History of Computers

Generation	Examples of Computer	Electronic Components	Years	Used for?	Size	Interesting fact about each
1	Colosssus ENIAC	Vacuum Tubes	1942 - 1963	Scientific calculations and decryption	Took up  a Room	Vacuum tubes can go for more than $50 today!
2	TRADIC UNIVAC	Transistors	1953 - present	calculations and aircraft bombing troubleshooting	About the size of three fridges	The UNIVAC was one of the fist computers to use solid state components (did not move)
3	555 Chip 556 Chip	Chips (Integrated Circuits)	1949 - present	Calculations, storage, and much more.	Fits in the palm of your hand	The first IC was made by popular calculator company Texas Instruments.
4	Intel Pentium Intel Core Duo	Microprocessors Computers on  a chip	1971- present	Personal use and INTENSE CALCULATIONS	Slightly larger than the IC	This era is when personal computers became standard.
5.	Modems Servers	Networking Parallel Computing Fibre Optics	1991 - present	Pretty much anything.	Occupies multiple spaces	Tim Berners-Lee invented the Internet for his colleagues at CERN.
