What is a race condition?

can it occur under parallel execution or concurrent execution?

Solution

A race condition is an undesirable situation that occurs when a device or systemattempts to perform two or more operations at the same time, but because of the nature of the device or system, the operations must be done in the proper sequence to be done correctly.

A simple example of a race condition is a light switch. In some homes there are multiple light switches connected to a common ceiling light. When these types of circuits are used, the switch position becomes irrelevant. If the light is on, moving either switch from its current position turns the light off. Similarly, if the light is off, then moving either switch from its current position turns the light on. With that in mind, imagine what might happen if two people tried to turn on the light using two different switches at exactly the same time. One instruction might cancel the other or the two actions might trip the circuit breaker.

Yeah it can occur in concurrent execution
