Answer 8

Interpretation

Question 9

Answer 11

Speed

Question 12

What implementation takes a high-level language program and translates it to an easy-to-read interpretation.

Answer 12

Hybrid Implementation Systems

Question 13

How would you translate a java code

Answer 13

You define virtual language, write compiler to write to their language, then write to interpreter that understands it.
