Introduction
Stores
Newton data is stored in stores. A store is a physical device that stores data and is similar to hard drives or volumes on desktop machines. Each Newton has an internal store. When you insert a ROM or RAM PC card, it has an external store as well. At the time this book was written, Newtons only had these two stores. There may well be more stores in the future, however, as it is easy to imagine a Newton with more than one PC card slot. You can also imagine databases on a host machine appearing as soups in a pseudo-store.
In your understanding of stores, there are three important points to remember:
- You may assume that the first store is the internal store, but nothing else. The second store may or may not be the external store, and the number of stores is unlimited.
- Stores may appear or disappear while an application is running-- the user can eject or insert a PC card at any time.
- Not all stores are writable--a store could be on a ROM card or a write-protected RAM card.
