筆者之前對儲存所知甚少, 以至於看書學習起來覺得特別枯燥而且難以消化吸收(即一天以後, 看過跟沒看過一樣). 我嘗試過翻譯ISM這本書的部分章節, 效率太低, 且效果不佳. 不用說也知道, 要學什麼東西, 親自動動手是最好的方法. 但是儲存不像編程, 有一台電腦就夠了, 儲存和網路以及相關軟體可不是IT圈裡混的老百姓都能玩得起的. 後來筆者覺得, 既然這涉及到一項認證, 那麼我們用解題的方式來學習是不是會針對性強一些, 而且也不會那麼枯燥乏味. 把每一道習題涉及到的概念和解題思路都弄清楚,

文章<<The Five Minute Cheat-Sheet on SharePoint 2013′s Distributed Cache Service>>對該特性進行了很好的介紹, 推薦閱讀.這裡僅列出一些要點:1. SharePoint Distributed Cache service提供記憶體快取服務, 從而使得用戶端擷取資料的速度更快, 伴隨著它的還有SQL Server端負載的減輕.2. SharePoint Distributed

Internet Control Message Protocol (ICMP) 是Internet Protocol Suite的核心協議之一. 網路上的作業系統使用這個協議來發送錯誤資訊來說明一些東西, 比如說, 被請求的服務不可用, 或者主機或路由不能被reach到. ICMP還可以被用來轉播query messages. ICMP跟TCP和UDP這樣的傳輸協議不同, 它並不是被設計來在系統間傳輸資料的, 也不是被終端應用程式經常使用的(除了排錯工具,
