The History of Computers

Computers started out as mechanical calculators.  They could do math by digitizing on/off switches and perform calculations based on pages and pages of program.

 They would take up a room and only really have motherboard, ram, and CPU. Graphics were added later and were basic. The color of a pixel was considered artistic. Now, graphic cards have GPU (graphical processor), hard drives (instead of printed information). Lets not forget keyboard and mouse. While ago you would build a room for a computer. Now, you build the entire house with computer in mind. We are now building digital wall paper, and hooking up the internet to everything.  Now, everyone has a personal secretary on their phone.  Computers evolve and are now adapting to quantum mechanics do to calculations. Instead of the on/off confirmation for calculations it brings in the possibility of if.

I will end with another evolution in computers. This lady recently designed a program for black holes :
