Specialist computer-programmers are often called software engineers, or software developers. Programming has, of necessity, been around as long as the the computers that operate those programs. Without a software program, more or less all electronics would just be dumb containers which did nothing. Programs are running most of the pieces of technological hardware we've got in our possession. Admittedly, a lot of it is what we call 'firmware' or a basic operating-system that allows the equipment to function; video recorders and DVD Players are examples of these. The on-screen interface which you use to set-up a Television recording, or the Navigation Menu that appears when viewing a DVD or Blu-ray is all software. The fact that you can see a movie whenever you press play on a DVD or Blu-ray player, is just a functionality of a bit of software that pulls the 1s and 0s off a disc, & then decrypts them into video information at incredible speed.

Software engineers implementing systems use 'languages' like 'C'. The 'C' right now is a low-level user-friendly language which scarcely resembles the initial release. Software engineers engaged on 'applications' use higher-level languages, of which you can find a good deal. Each one has it's own unique list of commands & rules, plus some are suited to particular tasks above others. Corporate database software, for instance, is commonly written in 'languages' that suit that environment, whilst video games are likely to be written in low level languages like C - simply because they have to run as quick as they can. It doesn't really make a difference if screen changes take a couple of milliseconds longer with database applications, however it matters a whole lot with video games applications. We need capabilities that are intended to make life easier for the database-user, consequently a stripped down 'language' for speed is wholly in-appropriate. You might compare it to the difference between a racing-car and a family-estate. The 5 - 7 seater estate is more comfortable & practical, but it's definitely not designed for speed. When taking lengthy trips with the children though, the practical features are much more relevant.

At its simplest level then, we could say software engineering is basically telling an electronic device how to do its job by use of certain languages. As you might imagine, that greatly over simplifies the task. There are probably approximately a hundred distinctive programs working behind the scenes of your Windows desktop computer. They are what actually allow you to perform tasks as they sustain the whole system. PCs in essence run on 2 separate levels of software program - the operating-system is low level, and the applications run by the operating system are higher-level. 'Windows' from Microsoft is more than likely the operating-system many of us are familiar with. 'Windows' is a very sophisticated number of programs, all inter-acting together to control everything - the space on the desk-top, how you inter-act with it, your internet & network access, all the storage mediums and all of the connecting devices.

Recognising where you want to reach is essential before beginning this (or any other) technical certification program, to be able to prepare the best path. If you simply undertake training without focusing on exactly where you want to end up, you'll likely get there & discover you're in another position entirely! Software accreditation really isn't the most straightforward certification to comprehend, & the I.T. industry can be a bit of a mine-field should you not select correctly, so we suggest that you speak with a professional industry expert prior to signing your name to any programs or expenditure. Do not fritter away your time (& significant amounts of your cash) by missing this important stage.
