Information Technology as we know plays a very significant strategic role in the management of organizations. Information Technology is the processing and distribution of data using computer hardware and software, database management, telecommunications, and digital electronics. Information Technology makes it easy for organizations decision making because they have information at hand. In business management the term information technology is used to describe the techniques and expertise of efficient organizations, planning, direction, and control of the operations of a business. Information technology often assist managers and businesses to have more information, at their reach than ever before, modern IT improves good organization and usefulness at each stage of the strategic decision-making procedure. There is an importance of IT participation in the planning of organizational strategies.
Management staff was crucial for the successful transition to the new technology. Through the development of an intranet and database system there is now greater management control; all departments have greater access to information, which enables them to function more effectively and efficiently. Since these are so accurate and now available, they make it easy for management to make long-term strategic plans. A network flow is a sort of graph where each side has a certain capacity and each receives a flow. The amount of flow that goes through cannot exceed the maximum capacity. A flow must satisfy the restriction that the amount of flow into a node equals the amount of flow out of it. A network can be used to model traffic in a road system, fluids in pipes, and currents in an electrical circuit.
The routing of information flows with performance objectives has been an important direction in networking research. Depending on the application, performance objectives may include high through put, or quality of service objectives such as loss and delay. Network information flow is a way in which computer communicate. It is designed as a source in which computers are to multi task. It is considered to be a new form of information. The network information flow model appropriately captures the multi flow routing nature in general network topologies, as well as decodable and replicable properties of information flows. However, it assumes nodes in the network to be infinitely powerful and therefore does not accurately model queuing delay and loss at nodes.
Information in Business presents an overview of the five basic areas of information systems knowledge needed by business professionals, including the conceptual system components and major types of information systems. Organizations are becoming internetworked enterprises that use the internet, intranets, and other telecommunications networks to support e-business operations and collaboration within the enterprise, and with their customers, suppliers, and other business partners.
Telecommunications has entered a competitive environment with many vendors, carriers, and services. This type of communications technology is moving toward open, internetworked digital networks for voice, data, video, and multimedia. A major trend is the pervasive use of the internet and its technologies to build interconnected enterprises and global networks, like intranets and extranets, to
