What is the primary difference between combinational and sequential logic circuits?
Understand the Problem
The question asks to identify the key distinguishing feature between two fundamental types of digital circuits: combinational and sequential. Understanding the presence or absence of memory and its impact on circuit behavior is crucial for answering correctly. We need to choose the option that accurately describes this primary difference.
Answer
Sequential circuits have memory, while combinational circuits do not.
The primary difference is that sequential logic circuits have memory elements, allowing them to consider past inputs and states, whereas combinational logic circuits do not have memory and only rely on current inputs to produce an output.

The primary difference is that sequential logic circuits have memory elements, allowing them to consider past inputs and states, whereas combinational logic circuits do not have memory and only rely on current inputs to produce an output.
More Information
Combinational circuits are generally faster and simpler, while sequential circuits are capable of handling more complex tasks that require considering history.
Tips
A common mistake is to think sequential circuits are simply 'more complex' combinational circuits; understanding the fundamental difference of memory is key.
