Low Level Language
It is a machine level language
computer only understand digital number i.e.
In the form of 0s and 1s. So, instruction given
to the computer is in the form binary digits, which is difficult to implement instructtion in binary code. This type of
program is difficult to maintain and also error prone.
Middle Level Language
Where Instruction are given in English like word as ADD,SUM,MOV and symbol like ?,><* etc. It is easy to write and understand as compare to machine language but not understand by the machine. So the translator usd here is Assembler to translate into machine level. Although Language is bit easier but programmer has to know low level details related to low level language as Assembly level Language the data are stored in the computer register, which varies for different computers. Hence it is not Portablel.
High Level Language
High level language are NoT understand by the machine
directily. So it need to translate by the translator into machine level. But
High level language are human friendly as
they use the terminology of human language. These language are machine
independent, means it is portable. The
language in this category are C++, Java, Pascal,
cobol,Fortran etc.
