19. Computer Language
Language
Low level
Language
1. Machine language
2. Assemble language
High level
language

20. Low Level Language
Easily Understandable for Computer
Execute Fast
Machine Dependent
Inefficient in error finding
Hard for logic development
Machine language: Directly executed without any translation.
Instruction written in what can understand by processor.
Assemble language: Instructions are written in codes and
symbolic address.

21. High Level Language
Human understand easily
Slow in execution
Slow in execution
Easy in error finding
Easy in developing logic
