History of computers

Consider the table below:

Generations Of computersYear of developmentThe Technology UsedCharacteristicsSoftware InstructionStorage Capacity
First1951-1958    Vacuum tubeVery big and slow in operationMachine languageSmall internal storage
Second1959-1964TransistorLess heat generationHigh level & AssemblyCore storage
Third1965-1975100-1000 ChipsIntroduction of integrated circuitMultiprogramming FacilitiesInternal
Fourth1975-19821000 aboveVLSICIntroduction of Non-procedural languageFlexible internal & external storage
Fifth1982 and above106chipsAI and Expert systemIntroduction of object oriented programming languageSmall but powerful network
