    				| 1. | Why binary number code is used in computers? | 
| Answer» The term “binary” means “two”. Thus, the binary number system is a system of numbers based on two possible digits – 0 and 1. Each binary digit, or “bit”, is a single 0 or 1, which directly corresponds to a single “switch” in a circuit. Binary codes are used in computers because they are used to represent information in the digital world. | |
