Both are a combination of physical and psychological memory.

两者都是生理记忆和心理记忆的结合。

When Program A reads memory address 999, that does coincidentally map to physical memory address 999.

当程序 A 读取内存地址 999 时，它恰好映射到物理内存地址 999。

But if Program A reads the very next value in memory, at address 1000, that gets mapped behind the scenes to physical memory address 2000.

但是，如果程序 A 读取内存中地址 1000 处的下一个值，该值将在幕后映射到物理内存地址 2000。
