BUILDING A SHARED INFORMATION NETWORK

Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and video game consoles. A wired PAN is usually constructed with USB and FireWire connections while technologies such as Bluetooth and infrared communication typically form a wireless PAN. Routing can be contrasted with bridging in its assumption that network addresses are structured and that similar addresses imply proximity within the network. Structured addresses allow a single routing table entry to represent the route to a group of devices. In large networks, the structured addressing used by routers outperforms unstructured addressing used by bridging. Unstructured MAC addresses are used for bridging on Ethernet and similar local area networks.

National Information Network

This hoarding of intelligence puts companies at a competitive disadvan-tage. Companies that can quickly retrieve internal information and efficiently synthesize and disseminate external information have an advantage over those organizations that cannot. Further-more, each manager or executive is a data base of information, with years of functional and indutry expertise making him zona-viral a resident expert on certain topics. Getting access to your co-workers or subordinates areas of expertise requires that you tap into their data bank of information, which is stored in their brain. Thus, the infloglut factor has led to the increased emphasis on and impor-tance of information sharing within organizations. The application layer is the top-most layer of OSI model.

The client computer requests a service from the server computer. The server computer provides the requested service to the client computer. In client/server model, a computer connected in the network is called client. The client computer sends requests to the server computers. Workgroup computing is highly important aspect of modern world computing in today’s business, academic, technological and research oriented atmosphere. It is also known as collaborative computing and it enables the individuals and teams of certain projects to use computer networks for the purpose of cooperation, consultation, and information sharing.

Intranets do not have to be connected to the Internet, but generally have a limited connection. An extranet is an extension of an intranet that allows secure communications to users outside of the intranet (e.g. business partners, customers). The introduction and rapid growth of e-commerce on the World Wide Web in the mid-1990s made it obvious that some form of authentication and encryption was needed. At the time, the dominant web browser was Netscape Navigator. Netscape created a standard called secure socket layer . When a client requests access to an SSL-secured server, the server sends a copy of the certificate to the client.

Users are assigned an ID and password that allows them access to information and programs within their authority. Network security is used on a variety of computer networks, both public and private, to secure daily transactions and communications among businesses, government agencies, and individuals. Storage area networkA storage area network is a dedicated network that provides access to consolidated, block-level data storage. SANs are primarily used to make storage devices, such as disk arrays, tape libraries, and optical jukeboxes, accessible to servers so that the storage appears as locally attached devices to the operating system. A SAN typically has its own network of storage devices that are generally not accessible through the local area network by other devices.

What is Information Network/ Computer Network?

In 1973, the French CYCLADES network was the first to make the hosts responsible for the reliable delivery of data, rather than this being a centralized service of the network itself. There should be a thorough semiannual review of a network, rather than a quarterly review, to allow a time frame long enough to pinpoint tangible benefits or savings. Typically, such a review entails the use of hard copy questionnaires or personal interviews. Having personally executed them, I can honestly say that this is not an easy task.

Information Networks or Computer Networks

With fiber optics, repeaters can be tens or even hundreds of kilometers apart. Network connections can be established wirelessly using radio or other electromagnetic means of communication. In 1995, the transmission speed capacity for Ethernet increased from 10 Mbit/s to 100 Mbit/s. By 1998, Ethernet supported transmission speeds of 1 Gbit/s.

Such modifications may include allowing for refinements of the actual format and data base design. For instance, many executives prefer infor-mation that is summarized by key points, rather than in general prose or paragraph form. The prototype for a business intelligence network acts as a small-scale offering or test market of the network. At this point, the internal champion and the task force must decide whether to develop the prototype in-house or hire on outside firm.
