Working memory replaces our concept of short term memory. It is best to abolish short term memory from our memory. U working memory: the memory system responsible for the short term mental storage and manipulation of information. U analogy: in a computer, there are two means by which information is stored: V working memory is most like ram, while ltm is most like hard drives. V in ram, information can be brought into a work space temporarily but quickly, to manipulate and compute, and then when you are finished, you can wipe ram clear and put new information in. V a hard drive is slower to access and the representations put there are intended to stay there, and not be wiped out. V the central executive controls what happens in the different storing systems. Ram does not have something like the central executive.
