What is programming language?? It is medium for communication. we, human being need language to communicate between us. Similarly, to communicate with computer we need language and we call them programming language. The computer understands binary/machine language i.e. A language made up with combination of zeros and ones. It is impossible for human to understand such difficult language. In result, we have programming languages which we can understand partially. These languages will be converted to machine language using some other program (using Compiler or Interpreter) in order to instruct the computer or system. Based on the human understanding we have following types of languages. Please note as we are moving down understand-ability of human will be strong and understand-ability machine will be weak. 1. Binary Language (Machine Language): Binary stand for two, the computer understand this language, it is made up with combination of two elements zero's and one's. OR a lan...

Hello Programmers, every programmer must know about Compiler, Interpreter and Assembler as a programmer if we know programming languages, we can't interact with computer directly becauase computer understand Binary Language. In order to communicate with computer we required mediator (translator) between computer and we human . the programme gives instruction in programming language which he knows, then translator convert it into machine language according to instruction. Translator: It is System Software( it is nothing but program which it design either to run hardware or our application program) which is use to convert programming language code into machine, Translator classified into three types 1. Compiler Compiler is system software which is use to convert programming language instruction into binary language in single step. i.e when you compile your program compiler check all instruction of a program and generate machine code for that instruction which are syntactically cor...

You may have doubt, why we are using such difficult language(Difficult to understand) if we have High-level languages like Java and .Net. When the computer starts it loads Operating System from Hard disk to RAM(Random access Memory), To load OS we need Program called BIOS(Basic Input Output Software) program.The BIOS is a kind of System Software.Such programs are written in languages like C. If you connect a printer or any other hardware to computer first time it prompts message "installing required software". Device Driver is Program which required if we connect an external device to our Computer. Such Device Driver software coded in Languages like C. Artificial Intelligence is Technology (making machines which behave like human) we need certain programs for such devices, these programs written in the programming language like C. As you know computer can understand binary language, we need to convert our Program written in any Programming Language to binary language, It ...

Hello Programmers, Every Programmer should know this about the programs and programming languages and software. Software is collection of programs, 'n' Number of Programs combine together like a single unit call Software Program is set of instruction to perform Particular task. compare your program with a paragraph. As we have Sentences for Paragraph, In same manner we have Instruction for Program. Instruction means 'tell to do something'.as teacher gives instruction to student,, In same manner we human instruct to computer. What is a language?? It is medium for communication. we, human beings need language to communicate between us. Similarly, to communicate with computer we need language (programming language). As computer understand zero and one and it is impossible for human to understand such language,, we need another language which both can understand,Practically it is impossible,, Result is we have Programming languages which we can understand(not completely...
