Random Response

Eu recunosc din prima ca nu ma pricep la hardware. Din toata partea de hardware eu am invatat cel mai bine sa curat coolere-ul , sa schimb siliconul de pe procesor si sa resetez bios-ul.

Asa ca recunosc ca m-am inselat cu privirea la virusii de ram, nu sunt asa cum am zis eu, de fapt functioneaza prin copierea codului malitios intr-un fisier de baza a sistemuli (ex: .COM .EXE ) si se incarca in memorie abea dupa executarea fisierului compromis (deci nu se stocheaza in ram).

Acum cat priveste capacitatea ramului de a stoca informatii dupa ce calculatorul a fost inchis… Ei bine, asta e discutabil mai acvv si fuzy , findca exista mai multe tipuri de ram.

Sunt uimit ca, in momentul in care v-ati documentat nu ati trecut pe la wikipedia sa cititi si articolul de acolo.

O sa aflati in randurile ce urmeaza ca exista 2 tipuri de ram : Volatile ( DDRAM, SDRAM, s.a.m.d ) si Ne-Volatile ( NVram ) . Cele Ne-Volatile stocheaza informatia chiar si dupa ce calculatorul a fost inchis pentru ca functioneaza pe alte sisteme ce nu deterioreaza informatiile stocate (ex: inductie magnetica ).

Non-volatile random access memory (NVRAM) is the general name used to describe any type of random access memory which does not lose its information when power is turned off. This is in contrast to the most common forms of random access memory today, DRAM and SRAM, which both require continual power in order to maintain their data. NVRAM is a subgroup of the more general class of non-volatile memory types, the difference being that NVRAM devices offer random access, like hard disks.

The best-known form of NVRAM memory today is flash memory. Some claim flash memory to be a truly “universal memory”, offering the performance of the best SRAM devices with the non-volatility of Flash. To date these alternatives have not yet become mainstream.

Acum sa privim mai indeaproape memoria flash:

Flash memory is non-volatile computer memory that can be electrically erased and reprogrammed. It is a technology that is primarily used in memory cards and USB flash drives for general storage and transfer of data between computers and other digital products. It is a specific type of EEPROM (Electrically Erasable Programmable Read-Only Memory) that is erased and programmed in large blocks.

Nu e vorba de memoria ROM prietene, ROM-ul reprezinta modul de citire a datelor si nu are nici o legatura cu capacitatea memoriei de a sta scrisa dupa ce a fost privata de curent fiind doar o proprietate a memorilor NV (ex: NVRAM devices offer random access) .

ROM is an acronym for Read Only Memory, a type of unchangeable memory residing in chips on your motherboard. ROM contains the bare minimum of instructions needed to start your computer…. Incidentally, the term “ROM” is also used, not entirely correctly, when referring to some kinds of storage media that can’t be modified, such as CD-ROMs.

Toate cele bune, prietene
