In the previous unit, we have discussed the concept of E-Commerce, which includes the role of ICT in the area of commerce. Now let us see the role of ICT in the public administration area. Global shifts towards increased deployment of IT by governments emerged in the nineties, with the advent of the World Wide Web. What this powerful means to publish multimedia, support hyperlinked information and interactive information meant was a clearer avenue for G to C interactions and the promise of the attainment of the goals of good governance. Governments weighed down by the rising expectations and demands of a highly aware citizenry suddenly began to believe that there can be a new definition of public governance characterized by enhanced efficiency, transparency, accountability and a citizen-orientation in the adoption of IT enabled governance. Here we will discuss the concepts of E-Governance. Governance is a burning topic for many reasons, including the changing role of knowledge and info...

 Commerce has a long tradition of profiting from innovative systems and tools. As technologies emerge, successful businesses are quick to identify developing opportunities and expand their commercial capabilities. Conducting commerce electronically is no different. For many businesses, new technologies that digitally exchange text and monetary information are effective tools to serve traditional business goals of streamlining services, developing new markets, and creating innovative business opportunities. In addition, they offer the potential to develop types of services that are so innovative and distinct from tradition that they define a new type of commerce. Appropriately named, electronic commerce (E-Commerce) is the synthesis of traditional business practices with computer, information and communication technologies. http://store.templatemonster.com/?aff=orlandoweb E-Commerce is not an entirely new type of commerce. It first emerged in the 1960's on private networks, as typic...

Cyberspace is such a term, which is not yet completely defined and also has no geographical limitation. It is a term associated with application of the Internet worldwide. It is also called as a virtual space as physical existence of cyberspace is not detectable at all. Cyberspace is “the total interconnectedness of human beings through computers and telecommunication without regard to physical geography.  Cyberspace is a term coined by science fiction author William Gibson to describe the whole range of information resources available through computer networks. For our purposes, cyberspace is a realm in which communication and interaction between two individuals or between an individual and a computer is facilitated by digital data exchanged over computer networks. This interaction or communication can be used for a host of different purposes. The Internet is currently the biggest network for linking computers, but cyberspace, as a concept, is independent of the Internet. Cyberspa...

 ICT deals with how digital information passes between the devices. The most prolific example is the Internet, a worldwide network of computers linked together by telephone lines. There are however, other examples, like mobile phones, interactive televisions and personal organizers. When ICT is applied to business, it can lower Costs, raise productivity and improve customer and supplier relationship. In learning, ICT widens participation and raises attainment. In public services, ICT engages people with services more effectively and in communities, ICT links people to economic opportunity and brings together those with common agendas. The opportunities for social and economic development which can not be availed by the people because of inaccessibility and lack of information will now be available to all. This information could be used for trade, online education, telemedicine, egovernment and many other applications that solve vital problems in the developing countries. It could o...

 Information technology [IT] and computers have enormous influence on all segments of our life. All our workplaces and the living surroundings are being mechanized or rather automated. The benefit of information technology is that, it empowers people to do what they want to do, let’s people to be creative, make people to be productive and allow people to learn things which they didn't think they could learn before, and so in a sense it is all about potential. Technology, in all its forms, has had an impact on practically one and all. Information technology, with its complication and remarkable alteration, has debatably had the most philosophical force on community. Information is any type of pattern that influences the formation or transformation of other patterns. Information technology makes it practicable for all sorts of information to be stored, accessed and transmitted electronically, and with no orientation to customary print on paper media. Here we will explore IT and its a...

The previous two articles discussed about the fundamentals of information as well as network security issues which lead to different kinds of problem: attacks, theft of essential information and software vulnerabilities. Here we shall learn about how to build a secure network. We shall also learn about the various parameters which must be considered for network security. There can be various security issues involved in small and medium sized businesses which require utmost attention for creating the secure network. Then we shall be covering different kind of tools available for network security, critical elements of network security like Firewall, password mechanisms, encryption, authentication & integrity etc. Lastly, we shall study about some secure network devices like secure modems. Let’s first read the basics of network and network security. As we know the basics of network and its security. Computer network is defined as system of interconnected computers linked by communicat...

Software vulnerability is defined as we have studied previously. Virus is a common term understood as software vulnerability by average people. It is a problem that is potentially so dangerous that it threatens the proper functioning of the computer system in today's information age. In this unit you will learn about the unwanted software that is deliberately bad in intent which is “wrote for fun” or “for curiosity” or simply to challenge to create the most destructive software ever built. This software is popularly known as “malware” which is an acronym for malicious software. Malware does nothing useful but rather more harmful. Here we will study several types of malware each of which has different goals and propagates differently. Here we discussed about the threat faced by computer virus. It explains the evolution characteristics of the virus and the damage they can do to a computer. We studied different types of viruses and their characteristics. It also discussed about differ...
