don't know whether it is possible so generally to raise the question, but I was wondering if there's any file system in RAM? For example, take a regular bar DIMM DDR2 PC6400. Speaking of narrow-minded — it's how that information is stored. It means that the memory is/can be a file system.

RAM is a large matrix! :-)
No matter how you thought I was kidding, but it is. There are banks on the RAM (those are the black chips torcasio of the Board). Every Bank is located permanently writable matrix. Everything inside works locations. Reading of the RAM occurs by choice of row and sabsa, and then issued information. Everything works at a certain clock cycle.
If you need to store files in RAM at the OS level, use RAM disk.

Yes, in most distributions, /tmp is in RAM: none /tmp tmpfs defaults 0 0<br>
The size of the shared memory which will be created by FS, can be changed when mounting.

In Linux for this is tmpfs
Is created like this:
sudo mount-t tmpfs -o size=2G,nr_inodes=30k,mode=0777 tmpfs /mntpoint
I like using tmpfs in the script to place a large number of small temporary files, so firstly do not pull the disk, and secondly just to speed up the process.

For CPU your "Planck-memory", being stuck in the charge is seen simply as a set of cells with addresses from N to M (number of cells = number of bytes in the strap, 2 GB is slightly more than 2 billion), each of which can be put 1 byte of data. But you can the file system to create it, but on the OS level.

File system — an abstraction over the storage device. RAM is generally used without it, and the disks are normally used with her. But neither the first nor the second is not absolute. And there is such a thing as virtual memory, which transparently (to the application) displays the addresses of the memory sectors of the disk through the file system of the disk.

"In fact," you have said, in OZ the data is stored as a one-dimensional array. There are no FS, only "address" a memory number (a positive integer). Therefore, in 32-bit systems, the memory size is limited to 3 gigs — more numbers in there to create.

I ask again because I this leads to the next question — What's the difference between a hard drive and OZ? Of course, if only to consider the data storage and the file system. If the processor sees the file system on the hard disk, or it there too, only the set of cells with addresses? Or he is on a drive not looks, and the data from the hard drive first loaded into RAM?
