In order to reduce the complexity of designing and building computers, nearly all of these are made to execute relatively simple commands (but do so very quickly). A program for a computer must be built by combining these very simple commands into a program in what is called machine language. Since this is a tedious

introduction to compiler-writing and a do-it-yourself kit for the compiler-writer, giving enough detail for you to understand the principles of the subject, than as a survey of past history or present horizons. The principles of interpretation are close enough to those of compilation for chapter 19 to give a simple introduction.
1.2 Compilers. A compiler is a translator from a high level language to the assembly code of a particular. CPU. A compiled program works on. • the particular CPU and One way to understand how an interpreter works is to write one for the LMC. Many systems combine aspects of both compilers and interpreters.
LECTURE 2 Compilers and Interpreters. Page 2. COMPILATION AND INTERPRETATION. Programs written in high-level languages can be run in two ways. • Compiled into an executable program written in machine language for the target machine. • Directly interpreted and the execution is simulated by the interpreter.
Abstract— This paper essays the basic understanding of compiler and interpreter and identifies the need of compiler for interpreted languages. It also examines some of the recent developments in the proposed research. Almost all practical programs today are written in higher-level languages or assembly language, and
