... when you opened your bank account. If the two match, you can withdraw money. You won’t have to look into a viewfinder, or even open your eyes wider than normal. The cameras work at a range up to 3 feet away, and only take two to four seconds to find, photograph and match your iris. The security benefits are obvious: no two people, not even identical twins, have the same iris. While cards and PINs can be stolen, irises cannot. Van Naarden says iris-scanning is also being used overseas at teller windows, kiosks, vaults, and safety deposit boxes.

... users to make computations using a system of sliding beads arranged on a rack. Early merchants used the abacus to keep trading transactions. But as the use of paper and pencil spread, particularly in Europe, the abacus lost its importance. It took nearly 12 centuries, however, for the next significant advance in computing devices to emerge. In 1642, Blaise Pascal, the 18-year-old son of a French tax collector invented what he called a numerical wheel calculator to help his father with his duties. This brass rectangular box, also called a Pascaline, used eight movable dials to add sums up to eight figures long. Pascal's device used a base of ten to accomplish t ...

... to learn how to use technological devices so that they are provided with the benefits of new technology. These benefits include a greater diversity in employment opportunities and an inclusion in the educational, social and recreational activities available on the "information highway". Researchers and educators today recognize four types of technology: the technology of teaching, medical technology, instructional technology, and (Blackhurst & Cross, 1993): · The technology of teaching includes systematically designed procedures and strategies that are applied in precise ways. They typically include well-defined objectives; precise instructional procedu ...

... and personal computer limitations will hold usable rates at or below 2 Mbps for some time. ADSL offers higher security and reliability profiles. Both technologies are at about the same state of maturity and integration. Cable modems may offer a less expensive network solution because of its shared architecture, but that differential is more than offset by infrastructure costs required to upgrade existing networks. The largest advantage of ADSL, and it is a significant one, is the number of telephone lines already installed that can support ADSL, or prospectively available with network upgrades. Today the global ratio is in the order of 400 million to 6 million, o ...

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 copyright notice in upper middle screen. You will see a large sequence of numbers at the bottom of the screen. This sequence is the . 3. Display memory cou ...

... "programming" rules that the user must memorize, 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 (Soma, 32). In the early 1800's, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer would need. It wa ...

... briefcase left on a desk picked at random in one of hundreds of offices. In the same way that you would have to walk through the building, opening doors one at a time to find the briefcase, an ordinary computer has to make it way through long strings of 1’s and 0’s until it arrives at the answer. But what if instead of having to search by yourself, you could instantly create as many copies of yourself as there were rooms in the building all the copies could simultaneously peek in all the offices, and the one that finds the briefcase becomes the real you, the rest just disappear. – (David Freeman, discover ) David Deutsch, a physicist at Oxford University, argued t ...

... jobs are paying well, proving that highly skilled labor is what employers want! "There is clear evidence that the supply of workers in the [unskilled labor] categories already exceeds the demand for their services," says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. "The danger of the information age is that while in the short run it may be cheaper to replace workers with technology, in the long run it is potentially self-destructive because there will not be enough purchasing power to grow the economy," M. B. Zuckerman. My feeling is that the trend from unskilled labor to hi ...

... using very high-tech computers and engineering programs. These computers are some of the most high tech, powerful computers available anywhere in the world. It takes many of these engineers to produce a car and typically each engineer has a specific job, such as the car's frame. These engineers work independently on their assigned tasks, but they all are aware of what the other engineers are working on. This is because all of the work each engineer produces must work in unison with the work their colleagues are doing so that all the work produced functions as one; as an automobile. Another important factor in the production of an automobile is safety. Ther ...
