Definition of Auxiliary Memory features
Among the various devices found in the hardware of the computer , find the group of memories , which in the first place we find the memories Elementary comprising the RAM and ROM who assist the functions of central processing unit providing an greater overall performance of the equipment, but also have the ability to Store Data
Definition of auxiliary memory
On the other hand, we have the group of Secondary Memories , which are also known as Auxiliary Memory , which, unlike RAM , for example, do not have a temporary storage of the processed Data , but allow them to be saved permanently, including when we disconnect the computer from its electrical power supply , so it can be affirmed then that it is a Permanent Storage of this information.
Secondary or auxiliary memory is a computer the set of devices that store complementary to those stored in main memory data.
In computer science and for a typical computer, there are two types of memory: primary and secondary. Main memory, which is usually an inherent part of the system consists of a hard drive or disk that is located within the CPU Unit or Central Processing Unit and may (or may not) be extended until the user is considered. These memories often have a capacity of over 100 GB and can store much of the data files a user normally uses.
What is the difference between secondary and auxiliary memory?
It is then made up of a great variety of Storage Media that allow the storage of a large amount of data, differentiable from other memories not only in regard to this quality, but also in its quality, since the storage capacity is vastly superior.
Its operation is not autonomous, since they precisely work in conjunction with the Primary Memory , so, for example, for the reading of a file in a Storage Medium , it is possible that the use of RAM Memory is required to speed up this reading and increase the performance of the processes.
The most used of the Secondary Memories without a doubt that is the case of the Hard Drive , the storage medium par excellence in a computer, having a large capacity but without as much speed as other types of memory, being economical, with a very high durability and offering support not only for all files present on the computer but also to
How do Auxiliary Memory work
Secondary memory, on the other hand, acts as an add-on device and is usually located outside the computer, such as one or more peripherals have additional space to store more data than going into the computer’s hard drive. Although it is often slower or smaller in capacity memories, they are a good choice to complement in expanding the availability of any computer space.
If you talk about auxiliary memory that can be referred to old floppy disks, disks or CD-ROMs, DVDs, pen drives, Zip disks and other alternatives. Each of them has different characteristics that fit one purpose or another. Also, in most cases they can be purchased in different sizes according to the user’s needs.
Uses of Auxiliary Memory
Regarding Optical Media, we find a large number of formats according to current technologies that are constantly evolving from the use of the classic CD-ROM and CD-R to the current HD- DVD and the most advanced of Blu- ray technology. Ray , which offer different storage capacities at a very high portability.
We also have the case of Flash Memories , which are a portable storage medium that allows us to use this memory in a large number of mobile devices, generally acting as a link between a laptop and a computer, or as a support for them to can store a larger number of files. For these cases, usually it has a slot reader card or an adapter that leverages the connectivity absolute El Puerto USB , easier to read and download files hosted there.
Auxiliary memory devices for the computer are connected via USB ports or in cases are directly related to main memory, forming a subsystem. In addition, many of them allow device mobility, taking information from one computer to another easily and quickly. Thus, the user experience on the network expands.
