WebA write-through cache guarantees that data is always up-to-date in memory A store in a write-through cache can safely overwrite the old data, regardless of whether the store is a hit or a miss A store in a write-back cache needs first to know whether it is a hit or a miss and then proceed with writing the data (harder to implement, perhaps Webd) Spatial locality View Answer 9. What are the advantages of arrays? a) Objects of mixed data types can be stored b) Elements in an array cannot be sorted c) Index of first element of an array is 1 d) Easier to store elements of same data type View Answer 10.

WebIn computer science, locality of reference, also known as the principle of locality,[1] is the tendency of a processor to access the same set of memory locations repetitively over a short period of time.[2] There are two basic types of reference locality – temporal and spatial locality.

This usually stems from the fact that the most basic data structure building blocks are arrays and structs, both of which store multiple elements adjacently in memory. Web1.2.1 Temporal Locality. Temporal locality is the tendency of programs to use data items over and again during the course of their execution. This is the founding principle behind caches and gives a clear guide to an appropriate data-management heuristic.
