Explain the concept of pipelining in digital circuits.

Pipelining is a technique used in digital circuits to increase throughput by dividing a process into multiple stages, each handled by different parts of the circuit simultaneously. By allowing multiple instructions to overlap in execution, pipelining improves the efficiency and speed of processing, as each stage completes part of the task in parallel with other stages. This technique is commonly used in CPUs and other high-speed digital systems to enhance performance.
