Other system programs include language translators i. Programs written in a high level language are either directly executed by some kind of interpreter or converted into machine code by a compiler and assembler and linker for the cpu to execute while compilers and assemblers generally produce machine code directly executable by computer hardware, they can often optionally produce an intermediate form called object code. Language translators compiler interpreter assembler. Early versions of lisp programming language and dartmouth basic would be examples of the first type. A compiler converts highlevel language program code into machine language and then execute it.
Language processors are language translation software like assembler, interpreter and compiler. A compiler is primarily used for programs that translate source code from a highlevel programming language to a machine level language to create an executable program.
