Race Condition is Several processes access and manipulate the same data concurrently may lead to incorrect shared data.

The Producer-Consumer problem is a classic multi-process synchronization problem.

The job of the consumer is to generate the data, put it into the buffer, and again start generating
data

The producers and consumers share different memory buffers that is of fixed-size (bounded buffer)

in producer consumer problem We can do so by having an integer counter that keeps track of the
number of full buffers. Initially, counter is set....

counter is decremented by the producer after it produces a new buffer

in producer consumer problem, we use counter-- in … stage

in producer consumer problem, we use while(counter == BUFFER_SIZE); in … stage

in producer consumer problem, we use while(counter == 0); in … stage

in producer consumer problem, we use buffer[in] = next_consumed

in producer consumer problem
in =.........

in producer consumer problem
out =........

in producer consumer problem next_consumed =
buffer[in]

share common variables, updating table, writing file, etc..

When one process in critical section, other may be in its critical section

Each process must ask permission to enter critical section in …..

If process Pi is executing in its critical section, then no other processes can be
executing in their critical sections

Peterson’s Solution is a hardware-based solution to the critical-sectio

Peterson’s Solution is … to be synchronized
