Programs are made out of information. When you write a program you’re putting information in a certain order to tell a computer what to do.

The early use for computers (apart from classified wartime codebreaking) was handling business information storage and retrieval. Previously large amounts of information were stored on card indexes which required large archives and teams to retrieve relevant cards in response to queries.

So this function was replaced by new technology for processing information – *Information Technology*. That department then diversified as computers changed, into what we see today. IT departments are still heavily engaged in ensuring secure data (information) storage, backups etc.

Sawmills usually focus on cutting wood rather than on saws themselves, but use a saw to do the job. Same goes for Information Technology – it uses information (software, user input, etc) to do whatever work you want it to.

What are applications in our modern time? They process information that you put into them. Almost every application needs to manage data. For a simple login system, you already need a username and a password saved in a database.

Applications that don’t rely on data are so primitive nowadays that you will have applications relying on data most of the time.

Applications have a major role, possibly even the biggest role in managing your information. You can’t think applications and computers away from this whole process.

I have a joint IT & Computing degree – the ‘computing’ component was strictly the programming, the IT part covered software and hardware technologies – networks, mobile communications, sensors, etc
