MOTHER TONGUE OF A COMPUTER:
Everyone of us knows at least one or two human languages such as English ,Urdu ,Chinese .One of there is our tongue , the language which we learned from childhood . Similarly , computer have their own "mother tongue ". The mother tongue of a computer is machine language.
Machine language instructions are in binary form.
computer language
(1) A programming language or machine language.
(2) Everyday computer language, which includes computer technologies and concepts as well as hardware and software products .
MACHINE LANGUAGE ADVANTAGES :
Machine language program is written is machine code.This is the only language that the computer can understand directly . The main advantages of machine languages are:
Machine code is carried out faster as it is the "native language" of the computer.
It occupies less momory space.
DISADVANTAGES :
However , it has the following disadvantages:
Each type of computer has its own set of instruction codes so each machine work on
only one type of computer.
Its very laborious to write programs in machine codes. Programs in machine code
are also difficult to decode and modify.
There was a time when programmers had to write programs in machine language.Now programmers can use programmiong language.We will look into programming languages next.
TYPES OF PROGRAMMING LANGUAGE:
We can write a program in a programing language and then translate it into a machine language look at the simple program written in a programming language called BASIC .This program tells the computer to find the area of a square and display the answer on the screen
10 Rem Calculate The area of square
20 Let side = 12
30 AREA =Side * Side
40 Print AREA
As you can see .the program statemnet are easier to read , unlike the machine code .A program written in any one of the programming languages is called the source code,The source code has to be translate to machine code before it can be executed. We need a computer translator for this purpose.The machine code is save as an executable file.The executable program file is called the object code.
A COMPUTER TRANSLATOR:
A computer translator is yet another program. Its function is like that of a human tanslator.Ahuman translator or
interpreter who knows both English and Urdu can help a Pakistani and an Englishman to converse.
TYPES OF COMPUTER TRANSLATORS:
There are two types of computer translators :
Interpreters
Compilers
INTERPRETERS:
An interpreter is a program that translates and executes each source code statment before translating and executing the next statment.
COMPILERS
Compiler is a program that translate all the source code statment before it executes the program.

In computer language what does the word progra mean?
In the computer language the word "progra" is short for program. The word "progra" is shorthand or slang for the word program in the computer language.
What is the difference between computer programsand computer applications?
An application is a program
What is the difference between an algorithm and a computer program?
What is the difference between a computer and a computer program?
A computer is an electronic (or electromechanical) device that can handle input, processing and produce output. A computer program is a set of rules or instructions that enables the computer to perform these tasks (input, processing and output). They work together, a computer is useless without a computer program, and a computer program cannot work without a computer. It is a symbiotic relationship.
How does programs works in a computer?
Computer programs are usually made with a programming language such as Microsoft C++. A ton of coding goes into a single program

Differences between source program and object program?
SOURCE PROGRAM=A set of instructions of the high level language used to code problems to find its solution on a computer is referred as source program. OBJECT PROGRAM=The computer translates the source program into machine language program called object program by using an interpreter or compiler is called object program.

What are the differences between program and program language?
Programming [verb] is a process done by software engineers or computer programmers consisting of the following steps: customer requirements analysis, software design, coding the design using a programming language, testing and debugging the program parts, program integration, testing and debugging the complete program, and customer acceptance testing. Any bugs found during the two testing steps of the programming process will have to be fixed in the code written in the programming language and all necessary testing steps repeated.A programming language [noun] (you wrote program language) is a human readable language used by software engineers or computer programmers during the coding step of the programming process. The code written in the programming language is then converted by a translator program (e.g. compiler, assembler) to machine code that the target computer can "understand" and run.
