能让我们对linux的系统和socket有一个叫深入的了解，且对网络服务器的架构有一定了解，通过实践，使我们知道在网络编程过程中所需要注意的一系列问题（如并行程序设计的问题）。当然，本次大作业还能使我们对“进程间通信”，“进程同步”和“信号量”等操作系统的知识进行巩固，从而服务于本次大作业。-Make our linux system and the socket are called in-depth understanding of the network server architecture and a certain understanding, through practice, so we know network programming process in the range of Wen Ti need attention (such as parallel Cheng Xu design problem). Of course, this also gives us great job, " inter-process communication" , " the process of synchronization"　and " semaphore"　and to consolidate the knowledge of the operating system to serve this great work.
