AVR-Chat

You are asking the most basic questions that can be asked.  I do suggest 
that you need to do some homework.  Read the data sheets, there is a lot 
of information there.  Put what you read into context.  Go to Wikipedia 
and look these things up.  Use Google or hit the library for books on 
embedded processors.  We could spend weeks playing "20 questions" on 
these topics and you'd only half get what you need.  Study up on the 
topics that you don't understand and ask us specific questions to 
clarify key points where you don't fully understand it.

Key items for you to study:
FLASH non-volatile memory
SRAM (Static RAM)
Harvard vs. Von Neuman memory structures
Data vs. Instruction memory
Input/Output lines
Data direction register
TTL and CMOS, Schmidt trigger

have fun!
