How Does a Computer Count?

Now back to the computer, which is essentially a dumb pile of matter: the materials (chemical substances) from which the computer is built can, if correctly arranged and connected, distinguish between 2 events: a relatively low electric current and a relatively high electric current that flows through those materials. [The power/pressure of a current is called voltage.]

Engineers, who realized this rather simple ability of these substances, took advantage of this fact to build up complex connections/links using these chemical substances to represent, calculate, and store data.

Fun question: According to the above, what number does a computer use as a base for counting?

In Topic 3: Boolean Algebra & Logic Gates, when we discuss the Transistor device, we will explain what chemical substances it is built of, how much low is a 'low' current and how much high is a 'high' current, and how exactly a Transistor would behave in the case of being subject to a low electric current vs. a high electric current (and how we can use it to build a computer.)
