A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function and typically executes the program’s instructions in a central processing unit.A computer program is usually written by a computer programmer in a programming language.
Computer language or programming language is a coded syntax used by computer programmers to communicate with a computer. Computer language establishes a flow of communication between software programs. The language
enables a computer user to dictate what commands the computer must perform to process data. These languages
can be classified into following categories :-
1. Machine language
2. Assembly language
3. High level language
Machine language is a computer programming language consisting of binary or hexadecimal instructions which a computer can respond to directly.
Assembly language is a low-level programming language for a computer, or other programmable device, in which there is a very strong (but often not one-to-one) correspondence between the language and the architecture’s machine code instructions.
High level language is a programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages.
