Quantum Computers Fact -or- Fantasy?
.... 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 that it may be possible to build an extremely powerful computer based on this peculiar reality. In 1994, Peter Shor, a mathematician at AT&T Bell Laboratories in New Jersey, proved that, in theory at least, a full-blown quantum computer could factor even the l .....

The Internet: How It Works And How It Effects The World
.... traffic to be routed from one net to another as needed. All the networks connected by IP in the Internet speak IP, so they can all exchange messages." (Levine 12)
Even though there were only two networks at that time, IP was made to allow thousands of networks. The IP is designed so that every computer on an IP network is compatible. That means any machine can communicate with any other machine.
The Internet, also called the Net, is the world's largest computer network. The Internet is the "network of all networks." (Levine 7) The networks are connected to big companies like AT&T, as well as to home computers. About 1, .....

Exploring The Career Of A Computer Programmer
.... programmers from other computer specialist since job titles shift so rapidly, reflecting new areas of specialization or changes in technology. Job titles and descriptions also may vary depending on the organization. In this paper, "computer programmer" refers to individuals whose main job function is programming; this group has a wide range of responsibilities and educational backgrounds. ( Eberts 12 )
Computer programs tell the computer what to do, such as which information to identify and access, how to process it, and what equipment to use. Programs vary widely depending upon the type of information to be accessed or .....

Cable Modems And ADSL
.... 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, or about 60 to 1. Aggressive upgrades will not improve the ratio to better than 10 to 1 in the next five or six years. Even in the United States the ratio today is in the order of 20 to 1, and will not likely get better for CATV sup .....

Global Positioning Systems
.... Better yet, take a cut from a third DME transmitter and draw a third circle on your chart. Now you'd have three intersecting circles and your position would be inside the little triangle formed by the intersection of the three circles. Got the picture? This is basically how GPS triangulates, except that instead of circles, we're dealing with intersecting spheres.
TIMING IS EVERYTHING Think of GPS satellites as floating DME stations. They move along in orbit and that complicates things but forget about that for the moment. How can we measure distance?
The satellites in the GPS are some 10,900 miles up, but they're not .....

The Computer And Mass Communication
.... me - surrounding us all.
But the electronic part of the information infrastructure is only a tiny fraction of what's available to me. Every morning the newspaper is thrown into the driveway. The paper is an amazing achievement, more than one hundred pages of news, data, photographs, and advertisements pulled over electronic threads from around the world, processed, organised, and delivered. Every day at about noon the mailman brings mail to the box at the end of the driveway. It has been collected, sorted, moved, and delivered: a traditional information stream, but an important one.
Behind me as I sit in my bedroom is .....

MMX Technology
.... even non-MMX applications, and it makes use of Single Instruction Multiple Data (SIMD) for more efficient data processing. The 57 new and powerful instructions are specifically designed to process and manipulate audio, video, and graphical data much more effectively. Intel, having doubled its on-chip cache size from 16 KB on non-MMX processor chips to 32 KB on MMX enhanced chips, now allows more instructions and data to be stored on the chip reducing the number of times the proces! sor must access slower, off-chip memory areas for information. The multimedia and communication applications of today often use repetitive loops tha .....
