Random Access Memory
Executing programs use RAM to store data. Data stored in RAM is lost upon a reset. The operating system
manages how applications use RAM. It only allows applications and component processes and services to
use RAM when required. It may cache recently used processes in RAM, so they restart more quickly when
opened again, but it will erase the cache if it needs the RAM for new activities.
