Concept
An Interrupt Service Routine (ISR) is a special block of code associated with a specific interrupt condition, allowing a system to respond immediately to external or internal events, often in real-time. It temporarily halts the main program execution, executes the necessary response, and then resumes the main program, ensuring efficient and prompt handling of critical tasks.

Concept
The refractory period is a brief time after an action potential during which a neuron is unable to fire another action potential, ensuring unidirectional propagation of nerve impulses. It is divided into the absolute refractory period, where no new action potential can be initiated, and the relative refractory period, where a stronger-than-usual stimulus is needed to elicit a response.
