Cat 5e and Cat 6 Differences and Benefits
Bandwidth precedes data rates just as highways come prior to traffic. Doubling the bandwidth is like adding two times the number of lanes on a highway. The trends of the past and the predictions for the future indicate that rates have been doubling every 18 months.
Current applications running at 1 Gb/s are really pushing the limits of category 5e cabling. As streaming media applications such as video and multi-media become common, the demands for faster data rates will increase and create new applications that will benefit from the higher bandwidth offered by category 6. This is exactly what happened in the early 90s when the higher bandwidth of category 5 cabling compared to category 3 caused most lan applications to choose the new media to allow simpler, cost effective, higher speed lan applications, such as 100BASE-TX. Note: Bandwidth is defined as the highest frequency up to which positive power sum ACR (Attenuation to Crosstalk Ratio) is greater than zero.
The general difference between category 5e and category 6 is in the transmission performance, and extension of the allowed bandwidth from 100 MHz for category 5e to 200 MHz for category 6. This includes better insertion loss, near end crosstalk (NEXT), return loss, and equal level far end crosstalk (ELFEXT). Improvements, such as described, provide a higher signal-to-noise ratio, allowing greater reliability for current applications and higher data rates for future applications.
Category 6 will eventually supercede category 5e. Analyst predictions and independent polls indicate that 85 to 95 percent of new installations will be installed with category 6. The fact that category 6 link and channel requirements are backward compatible to category 5e makes it quite easy for customers to choose category 6 and supersede category 5e in their networks. Applications that worked over category 5e will still work over category 6.
Because of its greater transmission performance and better immunity from external noise, systems operating over 6 cabling will have fewer errors vs. category 5e for current applications. This means fewer re-transmissions of lost or corrupted data packets under certain conditions, which translates into higher reliability for category 6 networks compared to category 5e networks. Category 6 will be very effective in the residential market to support higher internet access speeds while facilitating the more stringent class B EMC requirements (see also the entire FCC Rules and Regulations, Title 47, Part 15). The better balance of category 6 will make it easier to meet the residential EMC requirements compared to category 5e cabling. Also, the growth of streaming media applications to the home will increase the need for higher data rates which are supported more easily and efficiently by category 6 cabling.

Getting Hearts and Hands Ready for the Holidays
"At Christmas play and make good cheer, For Christmas comes but once a year." -Thomas Tusser
OK. Thanksgiving was wonderful, visiting with family and sharingfun stories and adventures; laughing around the dining roomtable, enjoying favorite stuffing and pies; watching parades andfootball games; and counting your many blessings.
It is now time to turn our attention to the many preparations for Christmas. Coming from a Christian perspective, I can speak for the anticipation which we all feel to celebrate the birth of the Christ-child. It brings us wonder each and every year, and the time and energy we put into its celebration never wanes. As I watch my jewish friends prepare for Hanukkah, I sense, too, the joy with which they prepare celebrations with loved ones.
The gift of sacrificial love is the true essence of Christmas.
Teaching your children to give generously and to give cheerfullymodels the life of Christ. Our God, who created each one of uswith more love than we can imagine, desires this same outpouringof love to others, and it is at Christmas that we likewise shareour love through gift-giving and through acts of generosity andhospitality. We are buoyed by the "Christmas spirit" because itis through giving--rather than receiving--that we receive themost joy. Pausing to think about others, about their needs anddesires, and extending yourselves to their benefit, brings deepinner satisfaction not found any other way.
Have you made your list of those people with whom you want toshare the Christmas spirit?
Consider giving small, inexpensive gifts to a large list, rather than more extravagant gifts to a very few loved ones.
When Ithink of the model of giving I want to pattern for my own family, I cannot exclude from the list those folks who cross my path on a daily basis--in one way or another--who may or may not have yet reached into close friendship with me. And so I am always thoughtful for small yet kind ways in which I might extend generosity.
