Computers are based on…………

Answer

**Step-by-Step Solution:**

1. **Understanding the Basis of Computers**:
- Computers operate based on a system of logic that allows them to process information. This system is known as digital logic.

2. **Digital Logic**:
- Digital logic refers to the use of binary numbers to represent data. In this system, information is encoded in binary form, which consists of only two digits: 0 and 1.

3. **Binary System**:
- The binary system is fundamental to computer operations. It is a base-2 numeral system, meaning it uses two symbols (0 and 1) to represent all possible values.

4. **Representation of States**:
- In the context of computers, the digit '0' typically represents an "off" state, while '1' represents an "on" state. This binary representation allows computers to perform complex calculations and operations.

5. **Signal Transmission**:
- When data is sent to a computer, it is transmitted as a combination of these binary digits (bits). For instance, the number 2 in binary is represented as '10', and the number 3 is represented as '11'.

6. **Conclusion**:
- Therefore, we conclude that computers are fundamentally based on digital logic, which utilizes the binary system for processing and storing information.
