IT Career Outlines & Job Role Descriptions

Network Engineers, Technicians, PC Support, Security etc.

This is a very broad field in IT with many different job roles and types. It covers a range of jobs from the local technician at PC World, to the international systems architect flying all over the globe. From helpdesk roles, resolving individuals problems, to designing security systems for major financial institutions, as well as implementing & managing major digital communication systems.

In essence, these are the people that keep IT's wheels turning; they are the trouble-shooters, problem-solvers, designers and maintainers of the industry. With the ever-increasing worldwide dependency on IT, these positions have become essential to every company that uses computers. When a systems fails or stops working, it could potentially be very expensive in terms of lost business or revenue.

Therefore, individuals with the ability to diagnose and repair these problems, as well as provide preventative support and increased security, have enormous value.

Creative Web Design, Development & E-Commerce

Web designers and developers are responsible for all the sites that we look at on the Internet and World Wide Web. The designers are responsible for the look, feel and content of the sites, including how easy it is to find what you want. The managers are responsible for running the sites, administering the 'servers' (big computers where the site information is stored) and keeping them working effectively. Developers tend to work on the more technical database-driven, dynamic web-sites and information systems.

A good or bad website can make or break a company. If a website is well put together, easy to use, intuitive and lots of people can find it, then it has the capacity to be successful. More and more business these days is done via the internet. With the current escalation in technology and speed, it is likely that if a company is not on the internet, it will ultimately not be able to compete.

'E-Commerce' is a term that is often used to describe the way business is done on the web. SEO, or 'Search Engine Optimisation, and 'SEM', or 'Search Engine Marketing', are fast becoming some of the most important areas in E-Commerce. These are the studies of how the main search engines (like Google & Bing) store and 'rank' a sites information, together with advertising and marketing options. Obviously, every company wants it's site to appear at the top of the list!

Computer Programming & Software Development

A Programmer writes computer programs or software, often referred to as 'applications'. A Program is a very detailed set of instructions to enable your computer to perform a particular function. Some examples of programs could be anything from your Windows operating system, to word processors, spreadsheets, databases or games. This could also include the till systems at your local supermarket, the instructions for the robots that built your car, or the internet booking system that allows you to book your holiday on-line. Programmers use many different 'languages' (like 'VB', 'C++', 'PHP' & 'Java' for instance) which are tailored to suit particular needs or requirements.

Without programs, computers would just be dumb pieces of hardware; a useless box that does nothing. It is the creation of programs, operating systems and software that has caused the entire IT revolution. Obviously, their importance to a company and to society is profound.

Database Administration & Development

The reason we are now in the information age is because of databases. Databases can be huge stores of information and details which, because of their size and complexity, can far outstrip any humans ability to compile, analyse and evaluate that information.

Examples of databases are all the information stored by your bank, credit card companies, electoral register, census information and supermarket loyalty cards. (That's how they know to send you vouchers for cut-price dog-food. It's because you've bought dog food before, so they presume you have one!)

Most large companies and organisations are dependent in some form or another on databases. It's the recording and interpretation of all this information that enables senior managers to direct and manage their organisation effectively.
