Faster stuff costs more per bit. So you have a descending chain of storage, from a few registers at one end, through several levels of cache, down to RAM. Each level is bigger and slower than the one before. And all the way at the bottom you have disk.
寄存器和高速缓存位于 CPU 芯片本身上，或者与其紧密相连。普通 RAM 是通过地址总线访问的，并且通常受到内存映射的一定程度的间接访问。
Registers and cache are on the cpu chip itself, or tied to it very closely. Normal RAM is accessed through an address bus, and it often subject to a level of indirection by memory mapping.

更快的东西每比特的成本更高。因此，您有一个递减的存储链，从一端的几个寄存器，经过几级缓存，一直到 RAM。每一层都比前一层更大、更慢。一直到底部你就有磁盘了。
