What are the differences between these three words Error,
Defect and Bug.

Answer Posted / vijayalakshmi

Error: The deviation from the required logic, syntax or
standards/ethics is called as error.

There are three types of error. They are:



Syntax error (This is due to deviation from the syntax of
the language what supposed to follow).
Logical error(This is due to deviation from the logic of
the program what supposed to follow)
Execution error (This is generally happens when you are
executing the same program, that time you get it.)


Defect/Bugs: Thou these two words are used extensively in
the industry, but they carries the same meaning. Just the
one is the synonym of the other.



It can be defined as the effect because of the error which
lies in the program.
