WEB HOSTING AND INTERNET SERVICES

There are many good web hosting services in the market, and many of them price their services at an affordable rate. They differ however according to what modalities that are including in the basic packages and how they are prizing extra modalities or finesses. They may also have restrictions on what types of web-sites they will host. Therefore it is necessary to look at more than just one web-host before one decides which to use. It is also wise not to lay all websites one owns at the same host of security reasons, because any-web host can experience a major brake-down, even the very best and most expensive ones.

WVC54GC Wireless-G Internet Video Camera

"The Linksys Compact Wireless-G Internet Video Camera sends live video through the Internet to a web browser anywhere in the world! This compact, self-contained unit lets you keep track of your home, your kids, your workplace -- whatever's important to you. Unlike standard "web cams" that require an attached PC, the Internet Video Camera contains its own web server, so it can connect directly to a network, either over Wireless-G (802.11g) networking, or over 10/100 Ethernet cable. The advanced MPEG-4 video compression produces a high-quality, high-frame rate, up to 320x240 video stream." The Compact Internet Video Camera's unique form-factor and wireless connectivity allows you to mount it on a wall nearly anywhere, or slip it into its included stand for desktop use. Once it's connected to your home network, you can "see what it sees" from any Windows-based PC in the house, while the video stream is secured from the outside world, hidden behind your Router. If you want the video to be visible from outside your home network, you can open an appropriate port on the Router, and then create password protected accounts to manage access to the camera, or leave it wide open for the world to see. The SoloLink domain service (trial sign-up included) lets you access your camera using an easy-to-remember "name", even if your home Internet connection uses a dynamic IP address.

Some important internet online services explained

eBay.com - Ebay is an international online auction service. Users having an acount at ebay can set inn offerings for things they want to sell, either in an online auction or advertize it for a fixed prize. Other users an then bid on the item throug eBay. Ebay provides all contact and payment services for the seller and the bidder. eBay also sells several items from companies with which they have licensing deals. eBay is intimately connected with the payment service PayPal which is owned by the same company as eBay.

The online auction web site was founded in San Jose, California on September 3, 1995 by computer programmer Pierre Omidyar as AuctionWeb, part of a larger personal site that included, among other things, Omidyar's own tongue-in-cheek tribute to the Ebola virus.

The very first item sold on eBay was a broken laser pointer for $14.83. Astonished, Omidyar contacted the winning bidder and asked if he understood that the laser pointer was broken. In his responding email, the buyer explained: "I'm a collector of broken laser pointers." The frequently repeated story that eBay was founded to help Omidyar's fiancée trade PEZ Candy dispensers was fabricated by a public relations manager in 1997 to interest the media. This was revealed in Adam Cohen's 2002 book and confirmed by eBay.

The company officially changed the name of its service from AuctionWeb to eBay in September 1997. The company purchased PayPal in October 2002.

Google.com - Google is a general internet service provider. The search enine is the most famous part of google featuring general text search, picture search, video search, geographically search and planetary search.. It also provides discussion phora, newsgroups and news provider services.Google provides paid advertising services, and this is the source of revenue for the owners of Google.

Google began as a research project in January 1996 by Larry Page and Sergey Brin, two Ph.D. students at Stanford University, California. They hypothesized that a search engine that analyzed the relationships between websites would produce better results than existing techniques, which ranked results according to the number of times the search term appeared on a page. Their search engine was originally nicknamed, "BackRub" because the system checked backlinks to estimate a site's importance. A small search engine called Rankdex was already exploring a similar strategy.

In March 1999, the company moved into offices at 165 University Avenue in Palo Alto, home to several other noted Silicon Valley technology startups. After quickly outgrowing two other sites, the company leased a complex of buildings in Mountain View at 1600 Amphitheatre Parkway from Silicon Graphics (SGI) in 1999.The company has remained at this location ever since, and the complex has since become known as the Googleplex (a play on the word googolplex, a 1 followed by a googol of zeros). In 2006, Google bought the property from SGI for $319 million.

