An expansive field of the IT industry, computer programming is also referred to as software engineering or software development. Computing devices have run programs and applications from their initial inception, and so software engineering is now very well developed. Without any programs to give them instructions, computers would be 'dumb' containers without a purpose. Programs are running in just about all the items of technology we now have in our homes. We might not always think of them as programs but that is what they are - even a DVD player has an operating-system which enables it to work effectively. Software is all around you - it's what enables you to setup a recording on your television set, & what's driving the navigation-menu on the DVD you're watching. When you enjoy a movie on DVD or Blu-ray, what's actually going on is a piece of a software program has pulled the 1s and 0s from the disc, & decrypted them at terrific speed into video-information.

Low level languages like C are employed by systems-programmers - the existing variation has advanced significantly since the first one and is in fact now a lot more accessible. Applications programmers operate in many different higher-level languages, - there are far too many to list all of them, but each of them will have their own unique list of instructions & rules - & may suit one task more readily than another. Corporate database software, for example, is often written in 'languages' that suit that environment, whereas video games are likely to be written in low-level 'languages' like C - since they must be able to run as fast as possible. If you are writing a database-application, then it does not matter if your display re-draws in a tenth of a second or a 100th of a second, whilst in video games, it matters a great deal. The actual main concern for a database friendly 'language' is that it provides capabilities that help to make life easier for the end user. Stripping everything possible away so that it can work faster would be defeating the object. You might compare it to the difference between a racing car & a family-estate. The estate-car provides family transport at the appropriate price & quality, but its not ever going to win a race! For the purposes of taking the kids from one place to another though, it ticks all the right boxes.

Being familiar with where it is you want to go is essential before starting this (or any other) technical certification course, so that you can plan the most efficient route. If you simply take on studying without taking a look at where you want to finally end up, you'll likely arrive & find you're in another position entirely! Programming & software accreditations aren't necessarily easy to understand, and if you don't select them with care it might look like you're stepping through a minefield! Our IT advisors can help clarify everything to suit your needs. A forty five minute discussion could save you thousands of pounds as well as sometimes years of inappropriate training!

Software engineering then, at it's simplest level, is merely telling an item of electronic equipment in a particular language how to do its job. Of course, this is a considerable over simplification. At the complexity of your 'Windows' desktop computer, you'll probably find up to 100 different programs that are running behind the scenes, all maintaining the system and allowing you to actually do things. In fact there are two different types of programs used in computers. We have the operating system software, that's low-level, & the 'applications' software. Microsoft 'Windows' is among the most well-known operating-systems of all. 'Windows' is an extremely sophisticated number of programs, all interacting with each other to control everything - the space on your desktop, how you interact with it, your internet & network access, all of the storage mediums & all of the connecting-devices.
