... This approach had one major flaw: because of its strict sequence, nothing of substance could be demonstrated to the end user until the final stage of the waterfall cycle was completed. During the 1970’s, a new approach was developed. Tom Demarco, is his book, Structured Analysis and System Specification, introduced model-based software engineering. Demarco thought that complex software systems should be built like any large, complex engineering system, by first building working paper models of the system before committing the resources for implementation. This allowed the user to visualize the future system. Most modern approaches have integrated some fo ...

... be used for more practical purposes. These purposes include national defense, surgical procedures and various other applications. Society has not fully acknowledged the benefits of virtual reality as of yet because it is still under development. The reason for virtual reality remaining in its development for so long is mainly due to its complexity. The hardware that has developed so far is unable to make the large calculations required by a virtual reality based machine. However, as apparent in recent years, technology is advancing at an extreme rate. This is another reason why society's hopes for virtual reality should and have remained unwaivered. In Oren ...

Software is any of the programs used in operating a digital computer, as input and output programs, as defined by Funk and Wagnalls Standard Desk Dictionary. When we purchase computer software, we purchase it with the understanding that it will be for use on a single computer, once installed on that system, it is not to be loaded on any other computer.

... or powering up the computer. You can bypass the extended CMOS settings by holding the key down during boot-up. This is really helpful, especially if you bend the CMOS settings right out of shape and the computer won't boot properly anymore. This is also a handy tip for people who play with the older AMI BIOSes with the XCMOS setup. It allows changes directly to the chip registers with very little technical explanation. A Typical BIOS POST Sequence Most BIOS POST sequences occur along four stages: 1. Display some basic information about the video card like its brand, video BIOS version and video memory available. 2. Display the BIOS version and copyri ...

Another such posting came from an elderly man who was angered by all the minorities and foreigners moving into his neighborhood and pleaded to any white supremacy group to come and exterminate them. Should these people have the right to say these things? Concerns such as these have led many to demand that hate material be removed from the net. Some Internet Service Providers are already starting to block access to sites they see as harboring extreme material. Why is this happening? Have we all lost the ability to reason for ourselves? People are quite capable of making up their own ...

... operated by the government, which gives them the obligation to restrict the materials available through it. Though it appears to have sprung up overnight, the inspiration of free-spirited hackers, it in fact was born in Defense Department Cold War projects of the 1950s.2 The United States Government owns the Internet and has the responsibility to determine who uses it and how itis used. The government must control what information is accessible from its agencies. This material is not lawfully available through the mail or over the telephone, there is no valid reason these perverts should be allowed unimpeded on the Internet.

... looking documents such as memoranda, letters, reports, and resumes. With a word processor, one can easily revise a document. To improve the accuracy of one's writing, word processors can check the spelling and the grammar in a document. They also provide a thesaurus to enable a user to add variety and precision to his or her writing. Many word processing programs also provide desktop publishing features to create brochures, advertisements, and newsletters. An electronic spreadsheet enables a user to organize data in a fashion similar to a paper spreadsheet. The difference is the user does not have to perform calculations manually; electronic spreadsheets ...

... academic access to high powered computers formerly available to only the United State's military (Krol). The National Science Foundation then built its own network chaining more universities together. Later, the network connections were being used for purposes unrelated to the National Science Foundation's idea such as the universities sending electronic mail (today, it is understood as Email). The United States government then helped pushed the evolution of the Internet, calling the project: Information Super Highway (Groiler..). In the early 1990's the trend then boomed. Businesses soon connected to the Internet, and started using the In ...

One of the largest controversial topics included in the bill is the censorship of pornography, which now is a strenuously enforced crime of distributing knowingly to children under 18. The congress overwhelmingly passed the bill with a landslide 414-16 House vote and a 91-5 Senate vote.2 It seems now that the wide bill might not be what it cracked up to be, as it stands now, anyone who might upload James Joyce's Ulysses could be placed in jail for two years and have up to a $250,000 fine.3 Representatives of on-line services industrie ...
