There are several terms you might have heard or read in relation to a computer system
. Undoubtedly there are several you have no idea what they necessarily mean. This article is going to focus on the particular query 'what is cache memory?' You probably have heard this before in regards to your web browser any time somebody informs you to clear your cache.
The actual cache memory on a laptop or computer system is actually a little part of random access memory also referred to as RAM that has been allocated to keep operations that happen to be executed often. This helps to speed up these kinds of functions as it won't have to search through the personal computer, making these kinds of activities perform faster.
Naturally the more cache memory you have the quicker your platform will probably run. By having more of this memory you are able to store much more data. Lately the ordinary laptop or computer system comes with much more as compared to years ago.
Allow us to give more terminology and also information as we continue our article on cache memory explained. This particular memory is certainly known as SDRAM that represents high speed static memory. It really is much faster n comparison to the DRAM that is your system's primary memory.
Several cpus have something known as Level I (L1) ram built into them; they are usually from 8kb to 16kb and also used on Intel and Pentium processor chips. Current computers normally will not have L1 cache memory, but rather include 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 could include onto this that right now there is a Level 3 (L3) cache memory. This particular scenario is when your computer system has L1 and L2 built into the CPU processor and then comes with an external chip which makes it L3.
You will also note there is something named disk cache. This is the part of system RAM which is slower compared to the L1, L2 and L3. This can be used to read and write to the specific hard disk and is usually run by some kind of software.
Lastly there is something known as peripheral cache memory. This is generally for a cd-rom drive or maybe dvd-drive; it is much slower in contrast to L1, L2 and L3 and slower than that of the hard drive cache. With that being said, these will be cached to the hard disk.
