# What is Concurrency?

Concurrency:

when so many several instruction sequences executed at same time its called concurrency. In operating system having several process threads running in parallel at time of concurrency. These threads may communicate with each other through either shared memory or message passing.

Concurrency results in sharing of resources result in problems like:- deadlocks and resources starvation. It helps in techniques like coordinating execution of processes,memory allocation and execution scheduling for maximizing throughput.

Problems in Concurrency:-

- sharing global resources safely is difficult

- optimal allocation of resources is difficult

- locating programming errors can be difficult,because the contexts in which errors occur cannot always be reproduced easily.
