Professional computer programmers are often called software engineers, or software developers. Computing devices have operated programs and applications ever since their very first release, and so software engineering is actually very mature. With no programs to give them instructions, computers would simply be inert boxes without a purpose. Programs are running most of the pieces of technology we have in our homes. Admittedly, much of this is what we call firmware, or a simple operating-system that allows the equipment to operate; video-recorders & DVD Players are examples of these. The on screen interface which you use to set up a Television recording, or the navigation menu which pops up when watching a DVD or Blu-ray is all software. As you click 'play' on your DVD recorder and settle-down to watch a film, an item of software pulls the binary-code off the disc & transforms it into video information incredibly quickly.

In its simplest format, a program will make use of a specific 'language' to tell electronic equipment exactly how to perform a task. As you may suppose, that massively over- simplifies the task. You'll probably find approximately one hundred distinctive programs working behind the scenes of your 'Windows' desktop-computer. They are what in fact enable you to perform tasks since they sustain the whole system. PC's effectively run on two different types of software program - the operating-system is low-level, & the 'applications' run by the operating system are higher level. 'Windows' from Microsoft is most likely the operating-system the majority of us know best. A complete suite of software programs need to interact here to ensure your PC does every little thing you require of it - from running your desktop space, to managing your interaction with it, to connecting you to the internet or to your network etc.

Programmers focusing on systems use languages such as C. The C of today is a low level easy to use 'language' that scarcely resembles the original release. Applications programmers work in a number of different higher-level 'languages', and there are far too many to name all of them, but each of them will have their own unique list of instructions & rules - and may well suit a particular task more than another. For example a software engineer writing database-software for corporate use would use a language suited to that environment, but a software engineer writing games-software would most likely use 'C', to obtain rapid running-speeds. It doesn't really make any difference if display screen changes take a couple of milli-seconds longer with database 'applications', however it matters a tremendous amount with games 'applications'. You need capabilities that are designed to make things easier for the database end-user, and so a stripped down language created for speed is extremely in-appropriate. You could contrast it to the difference between a racing-car & a family-estate. The family estate will be a lot more comfortable & easy on the pocket, but the trade off is speed and handling. To the parents & kids on a lengthy journey though, warmth, comfort & a smooth ride are a lot more important.

We are now experiencing a fast progressing trend in the direction of internet-based and network based software, as the concept of 'cloud computing' is starting to become a reality. This is a phrase meaning that all your data files are saved out in the ether, to allow them to be accessed from anywhere. All of the processes are done remotely - even the raw processing. Your only requirement eventually is going to be a very basic, slightly-dumb terminal that's plugged (or wirelessly connected) into the Network.

As with any other 'technical' certification, an exact goal needs to be worked out on where it is you want to get to, so that the right approach to that position can be worked out. If you don't start out with your goal in mind, but just sign up for what looks like the most reasonable looking program, it's possible you'll finish up in the wrong place altogether! Programming and software accreditations are not always straightforward, & if you don't choose them with care it might seem like you're walking through a minefield! Our industry advisors can help explain everything for you. Don't fritter away your time and energy (& a great deal of your cash) by ignoring this important stage.
