4.

Principle of Locality: Programs access only a small portion of the full address space at any instant of time

There are two kinds of localities

Temporal Locality (locality in time)

If a memory location is referenced then it will tend to be referenced again soon.

Spatial Locality (locality in space)

If a memory location is referenced, the locations with nearby addresses will tend to be referenced soon.

Choose the type of locality for the following types of data. Note that codes are stored in memory liked data.
