Published Date: 02 Nov 2017

Internet network was established more than 40 years. As often happens, the purpose of serving the needs of the military is the engine led to the birth of the internet. In the late '60s, the Department of Defense wants to connect the computers in all its agencies located at different points in the territory of the United States to ensure the coordination of activities. The military has suggested the problem with scientists. According to the order, the system must also ensure that if a part of it is separated from the general network for military attacks, can not stop the entire operation of the remaining system.

Very quickly, even in the 1970s appeared the first network bearing the ARPAnet, connecting the university in Los Angeles and Santa Barbara with Stanford University, the university in the state south of Salt -Lake-City. Only two years later, there were 40 centers located off another computer hundreds of miles can exchange information with each other. Two years later, in 1974, the first two technical solutions by which information can be transmitted between two computers via the Internet - IP and TCP / IP - widely published. This event paved the way for the development rushing of the internet era.

The next important event happened in 1976 - UUCP program was born. Now any computer setup UUCP programs and modem can send a file to another computer (also equipped with similar devices) through telephone lines. UUCP network is a system of release of the first PC-based phone line. It is a precursor to an independent network in the future.

The development of UUCP networks led to the birth of the Usenet system, also known as "electronic newspaper". UUCP is not only allowed users can send a message to all other networked computer system and at the same time gave them the ability to choose the information on one topic that interests you. Currently, Usenet and email are still the basic services most people use the internet.

Subsequently networks growing at breakneck speed, and 1979 began the process of connecting them together. With the cooperation of independent networks - CSnet (Computer Science Research Network), Binet (Because It's Time Network), FidoNet, NSENET (National Science Foundation Network), the skeleton of the internet is formed. And this process finished completely in 1990. An official letter was issued, according to which almost anyone wishing to also allow internet connection.

The next important event in the history of internet development occurred in 1990, when the Federal Commission on Information Systems cancellation provisions which want to join the network must have the recommendation of a body certain state. From now on, anyone can use the internet without having to apply any of the papers. Internet began to conquer the world, draw all humanity into virtual space.

One of the last and most important event is the birth of the World Wide Web (WWW) is based on hypertext technology. 03/1989, Tim Berners-Lee [4] published a global hypertext project allows physicists can work together on a network. In 1991, the laboratory of experimental physics in Europe (CERN) in Switzerland announced to the world for the advent of the WWW. With the help of hypertext language (Hypertext Markup Language - HTML), a virtual space contains information, documents, audio, video image appears. On the internet, connect the fiber cables computers together; longer on the web, connections are hypertext links. Internet exists is due to the link between the computer programs. World Wide Web - WWW can not exist without the base network (the network of transmission lines and the affiliate program), the global network but also makes the network more useful basis, by people really interested in the information, not the computer and data transmission cable.

Internet beginning of the era of e-business. If, like new, only used for communications, internet today, it has become a tool in the business. If in 1997, the e-commerce transactions with a total value of $ 8 billion, in 2000, the figure was $ 1,300 billion.

2.2 Some advantages and disadvantages of the Internet.

The Internet’s benefits are undeniable. As a result, our life becomes much more comfortable. First of all, the Internet provides faster communication channel like e-mail, instant messaging, file transfer and file sharing. With this, users will be able to communicate effectively and save time and effort. Moreover, people can update latest news and online references whenever they want because most of the newspapers today are online, as long as their laptops or mobile phones can access the Internet. Entertainment is also a positive effect brought by the Internet. After hard working or schooling, people can use the Internet to relax with playing computer games, listening to music, even chatting with friends all over the world through Facebook, Skype….

However, there are some obstacles which always make everyone worries. While in the past viruses were often spread by opening an infected e-mail, these days simply surfing the Internet is enough to be vulnerable to getting a virus. In addition, hackers are also the fear of users because they always want to steal private information and credit card number for illegal purposes. Finally, people are sharing plenty of their information on social networks such as Facebook, Twitter and saving data inside their mobile phones. This leads to their own personal information can be sold to several companies for marketing activity.

2.3 Development trends of the Internet in the future.

What the Internet in the future is an exciting question. We are sure that the Global network will become faster and more important role in our life. However, new softwares created everyday will replace old products. As a result, users can enjoy a lot of wonderful things from these innovations. For instance, HTML 5 is the new version of HTML,which was upgraded with many new features and it is the technology of the future. HTML5 is a language structure and presenting content for the World Wide Web and will be the core technology of the Internet in the near future, first proposed by Opera Software. This is the 5th version of the HTML language and currently being developed by the World Wide Web Consortium and WHATWG. Target core language design is supporting for the latest multimedia while keeping people and equipment, computer programs such as web browsers, screen readers, etc... HTML5 will still retain the basic features of HTML4 and adds outstanding specifications of XHTML, DOM, particularly JavaScript. On the other hand, HTML5 is provided free of charge for both developers and users. Furthermore, HTML5 will have an advantage about the popularity entering the mobile environment. For example: Flash is a plug-in while HTML5 is directly rendered from the browser so popularity will certainly much higher than Flash!
