What is an information system?

What is role of management information system?3 mks An information system can be any organized combination of people , hardware, software, communication network and data resources that stores and retrieves , transforms, and disseminate information in an organization. Information system is a set of people, procedures and resources that collects , transforms, disseminates information in an organisation. People have relied on information system to communicate with each other using variety of physical devices (hardware) , information processing, instruction and procedures(software), communication channel (network)and stores data since the dawn of civilization.2)Draw a neat sketch of hardware component of a computer system storage unitSecondary storagePrimary storageControl unitArithmetic unitInput unitOutput unitinfo3)What is database ? a data base is an integrated collection of logically related records & filesIt consolidates records previously stored in independent files so that it serves as a common pool of data to be accused by many different application programs.The data stored in database is independent of the computer programs using it and of one type of secondary storage devices on which it is stored.4)What is CRM ? Customer relationship management is a comprehensive set of process and technologies for managing the relationship with potential and current customer across the business function.Goal : to understand and anticipate the needs of current and potential customers to increase retentions and loyalty while optimizing the way that products and services are soldWhat are the roles of management information system ?It plays an identical role ensuring that an appropriate data is collected from various sources ,processed and sent to the needy destination; fulfills the information needs of the individual ,group and management functionaries It satisfies the deserves needs through a variety of systemsIt helps all the management levels in an organization such as strategic planning, tactical planning .List the difference between system software and application software ?3mksSystem softwareIt offers convenience too application programmers and computer users.Allows application software to be run on the computer with less effort.It is generally provided by the system .Application softwareIt requires the help of the software to interface for its execution.In application software, the effort related on their execution is dependantApplication software are purchased or developed by the organisation.Distinguish between LAN and WAN ?3mksBASISLOCAL AREA NETWORKWIDE AREA NETWORKGEOGRAPHICAL DISTANCEDiameter of not more than a few kilometers.Span entire countriesspeedA total data rate of at least several MbpsData rate less than 1 MbpsownershipCompanies ownership by a single organizationOwned by mutliple organisation.Frequency of errorsVery low error rates comparatively higher error rates.topologySymmetrical topology , ring, bus.Several topologies star, ring , mesh.What is data warehouse ?3mksA data ware house is a repository of information gathered from wide multiple sources, stored under a unified scheme at a single site . This data is stored generally for a long time permitting access to historical data .in this way, data warehouse are useful by providing the user a single consolidated interface to data, making decision support queries easier to attendWhat is SCM ?3mksSCM is a cross functional inter enter price system that uses information technology to help support and manage the links between some of a companys key business process and those of its suppliers , customers and business partners . The goal of scm is to create a fast , efficient and low cost network of business relationships or supply chain to get a companys products from concept to market .What do you understand by the term hacking?3mksHacking always involves some degree of infringement on the privacy of others or damage to computer based property such as files, web pages or softwareIt is the practice of modifying computer hardware and software to accomplish a goal outside of the creators original purposePeople engaged in computer hacking activities are called hackersWhat is system analysis and design ? 3 mksSystem analysisSystem analysis is a systematic investigation of a real or plant system to determine the functions of the system and how they relate to each other and to any other system .System design System design is the process of defining the architecture, components , modules , interface and data for a system to satisfy specific reqiurements. System design involves the analysis,design and configuration of the necessary hardware and software to support solution architecture . 5 major components of system design include 1)the information model 2) community model3) security model 4) system integration 5) technical architectureWhat is CRM?3mks It is a comprehensive set of processes and technologies for managing relationship with potential and current customers across the business functions.7 marks question2(b).

Topology is a layout showing how the connectivity communicate and information flows takes place in network.

Bus Topology

In this topology the terminals are connected through one cable and the circuit cable is called bus.Terminals decides the ownership of the message and act.If the message does not belong to the terminal it ignores.The message can travel in both directions.If one of the terminal fails, none of the other components in the network are affected.Network can handle only one message at a time.

Star Topology

In this topology, the communications are routed by the central system known as the server.The communications is through the server.The traffic on network cable is very high.The server is a network traffic controller.If the server fails, the entire network is down.

Ring TopologyThe terminals are connected on the ring like cable layout.The communication takes place from 1st terminal to 2nd to 3rd and so on.The network fails if any one computer fails to perform.The communication moves with the address and at each station, the address is determined is valid or not.If the address is valid, the communication is accepted, otherwise it is passed on to the next PC.In this there is no host computer or server.Each computer in the network can communicate directly with any other computer.

R.INFORMATION SYSTEM Manufacturing information system MARKETING INFORMATION SYSTEMPERSONNEL INFORMATION SYSTEM1.Financial Information System

It provides financial information not only for executives but also for a broader set of people who need to make better decision on a daily basis.It provides information to persons and groups both inside and outside the firm concerning the firms financial matters.2.Acconting information systemThe AIS performs the firms accounting applications. A high volume of data processing characterises these appplications.It processes a mixture of quantitative and qualitative data.but it focuses almost entirely on processing quuantitative data.3.H.R. Information systemThey are the information system that supports human resource management activities . The business function emphasises on - planning to meet the personnel needs of business - development of employees to their full potential - control of all personnel policies and programs.

4.Manufacturing information system It is a complete set of tools for managing the flow of manufacturing production data throughout the enterprise.It is designed to provide tools for both IT and operations personnel who would deliver services to anyone in the plant5.Marketing manufacturing systemAmarketing information systemis amanagement information systemdesigned to support marketing decision making.Jobber (2007) defines it as a "system in which marketing data is formally gathered, stored, analysed and distributed tomanagersin accordance with their informational needs on a regular basis."Kotler, et al. (2006) define it more broadly as "people, equipment, and procedures to gather, sort, analyze, evaluate, and distribute needed, timely, and accurate information to marketing decision makers.
