This is a basic tutorial on how transistors actually make and take those ones and zeros and convert them into data for the PC. First of all you need to know that all those 1's and 0's are not just scrambles up and put into a bag.
By now you have herd of bytes and bit's well those are clumps of data that are apart of a larger command string that you will probably never see. Most of that data is a map that navigates through your CPU and eventually reach its destination. The CPU then executes the command that was given, whether it is data for a picture or a virus.
But then the question is asked, "How does the transistor do all that?" Well this is how. It is far simpler then you might think, but it can get way too complex.
I will first start off describing the transistor in simpler terms, if you need more complex instructions, just ask by E-mailing me.
The basic "PNP" transistor is composed up of three parts, two positive materials separated by one negative material.
The trick of the game is to get current flow across the transistor from the emitter to the collector. But there is a catch; current cant flow across until a voltage is applied to the base. That is it.... Now this might sound a little stupid but that is what adds, subtracts, devides, exc. It's true!
There are also some other rules like current cant travel back from collector to emitter or Base to Emitter, but this allows us to do so much with out many realizing it. For example , if you align the transistors in various patterns then you will be able to produce some functions called "gates" these gates include the And Gate, Or Gate, Not gate and much more but are really minor alterations to these three basic functions.

The following picture above are the basic AND Gate; this gate is composed up of three transistors. Its basic purpose is when there is a logical 1 at A and B then C will be a logical 1. Only when these conditions are met will C be a logical 1 and with no other combination of A and B. In any other case like A = 1 and B = 0 then C will = 0.

Believe it or not, this "simple" circuit multiplies numbers. Look at the Truth table, A is grey, B is red and C is blue. If you multiplied the A and B, you will always get the right answer in the C box. This strange phenomenon is also with the OR circuit, it is said to be an "ADD Gate" although the Or gate does not have any transistors, it still serves a great purpose like the And Gate. You should try not to think of these 1's and 0's and numbers but representations since all the numbers and letters an your screen are coated and decoted using a byte or combinations of those 1's and 0's. You can look at it as you leave the voltage left on the B input of the AND gate, next you let some data in through the A input but you decide that you want to stop the command, you simply change that B input to a zero and C will = 0 I should also note that time has a great deal of importance. There is a circuit on every computer that is said to be your CLOCK. This circuit is a crystal that has a very frequent and reliable pulse of electrons, this circuit allows order and synchronous of these circuits for when they want to store information, yes, the AND OR's and NOT gates can be used to store information. But these storing devices known as flip-plops, which require a timing circuit.
With this knowledge, it is important to know that your computer does not function with out some king of instructions, you can say that your computer is an answer box and you have to ask it questions like "when I press the enter key are you going to lock up?" Some times the computer says yes.
