machine called Difference Engine .
Evaluate accurate algebraic expression and
mathematical, This machine is also called as
Babbage's difference engine, Later
modified the device as Analytical Engine .

electro-mechanical computer developed by Howard Aiken.
38. Plenary/Recap
Advantages :
•It makes it easier to find information and faster to find it.
•more efficient, then they used to be.
•it makes it easier to talk to friends on social web sites.
Limitations :
•can be very slow
•it might not find the exact information you need, or it might give
you something you don’t need.
