Physical Memory
就是实际的内存条提供的临时数据存储空间，在windows上右键点击计算机，显示属性时，上面显示的安装内存(RAM)，就是电脑的物理内存。这些内存是实际存在的，在你不给机器增加内存条的时候是不会改变的Swap memory
交换内存是专门用来临时存储数据的，通常在页面调度和交换进程数据时使用。相当于在进行内存整理的时候，会先把部分数据放在硬盘的某个地方，类似我们整理衣柜，衣服一多直接整理会很麻烦，因此会先把部分衣服放在其他地方，等衣柜里的衣服整理完了再把放在其他地方的衣服拿回来。这个其他地方放在计算机中则代表硬盘的某个地方，也就是我们所说的交换区。通常当使用交换内存时，以为这物理内存不足，正所谓衣柜，如果衣服不多那就没必要拿出部分衣服放在其他地方，直接在衣柜里就能解决了Virtual Memory
首先，如果想要操作文件，可执行程序等等，那么首先要把它们从磁盘上读取到内存中，因此cpu除了自己的那一部分小小的空间外，要想操作数据，只能操作内存里的数据。但是当内存不够了，那么便会在硬盘上开辟一份虚拟内存，将物理内存里的部分数据放在虚拟内存当中。硬盘的空间很大，即使普通电脑安装的固态硬盘也有一百个G，因此可以拿出一部分充当虚拟内存。不过虚拟内存虽说是内存，但毕竟在硬盘上，速度绝对和cpu直接从物理内存里读取数据的速度相差甚远。这也是为什么那些大型网站将经常被访问的一些数据放在redis缓存里，而不是放在硬盘或者数据库上
