INTRODUCTIONIn todays business environment, it goes without saying that information can make or break a company. Almost any business information may be termed "strategic intelligence," depending on how it is used. Often-times, the information includes valuable data on your competitions finances, manufacturing processes, products, or advertising and promotion budgets.

Intermediate nodes are typically network hardware devices such as routers, bridges, gateways, firewalls, or switches. General-purpose computers can also forward packets and perform routing, though because they lack specialized hardware, may offer limited performance. The routing process directs forwarding on the basis of routing tables, which maintain a record of the routes to various network destinations. Most routing algorithms use only one network path at a time.

The Topology chapter presents information about the various configurations of cables. Some of the configurations are designed to minimize the inconvenience of a broken cable; with other configurations, one broken cable can stop the entire network. A great deal of attention must be paid to network services to ensure all network content is appropriate for the network community it serves.

In addition, a strategic information audit is conducted during the cor-porate awareness phase. In the star network topology, each computer is directly connected to every other computer on the network. In the bus network topology, all computers connected to a common communication medium called bus. A star topology includes a central device or hub to connect all computers together. Ring topology uses token passing and bus topology uses Ethernet. The designed suboptimal controllers are state feedback and static output feedback, which are guaranteed to provide a certain level of performance in terms of a linear quadratic regulator cost.

Enhancing Disaster Management by Taking Advantage of General Public Mobile Devices: Trends and Possible Scenarios

With the help of groupware, many users or researchers can work on their projects by sharing the same domain of information online. One copy of software can be shared over a network by multiple users. An information network is a set of two or more computers connected together to share information and resources like printer and hard disk etc. it is also called computer network.

For example, Akamai Technologies manages an overlay network that provides reliable, efficient content delivery . Academic research includes end system multicast, resilient routing and quality zona-viral of service studies, among others. An overlay network is a virtual network that is built on top of another network. Nodes in the overlay network are connected by virtual or logical links.

When one user is not sending packets, the link can be filled with packets from other users, and so the cost can be shared, with relatively little interference, provided the link isn't overused. Often the route a packet needs to take through a network is not immediately available. In that case, the packet is queued and waits until a link is free. Those corporations and organizations which develop shared information networks early in the 90s will gain a significant competitive edge in their marketplace during the next decade.

These Earth-orbiting systems are capable of receiving and relaying voice, data, and TV signals. Terrestrial microwave– Terrestrial microwave communication uses Earth-based transmitters and receivers resembling satellite dishes. Terrestrial microwaves are in the low gigahertz range, which limits all communications to line-of-sight. The following classes of wired technologies are used in computer networking. In 1976, John Murphy of Datapoint Corporation created ARCNET, a token-passing network first used to share storage devices.
