Students should have at least basic knowledge about different concepts of computers. Having information about language processor is also important. Technology is very improving for all the students so they should know how it works and what are its parts. The topic of language processor can come in the exam so students should study it properly. Assembly language is machine-dependent, but the mnemonics used to represent the instructions within it are not directly understood by the machine, and high-level languages are machine-independent. Computers understand machine language, that is, instructions in the form of 0’s and 1’s. Writing computer programs directly in machine language is a tedious task. Programs are mainly written in high-level languages such as Java, C++, Python, etc., and are called source code. This source code cannot be run directly on a computer and must be translated into machine language for execution. A language processor that reads a complete source program written in a high-level language at once and translates it into a machine language equivalent is called a compiler. If there are errors in the source code, the compiler marks them as line numbers at the end of the compilation. A source program in assembly language input that contains assembly language instructions. The output produced by the assembler is object code or machine code that the computer can understand. Hope all the students have understood the language processor.
