Internet Apps and Services

Internet Apps and Services

Although the hardware components in the Internet infrastructure can often be used to support other software systems, it is the design and standardization process of software that characterizes the Internet and provides the foundation for its scalability and success. The Internet Engineering Task Force (IETF) is responsible for the architectural design of Internet software systems. The IETF conducts standard settings working groups, open to anyone, on various aspects of Internet architecture. 

The resulting contributions and criteria are published as Request for Comments (RFC) documents on the IETF website. The main methods of networking that enable the Internet are contained in specially designated RFCs that contain Internet standards. Other less rigorous documents are merely informational, empirical or historical, or document best current practices (BCP) when implementing Internet technologies.

Applications and Services

The Internet has many applications and services, primarily the World Wide Web, which includes social media, electronic mail, mobile applications, multiplayer online games, Internet telephony, file sharing, and streaming media services.

Most of the servers that provide these services are hosted in data centers today, and content is often accessed through high-performance content delivery networks.

World Wide Web:

The World Wide Web is a global collection of documents, images, multimedia, applications, and other resources that are logically interconnected by hyperlinks and referenced with Uniform Resource Identifiers (URIs), which refer to global naming conventions. URIs symbolically identify services, web servers, databases, and the documents and resources they may provide. Hypertext Transfer Protocol (HTTP) is the main access protocol of the World Wide Web. Web services use HTTP for communication between software systems for information transfer, business data and logistic sharing and exchange, and it is one of the many languages ​​or protocols that can be used for communication on the Internet.

World Wide Web browser software, such as Microsoft’s Internet Explorer/Edge, Mozilla Firefox, Opera, Apple’s Safari, and Google Chrome, allow users to navigate from one Web page to another through hyperlinks embedded in documents.

These documents may contain any combination of computer data, including moving graphics, sounds, text, video, multimedia and interactive content, as users interact with the page. Client-side software may include animation, games, office applications, and scientific demonstrations. Through keyword-driven Internet research using search engines such as Yahoo!, Bing, and Google, users worldwide have easy, quick access to a wide and diverse range of online information. Compared to print media, books, encyclopedias, and traditional libraries, the World Wide Web has enabled the decentralization of information on a large scale.

The Web has enabled individuals and organizations to publish ideas and information to large audiences online at much lower cost and time lag. Building a web page, blog, or website involves little initial cost and there are many free services available. However, publishing and maintaining large, professional web sites with attractive, diverse and up-to-date information is still a difficult and expensive proposition. Many individuals and some companies and groups use web logs or blogs, which are often used as online diaries that can be updated. Some commercial organizations encourage staff to communicate advice in their areas of expertise in the hope that visitors will be impressed by expert knowledge and free information and will be attracted to the company as a result.
