恩.
給你一點閱讀功課...
節錄其中一部分重點,
如果你真的懶於閱讀的話.

"What you see: The Total value represents a combined total of the available physical memory and virtual memory that is currently being used by the operating system and running programs. In this case, that value is 243 MB."

BTW, 其實如果你對電腦架構稍有了解的話,
也應該清楚 virtual memory 的用途,
在這種實體記憶體都只有用不到一半的情況下,
電腦根本就沒有需要去用到這麼多 virtual memory....
所以如果根據工作管理員裡面的其他數據,
稍做計算也會知道那個 PF usage 的數據,
如果只有包含 virtual memory 根本就不合理,
所以偶建議你在讀一下以下文章.

其中部分節錄.
"Most computer operating systems use the concept of virtual memory, allowing utilization of more primary storage capacity than is physically available in the system. As the primary memory fills up, the system moves the least-used chunks (pages) to secondary storage devices (to a swap file or page file), retrieving them later when they are needed. As more of these retrievals from slower secondary storage are necessary, the more the overall system performance is degraded."
