         Generation in computer is growth of a step by step Technology. Originally that term generation was used to distinguish between hardware and software. Technology which gradually changed during that period of time. In Computer technology hardware and software extended. There are totally five computer generation known until today.                            Each and every generation has been distinguish below in detail along with its identifying characteristics :- 1. First generation of computer (1942-55)   The first generation of computer were vacuum tube based machine. These valves Greatly large. Each was able to hold only a single bit. In fact the first generation computer using vaccum tube as a CPU component. It was only high speed switching device available in those days. First generation use machine language and Assembly language for programming. In this period first...
