The name Internet comes from the English words " Interconnected Networks ", which means "interconnected networks". Internet is the union of all the networks and computers distributed throughout the world, so it could be defined as a global network in which all the networks that use TCP / IP protocols and that are compatible with each other come together. This was created in the 1960s as a military government project, however, over the years it has evolved to such an extent that it has become indispensable for people.
What is the internet
Table of Contents
The Internet is known as a network of connections through which computers communicate in a decentralized way, this with the help of a series of protocols called TCP / IP. The internet has its beginnings in the 1960s, in an effort by the United States Department of Defense to find an alternative to a possible isolation caused by an atomic war. In 1972, the first public demonstration of the system that was created was carried out, thanks to the collaboration of a group from the University of Utah with three universities in the state of California, this connection was called ARPANET (Advanced Research Projects Agency Network.)
Technical definition of the internet
Technically, the internet can be defined as a group of computer networks that are interconnected, but its operation is not adapted to a single type of computer, to a privileged physical medium, to a specific type of network and to any inclusive connection technology., since it is a dynamic and flexible network, which can be adapted to different contexts technologically speaking. These networks are by themselves a universe of technology, where various branches such as telephony, microprocessors, fiber optics, satellites, electronics, video, television, images, virtual reality, hypertext, etc. converge.
What is WWW / World Wide Web
The WWW / Word wide web, also known as the world computer network, is the system through which hypermedia and hypertext type documents are distributed connected through networks and through which they can be accessed. Through web browsers, a person can find websites that are created by web pages and that, in turn, contain images, texts, videos and other multimedia content, being able to navigate between these pages thanks to so-called hyperlinks, but for this they are it requires a web browser, as is the case with Internet Explorer.
World wide web was created by Tim Berners Lee in collaboration with Robert Cailliau, between 1989 and 1990, during which time they worked for the company CERN at the Swiss headquarters in the city of Geneva, however, it was not made public until 1992.
Internet history
The history of the Internet dates back to the late 1950s, specifically in 1957, when the Soviet satellite Sputnik was launched into space. Being in the middle of the Cold War, the United States was alert to always be at the forefront of technology in military matters. In 1962, a researcher of North American origin named Paul Brian wrote a book about distributed communication networks, in which he described packet-switched networks., said project proposed an alternative to what the Defense Department was looking for, since Brian designed a communication system through computers connected by a decentralized network, so that in this way, if any of the nodes were attacked by the enemy, the rest could stay connected without any problem.
Five years later, the first strategy on packet-switched networks was developed. A detailed investigation and a set of documents that break down a number of internet protocols and similar experiments. This caused Newman, Bolt and Beranek to work hand in hand with the Agency for Advanced Research Projects in 1969, creating and developing different projects.
The objective of all this was to create a network with such an advanced level of technology that the information could reach the recipient regardless of whether a part of it was destroyed, this is known as packet switching, the theory of this process It indicated that all the data that came from a central office had to be divided into small blocks (packets) so that it could be transmitted.
What was the original idea from which the internet emerged
The Internet was the result of an experiment by the United States Department of Defense, in 1969, which materialized in the development of ARPAnet, a network that linked universities and high-tech centers with contractors from that department. Its purpose was to exchange data between scientists and the military. The network was joined by nodes in Europe and the rest of the world, forming what is known as the great world spider web (World Wide Web).
The idea and development of this network dates back to the creation of a project in which a computer network would allow general communication between users of different computers, both for the development of new technologies and for the fusion of the infrastructure of the network that already existed, as well as telecommunication systems. The first data related to social interaction that was carried out through networking are contained in a series of documents that were edited by JCR Licklider, an American computer scientist who worked for the Massachusetts Institute of Technology, in 1962, in these texts analyzes and opens a debate about his own concept, the galactic network.
