All About Cache Memory-2016

I know its have been days since I posted any article.Sorry for this guys. But today we will learn something about CACHE MEMORY.

Some of you have heard about this term and some of you may not heard about this.First lets talk about how does it pronounce. Its pronounced as"cash memory".

So what is cache memory?

As its sound,its an other form of memory basically it is a temporay memory which stored data on a device no matter device is PC or android. Cache memory is a type of memory used to hold frequently used data. Cache memory is relatively small, but very fast.

The very effective way to increase the speed of the computer or any device is to use cache memory.
But don't get confused and even don't think that  this will make your Android faster than ever.
On android this is used for web page loading.Yes this memory is used to load web pages fast. Web browsers typically use a cache to make webpages load faster by storing a copy of the webpage files locally, such as on your local computer/android. This is referred to as a
Web cache.

The basic purpose of cache memory is to store program instructions that are frequently re-referenced by software during operation. Fast access to these instructions increases the overall speed of
the software program.

In computer-
A Cache is a small and very fast temporary storage memory. It is designed to speed up the transfer of data and instructions. It is located inside or close to the CPU chip. It is faster than RAM and the data/
instructions that are most recently or most frequently used by CPU are stored in cache.

The following are the deferent levels of cache Memory(depending upon the size of cache memory):-

Level 1 (L1) Cache
It is also called primary or internal cache. It is built directly into the processor chip. It has small capacity from 8kb to 128kb.

Level 2 (L2) Cache
It is slower than L1 cache. Its storage capacity is more, i-e. From 64 Kb to 16 MB. The current processors contain advanced transfer cache on processor chip that is a type of L2 cache. The common size of this cache is from
512 kb to 8 Mb.

Level 3 (L3) Cache
This cache is separate from processor chip on the motherboard. It exists on the computer
that uses L2 advanced transfer cache. It is slower than L1 and L2 cache. The personal computer often has up to 8 MB of L3 cache.

That's all about for today guys.If you liked this article don't forget to share this.
