What are the difference between computers 1 generation to 5 generation?

1st Generation (1940s-1950s): Vacuum Tube Based

* Key technology: Vacuum tubes

* Size: Room-sized

* Processing speed: Few thousand operations per second

* Storage: Magnetic drums, punch cards

* Input/output: Teletype machines, punch card readers

* Examples: ENIAC, UNIVAC I

2nd Generation (1950s-1960s): Transistor Based

* Key technology: Transistors

* Size: Smaller; could fit in a standard cabinet

* Processing speed: Tens of thousands of operations per second

* Storage: Magnetic core memory, magnetic tapes

* Input/output: Teletype machines, card readers, printers

* Examples: IBM 1401, PDP-1

3rd Generation (1960s-1970s): Integrated Circuit Based

* Key technology: Integrated circuits (ICs)

* Size: Even smaller; could fit on a desktop

* Processing speed: Millions of operations per second

* Storage: Magnetic disks, floppy disks

* Input/output: Keyboards, monitors, mice

* Examples: IBM 360, DEC PDP-8

4th Generation (1970s-1980s): Microprocessor Based

* Key technology: Microprocessors

* Size: Personal-sized; could be carried around

* Processing speed: Tens of millions of operations per second

* Storage: Hard disks, floppy disks, optical media

* Input/output: Keyboards, monitors, mice, graphics adapters

* Examples: Apple II, IBM PC

5th Generation (1980s-present): Advanced Microprocessor and AI Based

* Key technology: Advanced microprocessors, artificial intelligence (AI)

* Size: Even smaller; could be held in the palm of the hand

* Processing speed: Billions of operations per second

* Storage: Solid-state drives, cloud storage

* Input/output: Touchscreens, voice recognition, gesture control

* Examples: Smartphones, tablets, laptops