When the Internet became a means of communication
For many, the web is a mass communication medium, according to experts, this went from being a project for the exchange of scientific and military information between some government and educational agencies, to being the most important means of communication today. This drastic change is believed to have occurred from the World wide web, since thanks to it, access to information was facilitated, in a simple way, to millions of people.
Only 25 years ago it was rare for someone to use a computer, since it was considered only a work tool, with which they elaborated their tasks, however, the younger generations managed to see that in addition to that, it could be used to play just like consoles. Two decades later it is possible to listen to internet radio.
Nowadays when browsing the web you can find a great diversity of information, multimedia files, etc. It is even possible to watch tv on the internet. Currently the platforms have been updated to the point that it is possible that users can make purchases or check their bills through the web, some examples of these searches are bank statements, Banorte online, gas bills, etc.
Stages of the Internet in History
First stage
The origin of the internet as an information network began in the 1960s as a military computer network, being a space closed to only a minority group, where the majority were developers and engineers. This stage was characterized by being in constant analysis and experimentation, it can be said that in this phase the so-called pioneer network was developed, this stage ends in the 90s.
Second stage
The second stage begins in 1994, when the network is made public and people have the possibility of contracting access to this network. However, at this time the service was considerably expensive and at the same time it was somewhat complicated to use, for that reason only the institutions and companies that had systems areas at that time, together with IT professionals, were the ones that could use this service, therefore this phase is defined as the business network.
Third stage
The third phase can be located after the year 2000, thanks to the decrease in costs and the constant technological simplification it was possible that both companies and people in general considered the possibility of joining the activities in the network, all this gave way to the so-called web 2.0 or social web.
Current Stage
Now, the phase of the network that the present occupies can be called the people's web, where more than 4 billion people can access and have the possibility to communicate, which has changed both the communication style, as well as the processes in which business is done and even online games. Likewise, the speed of this is increasingly high, at present there are some websites that allow an internet speed test to be carried out and thus verify the speed with which it works.
Nowadays it is even possible to come across games without internet, that is, they do not require a network connection and yet be able to play them.
Elementary Functions of the Internet
- Communication: people use the network to be in communication and thus be able to be aware of what is happening around them, without having to go to the scene, this happens quickly and effectively. Communication can be used both in research activities, didactics, to communicate intimately or for group discussion. Some examples are email, social media, etc.
- Interaction: An individual can use the web to research collaboratively with others, to learn in support settings, exchange documents, play online games with other users, participate in social groups, make purchases, invest in the stock market, conduct business, among other. In general, interactive spaces are used to carry out virtual and group interactions, some examples of interaction are chats, MUDS, P2P networks, etc.
- Information: This tool is used to search, retrieve and disseminate information. The distribution of information on various types of subject requires a wide range of knowledge and human activities, among the most common examples of information services in networks are the World wide Web, FTP, blogs and although they are almost obsolete, the telnet and Gopher systems.
The Search Engine: the Internet's tool par excellence
The search engine is the system that is responsible for finding the files stored on web servers, thanks to what is known as the web spider. This tool uses the use of keywords, resulting in a list of web pages where there is mention of topics that are associated with the keywords you used in your search.
The first of this was Wandex, created by World Wide Web Wanderer, this was a robot created by Martes Gray in 1993. That same year Aliweb was created, which continues to function today. A year later WebCrawler was created, which differed from its predecessors by allowing the user a search based on words on any website, thus establishing a standard for the rest of the search engines.
As time went by, a large number of search engines appeared, but it was not until 1996 when Sergey Brin and Larry Page began a project that would end with the creation of what is now the most used search engine, Google. With its appearance, the way in which search engines were handled was drastically changed, democratizingsomehow the results that were shown, since they were based on the relevance for users of the content of the web page, that is, priority was given to the results that the person considered most relevant. These search engines can be accessed through so-called web browsers (software that enables access to the web) such as Internet Explorer, Google Chrome, Mozilla Firefox, etc.
Among the most requested searches on the web can include games without internet, multimedia files, such as videos, photos, audios, and also news sites.
