>コンピューターのＣＰＵはただの「ある」と「なし」の集合体。

電気回路上の「ある」と「なし」は、
ＯＮ/ＯＦＦというスイッチングを意味する。<

A computer works with numbers based on two. The reason for this is that it is easy to represent two states, using a voltage which is either on or off. Off is called ‘Logic Zero’(0) and On is called ‘Logic One’(1).

This ‘Base 2’ numbering system is called ‘Binary’. The smallest digit is the ‘Binary Digit’ or ‘Bit’.
