What Technologies is Data Dependent On?

We’ve always had data—just not in the form of 0s and 1s. We've mentioned many examples—from sound waves on analogue media to parish registers in handwritten form. Digital data has existed for many decades, but date does not depend on digital storage.

Recently though, everything and everyone has been connected through the same networks. This is the driving force of the digital transformation. Networks are prerequisites for the type of data usage and data sharing we see today. Therefore, in this section, we will become more familiar with networks, the Internet, and protocols.

In this section, you will learn about the history of the Internet and how it works—and what's hiding behind acronyms like TCP/IP and HTML.

You’ll also get some insight into cloud computing.

Although we’ve had the Internet for quite some time (it actually dates back to the 1960s), it's only in the last couple of decades that cloud computing has become such an important piece in the digital puzzle. It is also a central part of the data infrastructure, and that is why we will take a look at what the cloud is and how it works.
