Working set
Working set is a concept in computer science which defines the amount of memory that a process requires in a given time interval. == Definition == Peter Denning (1968) defines "the working set of information W ( t , τ ) {\displaystyle W(t,\tau )} of a process at time t {\displaystyle t} to be the collection of information referenced by the process during the process time interval ( t − τ , t ) {\displaystyle (t-\tau ,t)} ".
