RAM, or Random Access Memory, is “volatile.” This means that it only holds data while power is present. RAM changes constantly as the system operates, providing the storage for all data required by the operating system and software. Because of the demands made by increasingly powerful operating systems and software, system RAM requirements have accelerated dramatically over time. For instance, at the turn of the millennium a typical computer may have only 128MB of RAM in total, but in 2007 computers commonly shipped with 2GB of RAM installed. Nowadays it’s common to find computers with 8 – 32GB of RAM.