Extend your circle of concern.
Think not only of what members of your own family would appreciate at Christmas. Think of cousins and aunts and uncles, and of closest friends. And don't stop there. Extend your circle. Think of your mail carrier, pet groomer, your pediatrician's office staff, the folks at your gym, your neighbors, friends of your children, office workers at youor your spouse's place of work, your manicurist, thelandscaper....think through the flow of your typical week andthose people who enter your life on a regular basis. If they areserving you in some capacity, isn't it kind to remember them now?
Many people refrain from practicing generosity to those outsidetheir small circle of concern because of the lack of money withwhich to do so. But inexpensive gifts can be handmade for pennies if we will only stretch our imaginations and put our hands--and those of our children--to good use.
look to nature and to materials right outside your front door
Free for the asking and the picking: a fresh bouquet of greens--evergreens, magnolia leaves, and berries, tied with a gorgeoussilk ribbon--would be cherished by any receiver.
Tiny bird nest ornaments fashioned from spanish moss, filled with speckled beans and a silk butterfly, and with a wooden clothespin glued from underneath, make delightful gifts for children and adults alike. My own tree is filled with them.
Collect pinecones and make an arrangement with them. Yourthoughtfulness will be appreciated and it will have cost nothingmore than a walk in the woods.
Homemade candies or cookies wrapped in inexpensive cellophanebags look elegant tied with ribbon and make perfect gifts forvirtually anyone on your list.
miniature baskets filled with one tiny, simple gift, are perfect for your children's friends.
Remember: children love exaggeration; anything diminutive (or enormous!) appeals to their sense of wonder.
Homemade "snow globes" make our list every single year
Simply use a baby food or other small jar and fill it with water and a small bit of glycerin (found at your local drug store) and white glitter; add a few plastic toys--Legos, Barbie doll shoes, jacks and balls, plastic bugs--and then squeeze a think line of silicone sealant around the lid before screwing it on to prevent leakage.
Homemade glycerin soaps filled with tiny plastic toys areadorable
They'll delight your children as well, for they'll have created happy memories making them with you for all of their friends.
Consider making homemade wrapping paper or handmade gift tags.
I buy inexpensive tags at office supply stores by the hundreds.They cost about a penny apiece. I also use twine instead ofexpensive ribbon. One bolt lasts several years and costs a couple of dollars.
And mail those out-of-state gifts early to avoid long lines atthe post office as well as the extra expense of priority mail.
Model a generous life...at Christmas and throughout the year.Give faithfully and give cheerfully. You will be blessedbeyond measure.

Losing Weight with Supplements
Many consumers find that they are wasting their hard-earned money and that many of the supplements have no effect on their waistline, and the only thing that is slimming down is the wallet. Physicians warn that many unscrupulous marketers will make impossible claims in order to get buyers to walk through the virtual doors of their marketplace.
Do you know which the best dietary supplements are? Chances are, you do not know. What some consumers may consider the best weight loss supplements will have little or no effect for other consumers who try them. After all, there are so many weight loss pills on the market right now, that it is hard to understand how each of them works, and what their claims to fame are. Similarly, it is hard to know what the risks of the individual supplements are, especially since many of them are formulated quite differently from one another.
If you are trying to lose some weight, the odds are pretty good that suddenly you are paying much more attention to the television ads that tout the benefits of a host of dietary supplements. It may appear as though the floodgates have opened, because when you open your newspaper, you cannot help but see the ads for dietary supplements are there as well. Of course, the same can also be said of your email inbox.
As a matter of fact, between ephedra diet pills, ephedra free pills, and the latecomer to the bunch Hoodia it is not surprising for many dieters to simply purchase the newest addition to the market, and hope for the best. According to doctors, the best weight loss supplements are the ones that not only work, but that also will not have any counterproductive effect on medications you may already be taking, and that will also not add stress to your heart. So before taking any dietary supplements, please be safe and visit your doctor!
