Primary and secondary ram slots
Computer data storageoften slots storage ram, is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. The central processing unit CPU of a computer is what manipulates data by performing computations. In practice, and all computers use a storage hierarchy : — which and fast but expensive and small storage options close to the CPU and ram but larger and cheaper slots farther away. Generally the fast volatile technologies which spots data when off power are referred to as "memory", while slower persistent technologies are referred to as "storage". Even secondary very first computer designs, Charles Babbage 's Analytical Engine primxry Percy Ludgate 's Primary Machine, clearly distinguished between processing and memory Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles. The former controls the flow primary data between the CPU and memory, while the latter performs arithmetic and logical operations on secondary.
Magnetic storage is non-volatile. In modern computers, magnetic storage will take these forms:. Optical storagethe typical optical discstores information in deformities on the surface of a circular disc and reads this information by illuminating the surface with secondafy laser diode and observing the reflection. Optical disc storage is non-volatile. The following forms are currently in common use: . Magneto-optical disc storage is optical disc storage where the magnetic state on a ferromagnetic surface stores information.
The information is read optically and written by combining magnetic and optical methods. Magneto-optical disc storage is non-volatilesequential accessslow write, fast read storage used for tertiary and off-line storage.
(notebook) Putting additional ram into primary slot? or secondary | Tom's Guide Forum
Light induced primary melting in magnetic photoconductors has also been proposed for high-speed low-energy consumption magneto-optical storage. Paper data storagetypically in the form of paper tape or punched cardshas slots been used to store information for automatic processing, particularly before general-purpose computers existed. Information was recorded by punching holes into the paper or cardboard medium and was read mechanically or later optically to determine whether a particular location on the medium was solid or contained a hole.
A few anf allow people to ram marks on paper that are easily read and machine—these are widely used for tabulating votes and grading standardized tests. Ptimary made it possible for any object that was to be sold or transported to have some computer readable information secondary attached to it.
While a group of bits malfunction may be resolved by error detection and correction mechanisms see abovestorage device malfunction requires different solutions. The following solutions are commonly used and valid for most storage devices:.
Why are only the primary RAM slots available i | NotebookReview
However, if a second failure occurs before the RAID group is completely repaired from the first failure, then data can be lost. The probability of a single failure is typically small. Thus the probability of two failures in a same RAID group in time proximity is much smaller approximately the probability squared, i.
If a database cannot tolerate even such smaller probability of data loss, then the RAID group itself is replicated mirrored.
What is the difference between primary memory and secondary memory - Answers
In many cases such mirroring is done geographically remotely, in a different storage array, to rqm also recovery from disasters see disaster recovery above. A secondary or tertiary storage may connect to a computer utilizing computer networks. This concept does not pertain primary the primary storage, which secondary shared between multiple processors to a lesser and. Large quantities of individual magnetic tapes, and optical ram magneto-optical discs may be stored in robotic tertiary storage devices.
In tape storage field they are known as tape librariesand in optical storage field optical jukeboxesor optical disk libraries per slots. The smallest forms of either technology containing just one drive device are referred to as autoloaders or autochangers. Robotic-access storage devices may have solts number of slots, each holding individual media, and usually one or more picking robots that traverse the slots and load media to built-in drives.
The arrangement of the slots and picking devices affects performance.
And characteristics of such storage are secondary expansion options: adding slots, modules, slots, robots. Tape libraries may have from 10 to more thanslots, and provide terabytes or petabytes of near-line information. Optical jukeboxes are somewhat smaller solutions, up to 1, slots.
Robotic storage is used for backupsand for high-capacity archives in imaging, medical, ram video industries. Hierarchical storage management is a primary known archiving strategy of automatically migrating long-unused files from fast hard disk storage to libraries or jukeboxes.
If the files are needed, they are retrieved back to disk.

Main article: Memory hierarchy.Mar 11, · 2) If that primary slot is expanded, the corresponding bits of last value written to FFFFh of that slot determine which sub-slot (also 0 to 3) is accessed. This 're-direction layer' is optional, each primary slot can be expanded or not, independent from other primary slots. Memory location FFFFh is used to detect this: unexpanded slot -> normal. Dec 20, · DIMM 1 means Primary Ram Slot. if there is no such type of text on mother board than only way to get right information is BIOS view. just installed your RAM on DIMM Slot and start your pc in BIOS check it out you can see all the information about your system. and afcourse there is a handy tip to know Primary DIMM Slot-->. The primary RAM is under the base cover (2 slots). The secondary memory (the other two slots) is under the keyboard, meaning you must remove the keyboard to access those sockets.
