We all know the core of the computer is the main material of the CPU is made of silicon material, since last week, we talked about the operating system, I have a CPU stripping the impulse, between its high price, also can not find the discarded cup, the idea has been shelved. I just don't understand, a string of binary 0 and 1 code, give a piece of processed silicon, it will be able to return you a string of binary code. Later asked to learn the hardware of the Liao, said that the different intensity of the current represents 0 and 1, and then I will understand the point. Today look at the classmate blog, by looking for some information, is temporarily resolved my doubts it.
Here's how the transistor works (just one aspect of it):
The s in refers to the source, D is the drain (Drain), and G is the Gate (gate). Transistors work in a very simple way, with two states representing binary "0" and "1".
Between the source and the drain is the channel (channel), when there is no voltage applied to the gate (G), the channel does not gather an effective charge, the source (s) and drain (s) between the effective current generation, the transistor is closed. This closed state can be interpreted as "0".
How the Transistor works
When a voltage is applied to the gate (G), an effective charge is gathered in the channel, forming a passage from the source (S) to the drain (D) and the transistor is turned on, which can be interpreted as "1". In this way, two states of the binary are represented by the opening and closing states of the transistor.
How the Transistor works:
And then you ask, what is a transistor made of? And then you find the term semiconductor, the common semiconductor in the market is silicon, and the characteristic of semiconductors is that it can be controlled by its conductivity.
And then add the rice teacher said the role of the address line, I understand why you give the CPU a piece of binary code, it will give you a string of binary code!
I said I understand the point, the next understanding must be different from the present understanding, the first such, continue to understand!
Summary: Learn this thing, like Rice teacher said, only to find the answer, to better grow! Can't wait to be. This is the space for me to ascend later!
