list of Acronyms! We'd suggest you discuss things with an experienced expert before you finalise your overall career-track. Please don't waste your time (& significant amounts of your cash) by passing up on this vital step.
