In a global marketplace, information has emerged as an agent and enabler of new competitiveness for today’s enterprise. However the paradigm of strategic planning changes sufficiently to support the new role of information and technology. The question is, are changes can support the new role of information and technology and what is the relationship between strategic information system planning with the development database in an organization. Therefore, the development of strategic information system planning is importance in an organization. Strategic information systems planning (SISP) is the process of creating a portfolio based on the use of information system in order to achieve organizational goals and objectives. Within SISP, organizational can clearly define their organizational goals, the critical success factor (CSF) and the problem areas within the organization activity. Introduction to Strategic Information Systems Planning (SISP) There are two concepts of strategic information systems planning (SISP). The first one is SISP Continue reading

What is Web Mining?
Web Mining is the technique which is used to extract and discover the information from web documents and services automatically. The interest of various research communities, tremendous growth of information resources on Web and recent interest in e-commerce has made this area of research very huge. Web mining can be usually decomposed into subtasks. Resource finding: fetching intended web documents. Information selection and pre-processing: selecting and preprocessing specific information from fetched web resources automatically. Generalization: automatically discovers general patterns at individual and across multiple website Analysis: validation and explanation of mined patterns. Web Mining can be mainly categorized into three areas of interest based on which part of Web needs to be mined: Web Content Mining, Web Structure Mining and Web Usage Mining. Web Contents Mining describes the discovery of useful information from the web contents, data and documents. In past the internet consisted of only different types of services Continue reading
Voice Over Internet Protocol (VoIP)
Voice over Internet Protocol or Voice over IP or VoIP is a general term for a family of transmission technologies for delivery of voice communications over internet protocol networks such as the internet or other packet-switched networks. Other terms frequently encountered and synonymous with voice over internet protocol are internet protocol telephony, internet telephony, voice over broadband, broadband telephony, and broadband phone. Internet telephony refers to communications services – voice, facsimile, and/or voice-messaging applications – that are transported via the internet, rather than the public switched telephone network. Definition of Voice Over Internet Protocol (VoIP) Voice over internet protocol can be defined as the ability to make telephone calls and to send facsimiles over internet protocol- based data networks with a suitable quality of service and a much superior cost/benefit. Equipment producers see Voice over Internet Protocol (VoIP) as a new opportunity to innovate and compete. The challenge for then Continue reading
Architecture and Key Characteristics of Cloud Computing
Cloud Computing Architecture Cloud computing architecture, the systems architecture of the software systems involved in the delivery of cloud computing, typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services and 3-tier architecture. This resembles the Unix philosophy of having multiple programs each doing one thing well and working together over universal interfaces. Complexity is controlled and the resulting systems are more manageable than their monolithic counterparts. The two most significant components of cloud computing architecture are known as the front end and the back end. The front end is the part seen by the client, i.e. the computer user. This includes the client’s network (or computer) and the applications used to access the cloud via a user interface such as a web browser. The back end of the cloud computing architecture is the ‘cloud’ itself, comprising various computers, servers and data storage devices. Continue reading
Data Transmission Modes in Computer Networks
Data communication circuits can be configured in a huge number of arrangements depending on the specifics of the circuit, such as how many stations are on the circuit, type of transmission facility, distance between the stations, how many users at each station and so on. Data communication circuits can however be classified as either two point or multipoint. A two-point configuration involves only two stations, whereas a multipoint configuration involves more than two stations. Regardless of configuration, each station can have one or more computers, computer terminals or workstations. A two point circuit involves the transfer of digital information from a mainframe computer and a personal computer, two mainframe computers, two personal computers or two data communication networks. A multipoint network is generally used to interconnect a single mainframe computer to many personal computers or to interconnect many personal computers. Coming to transmission modes, there are three modes of transmission Continue reading
E-Business Model – Meaning, Elements and Types
In this Globalization era the developed, undeveloped and developing countries are preparing their societies and communities for globalization. The globalization is possible only because of revolution in communication technology. The concept of global economy is emerging which is making e-business, an indivisible component of business strategy planning. Banking, tourism, shopping, hotel booking, airlines booking, auctioning and the list is non-ending. Millions of internet users just rely for their financial as well as other services on their online transactions. As more and more people have started using internet, more specifically e-business, for their day to day working, e-business has become more and more popular. The excitement of using e-services has grown and the potential for success of businesses increased. As more and more companies have started using internet for their business growth, some problems have to be understood properly and the solutions to them have to be thought carefully. At one Continue reading
