Memory
This is the amount of real physical memory that this process is using by itself, and approximates the Private memory usage of the process.
It does not include any swapped out memory, nor the code size of its shared libraries.
This is often the most useful figure to judge the memory use of a program.
Shared Mem
This is approximately the amount of real physical memory that this process's shared libraries are using. This memory is shared among all processes that use this library

纠正一下,之前网友的回答是望文生义,根据汉语名称进行解释。实际上,只要看看“系统监视器”的帮助,就知道不是这样的,下面是帮助中关于进程使用的“内存”与“共享内存”的解释,直译过来的大概意思是(不准确,本人并非计算机专业,名词翻译可能有不妥之处):共享内存是每个进程使用的一些“库程序”所占有的内存,可能被其它使用这些“库程序”的进程所使用。

内存是你的实际内存
共享内存指在多处理器的计算机系统中,可以被不同中央处理器(CPU)访问的大容量内存。由于多个CPU需要快速访问存储器,这样就要对存储器进行缓存(Cache)。任何一个缓存的数据被更新后,由于其他处理器也可能要存取,共享内存就需要立即更新,否则不同的处理器可能用到不同的数据
共享内存 (shared memory)是 Unix下的多进程之间的通信方法 ,这种方法通常用于一个程序的多进程间通信,实际上多个程序间也可以通过共享内存来传递信息。
