... advantages RAD tools promise over traditional programming are shorter, more flexible development cycle and the fact that applications can be developed by a reasonably sophisticated end user. The main disadvantage is that RAD tools often require code to be written, which will result in most developers probably having to learn to program using the underlying programming language, except in the case of the simplest applications. The time gained from using a RAD tool can be immense, however: Programmers using IBM's VisualAge report the ability to create up to 80 percent of an application visually, with the last 20 percent consisting of specialized functions, which ...

... not visit the business, it means having a prominent high street location is no longer of importance; in fact a business can be set up in someone’s home (if space for storage allows!). Also when considering mail order companies there is no longer the need to endure the costs of designing, printing and sending out catalogues. These factors contribute to e-commerce companies being able to offer products at greatly reduced prices as overheads have been minimised. A company now has the ability to provide customers with a catalogue that has a far more extensive range than that of which any mail-order catalogue could provide. Recently Amazon have advertised that they ...

(The term hardware describes the physical aspects of computers and related devices.) can be thought of as the variable part of a computer and hardware the invariable part. is often divided into application (programs that do work users are directly interested in) and system (which includes operating systems and any program that supports application ). The term middleware is sometimes used to describe programming that mediates between application and system or between two different kinds of ...

... out of sheer laziness. They used the two-digit system to cut down on the number of keystrokes needed to complete the programming, which helped them complete their task faster. It was discovered in the late 1980’s that this Y2K bug could cause computer systems to fail when the year 2000 rolled around because computers might fail to recognize that it is the year 2000 versus 1900. The problem is going to affect the whole world. How does affect the average person? It is possible that the electric companyies’ computers could crash, which could cause either blackouts or brownouts. It would mean no heat for your house and no way to store perishable items. It would ...

... explorer, you click on the icon answer the wizard's questions and the computer performs the work. Making sure everything is setup properly without the errors that could occur in configuring the task yourself. The wizard performs all the functions on its little to-do list without having the user worrying about whether he/she remembered to include all the commands. On the side of personal views the user may see the wizard as a new task to learn but in general it is simpler than having to configure the application yourself and making an error, that could cause disaster to your system. The wizard also prevents the user from having to deal with all the internal ...

... a computer to understand written or spoken information and to produce summaries, answer specific questions, or redistribute information to users interested in specific areas of this information. Essential to such programs is the ability of the system to generate grammatically correct sentences and to establish linkages between words, ideas, and associations with other ideas. Research has shown that whereas the logic of language structure—its syntax—submits to programming, the problem of meaning, or semantics, lies far deeper, in the direction of true AI. In medicine, programs have been developed that analyze the disease symptoms, medical history, and laboratory tes ...

... part of the human race. According to the Americans with Disabilities Acts, any office that has a staff of more than fifteen people now has to provide adaptive hardware and software on their computers, so that workers with disabilities can accomplish many tasks independently. Before this Act was passed the disabled were normally passed over for jobs because of their handicap, now however employers can be assured that people with disabilities can work in the work place just like people without disabilities. The self esteem disabled individuals have gained from the experience to work and be self supporting, is immeasurable. Computerized wheelchairs have given ...

Other "small time" hackers affect people just as much by stealing or giving away copyrighted software, which causes the prices of software to increase, thus increasing the price the public must pay for the programs. Companies reason that if they have a program that can be copied onto a disc then they will lose a certain amount of their profit. People will copy it and give to friends or pass it around on the Internet. To compensate, they will raise the price of disc programs. CD Rom programs cost more to make but are abo ...

... would also be true. A laser is useful because it produces light that is not only of essentially a single frequency but also coherent, with the light waves all moving along in unison. Lasers consist of several components. A few of the many things that the so-called active medium might consist of are, atoms of a gas, molecules in a liquid, and ions in a crystal. Another component consists of some method of introducing energy into the active medium, such as a flash lamp for example. Another component is the pair of mirrors on either side of the active medium which consists of one that transmits some of the radiation that hits it. If the active component in ...

... theoretical causes for technology advancement and the second point being, conceptual ideas currently in the works. In our research, we found that concrete findings were rare and few between, being that much of this subject is speculation or “napkin” design ideas. However; with all that our society is accomplishing and inventing everyday, it is easy to visualize the possibilities that we may be looking forward to in the coming years. Causes: Some theoretical explanations There is no exact, scientific reason for which manufactures are looking to the future of construction machinery and seeing the equipment being run by computers, not operators. But there are ...
