COW at times submitted to as implicit distribution or shadowing, is a resource management method utilized in computer programming to capably employ a duplicate or copy process on adjustable resources. If a resource is copied but not altered, it is not essential to make a new resource the resource can be shared among the copy and the original. changes must still make a copy, hence the method: the copy operation is deferred to the primary write. through sharing resources in this method, it is probable to considerably decrease the resource consumption of unchanged copies, while adding a small overhead to resource altering processes.
