Semaphore in operating system?
Semaphore data type used to maneuver access to multiple sources. The sources usually pertain to parallel programming, or multi user networks.
How many semaphore flag methods are there?

Semaphore was invented in 1648 by Robert Hooke. The first use was by Claude Chappe in 1792 in France. The system conveyed messages from city to city by relay stations or towers.

Explain binary semaphore and its uses?
A binary semaphore is a semaphore with an integer value that can range only between 0 and 1. A binary semaphore can be simpler to implement than a counting semaphore, depending on the underlying hardware architecture.To implement it in terms of binary semaphores we need the following data structures: binary-semaphore S1, S2; i n t C; Initially S1 = 1, S2 = 0, and the value of integer C is set to the initial value of the counting semaphore S.The wait operation on the counting semaphore S can be implemented as follows: wait (S1) ; c--; i f (C < 0) { signal(S1) ; wait (S2) ; } signal(S1) The signal operation on the counting semaphore S can be implemented as follows: w a i t (S1) ; C++ ; i f (C <= 0) signal (S2) ; e l s e signal (S1) ;
