Traditionally, computers are part of our daily life. Every computer consists of a Central Procession Unit (CPU) which is made up of tiny circuits of elements called Silicon Wafers.
Classical computers come in BITS, it is made out of pieces of silicon which can either be in the state of zero or one. We call it a ground state or excited state, and everything that is typed: words, numbers, and colors is translated into BITS where the data is processed and stored.
The result that is generated after applying the data in BITS, is performed on Silicon Wafers made up of semiconductor microchips. This is traditional computing.
