In early century people face a tough time where they have to solve complex problem without any machine. So, they founded a machine which was technically called “COMPUTER” Generations of Computer People design computer which meets their necessity. It is divided into five types such as 1. First Generation Computer( Vacuum tube) 2. Second Generation Computer(Transistor) 3. Third Generation Computer(Integrated Circuit) 4. Fourt
