Basically a compiler is a program whose purpose is to translate high level languages like C, C++, FORTRAN etc into the machine code which is the binary code which is understandable by the computer. After being converted into machine code, the program can be run on the computer.
Besides having the benefit of fast execution among others, there are some disadvantages related to a compiler.
The compiler is not very good at finding errors in a program which makes the removal of errors (Debugging) a little difficult. Another disadvantage of compiler is that even when an error has been removed for the program, the whole program would start compiling from the beginning, so the time consumed in executing a program may take longer.
