Understanding Logic Gates and Their Classification
Logic gates are fundamental building blocks in digital circuits, performing basic logical functions that are essential for processing binary information. The classification of these gates, along with their interconnections, is referred to as a logical network.

What is a Logical Network?
A logical network encompasses:
- **Interconnections of Logic Gates**: This refers to how different gates (AND, OR, NOT, etc.) are connected to form complex circuits.
- **Functionality**: It defines the overall behavior of the circuit based on the combination and arrangement of gates.
- **Circuit Design**: Engineers design logical networks to perform specific tasks in computing and digital electronics.

Why Option 'A' is Correct
- **Definition Alignment**: The term "logical network" specifically captures the essence of how logic gates are organized and function together.
- **Application**: Logical networks are utilized in various applications, from simple electronic devices to complex computer systems.
- **Contrast with Other Options**:
- *System network* generally refers to broader system-level connections, not limited to logic gates.
- *Circuit network* could imply physical connections but lacks the specificity of logical operations.
- *Gate network* could be misleading, as it may not encompass the logic behind the connections.

Conclusion
In conclusion, the classification of the number of logic gates and their interconnections as a "logical network" is fundamental to understanding digital electronics. This terminology emphasizes the logical functionality and design principles that govern how these gates work together to execute complex operations.
