Show Answer

Answer:

Correct Answer: A

Solution:

  • Binary numbers are closely related to digital electronics. With digital electronics, a 1 means that current is present and a ‘-’ means it is not present. The different parts of a computer communicate through pulses of current (Is and Os). Computers can calculate complex equations and perform complex calculations. Calculating using only 1s and 0 s is called Binary system. A computer can process only 1s and 0 s.
