A URL (Uniform Resource Locator, previously Universal Resource Locator) - is the unique address for a file that is available on the Internet. A general way to get to a Web site is to enter the URL of its home page file in your Web browser's address line. Though, any file inside that Web site can also be particular with a URL. Such a file might be some Web (HTML) page other than the home page, an image file, or a program such as a frequent entry interface application or Java applet. The URL contains the name of the protocol to be used to access the file resource, a domain name that identifies a exact computer on the Internet, and a pathname, a hierarchical description that specifies the place of a file in that computer.

Fresh vegetables
Try something new. You may find that you love grilled vegetables or steamed vegetables with an herb you haven't tried like rosemary. You can sauté vegetables in a non-stick pan with a small amount of cooking spray. Or try frozen or canned vegetables for a quick side dish — just microwave and serve. When trying canned vegetables, look for vegetables without added salt, butter, or cream sauces. Commit to going to the produce department and trying a new vegetable each week.

Ring network
A ring network is a network topology in which each node connects to exactly two other nodes, forming a single nonstop path for signals through each node - a ring. Data travels from node to node, with each node along the way action every packet.
Because a ring topology provides only one pathway between any two nodes, ring networks may be disrupted by the breakdown of a single link. A node breakdown or cable break might separate every node attached to the ring. FDDI networks conquer this susceptibility by sending data on a clockwise and a counterclockwise ring: in the occasion of a break data is wrapped back onto the complementary ring previous to it reaches the end of the cable, maintaining a path to every node the length of the resulting "C-Ring". 802.5 networks -- also known as IBM Token Ring networks -- avoid the weakness of a ring topology altogether: they really use a star topology at the physical layer and a Multistation Access Unit to copy a ring at the datalink layer.
Many ring networks put in a "counter-rotating ring" to form a redundant topology. Such "dual ring" networks include Spatial Reuse Protocol, Fiber Distributed Data Interface (FDDI), and Resilient Packet Ring.

Resort
A resort is a place used for relaxation or recreation, attracting visitors for holidays or vacations. Resorts are places, towns or sometimes profitable organization operated by a single company. Such a self-contained resort attempts to give for most of a vacationer's wants while residual on the premises, such as food, drink, lodging, sports, entertainment, and shopping. The term "resort" sometimes is distorted to identify a hotel that does not provide the other amenities required of a full resort. However, a hotel is often a central characteristic of a resort, such as the Grand Hotel at Mackinac Island, Michigan. A resort is not just a commercial establishment operated by a single company, though in the late twentieth century this sort of ability became more common.

Aviation Innovators Compete for NASA Technology Prizes
The 2008 General Aviation Technology Challenge will be held Aug. 4-10 at the Sonoma County Airport in Santa Rosa, Calif. Competitors will demonstrate innovations resulting in aircraft that are safer, less expensive and easier to operate, while having fewer negative impacts on the environment and communities surrounding airports.
This year's competition will feature the first Green Prize for aviation. The highlight of the week-long event will occur Saturday, Aug. 9, with the CAFE 400 - a 400-mile, cross-country air race that requires speed and efficiency.
The Comparative Aircraft Flight Efficiency (CAFE) Foundation based in Santa Rosa manages this challenge for NASA. The total purse for 2008 is $300,000, which will be divided among the following prizes:
- The Community Noise Prize
- The Green Prize (for the highest miles per gallon)
- The CAFE Safety Prize (for handling and electronic safety features)
- The CAFE 400 Prize
- The Quietest Light Sport Aircraft Prize
The General Aviation Technology Challenge is one of seven current NASA technology prize competitions. The prize program, which began in 2005, is known as Centennial Challenges in recognition of the centennial of powered flight. In keeping with the spirit of the Wright Brothers and other American innovators, Centennial Challenge prizes are offered to independent inventors who work without government support, including small businesses, student groups and individuals.
The prize competitions are targeted at a range of technical challenges that support NASA's missions in aeronautics and space. The goal is to encourage novel solutions from non-traditional sources. In the Centennial Challenge program, NASA provides the prize money, and each of the competitions is managed by an independent organization.
NASA's Innovative Partnerships Program Office manages the Centennial Challenges program. For more information on the Centennial Challenges, visit:

Web page design
Web page design is a process of conceptualization, planning, modeling, and execution of electronic media content release via Internet in the form of technologies (such as markup languages) suitable for understanding and display by a web browser or other web-based graphical user interfaces (GUIs).
The intent of web design is to make a web site (a collection of electronic files residing on one or more web servers) that presents content (including interactive features or interfaces) to the end user in the form of web pages once requested. Such elements as text, forms, and bit-mapped images (GIFs, JPEGs, PNGs) can be placed on the page using HTML, XHTML, or XML tags. Displaying more complex media (vector graphics, animations, videos, sounds) typically requires plug-ins such as Flash, QuickTime, Java run-time environment, etc. Plug-ins are also embedded into web pages by means of HTML or XHTML tags.

India’s first unmanned Spacecraft
The great achievement by the Indian scientist is launched the chandrayaan space craft in lunar orbit. Chandrayaan-1 was launched October 22 into Earth orbit, and slowly raised its zenith until it moved into a transfer path. Chandrayaan-1, with 11 scientific instruments - 6 foreign and 5 Indian -- is the first spaceship operation on beyond Earth orbit. The box-shaped lunar probe carried a video imaging system, a radar altimeter and a mass spectrometer. Which is successfully put into the Lunar orbit by the ISRO(Indian Space Research Organization).It Entered the Lunar orbit at November 15th Saturday in 2008. If the moon mission is successful,
