The Rational Unified Process (RUP) is a software engineering process, which captures many of best practices in modern software development. The notions of 3 and scenarios have been proven to be an excellent way to capture function requirements. RUP can be described in two dimensions - time and content. In the time dimension, the software lifecycle is broken into cycles. Each cycle is divided into four consecutive 4 which is concluded with a well-defined 5 and can be further broken down into 6 - a complete development loop resulting in a release of an executable product, a subset of the final product under development, which grows incrementally to become the final system. The content structure refers to the disciplines, which group 7 logically by nature. 用户可以通过http://www.a.corn和http://www.b.com访问在同一台服务器上______不同的两个Web站点。
A. IP地址
B. 端口号
C. 协议
D. 虚拟目录
