A processor refers to unit which processes the input received the way it has been instructed. In a computer the processor is the CPU – Central Processing Unit. It does all mathematical calculations, logical tasks, storing details in the memory etc. Output unit is used to give output s from the computer. Examples of output unit – Monitor, printer, speakers etc.
Organization of Business in an E enterprise – Software Applications in MIS
Internet technology is creating a universal bench or platform for buying and selling of goods, commodities and services. Essentially Internet and networks enable integration of information, facilitate communication, and provide access to everybody from anywhere. And software solutions make them faster and self-reliant as they can analyze data information, interpret and use rules and guidelines for decision-making. These enabling capabilities of technology have given rise to four business models that together work in an E enterprise organization. They are:
• E business
• E communication
• E commerce
• E collaboration
These models work successfully because Internet technology provides the infrastructure for running the entire business process of any length. It also provides email and other communication capabilities to plan, track, monitor and control the business operations through the workers located anywhere. It is capable of linking to disparate systems such as logistics, data acquisition and radio frequency used systems and so on. Low cost connectivity physical, virtual and universal standards of Internet technology make it a driving force to change conventional business model to E business enterprise model.
Internet has enabled organizations to change their business process and practices. It has dramatically reduced cost of data and information processing, its sending and storing. Information and information products are available in electronic media, and is a resident on the...

...Q1. Explain DFD & Data Dictionary? Explain in detail how the information requirement is determined for an organization?
Ans: Data Flow Diagrams(DFD):
Data flow diagrams represent the logical flow of data within the system. DFD uses few symbols like circles and rectangles connected by arrows to represent data flows. DFD can easily illustrate relationships among data, flows, and external entities stores. DFD can also be drawn in increasing levels of detail, starting with a summary high level view and proceeding to more detailed lower level views..
The open-ended boxes represent data stores, sometimes called files or databases. These data stores correspond to all instances of a single entity in a data model. Arrow represents data flows, inputs and outputs to end from the processes. A number of guideline should be used in DFD
Choose meaningful names for the symbols on the diagram.
Number the processes consistently. The numbers do not imply the sequence.
Avoid over complex DFD.
Make sure the diagrams are balanced Data Dictionary
The data dictionary is used to create and store definitions of data, location, format for storage and other characteristics. The data dictionary can be used to retrieve the definition of data that has already been used in an application. The difficulty to determine a correct and complete set of information is on account of the factors given below:
The capability constraint of the human being as an information processor, a problem...
