So you know what a CPU is. But how the heck does it work?
Well, you also probably know that a CPU is made out of transistors, which are basically tiny switches, more on that later.
These transistors are the essence of ultra-fast and powerful computers, and what allow them to load and process information in fractions of a second.
So what are transistors made out of? Transistors have a semiconductor base, which is then doped (specific elements added) to allow it to better conduct electricity in certain places.
These two places are separated from each other by the in-doped part of the transistor, and the conducting parts must have some sort of conductor in between them so that they may have a conducting channel.
But by themselves, they cannot conduct electricity, because there is no electricity source. So then two more conductors are attached to the metal bridge, with one being the source, and the other one being the drain.
When electricity is conducted through it, it is in the “on” state, and when it isn’t, it’s in the “off” state. The brilliance of this design is that we can create them almost infinitesimally small, because there are no moving parts. If there were, they’d probably only be a couple atoms wide.
When the transistor is in the on state, it can be considered as sending out a 1 signal. When it is off, it can be considered to send a 0 signal. With millions and billions of these transistors working together, they can form massive strings of 1s and 0s, which the computer then might translate as images, numbers, or videos.
That’s basically how a CPU works!
