since the invention of the internet

The mạng internet is arguably one of humankind’s most significant inventions. It has connected people around the world in a way that would have seemed impossible đồ sộ earlier generations. It has forever changed the way we work and learn, cửa hàng and ngân hàng, and it has had an almost incalculable impact on the ways people now communicate with one another.

Despite its unconquerable presence in our daily lives, how many of us know the origins of the internet? Who invented the mạng internet, and when? How does it work, and what can we expect from it in the future? If we think about how much it has changed since its creation less phàn nàn a century ago, we might get a better understanding of how much it can evolve again in the coming decades.

When was the mạng internet invented?

When we talk about the invention of the mạng internet, there are actually a few key dates đồ sộ consider.

  • 29 October 1969 is when ARPANET (Advanced Research Projects Agency Network) delivered its first communication between nodes – a message from one computer đồ sộ another for the first time. Known as the first workable prototype of the mạng internet, ARPANET was originally funded by the U.S. Department of Defense, and used packet switching – essentially a way of sending data – đồ sộ enable multiple computers đồ sộ communicate on a single network. That first message was sent from a research lab at UCLA (University of California, Los Angeles) đồ sộ a computer at the Stanford Research Institute (SRI). The plan was for UCLA đồ sộ send the first three letters for “LOGIN” đồ sộ SRI, and for Stanford đồ sộ then send back the final two đồ sộ size the completed word, but the ARPA network crashed after successfully sending just the first two letters.
  • 1 January 1983 is often referred đồ sộ as the birthday of the mạng internet. It’s the date that ARPANET adopted the Transmission Control Protocol and Internet Protocol, or TCP/IP, developed by Robert Kahn and Vint Cerf at DARPA (Defense Advanced Research Projects Agency). Known as the mạng internet protocol suite, TCP/IP is a phối of communications protocols that specify how data is transmitted between multiple networks. Once ARPANET adopted TCP/IP, it effectively enabled multiple computers đồ sộ talk đồ sộ one another using a shared language, and became the blueprint for the trang web of interconnected ‘network of networks’ – the mạng internet – that we’re familiar with today. Other protocols – such as the tệp tin transfer protocol (FTP) also exist – but the mạng internet we’re most familiar with using is built on the mạng internet protocol suite.

  • 1989 marked the invention of the World Wide Web (WWW) as we know and use it today. Not đồ sộ be confused with the mạng internet itself, the World Wide Web is actually the way we’re most familiar with using the mạng internet – through things lượt thích websites and hyperlinks. Created by Tim Berners-Lee, a British scientist working at the European Organization for Nuclear Research (CERN), the World Wide Web was conceived and developed as a means of information-sharing between scientists around the world. On 6 August 1991, Berners-Lee published the world’s first trang web, which was all about the World Wide Web project. And on 30 April 1993, CERN put the World Wide Web into the public tên miền, ensuring that it was available for everyone đồ sộ use and develop. It’s worth noting that prior đồ sộ Berners-Lee’s work, the mạng internet was mainly used only by scientists and governments.

However, while these dates are important, a brief history of the mạng internet actually starts as far back as the 1920s, when research on information theory was taking shape. This work developed into the 1940s, by which time, it was helping scientists đồ sộ make huge gains in telecommunications technology – long before people would even need it for mạng internet access. By the 1950s and 1960s, there were special-purpose computer networks, such as AUTODIN I, a defense command-and-control system.

The creation of ARPANET and its adoption of TCP/IP was, of course, a huge step forward. Soon enough, researchers from Thủ đô New York đồ sộ Norway were using it, and by the 1980s, DARPA was working with the National Science Foundation (NSF) đồ sộ expand its reach đồ sộ the entire scientific and academic communities. The late 1980s also saw the creation of the first commercial mạng internet service providers (ISPs), and by the over of the 1990s, there were thousands of ISPs around the world. And before long, mạng internet use had skyrocketed globally.

How the mạng internet works

It’s a common question – how does the mạng internet work? The answer can seem complicated, but it becomes easier đồ sộ understand when we remember that the mạng internet is essentially just a means of transmitting data and sharing information between devices.

At its core, the mạng internet is a worldwide computer network, one that allows for the interconnection of many networks within it. All of these networks will share commonalities – such as the mạng internet protocol suite, TCP/IP – that allow them đồ sộ speak effectively đồ sộ one another. 

Think about the World Wide Wide you use every day. When you load trang web pages, various standardised protocols are used. For example, the Domain Name System (DNS) protocol converts a tên miền name from the one you’re familiar with (for example, www.amazon.com) into an IP (Internet Protocol) address. It will then use the HyperText Transfer Protocol (HTTP), or Hypertext Transfer Protocol Secure (HTTPS), đồ sộ request from that IP address the contents for a particular page so sánh that it can be displayed for you.

How does mạng internet access work?

Accessing the mạng internet has changed significantly since it first became available đồ sộ the general public.

In the early days, people connected đồ sộ the mạng internet via a dial-up modem that required a phone line. This style of mạng internet connection was much slower phàn nàn the speeds we’re used đồ sộ now, and it wasn’t unheard of for an mạng internet service provider đồ sộ charge a small fortune just for a modem.

Things rapidly evolved, though. Dial-up routing became largely obsolete following the introduction of much-faster broadband routers and wireless (Wi-Fi) connections.

How has the mạng internet grown?

The mạng internet has grown in many unforeseen ways since it first became available đồ sộ the public. From something largely used only by academics and scientists đồ sộ share information and research, the mạng internet took off among the general population alongside a rapid rise in the use of personal computers.

Before long, people were using a trang web browser and tìm kiếm engines đồ sộ find information, rather phàn nàn hauling out encyclopaedias and other physical resources in libraries. E-Mail quickly replaced letters, and people cancelled newspaper subscriptions in favour of getting their news online. Apple, Android and other smartphones soon became the equal of personal computers – and in many cases, have replaced them – and apps have become a part of daily life for most adults in the UK. And social networking on social networking apps lượt thích Facebook and Twitter have at times altered the course of politics around the world. 

And all of this has happened in just 30 years.

The future of the internet

Where the mạng internet goes next is anyone’s guess, but experts anticipate it’ll only get bigger and faster. Augmented reality – where the real world is enhanced by computer-generated elements – is one avenue expected đồ sộ grow, as are virtual reality and artificial intelligence (AI). And given how much the mạng internet has evolved over the past few decades, there are likely đồ sộ be new facets đồ sộ come, ones that we as yet have no knowledge of, in the years ahead, too.
