Programming Languages:-
Programming languages are the
software used to give instructions to a machine. We know that computer is a
machine that only understand 0 and 1. all programs are written in programming
languages that translate the codes into machine language and tell the computer
what to do. There are two types of programming languages.
Low level Programming Language:-
High Level Programming Language:-
Low level Programming Language:-
High Level Programming Language:-
Low
level Programming Language:-
A low level programming language
generally machine code. only a computer (machine) can understand it. It is very
difficult for human to understand it
High
Level Programming Language:-
A high level programming language is
specifically written in a language that is easily understood by human. In order
to make it understandable for a machine special software are used these
software are as followed.
Assembler: An assembler is a software that translate the assembly
language program into a machine code.
Compiler: A compiler is more powerful then an
assembler because it translate a High level language's program into machine
code. it also checks for errors in a program.
Interpreter:An interpreter is a program that translates the each
statement of a program into machine code one by one. As it translates only one
statement of the program at a time it works very slow.
Linker: High level languages include some built in header files or
libraries. These libraries contains some predefined functions, these basic
functions which are essential for executing the program. These functions are
linked to the libraries by a software called Linker.
Loader: Loader is a program that loads
machine codes of a program into the system memory. Most often these programs
are part of an operating system. Operating system is responsible for starting a
program.
