Defining features of a CHIN are that its services are available to all stakeholders

Information network or social network? Proceedings of the 23rd International Conference on World Wide Web

Defining features of a CHIN are that its services are available to all stakeholders and that competitors collaborate to share information. The initial impetus for a CHIN is usually to facilitate paying for health care or to share clinical records. Complex legal, organizational, funding, and control issues confront CHIN initiators, and reliable models do not exist today. During development, issues of program focus and technology selection arise, followed by concerns about information privacy and the CHIN's role in quality of care.

A rigorous screening procedure was implemented to determine which documents should be abstracted for the system (refer to "The Intelligent Corpo-ration," Ruth Stanat, Amacom Spring 1990). Additionally, the data format included a section for "key findings" which enabled the user of the database to determine the relevance or value of the document for future referral . During this phase, the company outlines the information architecture or the actual blueprint of the intelligence network.

These centers are legally independent and have chosen to cooperate to improve the quality of care. The New York State network is one of the best known and it includes almost all State hospitals, thousands of professionals and 40 million people living in New York State. They allow the sharing of information between these different structures and their healthcare professionals for the care of the same patients. An intranet is a set of networks that are under the control of a single administrative entity. The intranet uses the IP protocol and IP-based tools such as web browsers and file transfer applications.

End users also should be involved in the design and development of the prototype. Just as a manager or administrator would set up his or her own filing system to be able to find specific in-formation, the users of the system should have input into the content and format of the data base. The following four phases are involved in developing an intelligence network. They can serve as a benchmark for organizations implementing a network and are especially useful for those "stuck" at a certain phase.

Chapter 1: What is a Network?

These systems can only guarantee the protection of communications between clients and servers, not between the communicating parties themselves. Examples of non-E2EE systems are Google Talk, Yahoo Messenger, Facebook, and Dropbox. Some such systems, for example, LavaBit and SecretInk, have even described themselves as offering "end-to-end" encryption when they do not. Some systems that normally offer end-to-end encryption have turned out to contain a back door that subverts negotiation of the encryption key between the communicating parties, for example Skype or Hushmail.

A communication protocol is a set of rules for exchanging information over a network. They may be connection-oriented or connectionless, they may use circuit mode or packet switching, and they may use hierarchical addressing or flat addressing. Message flows between two devices (A-B) at the four layers of the TCP/IP model in the presence of a router .

The work group members may be at different places in the world. They can share their ideas and experiences using computer network. Different types of files, pictures, sounds, videos and graphics can be exchanged among the member of work-group. Networks are used to share different devices such as printers and hard disks etc. To detect and protect the HIS against spoofing attacks, server sides must frequently change the authentication credentials and enable duplicate detection techniques. DVB have also suggested optional tables specifying groups of services (‘bouquets’), which present viewing options to the viewer in a more amenable (tempting!) way.

Ring topology is difficult to troubleshoot but bus topology is easy to troubleshoot. In this topology, each computer is connected to the next computers with the last one connected to the first. In this network topology, all computers are connected to a common communication medium called bus. The files and peripheral devices are zona-viral distributed across several computers on the other computer that have access to it over the network. A computer network is a set of two or more computers connected together in order to share information and other resources. The computer in a network is connected with one anther through cables, satellite or telephone lines.
