subject: Cache Memory Explained Quickly [print this page] There are various terms you might have heard as well as read with regards to some type of computer device. Certainly there are several you have no idea what they mean. This article is planning to talk about the query 'what is cache memory?' You probably have often heard this before in relation to your internet browser when someone informs you to clear your cache.
The cache memory on a computer system system is usually a tiny part of random access memory also called RAM that has been allocated to keep operations that happen to be carried out often. This element helps to speed up these types of processes as it does not have to search through the personal computer, making these kinds of actions operate faster.
Of course the more cache memory you have the faster your platform is going to run. By using much more of this memory you are able to store additional information. Nowadays the standard personal computer system comes with far more as compared to in years past.
Allow us to present additional technical terms and information as we continue the article on cache memory explained. This kind of memory is certainly termed SDRAM that is known as high speed static memory. It is much quicker than the DRAM that is the system's principal memory.
A lot of cpus actually have something termed Level I (L1) ram memory built in them; they are usually from 8kb to 16kb and also used on Intel and Pentium processor chips. Newer computers normally will not have L1 cache memory, but rather have Level 2 (L2). L2 is in fact cache memory stored externally between processor chip and the specific DRAM.
Now in making points a little bit more complicated we can include on top of this that there is also a Level 3 (L3) cache memory. This circumstance is when the computer system has L1 and L2 constructed into the CPU processor and has an external chip that makes it L3.
You will also take note there is something termed disk cache. This is the portion of system RAM and is slower compared to the L1, L2 and L3. This can be used to read and write to the specific hard disk and is typically run by means of some type of software.
Finally there is something named peripheral cache memory. That is normally for a cd-rom drive as well as dvd-drive; it truly is much slower in contrast to L1, L2 and L3 and slower compared to the hard drive cache. That being said, these will be cached to the hard disk.
