Understanding IT

Whether you’re in human resources or sales, the IT industry is growing and will most likely become an increasing part of your everyday work environment.

To help you navigate through the potentially confusing world of Information Technology, here is a list of some common IT terms and definitions explaining how businesses can make use of them. These terms can often be an obstacle when understanding the IT industry, but hopefully this list can help you begin to break through the barrier.


  • Database: a digital collection of data that is stored by a certain technique, similar to a file cabinet
