Description: 介绍在多道程序系统中，一个作业从提交到执行，通常都要经历多级调度，如高级调度、低级调度、中级调度以及I/O调度等。而系统的运行性能，如吞吐量的大小、周转时间的长短、响应的及时性等，在很大程度上都取决于调度，因而调度便成了多道系统的关键。-introduced in the multi-program systems, operating from a submission to the Executive, normally you have to go through multi-level scheduling, such as higher scheduling, dispatching junior, intermediate Scheduling and I / O scheduling. While the operating system capabilities, such as throughput size, the length of turnaround time, the timeliness of response, will depend largely on scheduling, which has become more scheduling system to the key.

Description: 原理图常见错误： （1）ERC报告管脚没有接入信号： a. 创建封装时给管脚定义了I/O属性； b.创建元件或放置元件时修改了不一致的grid属性，管脚与线没有连上； c. 创建元件时pin方向反向，必须非pin name端连线。 （2）元件跑到图纸界外：没有在元件库图表纸中心创建元件。 （3）创建的工程文件网络表只能部分调入pcb：生成netlist时没有选择为global。 （4）当使用自己创建的多部分组成的元件时，千万不要使用annotate.-principle of common mistakes : (1) ERC report no access to signal pins : a. creation package to the pin at the definition of I / O attribute; b. create components or modify components placed inconsistent grid attributes, and the lines do not pin connection; c. create components reverse direction when the pin, non-name-pin connections. (2) components went to the drawings profession : no paper charts component library center components. (3) the creation of the document network table works only partially transferred PCB : netlist generation did not choose to global. (4) When the use of their own creation, multi-component element, we must use annotate.

Description: 端口扫描
扫描器的一个主要功能就是发现一个主机或网络并检查有什么服务正运行在这台主机上，更进一步还能测试这些服务，发现系统漏洞。要实现这些功能，只需要采用罪简单TCP connect（）扫描。操作系统提供的connect（）系统调用，用来与每一个目标计算机端口进行连接。如果端口处于侦听状态，那么connect（）就能够成功；否则这个端口不能使用，即没有提供服务。这个技术的最大有点是：无需任何权限。系统中的任何用户都有权利使用这个调用。另一个好处是速度，如果对每个目标端口以线性的方式，使用单独的connect（）调用，那将会花费相当长的时间。我们可以同时打开多个socket，从而加速扫描。使用非阻塞I/O允许设置一个较低的时间用尽周期，同时观察多个socket。但这种方法的缺点是很容易被发觉，并且被过滤掉。目标计算机的logs文件会显示一连串的连接和连接是出错的服务消息，并且能很快的使它关闭-port scanner scans one of the main functions is found a host or network and check what services are running in this host, but also further test these services, discovered vulnerabilities. To achieve these functions, the offense only needed a simple TCP
