Generations of Computers

FIRST  
GENERATION 
COMPUTER (1951-1958)

In 1951 the first generation of computer started with the UNIVAC I which stands for Universal Automated Computer built by J. Presper Eckert and John Mauchly I have a research   about them and i found out that they are the founder of EMCC (Eckert-Mauchly Computer Corporation)who designed the first commercial computer in U.S (United State) and the inventor of ENIAC or the Electronic Numerical Integrator and Computer it is the first general purpose electronic computer.UNIVAC I  is sold to the US Census Bureau. It is dedicated to business data processing so i thought it is only for business matter and not for military or scientific purposes.Its characteristic is it use vacuum tubes in electronic circuit which controlled the internal operations and this vacuum was huge.so the consequence is the machine is also large like in the picture above. 

SECOND GENERATION   

COMPUTER (1959-1964)

Not like First Generation Computer that use

vacuum tubes for internal operation.The Second Generation Computer use a tiny solid  state transistor like you saw on the picture.but the good about it the heat problem was minimized and the computer could be made smaller and faster.i thought that because of the tiny solid transistor computer can be smaller and faster not like vacuum tubes that are so huge and the computer was also huge.

THIRD
GENERATION
COMPUTER (1955-1970)
The use of IC (Integrated Circuit) replaced the old tiny solid transistor of the second generation computer this circuit are printed and hundreds of electronic components could be put on silicon circuit.like tiny solid transistor IC or integrated circuit has greater storage capacity..

FOURTH 
GENERATION
COMPUTER (1971-Present)
A Fourth Generation Computer is a modern day computer.so its more faster and more reliable to a specific task and has a greater amount of storage data. and the size started to go down with the improvement in the integrated circuits.it use a very large scale that many component could be fit in a small chip.it reduced the size and price of the computer at the same time increasing power and reliability. .The intel chip developed in 1971 took the integrated circuit one step further by locating all the component of a computer.

FIFTH 
GENERATION 
COMPUTER (1982-Present)
All of our computer in our home are fully developed when it comes in faster processor and much greater storage capacity not like 1st to 4th generation i thought this computer is capable of course and more convience to  our needs when it comes in doing your  project or research or even surfing the  internet,multitasking and private business purposes.thats why we are lucky to have this kind of computer which is very useful to us in our daily routine.
