Wireless gear

Wireless gear touches our lives in surprising ways. It’s not just computers and phones these days there’s wireless in everything from TVs and audio systems to planes, trains, and automobiles. To help you wrap your mind around the expanse of wireless, we take the time in this Part to lay out a vision of the wireless world. We talk
about where you find wireless and what flavor of wireless you can expect to find in each device and place. Then we spend some time looking at the nitty-gritty details about the standards and certifications — explaining key concepts like 802.11 and Wi-Fi — so that you’ll understand
exactly which pieces of wireless gear work together, and which don’t. We also review the pieces and parts that make up a wireless network. If you’ve already got a wireless network in place, you can skim through this quickly it’s always there for you to refer back to if you want. Finally, we review the equipment and services you need to connect your wireless networks to the Internet. Don’t underesti-mate the importance of this step — the value of your net-works increases exponentially as they are connected to other networks.

China as top carbon polluter

The research suggests the country's greenhouse gas emissions have been underestimated, and probably passed those of the US in 2006-2007.
Until now it has been generally believed that the US remains "Polluter Number One".

Next month's University of California report warns that unless China radically changes its energy policies, its increases in greenhouse gases will be several times larger than the cuts in emissions being made by rich nations under the Kyoto Protocol.

The researchers say their figures are based on provincial-level data from the Chinese Environmental Protection Agency.

You can also use a good expired domain name to build a web site, develop it with good content and later sell them at premium rates to any interested parties. These are some of the simple methods that allow you to use the hidden power of domains expired to make a large pool of income. If you are careful enough in using your expired domains, you can earn a hefty profit and a sustained residual form of income.

Domain in science

Domain is the distinguished part of an abstract or physical space where something exists, is performed, or valid. For example, we may talk about: domain of interest, domain of activity. This concept is used in every branch/sector/field of human activity.

In biology, domain (also superregnum, superkingdom, or empire) is the top-level taxon of organisms in scientific classification, higher than a kingdom. Domain (or its synonyms) is the most inclusive of these biological groupings

In mathematics, a domain of a k-place relation L ⊆ X1 × … × X'k is one of the sets X'j, 1 ≤ j ≤ k
and can define to as:
In abstract algebra, a domain is a ring with 0 ≠ 1 such that ab = 0 implies that either a = 0 or b = 0 (the zero-product property). That is, it is a nontrivial ring without left or right zero divisors.

But ussualy we know domain as :
The address of a site, without the protocol, path, page or other items attached. For example, microsoft.com is a domain, however, a full URL could be http://www.microsoft.com/stuff/page.html
