Scientists have revised their model of memory, to replace short-term memory with working memory. What is the difference between short-term memory and working memory?

Short-term (sensory) memory has been defined as a temporary storage unit for verbal information. Sensory memory consists of sensory information retained in an unprocessed form in the sensory system through which it entered. This form of memory is short lived (0.5-3 seconds) - thus called short-term, but has a large capacity.

Working memory is defined as including active information processing for all kinds of information.
