OS resource management techniques[edit]

Resource management is the dynamic allocation and de-allocation by an operating system of processor cores, memory pages, and various types of bandwidth to computations that compete for those resources. The objective is to allocate resources so as to optimize responsiveness subject to the finite resources available. [3]

Technique Description
scheduling Scheduling is the method by which work is assigned to resources that complete the work.[4]. There are many different scheduling strategies. The main purposes of scheduling algorithms are to minimize resource starvation and to ensure fairness amongst the parties utilizing the resources[5]
policies Given a particular task, policy refers to what needs to be done (i.e. activities to perform) and mechanism refers to how to do it (i.e. implementation to enforce policy).[6]
multitasking foo
virtual memory foo
paging foo
interrupt foo
polling foo
