How Does Data, Computers and Programming Work?

As we’ve seen, data can be both analogue and digital. The smallest building block of digital data is bits—the famous 0s and 1s. A combination of eight bits is called a byte, which in turn can represent 256 different values.

All data you have on your computer is ultimately combinations of bits and, therefore, bytes as well. We use programming languages to give the computers logical instructions on how to use the data, in a way that is also understandable to us.

Now it's time to test what you remember about how data works ...
