What is a semaphore in threading?
A semaphore is a synchronization primitive that controls access to a common resource in concurrent programming.
How does a semaphore work?
A semaphore uses counters to manage access; it allows a certain number of threads to access a resource simultaneously.
What is the difference between a binary semaphore and a counting semaphore?
A binary semaphore can only take values 0 or 1, while a counting semaphore can take any non-negative integer value.
Can you give me an example of using a semaphore?
Sure! In a print queue, a counting semaphore can limit the number of printers available, allowing multiple print jobs to be managed.
