Assembler - An assembler is a program that transforms source code written in Assembly Language to the machine language. All commands in Assembly Language will transform to machine language. OR Compiler - A compiler is a computer program that transforms source code written in a computer language (the source language) into machine language. A compiler will transform all the source code then will list the syntax error. The source code will executable if there are no error. There are object code file. OR Interpreter - An interpreter is a computer program that transforms source code to machine language. It will translate the source code row by row. Syntax error will appear when the source code has an error. It will wait until the error has been corrected. There are no object code file. - 2 marks 30. a.
