How TRANSISTORS do MATH

Learn how a computer adds numbers in one lesson. Inside the computer you will find the motherboard. The motherboard acts like a chassis inside a car, giving all the components something to connect to. The microprocessor is on the motherboard. Most microcontrollers have a heat sink on top to prevent overheating. If you remove the microcontroller and look underneath, you will see many wires sticking out of the holes on the motherboard to the main microcontroller. The microcontroller is made of different areas that do different things, such as adding or storing numbers. These areas are often made of a single thing.

The transistor. Here is a 3D illustration of one of them. The base of the transistor is made of a semiconductor, which sometimes conducts electricity and prevents it at other times. The semiconductor has charged areas with a positive charge and charged areas with a negative charge. Electricity will not flow between the yellow areas unless the green conductive area is opened. The conductive area will open up in the semiconductor if you place a conductive material like metal on top of the gap, cover it with an insulating material like glass, and charge it. With electricity, in order for electricity to flow through the channel connecting the two yellow areas, there must be a source and an outlet (outlet).

That is, an input and an output are also made of conductors. If the input is charged, the output cannot be charged unless the gate, which is the piece in the middle, is charged. The hatch was open. It opened the conductive channel in the semiconductor, allowing electricity to flow toward the source, on the other side of the semiconductor, to the mouth. The creative thing about this is that there are no moving parts and electricity alone is used to control electricity elsewhere. The idea was to use it to make logic gates. For example, if you have two conductors and connect electricity to the input of each conductor, then add a switch to each of the gates, and then allow the outputs to flow directly to a lamp, you have created an "o" gate, which has this symbol.

Open the left switch, or open the right switch, or even Both, to obtain lamp illumination if you change the connection method, so that the output of the first connector connects to the input of the second connector: thus you have created a door "y", which has this symbol with the door "y". If you open the switch only to the left, the lamp will not turn on. Because the electricity coming from the first conductor has stopped at the second conductor. If you open only the left switch, the lamp will not turn on. Because no electricity flows from the first conductor to reach the input of the second conductor.

Therefore, so that the lamp does not turn on, both switches must be turned so that the output is open, as well as open and closed, they can be represented by the switches as: closed (0) and open (1), the same as the light bulb, open and closed, zero and one, zeros and ones are computer language and create their own number system called “binary system” or binary. Let's start counting using the decimal number system, and write down any binary number. We find in another language any number that has a zero and a one. So to start we write down the zero because it contains a zero or a one, and also the one.

We must skip the other decimal numbers until we reach the number 10, and eleven also works, twelve does not work for the rest either. of the numbers. In fact, now we have to jump to tens because we won't get a zero or one until the number 100, and then it's 101, then nothing until the numbers 110 and 111, and we won't find one. and zero again until we reach the number 1000. Well, we move that 1000 to the bottom and continue counting binary numbers.
