1) 1940 – 1956: First Generation – Vacuum Tubes

Characteristics of 1st Gen computers
Used vacuum tubes for circuitry
Electron emitting metal in vacuum tubes burned out easily
Used magnetic drums for memory
Were power hungry
Were expensive to operate
Solved one problem at a time
Used machine language

2)1956 – 1963: Second Generation – Transistors

Characteristics of 2nd Gen Computers

Used transistors
Faster and more reliable than first generation systems
Were slightly smaller, cheaper, faster
Stored data in magnetic media
Were still costly
Generated heat though a little less
Still relied on punch cards and printouts for input/output

3) 1964 – 1971: Third Generation – Integrated Circuits

Characteristics of 3rd Gen Computers

Used ICs
Used parallel processing
Were slightly smaller, cheaper, faster
Used motherboards
Data was input using keyboards
Used operating systems, thus permitting multitasking
Simplified programming languages i.e. BASIC

4) 1972 – 2010: Fourth Generation – Microprocessors

Characteristics of 4th Gen Computers

Used CPUs which contained thousands of transistors
Were much smaller and fitted on a desktops, laps and palms
Used a mouse
Were used in networks
Were cheap
Had GUI
Were very fast

5) 2010- : Fifth Generation – Artificial Intelligence

The main features of fifth generation computer

ULSI technology
Development of true artificial intelligence
Development of Natural language processing
Advancement in Parallel Processing
Advancement in Superconductor technology
More user-friendly interfaces with multimedia features
Availability of very powerful and compact computers at cheaper rates
