This glossary is far from complete. We are constantly adding computing terms.


RAM
Random Access Memory. An area of memory that can be accessed very quickly, acting as a temporary storage area for program applications and data. This type of memory is usually "volatile", that is, the contents are lost when the computer is switched off.

record
A set of related data items about a person or object, e.g. the personal record of a student in school.

ROM
Read Only Memory. An area of memory which can store software programs and data, but cannot be changed by a program. Not volatile, that is, contents are not lost when the computer is switched off, so it is often used for storing programs needed when the computer "boots up".

router
A hardware device which allows one network to connect to another.
