Introducing C#, C-Sharp, History of Languages, History of C#,

Computer languages have come a long way since the 1940s. Back then,
scientists punched instructions into mammoth, room-sized computer systems. These
instructions were long series of zeroes and ones. These machine language
instructions are called the First Generations of computer languages.

The 1950s saw the emergence of the Second Generation of computer languages -
assembly language - easier to write than machine language but still extremely
complicated for a common man. However, the computer could still understand only
machine language. Therefore, the Assembler software was developed to translate
the code written in assembly language into machine language.
