目前使用和开发的三种远程计算（客户机/服务器）是网络计算机（Java）、Web浏览器接口和远程屏幕/键盘。远程屏幕/键盘模型提供了最大的灵活性，“最薄的客户端”：以及对用户终端升级需求的最强免疫力。它还允许使用重量轻、超便携的无线终端，同时仍然提供对最复杂的应用程序（包括因特网接入、公司信息系统和电子邮件）的访问，以及对通常可从用户的台式计算机获得的所有文件的访问。终端控制用户的虚拟个人计算机，这些计算机驻留在网络中的服务器上。作者已经构建了一个测试系统，用户满足他们的计算需求，使用终端，从一个到六磅，通过各种无线和有线方式连接。到目前为止所收集到的性能和使用统计数字，以及沿着而来的无线分组数据系统，都表明虚拟个人计算机/便携式网络模式对用户具有吸引力，而且不久将在经济上可行。
Three categories of remote computing (client/server) in use and development today are the Network Computer (Java), the Web Browser interface, and Remote Screen/Keyboard. The Remote Screen/Keyboard model offers the greatest flexibility, the 'thinnest clients': and the strongest immunity to the need for upgrades to users' terminals. It also allows the use of lightweight, ultra-portable, wireless terminals while still providing access to the most complex applications (including Internet access, corporate information systems, and E-mail), and to all the files normally available from a user's desktop computer. The terminals control users' Virtual Personal Computers, which reside on servers in the network. The authors have constructed a test system with which users satisfy their computing needs using terminals ranging from one to six pounds, connected by a variety of wireless and wireline means. Performance and usage statistics collected so far, along with coming wireless packet data systems, suggest that the Virtual Personal Computer/Portable Network model is attractive to users and will soon be economically viable.
