What is a semaphore in programming?
A semaphore is a synchronization primitive used to control access to a common resource in concurrent programming.
How does a semaphore work?
A semaphore maintains a count that represents the number of available resources. Threads can increment or decrement this count to signal availability.
What are the types of semaphores?
There are two main types: binary semaphores (which can be 0 or 1) and counting semaphores (which can take any non-negative integer value).
Can you give an example of using a semaphore?
Sure! In a producer-consumer scenario, a counting semaphore can be used to limit the number of items in a buffer, ensuring that producers wait if the buffer is full.
