How can the Linux kernel compile itself?

Question

I don\'t quite understand the compiling process of the Linux kernel when I install a Linux system on my machine.

Here are some things that confused me:

The term describing this phenomenon is bootstrapping, it's an interesting concept to read up on. If you think about embedded development, it becomes clear that a lot of devices, say alarm clocks, microwaves, remote controls, that require software aren't powerful enough to compile their own software. In fact, these sorts of devices typically don't have enough resources to run anything remotely as complicated as a compiler.

Their software is developed on a desktop machine and then copied once it's been compiled.

If this sort of thing interests you, an article that comes to mind off the top of my head is: Reflections on Trusting Trust (pdf), it's a classic and a fun read.
