A program is a set of instructions that a computer follows in order to perform a particular task. Computing the chances of an error occurring in a computer program increase with the size of the program.
The Banker algorithm, sometimes referred to as the detection algorithm, is a resource allocation and deadlock avoidance algorithm developed by Edsger Dijkstra that tests for safety by simulating the allocation of predetermined maximum possible amounts of all resources, and then makes an "s-state" check to test for possible deadlock conditions for all other pending activities, before deciding whether allocation should be allowed to continue.
A sequence of instructions, in a computer language, to get the desired result, is known as
