2. Digital Media
The digital world is a description of an analog world that is analogous in some way to the physical world.
Digital images represent light intensity and frequency (color) using binary numbers.
Digital audio represents sound intensity and frequency (pitch) using binary numbers.
Digital video combines images and audio across time.
We are exploring the boundary of sensory space and cyberspace.

7. Network Drives and Turning in Assignments
There are Faculty-Folders and Student-Project links on most of the lab iMacs.
Or use Finder -> Go -> Connect to Server, enter
afp://instructionaltech.kutztown.edu
Faculty-Folders -> Parsons -> Outbox has handouts.
You must turn in assignments under my course Inbox.
You must create a Folder FirstLast (using your name) under Student-Projects today.
Always save a copy of your current assignment folder under your named directory here.

8. Some Quick File Manipulation
Finders -> Applications -> TextEdit
My name is First Last and this is my TextEdit file of September 2011.
TextEdit Save As FirstLastEdit.rtf on the Desktop. Close file – TextEdit persists. Quit TextEdit.

9. Making and Zipping a Folder and Testing Networked Storage
Make a Folder on Desktop called F.
Use Return to rename it to FirstLastDay1.
Move FirstLastEdit.txt into it.
Go inside via Finder, Open & Close the file.
Right-click -> Compress FirstLastDay1
Drag FirstLastDay1.zip to Student storage.
Drag FirstLastDay1.zip to Parsons Inbox.
Once these are verified, drag Desktop copies to the Trash can.

Rename this to something intelligible.
The folder where you store these files is always FirstLastProject, where “Project” is a project name.
