Difference between Terminal and Non-Terminal Symbols (Compiler Design)

Terminal Symbol

A terminal is a symbol which does not appear on the left-hand side of any production.
Terminal symbols cannot be changed using the rules of the grammar.
terminal symbols, which are the characters of the alphabet that appear in the strings generated by the grammar.
a terminal symbol is one that cannot be broken down further, e.g. a literal character or digit (but not necessarily as it depends on the grammar).

example : Contant etc

Context Free Grammar

The analysis phase of a compiler breaks up a source program into constituent pieces and produces an internal representation for it, called intermediate code. The synthesis phase translates the intermediate code into the target program.

Analysis is organized around the "syntax" of the language to be compiled. The syntax of a programming language describes the proper form of its programs, while the semantics of the language defines what its programs mean; that is, what each program does when it executes. For specifying syntax, we present a widely used notation, called context-free grammars or BNF (for Backus-Naur Form)

Language Processor

Basically Translater i.e. Compiler and Interpreter

If a language processor is a translator that produces machine or assembly code as output (in object code or executable code) then it is called a compiler. If the language processor executes the translated program (output from the translator) then it is called an interpreter.

Relocatable VS Non- Relocatable Programming

A relocatable program may use many part of memory address in run time of a program. This type of program uses relative addressing and its address space can be change at run as requirement.

A Non-Relocatable program runs in fix address space. Location of program data fix at the time of compilation.

Byte Code

" Middle level output of a compiler "

High level languages like (C,C++,Java,C#) are easy to code , Programmer write code using a text editor or IDE provide by related language compiler called source code.

Source code cannot run direct by computer it need to be transform into machine language by compiler.
