Big data is vast, unwieldy information that is so huge that normal software traditionally used to analyse it just can't cope.

It's not new. Ever since humans organised ourselves, we've been keeping records, and gathering information, from scrolls, to bank ledgers and now your internet browsing history.

But his information is now flowing into organisations at a faster rate and in greater volume than ever before. Taking a good look at it could provide meaningful insights. But how can you spot patterns in the chaos, without the job taking forever? And what insights could this mega data analysis provide?

Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree. This series is your chance to get back to basics and really understand key technology terms. What's an algorithm? where is "the Cloud" and what exactly is Blockchain? What's the difference between machine and deep learning in artificial intelligence, and is it just our jobs under threat, or is it much worse than that? And before we get to the destruction of humanity, should we all be using Bitcoin? Our experts will explain in the very simplest terms everything you need to know about the tech that underpins your day. We'll explore the rich history of how all these systems developed, and where they may be going next.
