RAM and shorten RAM, and this type of temporary memory used in computers, since the information you lose them as soon as the power interruption him, if, for example, re-run the computer lost information. This type of memories is important is the set of program performance, he appoints km from space programs can be exploited to run, so keen professionals (especially concentrated their work on the complicated software such as design using advanced programs such as Photoshop and the rich de Max and others. On providing the best kinds of them, and are keen also on the increase because they are responsible for the rapid implementation of the processes and treatment.