The Google search engine attracted a loyal following among the growing number of Internet users, who liked its simple design. In 2000, Google began selling advertisements associated with search keywords. The ads were text-based to maintain an uncluttered page design and to maximize page loading speed. Keywords were sold based on a combination of price bid and clickthroughs, with bidding starting at $.05 per click. This model of selling keyword advertising was pioneered by Goto.com (later renamed Overture Services, before being acquired by Yahoo! and rebranded as Yahoo! Search Marketing). While many of its dot-com rivals failed in the new Internet marketplace, Google quietly rose in stature while generating revenue.

Hotmail - Hotmail is the mail service originally provided by microsoft and incorporated in the total MSN service. New services has now replaced Hotmail, but those new one are also commonly called "Hotmail", and the email adress still have the formate "XXX.@hotmai.com". The Hotmail webmail service was amongst the first (as of May 7th, 2007 it is being replaced by Windows Live Hotmail), followed by the instant messenger service MSN Messenger, which has recently been replaced by Windows Live Messenger.

Mapquest .com - MapQuest is a map publisher and a free online Web mapping service owned by AOL. The company was founded in 1967 as Cartographic Services, a division of R.R. Donnelley & Sons in Chicago, Illinois. It moved to Lancaster, Pennsylvania in 1969. When it became an independent company in 1994, it was renamed GeoSystems Global Corporation. MapQuest was acquired in 2000 by America Online, Inc.

Donnelley began making maps with computers in the mid-1980's to generate maps for customers. Much of that code was adapted for use on the Internet to create the MapQuest web service in 1996. In 1999 the company was renamed to MapQuest to leverage the popularity of its online brand. For a while, MapQuest included satellite images, but later removed them. In September 2006, the web site once again began serving satellite imagery in a new beta program.

In 2004, MapQuest, uLocate, Research in Motion and Nextel launched MapQuest Find Me, a buddy-finder service that works on GPS-enabled mobile phones. MapQuest Find Me lets users automatically find their location, access maps and directions and locate nearby points of interest including airports, hotels, restaurants, banks and ATMs. Users also have the ability to set up alerts to be notified when network members arrive or depart from a designated area. In 2005 the service became available on Sprint and in 2006, Boost Mobile.

In July 2006, MapQuest created a beta version of a new feature in which users could now "Build Your Route" by adding additional stops, reorder one's route (and the stops along the way), and avoid any turn or road en route.

In April 2007, MapQuest announced a partnership with General Motors' OnStar that will allow OnStar subscribers to plan their driving routes on MapQuest.com and send their destination right to OnStar's Turn-by-Turn Navigation service. The OnStar Web Destination Entry pilot program will begin the summer of 2007 with a select group of OnStar subscribers.

MySpace.com - MySpace is a popular social networking website offering an interactive, user-submitted network of friends, personal profiles, blogs, groups, photos, music and videos internationally. It is headquartered in Beverly Hills, California, USA,[1] where it shares an office building with its immediate owner, Fox Interactive Media; in turn, the owner of Fox Interactive (and therefore MySpace), News Corporation, is headquartered in New York City.

According to Alexa Internet, MySpace is currently the world's sixth most popular English-language website and the sixth most popular website in any language,[2] and the third most popular website in the United States, though it has topped the chart on various weeks[3]. The service has gradually gained more popularity than similar websites to achieve nearly 80% of visits to online social networking websites.[3] It has become an increasingly influential part of contemporary popular culture, especially in English speaking countries.[citation needed]

The company employs 300 staff[4] and does not disclose revenues or profits separately from News Corporation. With the 100 millionth account being created on August 9, 2006,[5] in The Netherlands[6] and a news story claiming 106 million accounts on September 8, 2006,[7] the site reportedly attracts new registrations at a rate of 230,000 per day.

