Description: The tracert tool displays the various IP Addresses in the route of a network packet as it travels to a destination IP address from a source. An article which describes how tracert works and which also presents a C# component to implement tracert functionality in your projects can be found here. In the tool presented in this article, I combine the tracert component, technology to geo-locate based on IP address from HostIP.info and the Virtual Earth API to map the locations of various IP addresses that fall in the route of a network packet when it travels to a user provided destination IP address. Since the tracert component is covered thoroughly in the other article let start by looking at geo-location and the MSN Virtual Earth API.-The tracert tool displays the various IP Ad dresses in the route of a network packet as it tra vels to a destination IP address from a source.

Description: 利用虚函数手段，按照三种不同的数据存储方式及其处理方法来实现如下的所谓“反序输出问题”：从键盘输入n 个int 型数据先存储起来（具体n 值由用户从键盘输入），而后再按照与输入相反的顺序将这些数据显示在屏幕上。具体地说，可通过在基类baseCla 及其派生类method1Cla、method2Cla 和method3Cla中说明如下的同一个虚函数“virtual void reverseout() ”，来实现所述问题的三种不同处理方法。例如，可设计并使用已经在第四章和第六章的实践题中所使用的数据存储结构以及处理方法：（1）使用大小为100 的常界数组存放数据；（2）通过new 生成大小恰为n 的动态数组存放数据；（3）使用指针与链表的实现法。

Description: Trie树既可用于一般的字典搜索，也可用于索引查找。对于给定的一个字符串a1,a2,a3,...,an.则采用TRIE树搜索经过n次搜索即可完成一次查找。不过好像还是没有B树的搜索效率高，B树搜索算法复杂度为logt(n+1/2).当t趋向大，搜索效率变得高效。怪不得DB2的访问内存设置为虚拟内存的一个PAGE大小，而且帧切换频率降低，无需经常的PAGE切换。-Trie tree can be used for general dictionary english, can also be used to search the index. For a given a string a1, a2, a3 ,..., an. Is used TRIE tree english english after n times to complete a search. But they did not like B-tree search efficiency, B tree search algorithm complexity is logt (n+ 1/2). When t trend, and search efficiency becomes efficient. No wonder the DB2 access memory settings for the virtual memory size of a PAGE, and the frame switching frequency to reduce the need for frequent switching PAGE.

系统，当然，这个设置是可以修改的(修改文件/etc/inittab)。每一个虚拟控制台允许让一个用户登录，我们可以使用
ALT+Fn(n=1,2,3,4,5,6)来登录或者是切换到某个虚拟控制台，它们分别对应tty1到tty6虚拟终端。-linux by default, Linux can use 6 virtual consoles to log in local Linux (local terminal) system, of course, this setting can be amended (to modify the file/etc/inittab). Each virtual console to allow a user log, we can use ALT+ Fn (n = 1,2,3,4,5,6) to log in or switch to a virtual console, tty1 they correspond to tty6 virtual terminal.
