👉 Semaphores, also known as locks or pipes, are a fundamental concept in computer systems that allow two processes to communicate with each other without interfering with one another. They are used for synchronization and control of shared resources like file handles, memory addresses, and network connections. In a semaphore, either the sender or receiver can release it (i.e., acquire) if it is full before using it. This allows communication between processes that may have different access rights to the resource being shared. Semaph
