Q

Moore’s law

A

a guide developed by Gordon Moore

a graph illustrating how microprocessors have been evolving

relates to thin crease of number of transistors increase over time

in his law, it is explained that the number of transistors increases approximately every two years due to technological advancements

computers get more transistors with these getting smaller and smaller, making computers OP

microprocessors are getting cheaper
