1.1.1 Binary systems – What are Binary digits?

Learning Objective(s):

• recognise the use of binary numbers in computer systems

Summary:

Human perceive information as an analogue signal whereas computers and machine perceive it as a digital signal.

The computer then needs to convert digital signals into analogue signals so that human can understand and vice versa.

Analogue data information is continuous, like temperature or time.

Digital data uses discrete values (0 and 1) also called binary digits and therefore are not as accurate as analogue datas.

In the next topic we will dig deeper in Bytes and what is it.
