A processor tends to spend the vast majority of the time working in tight loops that reference small amounts of information. Because, compared to the CPU, system memory is rather slow (modern PC processors can have a speed difference of nearly 30:1) cache allows the CPU to keep this a of memory handy that the CPU uses. Most line caches use a first-in, first-out approach, but more and more complicated algorithms are becoming common.

What is data memory?
cache memory refreshes instantly so access time is faster
How does memory cache speed up computer processing A Cahce memory doesn't need to be refreshed so access time is faster B Cache memory refreshes instantly so acess time is faster. C Cache memory uses?
A
Is Cache memory generally slower than RAM?
Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory. Cache Memory generally comes in smaller size (3MB, 6MB etc) than the RAM (512 MB, 1GB,2GB.....)
What is called A reserved area of the immediate access memory used to increase the running speed of the computer program?
cache 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).
Cache memory and register memory?
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
How does a two-way set-associative cache improve memory access efficiency compared to other cache configurations?
A two-way set-associative cache improves memory access efficiency by allowing each cache set to store data from two different memory locations. This reduces the likelihood of cache conflicts and increases the chances of finding the requested data in the cache, leading to faster access times compared to caches with fewer associativity levels.
What is the function of CPU cache?
Many CPUs have what is known as a CPU cache. The function of this CPU cache is to speed up access to data.
Cache memory enhances?
memory access time.
Which memory has the shortest access time?
cache memory
Is cache memory a removable memory?
No, a cache memory is often used to store data that has been needed recently on grounds that it will be faster to access when/if it is needed again. When data that is requested is contained in the cache you have a cache hit, and when you have to retrieve it from the hard drive (or where ever its original storage was) again it is called a cache miss. Retrieving data from the hard drive is slower than retrieving it from the cache.
Where is cache memory located?
Cache memory is built into the central processing unit, commonly known in short as the CPU, or it can be located on a separate chip next to the CPU. In other sense, cache is located between CPU and Main Memory in the memory hierarchy of a computer system. just type allinurl:cache memory, in google search and you will find your answer with more pictures and a lot more about cache memory.
