Task 3: Introducing Secondary Memory

Summary:

Introduce the concept of secondary memory.

Detailed Explanation:

•  Tell class that secondary memory is something humans use so that they don't have to keep all the information they need in permanent memory (their brain). Humans use secondary memory to store information, so we can retrieve it at some later date.

•  everyday [Ans: books, the notes we write.] •  occasionally [Ans: tape recorders, videos ]

•  Tell class that computers also have secondary memory
