RAM stands for Random Access Memory. Think of it as a container where the things you`re doing on your Chromebook — both what you can see and what`s happening behind the scenes — can store and retrieve data randomly. That means it can access any byte of that data without affecting the preceding or trailing bytes. That makes it fast because the location of the data you need has no effect on the time it takes to read, write, or overwrite it. With no moving parts, there are no mechanical limitations on access times. RAM is also volatile — once the integrated circuits lose their power, the data disappears.
