The Internet has undergone tremendous changes, from a collection of static corporate Web pages to an instant interactive Web. A revolution is imminent and will bring changes in usage patterns and economic models. The driving factors behind it are a new class of user-friendly, task-specific electronic products that are easy to create, and devices that can analyze Web information and quickly obtain the information they need. In other words, the device can be optimized according to the usage environment, resulting in an innovative product and service called the contextual web as a whole.
The reason for the rise of such new products and services is the result of the combined effects of the necessary ready-made technologies and the lower entry threshold for providing Internet-related software and services. In the fierce competition, technology-based companies are constantly participating in the continuous evolution of Web-based services in the fierce competition and attracting users, but many companies are used to free access to the The data failed to generate a source of income. Adding a new hardware component (information appliance) can achieve a complete product experience and make consumers feel that they are worth the price.
Consumers become participants
During the initial Internet boom, information was generally obtained by reading Web pages or downloading files, and content was provided by institutions, companies, or individuals running a given website. Users enjoy one-way service and obtain ready-made information.
The emergence of interactive and participatory functions available to a large number of users a few years ago marked a major transformation to Web 2.0. From this point on, users can communicate in two directions on the Web page to create and share content. Typical examples of user-driven Web sites include YouTube, Facebook, MySpace, Wikipedia, Flickr, and Digg. In the past few years, due to the enhancement of interactive features, the Web has significantly changed the way people connect with family, friends and colleagues.
Although the amount of data from different sources is increasing, users continue to work in the "walled garden". The term "walled garden" refers to isolated islands of applications and information. For example, data provided to the social network Facebook is generally separate from data provided to other social networking sites or professional websites. Users manage each website separately, logging in to private data, providing different groups of "friends", and only accessing data from one site at a time.
Attempts to unify high-wall isolation information through APIs are being limited by service provider business models because they want to control the appearance of portals in user interfaces to generate advertising revenue. A more original solution is to place ads a bit more prominently in the middle of the content, but the fundamental competition for consumers ’limited attention actually creates an obstacle between consumers and the information that is most valuable to them.
At present, it is technically possible to realize the free sharing of valuable data among users who are also content creators. OpenStreetMap.org is an example that allows consumers to update the map using GPS logs and an interactive session with their web browser. Over time, the data it generates can provide a valuable resource without having to share the entire cost burden with any individual or organization.
Information appliances can help consumers contribute to Web data on the one hand, and allow consumers to make full use of the data on the Web. The focus of this device is the user experience, which accelerates the creation of valuable data into the information services provided.
Semantic Web
The Semantic Web is a fundamental effort to dismantle the "walled garden" high wall and support the simultaneous use of all information. Today, individuals can access Web pages, quickly interpret their content, and determine whether they have information of interest. When looking for general information, many people will not patiently search each Web site on the search engine completely, but only view the initial results. Since only looking at the earliest results, the probability that consumers find websites that meet their needs is limited. Now this situation can be avoided, because the basic technology that has been provided allows the computer to search the entire Web according to predetermined specifications to find user-related information.
Ideally, the next important step is to run the network as a large-scale application, so that it can access various texts, images, videos, and other information without location restrictions. This is the ultimate "dream" of the Semantic Web (also known as Web 3.0), that is, all content on the Web can be accessed as if it were stored in a giant database. In this vision, specialized search engines, electronic devices, or appliances can not only understand all content across all Web sites, but also analyze and present all information disseminated on the Web in a customized, user-friendly way.
By putting all Internet content into the Semantic Web Framework, applications can understand how to use database entries to extract information, and even use access control to help users rule out the hassle of a large number of simple tasks such as cutting and copying information. When customers synchronize and publish your photos on social web sites such as MySpace, Facebook, or Flickr, all eligible recipients can receive notifications and data on demand without using specific services. And these photos do not need to manually click to download, because it integrates the corresponding photo management application technology.
It is worth mentioning that the Semantic Web itself is not an application or a physical device; it is what is expressed by adopting a set of evolving specifications. It can help people and devices find and use information on the Web, but there must be a common vocabulary between the information library and data extraction hardware or software. Only with a consistent vocabulary can we search for unlimited resources to help information consumers—even machines focus on important information without having to think about what source or type of material it is.
According to the classification of the shape, Telephone Cable have Round Telephone Cable and Flat Telephone Cable.The slim telephone cable is one of the round telephone cable.
The common specification of slim telephone cable has two core and four core, the wire diameter has 0.4 and 0.5 respectively, some areas have 0.8 and 1.0.In addition to the two and four cores, there are four, six, eight, and ten cores.
If the general family is the local telephone use mode, 2 chip is enough to use.If the telephone is used by a company or part of a group, it is recommended to use a 4-cell line in consideration of the need for telephone broadband, and a 6-cell line is recommended if a digital telephone is used.
