It is claimed that the following is a correct analogy of the function of a semaphore used in inter-process communications: You are driving an electric car and after some mileage the electric car requires you to charge it. You look around and find a charging station that has four empty charging stations. The number of available charging stations are analogous to a thread, as it allows the access to a resource and the cars are analogous to semaphores as they are tapping into a resource.

Do you agree with this analogy? Why / why not?
