A

Produces a program in a different language

19
Q

Define Semantic analyzer

A

Checks for errors not detected

20
Q

Define Optimization

A

Improves program by making it smaller or faster

21
Q

Define Code Generator

A

translates code to machine language

22
Q

Define Symbol Table

A

contains type and attribute information of user defined names

23
Q

Define Pure Interpretation systems

A
  • programs are interpreted with no translation
  • easy to debug but execution is slower and requires more space
24
Q

Define Hybrid Interpretation System

A

translates high level language to an intermediate language designed for easy implementation

25
Q

This hardware specifies that the code from another file is to be included and processes a program before the program is compiled

A

Preprocessors
