Computers work on the principal of

Options

A. Superconductivity
B. Digital logic
C. Magnetic confinement of plasma
D. Electromagnetic induction

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the principle on which computers operate.

2. **Evaluating the Options:**
- **Superconductivity:** This is a phenomenon where resistance in materials is reduced to zero. While interesting, it is not the principle that computers operate on.
- **Digital Logic:** This refers to the use of binary numbers (0s and 1s) to represent data and perform operations. This is indeed the fundamental principle behind computer operations.
- **Magnetic Confinement of Plasma:** This is related to nuclear fusion and is not applicable to computer operations.
- **Electromagnetic Induction:** This involves generating electricity through magnetic fields, but it is not the principle that governs the operation of computers.

3. **Identifying the Correct Answer:**
The correct answer is **Digital Logic**. Computers fundamentally operate using binary logic, where 0 represents an "off" state and 1 represents an "on" state.

4. **Conclusion:**
Therefore, the principle on which computers work is **Digital Logic**.
