  Enterprise system architectures are the corner stone of major IT investments and as such have a long term impact on a corporation’s bottom line. Acceptance of the enterprise system architectures by all stake holders is vital to the successful implementation of the architecture.

This white paper also suggests some specific techniques for conducting validations of the essential aspects of enterprise system architectures. A side objective of this white paper is to stimulate discussions and sharing of real world experiences of initiating, conducting, and the overall impact of presenting the validation results.

Not only that but as consumers we should try and get as much value for our money by getting the most out of our equipment.

The shield means it can be used over long distances at high speed, but the cable is usually only used for basic installations. Another type is a twisted-pair cable, which consists of two copper strands woven into a braid and covered with insulation. It is suitable for a local network with few nodes, a limited budget and simpl...
