8. What is computer language

• Actually it is a bundle of different instructions.
Those instructions are placed in such a
manner by which the computer can produce
the desire result against a specific type of

computer programming. Computer program
take input from users and produce the result
after manipulating those inputs with the help
of some mathematical calculation.

13. What are compiler and interpreter
• Compiler and Interpreter both are the set of
programmes. They convert Human
understandable programming language to
machine level language.
• The basic difference between them is that
compiler at first reads the whole programme and
then convert it to the machine level language
where as interpreter do the same job line by line.
• Ex: compiler: C, C++, etc.
• Ex: interpreter: BASIC, MATLAB, etc.
