A semaphore is synchronization primitive in linux and other operating system and manage or control access to a common resource by multiple process in concurrent system like multitasking operating system.
Semaphore have two types
1. Binary semaphore
2. Counting Semaphore
Semaphore is used for managing access to finite number for resources. They provide a mechanism process to synchronize process and managing access to shared resources and helping prevent condition races and ensuring that the system operates smoothly in under heavy multitasking condition
A semaphore is a variable or abstract data type that is used to control access to a common resource by multiple processes in a concurrent system.
Semaphores are a fundamental tool in concurrent programming, especially in operating systems like Linux. They provide a mechanism to synchronize processes and manage access to shared resources, helping prevent race conditions and ensuring that the system operates smoothly even under heavy multitasking.
