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
