Moore's law
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

what type of memories in the memory
ROM (Read only memory) RAM (random access memory)
36
ROM (Read only memory)
where the basic instructions are going to be
37
RAM (random access memory)
main memory where software and data is gonna be found
38
what happens when RAM is full?
it makes computer appear slow
39
what do you do to make computer go faster when RAM is full?
you add memory (RAM)
