... plotting and planning. Now they are beginning to conduct small forays in the laboratory, and their few successes to date lead them to believe they were on the right track. "We have a long way to go before carbon-based electronics replace silicon-based electronics, but we can see now that we hope to revolutionize computer design and performance," said Robert R. Birge, a professor of chemistry, Carnegie- Mellon University, Pittsburgh. "Now it's only a matter of time, hard work, and some luck before molecular electronics start having a noticeable impact." Molecular electronics is so named because it uses molecul ...

... it is 1900 all over again and will therefore disrupt with personal information, city functions, and banking systems. For example you have a credit card that you just got and it expires 05/02, the bank will think 05/02 means 05/1902, It is way overdue to be terminated and bam! There goes your credit card. This bug also affects other things in the city. For example, if a train is running on a track and the power cuts out, then the gates wont go down and people will be in a lot of trouble. (Also, what happens if the power goes out in a hospital? (Also see “WHAT IS Y2K� later on) Food is one essential thing tha ...

... of information, a group of such items, or computer instructions. Examples include a news item, a bank transaction, a mailing address, a letter, a book, a mailing list, a bank statement, or a computer program. The devices used can be computers, terminals (devices that transmit and receive information), and peripheral equipment such as printers (see Computer; Office Systems). The transmission line used can be a normal or a specially purchased telephone line called a leased, or private, line (see Telephone). It can also take the form of a microwave or a communications-satellite linkage, or some combination of any of ...

... links. Fortunately, the Net is not usually under enemy attack. The ARPANET was very successful, and every university in the country wanted to sign up. Because so many people wanted to use the Net, ARPANET started getting hard to manage, especially with many university sites on it. Therefore, it was broken into two parts: MILNET, which had all the military sites, and ARPANET, which had all the nonmilitary sites. "The two networks remained connected, however, thanks to a technical scheme called IP (Internet Protocol), which enabled traffic to be routed from one net to another as needed. All the networks connect ...

... very earliest existence of the modern day computer's ancestor is the abacus. These date back to almost 2000 years ago. It is simply a wooden rack holding parallel wires on which beads are strung. When these beads are moved along the wire according to "programming" rules that the user must me! morize, all ordinary arithmetic operations can be performed (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first "digital calculating machine". It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal's father who was a tax collector (S ...

... This approach required a lot of documentation, as completion of each phase was accompanied by many documents. 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 s ...

... this essay, I will examine third world communities and the relationship between technological development and environmental degradation. I will look first at the way in which development occurred in the South, and the reason it happened the way that it did. From there, I will show how these methods of development proceeded to eventually cause widespread environmental damage and it's effect on the local people. . DEVELOPMENT: "WESTERN" STYLE When I refer to "the environment", I mean not only the habitat that humans, plants and animals inhabit, but also the physical, emotional and psychological attitudes tha ...

... the problem quite well. "We programmed computers to store the date in the following format: dd/mm/yy. This only allows 2 digits for the year. January 1, 2000 would be stored as 01/01/00. But the computer will interpret this as January 1, 1900- not 2000" (de Jager 1). The '19' is "hard-coded" into computer hardware and software. Since there are only 2 physical spaces for the year in this date format, after '99', the only logical choice is to reset the number to '00'. The year 2000 problem is unlike any other problem in modern history for several reasons. William Adams points out some of the most importa ...

... Pornography is one of the, most if not the most, controversial of all these pages, but there are new ways to fight porn. One of these new programs to fight porn is Net Nanny. This program does not only filter out porn but some of the other inappropriate pages too. If kids are caught using or viewing any inappropriate content the kids are sometimes banned from using the school´s internet (Heller). If the kids keep doing this there will soon be no internet for the kids to use. The internet has many different types of pages, but of all the educational or informative pages there are always the “ black sheeps ...

... maps. Different routes are stored on one single compact-disk. Imagine, simply insert the CD into the CD-driver in your car, and tell the computer where to go. The rest will be done automatically. This will be a safer, faster, and more comfortable way to travel. Another new area, called "virtual reality" is currently being tested. This is a way to simulate reality on a monitor. In order to feel this so-called reality you have to wear special electronic glasses and an electronic suit. Fastened to the suit are sensors, which send information to the main computer. This computer works with the data and displays them on ...
