Routing of routing is performed based entirely on the destination address of the message. An address has the following format: domain. The local mail server then performs a DNS lookup to find the 'MX' (mail exchanger) records for the recipient's domain name. These MX devices are the designated mail servers for all addresses within that domain.

Collaborative Computing Collaborative computing is a term describing a variety of activities where people interact with one another using desktops, laptops, palmtops, and sophisticated digital cellular phones. As computers are best at handling data and representing information, person-to-person communication is enriched by an ability to share, modify, or collaboratively create data and information.

Grid Computing Grid computing has emerged as one of the key computing pattern enabling large-scale and enhanced scientific activities to be carried out via collaborations on a global scale. Grid Computing enables the virtualization of distributed computing, data resources and the network bandwidth to create a single system image. Grid computing is based on an open set of standards and protocols that enable communication across heterogeneous, geographically dispersed environments. They are often connected to each other through fast LAN
