    There are two categories of low-level languages:

                     Machine Language
                     Machine language is the only language understood by the computer. It is also known as the first

                     generation language (1GL). Machine language is very difficult for programmers to use because
                     it only consists of two digits, 0 and 1, called binary digits or bits. Where the bit ‘0’ represents the
                     OFF state and the bit ‘1’ represents the ON state.

                     Assembly Language
                     Assembly language is also known as second-generation language (2GL). It is the language in
                     which program codes are written in the form of alphanumeric symbols called 'Mnemonics Code'
                     instead of 0 and 1. In the assembly language, a programmer writes abbreviations such as A for
                     addition, C for compare, L for load, M for Multiply, etc.

                     HIGH-LEVEL LANGUAGE
                     High-level  language  is considered  to  be closer to  human beings.  It is machine-independent
                     language.  However, they need  to  be  translated  into  binary  or machine  language.  Programs
                     written in high-level languages are called source code. Since the computer understands only 0s
                     and 1s, all high-level languages require a software called language processor or translator to
                     convert the instructions into machine language are also called object code. Let’s discuss about
                     some high-level languages.

                     Third-Generation Languages (3GL)
                     In  third-generation languages (3GL), the programmer writes a series of English like words
                     that tell the computer what to do and how to do it. Many third-generation languages also use
                     arithmetic operators such as * for multiplication and + for addition. Some early procedural 3GL
                     are BASIC, PASCAL, C and FORTRAN. C++, Java, C#, and other advanced object-oriented 3GL
                     languages are also available.

                     Fourth-Generation Languages (4GL)
                     The  fourth-generation  languages  also use English-like statements.  They specify  what the
                     program should accomplish without explaining how. 4GL is fast and requires less time and effort
                     on the part of the programmer. In fact, 4GLs are so easy to use that programmers with very little
                     programming background can develop programs. Examples of 4GL are SQL, Perl, Python, etc.

                     Natural Languages (5GL)
                     The  fifth-generation  languages, also known as natural languages  are the  programming
                     languages that have visual tools to develop a program. Examples of fifth-generation languages
                     include Mercury, OPS5, and Prolog. Natural language is very easy to use. Natural languages are
                     often associated with expert systems and artificial intelligence.
