How a Computer Remembers A computer’s memory works in similar way. There are some pieces of information that need to be stored away. Others can be forgotten once the computer has worked on them. To separate the two types of information, a computer has two memories called ROM and RAM.

ROM stands for Read Only Memory. ROM carries the information the computer needs to carry out its task. This information is built into the computer and cannot be altered. It stays there even when the computer is switched off, just as your memory of how to get to the park stays with you until you need it again.

RAM stands for Random Access Memory, or read and write memory. This contains the information the computer needs to carry out the particular task you want it to do now. When you switch off the computer, RAM empties itself. You can save your work on CD-ROM. DVD ROM disks, floppy disks, flash drives, etc.

Storing Information ROM and RAM are both made up of memory cells, Each memory cell stores binary digits. A chip may be able to store millions of bits. It is easy to see that the size of the computer’s RAM is important because RAM has room for it. With some computers, it is possible to add extra memory chips to increase the RAM.
