Internet Privacy

Each time a client requests a web page, the server can identify the IP address of the request and usually logs. Also, unless you do not put, most web browser files requested web pages in a feature of the visible history, and often in large cache of content locally. Unless your browser’s communication server uses HTTPS encryption, web requests and responses that travel in clear on the Internet and can be viewed, stored, and cached by intermediate systems. When a web page requires, and user supplies, personal information such as their name, address, e-mail address, etc.-based web entities can associate the actual web traffic with that person. If your site uses HTTP cookies, authentication username and password, or other monitoring techniques, you can report to other web visits before and after the provided identifiable information. This way it is possible for a web-based organization to develop and build a profile of individual people using your site or sites. It may be able to build a record for just one that includes information about their leisure activities, their business interests, their profession, and other aspects of their demographic profile. These profiles are obviously of potential interest for business sales, advertisers and others. According to the terms and conditions of the site and the local laws that apply the information from these profiles can be sold, shared, or transmitted to other organizations without the user being informed. For many ordinary people, this means a little more than a few unexpected e-mails in their inbox, or a bit of “mysteriously relevant advertising on a future page. For others, this may mean that time spent engaging in unusual interest can result in a more targeted marketing flood that may be unwelcome. Law enforcement, counterterrorism and intelligence can also identify, target and track individuals according to their interests or trends on the web.

Social networks try to get users to use their real names, interests and positions, rather than pseudonyms. These leaders believe that this makes the social networking experience more appealing to users. On the other hand, photographs or unsecured loaded statements can be identified to an individual, he may regret this exposure. Employers, schools, parents and other loved ones may be affected by aspects of social networking profiles, such as text messages or digital photos, that individual posting does not intend these hearings. Online bullies may use personal information to harass or persecute users. Modern social networking sites allow for accurate control of privacy settings for individual stations, but these can be complex and not easy to find or use, especially for beginners. Photographs and videos posted on websites have caused particular problems because they can add a person’s face to an online profile. With modern and potential facial recognition technology, it may be possible to connect this face with previously anonymous, images, events and scenarios that have been imaged elsewhere. Because of the cached image, mirroring and copying, it is difficult to remove an image from the World Wide Web.

WWW prefix

Many host names used for the World Wide Web begin with www because of the long-standing practice of naming Internet hosts based on the services they provide. The host name of a web server is often www, in the same way that it can be ftp for an FTP server, and news and NNTP for a news server Usenet. These host names appear as Domain Name System (DNS) or subdomain names, as in www.example.com. The use of the web is not required by a technical or policy standard and many websites do not use it; In fact, the first web server ever was called nxoc01.cern.ch. According to Paolo Palazzi, who worked at CERN by Tim Berners-Lee, popular use www as a subdomain, it was accidental; On the World Wide Web project, it was intended to be published in www.cern.ch so info.cern.ch was intended to be the CERN homepage, but DNS registrations were never started and the Practice to put to www a domain name of the institute was then copied. Many established websites still use the prefix, or use other subdomain names, such as www2, secure or FR for special purposes. Many of these Web servers are set up so that the two main domain names (eg example.com) and the www subdomain (for example, www.example.com) refer to the same site; Others require one form or another, or can be mapped to different websites. The use of a subdomain name is useful for balancing incoming Web traffic by creating a CNAME record that points to a cluster of load-web servers. Since at present only one subdomain can be used in a CNAME, the same result can not be obtained by using the root of the naked domain.

When a user submits an incomplete domain name to a web browser in its address bar entry field, some browsers automatically try to add the “www” prefix at the beginning of it and maybe “. Com “,” .org “and” .net “at the end, depending on what they might be missing. For example, by entering “Microsoft”, it can be transformed into http://www.microsoft.com/ and openoffice at http://www.openoffice.org. This feature began appearing in early versions of Mozilla Firefox, when it still had the “Firebird” working title in early 2003, from a previous practice in browsers like Lynx. It is reported that Microsoft got a US patent for the same idea in 2008, but only for mobile devices.

In English, www is usually read as double u double u u double. Some users use dub-dub-dub, especially in New Zealand. Stephen Fry, in his series of podcasts “Podgrams”, wuh pronunciation Wuh wuh [citation needed] English writer Douglas Adams once joked in The Independent on Sunday (1999). “The World Wide Web is the only thing I know whose shortened form takes three times longer to say that it is the abbreviation of”. In Mandarin, the World Wide Web is usually translated as a phono-semantic correspondence WAN wǎng Wei (万维网), which satisfies www and literally means “three-dimensional network” host, a translation that reflects the concept of design and proliferation of the World Wide The Web WWW Web is officially spelled as three separate words, each capitalized, with no intermediate hyphens. Your use of the www prefix is ​​decreasing, especially when Web 2.0 Web applications have Tried to brand their domain names and make them easily pronounceable.Has gained popularity as a mobile web, services like Gmail.com, Outlook.com, MySpace.com, Facebook.com and Twitter.com are the More often quoted without adding “www.” (Or, again, “com”) to the domain.

World Wide Web

Tim Berners-Lee’s vision of a global hyperlinked information system became a possibility in the second half of 1980. In 1985 the global Internet began to proliferate in Europe and in the Domain Name System Which the Uniform Resource Locator is built), it was born. In 1988, the first direct IP connection between Europe and North America was made and Berners-Lee began to openly discuss the possibility of a web-like system at CERN. In March 1989 Berners-Lee presented a proposal for the management of CERN to a system called “Mesh” which refers to DEMAND, a database project and software that it had built in 1980, which used the term ” Web “and describes a more elaborate system based on links integrated into the management of the information readable by the text:” Imagine, then, all the references to associate with the network address of the thing to which they refer, So that when reading this document, you can switch between them with the click of a mouse “. Such a system, he explained, could be defined using one of the current meanings of the word hypertext, a word he says was invented in 1950. There is no reason, the proposition continues, because These hyperlinks could not include multimedia documents, including images, voice and video, so that Berners-Lee continues to use the term hypermedia.

With the help of his colleague and passionate hypertext Robert Cailliau published a more formal proposal November 12, 1990 to build a “Hypertext Project” called “WorldWideWeb” (a word) as a “network” of “hypertext documents” to be seen by At this point, HTML and HTTP had already been in development for about two months and the first web server was about a month away from completing its first test with Success. “This proposal estimated that a single web reading will be developed within three months and that it would take six months to achieve” the creation of new links and materials by readers, [so that] the author becomes universal “As well as” automatic notification of a reader when new material of interest to him / her has become available. “During playback of the only goal was achieved, the authorship of accessible web content took longer to Mature, with the concept of wiki, WebDAV, blog, web 2.0 and RSS / Atom.
