Interpreter

Instructions of a high-level language are coded in many statements. At the time of their
execution, they are converted statement by statement into machine code by using a system
software called interpreter. There are certain disadvantages of interpreters. As instructions are
translated and executed simultaneously using interpreters, they are very slow for executing
large programs. Hence, interpreters are not suitable for most application developments.

Compiler

In contrast to interpreter, compiler provides faster execution speed. Compilers do not translate
and execute the instructions at the same time. They translate the entire program (source code)
into machine code (object code) at one time. Using linker, the object code is converted into
executable code. As compared to interpreters or assemblers, compilers are preferred in the
development of application software.
