1961 - Defence Advanced Research Agensy (DARPA) no. The United States Department of Defense began
a project to create an experimental network for the transmission of packages. This network, called ARPANET, was
originally designed to explore methods of ensuring reliable connectivity between different types of computers. Data
transfer protocols were developed in the ARPANET-TCP/IP network. TCP/IP is a set of communication protocols that
define how computers of different types can communicate with each other.
1975 - ARPANET has
evolved from an experimental network into a working network.1983 - The first standard for TCP/IP protocols to be
included in military standards was released, and everyone who worked on the network was required to move to these
new protocols.
1991- ARPANET has ceased to exist, but the Internet, based on the same standards,
continues to grow.
1993 - World Wide Web Service (WWW), based on the HTTP User Data Transfer
Protocol and the special data presentation format - HTML. Documents made in this format are called Web-pages.
The web, or «web», is a set of linked pages with certain information. Each page can contain text, images, video,
audio, and a variety of other objects. But in addition, the web pages have so-called hyperlinks. Each link points to
another page that is on some other computer on the Internet.
Various information resources that are linked by
telecommunications and are based on hypertext data presentation form the World Wide Web (World Wide Web, or WWW ). Hyperlinks link pages that are located on different computers in different
parts of the world. The huge number of computers that are united into one network - it is the Internet, and the
«world wide web» - is a huge number of web pages placed on the computers of the network.Each web page on the
Internet has the address - URL (Uniform Resource Locator) - unique address, name.
On 12 March 1989, Tim
Berners-Lee presented to CERN the project of a unified system for organizing, storing and sharing information that
would solve the problem of sharing knowledge and experience among CERN staff. Berners-Lee proposed to solve the
problem of access to information on different computers by using browser programs that provide access to the
computer-server where hypertext information is stored. After the success of the project, Berners-Lee convinced the
rest of the world to use common standards for Internet communication, using hypertext transfer protocol (HTTP)
standards and the Universal Markup Language (HTML).
The difference between the Internet and the World Wide Web is quite large. While the Internet is a vast network linking millions of computers across the planet to share information, the World Wide Web is only one way to share that information. In addition to ensuring the operation of the World Wide Web, the Internet allows you to use email and various messengers, as well as to transfer files by FTP-protocol
