Question 2. 2a). The emergence of the Internet has changed the understanding of a value chain model proposed by M. Porter in 1985. In general, this model views the firm as "a series or "chain" of basic activities that add a margin of value to a firm's products or services" (Lucas, 1994)…

The Internet and digital firms have a great influence on competitive forces changing the structure of the industry within which they operate. Information technology can aid a business in using these competitive forces to its advantage. In this way information technology can be seen as a strategic competitive weapon.
2b) Computer Systems Management allows government agencies to deal with crime and terrorism effectively and give a fast respond. Electronic transmissions allow to communicate with the minimum of human intervention. The advantage is that with Electronic transmissions the information involved are exchanged electronically instead of on pieces of paper. The benefits are speed and accuracy. In addition, confidentiality can be improved because data are sent out accurately and on time. Automatic acknowledgement is made so that there should no longer be the problem of information that in the past was mislaid.
2c) By creating electronic marketplaces and linking suppliers, buyers, and sellers, the Internet and other networking technologies are improving links between them. "Electronic commerce is the process of buying and selling goods electronically by consumers and from company to company through computerized business transactions" (Lucas, 1994).

One of the inherent problems with privacy-protecting technology is that it is very difficult to know whether or not the technology is working properly, and is privacy violated or not. The gap in public trust is going to be one of the biggest problems facing the wiring up of public service delivery, and strong FOI and data protection laws are the absolute minimum requirements to bridge the divide. It is harder, and frequently more expensive, to build devices and construct services that protect people's privacy than to destroy it.
Question 3 3a) The recent software platforms development are caused by the aim to produce systems that meet user requirements. There are many systems that are technically efficient but do not serve the needs of the users and so are underused or misused. The recent development of fourth-generation languages is an alternative to the traditional linear approach to programming through specification, coding, testing and maintenance stages. Internet technology and Java software can be used to create an open system ...Download file to see next pagesRead More