MSN.com - MSN (short for Microsoft Network) is a collection of Internet services provided by Microsoft. Initially released on August 24, 1995, to coincide with the release of Windows 95. The range of services provided has changed significantly since its release. The Hotmail webmail service was amongst the first (as of May 7th, 2007 it is being replaced by Windows Live Hotmail), followed by the instant messenger service MSN Messenger, which has recently been replaced by Windows Live Messenger. According to Alexa.com, MSN.com is currently ranked 2nd amongst all websites for Traffic Rank.[1]

In large part, MSN was rebranded in 2005 to Windows Live, which saw the release of Windows Live Hotmail (previously Windows Live Mail) and Windows Live Messenger. Microsoft overhauled its online software and services in a climate of increasing competition from rivals such as Google, and Yahoo!. The Windows Live brand is currently being rolled out service-by-service, with rebranded services being classed as Beta tests initially. It is anticipated that the MSN service will aim at the personal and family user, whilst Windows Live will be a dedicated search facility for various media.

In the United States and Canada, MSN is not only a content provider and search engine, it is additionally an Internet Service Provider. With around 9 million subscribers, MSN is the second largest Internet Service Provider in the United States behind AOL service with about 26.5 million. In other countries, MSN uses underwriters for their services; in the UK, Microsoft use BT group.

The term "MSN" has come to be synonymous with MSN Messenger in Internet slang. To use MSN services, users must have a Windows Live ID account, an account system which allows access to all of the MSN facilities. One can sign-up using any e-mail address, and can then use personalized MSN and Windows Live features requiring the use of a Windows Live ID. These personalized features include My MSN, MSN Hotmail (now Windows Live Hotmail) and the ability to sign into Windows Live Messenger, and the now retired (as from Windows Vista) Windows Messenger. As of 2007, MSN has more than 225 million users.

Pogo.com - Pogo.com is a popular gaming website that offers a variety of free casual games, from card and board games to puzzle, word, and sports games. The website is free, but a premium subscription-based service called "Club Pogo" also exists.

Pogo.com is consistently a top-10 Internet site for U.S. visitors when measured by time spent online. It was ranked #7 in December, 2006[1] and #6 in January, 2007[2] by Compete.

Some of Pogo.com's competitors for casual and social gamers include Yahoo! Games, Viacom's Neopets, Yohoho! Puzzle Pirates and TrayGames.

Yahoo.com - Yahoo! Incorporated (NASDAQ: YHOO) is an American public corporation and global internet services company. It operates an internet portal and provides a full range of products and services including a search engine, the Yahoo! Directory, Yahoo! Mail, news, posting, etc. It was founded by Stanford University graduate students Jerry Yang and David Filo in January of 1994 and incorporated on March 2, 1995. The company is headquartered in Sunnyvale, California.

According to web traffic analysis companies (including Alexa Internet and Netcraft), Yahoo! has been the most visited website on the Internet, with more than 412 million unique users. The global network of Yahoo! websites received 3.4 billion page views per day on average as of October 2005, making it one of the most visited U.S. websites.

It primarily competes against Google, MSN and AOL among others.

In January 1994, Stanford graduate students Jerry Yang and David Filo created a website named "Jerry's Guide to the World Wide Web". Jerry's Guide to the World Wide Web was a directory of other web sites, organized in a hierarchy, as opposed to a searchable index of pages.

In April 1994, "Jerry's Guide to the World Wide Web" was renamed "Yahoo!". Filo and Yang said they selected the name because they liked the word's general definition, as in Gulliver's Travels by Jonathan Swift: "rude, unsophisticated, uncouth." The name can also be a backronym for "Yet Another Hierarchical Officious Oracle". Its URL was akebono.stanford.edu/yahoo.

By the end of 1994, Yahoo had already received one million hits. Yang and Filo realized their website had massive business potential, and on 2 March 1995, Yahoo was incorporated.[5] On 12 April 1996, Yahoo had its initial public offering, raising $33.8 million dollars, by selling 2.6 million shares at $13 each.
