Because of two things:
ü Program and data references within a process tend to cluster à only a few pieces of a process will be needed over a short period of time.
ü It is possible to make intelligent guesses about which pieces will be needed in the future, which avoids thrashing.

What is Principle of locality?
The principle of locality states that programs tend to access data and instructions that are near each other in memory. This principle is the basis for memory caching strategies to improve performance by storing frequently accessed data closer to the processor. By exploiting spatial and temporal locality, memory access patterns can be optimized for faster processing.
What are the three forms of locality?
Temporal locality: Refers to the idea that if a memory location is accessed, it is likely to be accessed again in the near future. Spatial locality: Indicates that if a memory location is accessed, nearby memory locations are also likely to be accessed in the near future. Data locality: Refers to the principle of keeping frequently accessed data in close physical proximity to reduce latency and improve performance.
How do you read virtual memory?
Find a virtual psychic to read your virtual memory.
How does virtual memory work?
virtual memory works just like as temporary memory does
What is deffernce between virtual and physical memory?
The difference between virtual and physical memory is that virtual memory refers to memory space while physical memory are chips like RAM. The memory space for virtual memory is made by operating system when there is insufficient physical memory.
What does the computer use when RAM is full?
Virtual memory, the answer is virtual memory.
When virtual memory is invented?
Virtual memory was invented in the early 1960s
Under Windows 2000XP physical memory and virtual memory are both managed by what?
Virtual Memory Manager
What is the difference between bitween pagefile and virtual memory?
pagefile is the virtual memory
What is another name for virtual memory?
Virtual Memory-: Virtual Mem is also known as Swap memory. Swap memory:- Swap mem is the type of memory which allocates by the harddisk in the form of extra RAM for better functioning of the application in the case if you are facing a lack of RAM in order to run that software
What type of memory stores data in a swap file on a hard drive high memory virtual memory extended memory random access memory?
virtual memory
Principle of locality relate to the use of multiple memory levels?
Temporal Locality: Concept that a resource will be referenced at one point in time will be referenced again. Cache miss traffic decreases fast when cache size increases and temporal locality determines sensitivity to cache size.Spatial Locality: Concept that likelihood of referencing a resource is higher if a resource near it was referenced. Cache miss traffic does not increase much when line size increases. Spatial locality determines sensivity to line size.
