Why so much transistor in a processor ?

Question

How increasing number of transistor increase the power or speed of processor ? We know transistor have two modes(on or off) . Does all the transistor of a processor stays at same state at a particulal time ? If the answer is positive then only one transistor should be enough for a processor to process data . If answer is negative then how the transistors is in different state at a time while processor get 0or1 as input signal at a time . Processor get 0or1 as input signal at a time ; whats the output when input is 0. Answer me the same question when input is 1.

Answer 1

Transistors are grouped together to form logic gates. To answer your question, not all of the transistors are in the same state at the same time. By switching different gates on and off, you change the path of the signal through the processor (you literally create a new circuit). Following a different path through the microprocessor gives you a different output.

Answer 2

each and every IC has such countless PNP & NPN semiconductors interior.So there ought to correctly be a lot. yet somewhat that is previous mind's eye to carry close thousands and thousands of transistors are interior a processor. thanks for this ideas.

Answer 3

Generally more transistors give you more logic that can be performed. A modern processor will divide instructions into many subparts and run them in parellel... thus it will take less time per instruction and increasing the overall speed. The other way to do it is to increase the clock frequency, but that has disadvantages to increase power consumption (as shown from the Pentium 4)
