A machine language is a low-level language. It is tedious, difficult, and time consuming to develop
programs using machine language.

Second-Generation Programming Language (Assembly Language)
The Second-generation programming language is the
Assembly language. In this language, mnemonic codes
are used to develop a program. Mnemonic codes are
short words used for a lengthy set of instructions.
Programming in assembly language is simpler and
less time-consuming than programming in machine
language. It is also easier to locate and correct errors
in assembly language.

Assembly language programs are also machine-dependent. An assembly language is also a low-level
language because detailed knowledge of hardware is still required.
In order to execute an assembly language program, you need to convert it into an equivalent machine
language program using an assembler.
Assembler
An Assembler is a language processor that converts an
assembly language program into a machine language
program. Each instruction in assembly language is
usually converted into one machine instruction.

Knowledge Discovery Subject Enrichment

The program written in any programming language other than machine language is called source code. The
program in machine language, executed directly by a computer, is called object code.

Third-Generation Programming Language (High-level Language)

A Third-generation programming language (3GL) is also known as
high-level language. It is a programmer-friendly and structured
language, similar to the English language.
High-leveI language programs are machine-independent. Programs
written for one computer can be executed on another computer.
Some examples of third-generation programming languages are C, Third-Generation Languages
C++, Python, and Java.

In order to execute a high-level language program, you need to convert it into machine language,
either by using a compiler or an interpreter. Each high-level language requires its own compiler or
interpreter.

Compiler
A Compiler is a language processor that
converts a high-level language program Source Code Compiler Machine Output
Code
into a machine language program, in one
go. It first scans the entire program and then How Compiler Works
