RAM full form: Random Access Memory

How to say it: as a word, not letter by letter.

RAM stands for Random Access Memory. It is the working memory of a computer or phone: the place where the programs you are using right now, and the data they are working on, are kept so that the processor can reach them quickly.

Why "random access"

The name means that any part of the memory can be reached directly and equally fast, in any order. Older kinds of storage, such as tape, had to be read from the start to reach a particular place.

RAM forgets

RAM is volatile: it holds its contents only while the power is on. When you switch off, everything in RAM is lost. That is why unsaved work disappears in a power cut, and why you must save a file to the storage drive to keep it.

RAM and storage are different

This is the most common confusion. RAM is like the top of your desk: what you are working on at the moment. Storage, the hard disk, SSD or a phone's "128 GB", is like the cupboard where things are kept for later. A phone advertised as "8 GB + 128 GB" has 8 GB of RAM and 128 GB of storage.

What more RAM gives you

With more RAM a device can keep more apps and browser tabs open at once without slowing down. When RAM runs short, the system has to keep moving things out to the much slower storage, and everything drags.

RAM and ROM

ROM, Read Only Memory, keeps its contents without power and holds the small program that starts the device. On phone specification sheets "ROM" is used loosely to mean storage, which is not the strict meaning.
