Here's hoping our handy Glossary can set you straight, like a bridge over troubled water.

Random Access Memory

Random Access Memory is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order (that is, at random). The word "RAM" is often associated with volatile types of memory (such as DDR2 memory chips), where the information is lost after the power is switched off.


• ADAM ships with 1GB of DDR2 RAM.

Read Only Memory




In modern PCs, "Read Only Memory" (or Flash) is used to store the basic bootstrapping firmware for the main processor, as well as the various firmware needed to internally control self contained devices such as graphic cards, hard disks, DVD drives, TFT screens, etc, in the system. Today, many of these "read-only" memories – especially the BIOS – are often replaced with Flash memory (see below), to permit in-place reprogramming should the need for a firmware upgrade arise. However, simple and mature sub-systems (such as the keyboard or some communication controllers in the ICs on the main board, for example) may employ mask ROM or OTP (one time programmable).  2c – Memory and Storage
