2. Random-access memory - Wikipedia

   en.wikipedia.org/wiki/Random-access_memory

   A portion of the computer's hard drive is set aside for a paging file or a scratch partition, and the combination of physical RAM and the paging file form the system's total memory. (For example, if a computer has 2 GB (1024 3 B) of RAM and a 1 GB page file, the operating system has 3 GB total memory available to it.)

3. Reliability, availability and serviceability - Wikipedia

   en.wikipedia.org/wiki/Reliability,_availability...

   Availability is typically given as a percentage of the time a system is expected to be available, e.g., 99.999 percent ("five nines"). Serviceability or maintainability is the simplicity and speed with which a system can be repaired or maintained; if the time to repair a failed system increases, then availability will decrease. Serviceability ...

4. Dynamic random-access memory - Wikipedia

   en.wikipedia.org/wiki/Dynamic_random-access_memory

   This property can be used to circumvent security and recover data stored in the main memory that is assumed to be destroyed at power-down. The computer could be quickly rebooted, and the contents of the main memory read out; or by removing a computer's memory modules, cooling them to prolong data remanence, then transferring them to a different ...

5. Non-volatile random-access memory - Wikipedia

   en.wikipedia.org/wiki/Non-volatile_random-access...

   Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data ...

6. Ferroelectric RAM - Wikipedia

   en.wikipedia.org/wiki/Ferroelectric_RAM

   Ferroelectric RAM (FeRAM, F-RAM or FRAM) is a random-access memory similar in construction to DRAM but using a ferroelectric layer instead of a dielectric layer to achieve non-volatility. FeRAM is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory .
