1st GenerationVacuum Tubes (1946-1958)
• Speed 50 mutiplications per second
• Input/output cards and punched tapes
• Good memory type relays
• 1950 computers had dvum memory
• Held one million bytes
• Stored as many as 4,000 words
• 1952 people were feeling the pop culture
1st Generation con’t
2nd Generation Transistors(1959-1964)
• Changed the course of history
• Composed of semi-conductor material
• Transformed the world of electronics
• Used transistors instead of vacuum tubes
• Both had the same functionality
• Invented in 1947
• Nobel Prize 1956
2nd Generation con’t
3rd GenerationIntegrated Circuits(1965-1970)
• Radio frequency
• Volume issues
• Transistors were miniaturized
• Created keyboards and monitors
• Was interfaced with an operating system
• Became accessible to a mass audiencecharacterized by a major technological development
3rd Generation con’t
4th GenerationMicroprocessor (1971-present)
• Down sized
• Combined two enhanced third generation cores
• Memory design was updated
• Hardware additions feature expanded caches
• More refinement than complete redesign was accomplished
4th Generation con’t
• Microprocessor it’s characteristic of this generation computer
• Ten years later,65million were being used
5th GenerationPresent and beyond
• Began in 1982
• Ipods and different models
• Has a large amount of storage
• Comes in different shapes and colors
• Has a touch screen
• Can connect to the computer
5th Generation con’t
