Virtual memory is defined as an abstraction of the main memory that extends the available computer memory by storing parts of content RAM that are not active. Cache memory is where data that is accessed often is stored so you are able to have quick access to it.

Virtual (or logical) memory is a concept that, when implemented by a computer and its operating system, allows programmers to use a very large range of memory or storage addresses for stored data. The computing system maps the programmer's virtual addresses to real hardware storage addresses. Usually, the programmer is freed from having to be concerned about the availability of data storage.

In addition to managing the mapping of virtual storage addresses to real storage addresses, a computer implementing virtual memory or storage also manages storage swapping between active storage (RAM) and hard disk or other high volume storage devices. Data is read in units called "pages" of sizes ranging from a thousand bytes (actually 1,024 decimal bytes) up to several megabyes in size. This reduces the amount of physical storage access that is required and speeds up overall system performance. Cache ram is very high-speed RAM chips which sit between the CPU and main memory. It stores (i.e., caches) memory accesses by the CPU. Cache ram helps to alleviate the gap between the speed of a CPU's megahertz rating and the ability of RAM to respond and deliver data. It reduces the frequency that the CPU must wait for data from the main memory.

Is cache memory equal to virtual memory?

No! ; Cache memory is integrated in the CPU. Virtual memory is a part of the hard drive that the OS use as ram memory, when running out of real ram memory.


Differentiate between the physical virtual and cache memory Explain briefly?

Virtual memory is a type of memory that is allocated by the operating system and is used to speed up operations. Cache memory is RAM that the CPU can access faster than regular ram which is considered physical memory. When the CPU is looking for data, it checks the cache memory first, recently used data will still be in the cache. If it does not find it there, it moves on to use the physical memory. Anytime a program or file is opened, it is first loaded into RAM (physical memory).


What is the difference between ram ROM cmos cache and virtual memory?

Short answer is difficult, but we need one. Your computer contains all kinds of virtual memory.. on the RAM chips primarily. Maxed-out older computers resort to using space on the disk drive, which is relatively slow. A cache is a saved memory of what you have recently been doing, and is used since it is very fast. It duplicates a finite amount of what is in virtual memory.


What is the difference between cache-memory and primary-memory?

Cache memory is smaller and quicker, primary memory larger and slower.


What are the type of cache memory?

There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.


What is the difference between cache memory disk cache?

memory cache is on memory RAM, disk Cache is on the hard drive. They make things to get faster. For instance Google Earth use this disk cache to show you offline images.


What are the two types of cache memory?

There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.


What is the name of the memory that sits between the processor and the primary memory?
