The incoming packet's headers define which port it should be forwarded. The email traffic lands on a different port (port 25), and web traffic lands on a different (port 80) even though both reach the computer over the same network connection.

Ports facilitate computers to differentiate among different kinds of traffic.

We can recognize it as a logical construct used to specify a network service or a particular function at the software level. Each port is associated with a specific service or process. Ports are software-based and managed by the computer's operating system. It is the virtual point where the network connection starts and ends. Port is a term used in computer networking.

CSCW (computer-supported coope- tive work) in design is concerned with the development of such environments. Such environments should not only automate in- vidual tasks, in the manner of traditional computer-aided engineering tools, but also enable individual members to share information, collaborate, and coordinate their activities within the context of a design project. In order to accomplish the work, it is necessary to have effective and efficient c- laborative design environments. In addition, individual members may be working on different versions of a design or viewing the design from different perspectives, at different levels of detail. Individuals or individual groups of mult- isciplinary design teams usually work in parallel and separately with various en- neering software tools which are located at different sites. The design of complex artifacts and systems requires the cooperation of multidiscip- nary design teams using multiple commercial and proprietary engineering software tools (e.g., CAD, modeling, simulation, visualization, and optimization), engineering databases, and knowledge-based systems.
