Why does Computer understand only binary?





Q.  Why does Computer understand only binary?

In computer system all working mechanism depends on switch ON and OFF techniques to read/write data. A SWITCH ON is corresponding to 1 and OFF corresponding O. In this fashion, all data are stored in memory. Input data is converted into digital signals and passes from component to component, and in storing devices (memory or register) it is converted into binary or machine codes.

Example:

Suppose, we have to write BIKAS, it is heeded 5 byte to store it. When we press letters BIKAS, these letters are converted into digital signals and send to memory through bus, where converted into binary numbers. In main memory, flip-flops are used to make storage cells, cells use ON and OFF technique to store binary.

Memory cells are used to store data and when data is flashed out, next data is stored. We see that memory cells are used again and again to store data in binary fashion.

If it will store decimal, the sizes of memory will not be less than room and its portability can be terminated.
