In this article, we'll talk about the structure of memory.
PAO's fleeting memory (took to drive) it is undoubtedly available for the processor, communication is done using store and load statements. - here I am referring to the architecture of computers, I will also mention,that the processor automatically takes an instruction to execute. - This is very important.
Now, I'd like you to really focus, the processor communicates with the operating memory using the so-called. memory rails. There may be a situation in which, unfortunately, there is not enough data to carry out an order. This is because of this, that access to PAO may take not one but several processor cycles.
What is the solution to the problem? Well, the CACHE cache, which you have certainly heard about more than once.
The cache is a small memory of small size, and is used to store the next order to be executed. the processor then checks its cache memory and does not have to wait a few cycles to get from PAO.
You are probably asking yourself about the relationship between working memory and disk.
The disk is the source of information that will be processed. Now a little bit about the PAO mapped file. Thanks to this technique, you can use the file in the same way as if it was all loaded into memory.
Finally, I will come back a bit to the disks. Two such factors determine disk speed: The first is the transfer rate, i.e. the rate of information transfer between the disk and the computer, and the second is the head position algorithm. Such a curiosity : the disk also has its "disk cache". But not to confuse you, I will not talk about it.
Remember when we talked about multiprocessor systems in the previous section? There, each processor has its own cache.
I invite you to read on.
