Five Generations of Computer - Learn Computer with Praveena

First Generation - 1940-1956

   VACCUM TUBES

                             The  First generation of Computers used Vaccum Tubes for circuitry and magnetic drums for memory. Input was based on punched cards and paper type, and output was displayed on printouts.

• Large in size
• Occupied a lot of space
• Produced enormous heat
• Very expensive
• Consumed large amount of electricity
• Operated only on machine language 

Second Generation -1956-1963

      Transistors

                        The Transistor was far better compare to Vaccum tube, in transistor punch cards for input and printouts for output

• Smaller
• Faster
• Cheaper 

Third Generation 1964-1971

                     Integrated Circuits

                           In this third generation , keyboards and monitors were used , it solves so many problems at a time.

• 
  

Fourth Generation - 1971-2010

             Microprocessors

                   Thousands of integrated circuits were built onto a single silicon chip.

• Speed
• Accuracy
• Reliability
• Smaller in size 

 Fifth Generation - 2010- Present

              Artificial Intelligence

• Able to recognize image and graphs.
• Decision making
• Logical reasoning
