n layer meaning in English
n 层
Examples
- Implementation of n layer system based on com
层体系结构的实现 - Then introduced the basic conception , model and their solving schemes for the electronic commerce . discussed the electronic commerce application system construction , already from traditional 2 layers develop the n layer construction
然后介绍了电子商务的基本概念、模型及解决方案。讨论了电子商务应用系统结构，已从传统的2层发展到n层结构。 - But these communication system basicly belong to global wireless communication technology , wireless communication application do n ' t restrict to these global field , however , some local region such as office , home , all kinds of information devices also require to inter - link each other by wireless instead of wire . so based on this fact , my project is put forward ; nowadays , a large number of well - rounded control software and communication software is based on rs - 232 , tcp / ip , irda and so on mature communication technology , if we do n ' t mak full use of these software and to newly develop new software based on bluetooth fully will result in wasting huge resource existed . ; com technology have stronger reuse , independen location , and inter - flatform and so on peculiarity , and the n layer structure of dcom server can independedly encapsulate and run bluetooth logical process , moreover , dcom will provide bluetooth services to high layer but maskingthe bottom bluetooth communication process ; as a new communication technology , the protocol model and realization of bluetooth technology both in a low development stage , so this paper make amount of work about it to deeply analyse bluetooth core protocol
但这些通信系统基本上属于广域的无线通信技术，而无线通信的应用并不局限于广域的移动通信，在办公室，家庭短距离内，各种信息设备间也要求能以无线方式互联，替代现有的有线连接方式，这就是本课题提出的来由；现有的大量的已开发(成熟)的控制软件和通信软件是基于成熟的rs - 232 ， tcp ip ， irda等通信技术的，如果不加以利用而重新开发基于蓝牙协议之上，将是一笔巨大的浪费；使用com技术编写的组件具有重用性强，位置透明，可以跨平台等优点，而dcom服务器的n层式结构可以独立封装并运行蓝牙逻辑过程，相对于上层屏蔽了其蓝牙底层通信细节而向上层提供蓝牙服务；蓝牙技术作为一种新兴通信技术，其协议模型和实现细节以及互操作性应用都处于研究发展初级阶段，本文通过深入剖析蓝牙核心协议，提出了基于dcom技术和sdl描述来构建一个新型的，支持多个例程的，多语言开发的，封装蓝牙协议通信细节的蓝牙协议栈dcom服务器。
