Does the SSD and HD appear as one?

[Nishi100]

I'm going to be buying this iMac, with a HD and SSD together. However, am a bit confused on how the HD and SSD works together:

1) Do they appear as one drive in the finder?
2) If you download an app, then install it; will the downloaded *zip* (saved in "Downloads") be stored in the HD, and the app installed on the SSD (obviously saved in "Applications"), automatically?

1) They are 2 distinct drives in the Finder.
2) Wherever you designate your download folder, that is where you will download items. Manypeople use the SSD as the boot drive for the OS and applications, storing Home folder data/files on the HD.
