Computer Programming, also referred to as software development or engineering, is another expansive field of I.T.. The profession has been out there and developing for as much time as computers themselves have been around. Without a software package, more or less all electronic devices would just be inert containers that didn't actually do anything. Programs are running in most of the bits of technological hardware we have in our possession. DVD or Blu-ray players for example have a thing known as 'firmware' which essentially is a simple operating system which allows the kit to work. Software is just about everywhere - it's what allows you to setup a recording on your television set, & what's driving the navigation-menu on the DVD or Blu-ray you are watching. The fact that you can see a motion picture when you press play on a DVD or Blu-ray player, is merely a function of a bit of software that pulls the 1s & 0s from a disc, and then de-crypts them straight into video 'information' at amazing speed.

The main Microsoft certification tracks were updated a short while ago, when they moved from the earlier 'MCAD'/'MCSD' (Microsoft Certified Application/Solutions Developer) to the more modern MCTS (Microsoft Certified Technology Specialist) & 'MCPD' (Microsoft Certified Professional Developer) exams. Look to study for 2 pre requisite 'MCTS' accreditations before getting into the 'MCPD'. If you're not used to the sector and haven't ever programmed before, (although the first unit from MS is called a foundation unit,) it would be wise to study a programming introductory course first. We'd equally recommend taking a support qualification prior to all of this, so as to obtain a decent understanding of software environments and support. This will likely in addition help with getting your first job in the I.T. industry. An entire career-track will require about 600 to 700 hrs of study time, so if you're training part time you should be able to do the whole thing within around twelve - eighteen months.

Low-level 'languages' like 'C' are employed by systems-programmers - the present version has advanced quite a bit since the first one and is in fact now far more accessible. Applications programmers work in many different higher-level 'languages', - there are too many to list them all, but they will each have their own list of rules and instructions - and may well suit one particular task more readily than another. Corporate database-software, for example, is often written in 'languages' suited to that particular environment, whilst video games are usually written in low level languages like 'C' - as they have to run as quick as possible. When you're creating a database application, then it does not matter if your display 're-draws' in one tenth of a second or a hundredth of a second, whereas with video games, it matters a great deal. We need capabilities that are built to make things easier for the database end-user, therefore a stripped-down language created for speed would be wholly in-appropriate. You could compare it to the difference between a racing-car and a family estate. The estate-car provides family travel at the appropriate price and quality, but it's not going to win a race! For a parents & kids on a long journey though, warmth, comfort & a smooth ride are a lot more relevant.

At it's simplest level then, you can say software engineering is basically telling electronic equipment how to do a task by use of special languages. Obviously, this is a considerable over-simplification. At the complexity of your 'Windows' desk-top computer, you'll probably find around 100 different programs that are running behind the scenes, all maintaining the system & allowing you to actually do things. Essentially, there's two levels of programs for computer systems; the operating-system (or low-level) software, & the applications that run along with those systems. Among the most popular operating systems globally is MS 'Windows'. This really is an enormously complicated selection of programs which interact with each other and control your desk-top space, how you interact with it, all the storage-mediums & network/internet access, together with all the devices which are connected to the Desktop.
