"Our great HOME / How big it is actually the Internet?


The Internet is a busy place and it is expanding by leaps and bounds, say scientists.

By Stephanie Pappas

The Internet is a busy space. Every second, recorded some 6,000 posts in tëitter; more than 40,000 searches on Google; and sent more than 2 million e-mails, according to "Internet Live Stats", an international project site statistics in real time. But these statistics only give some idea of ​​the size of the web.

In September 2014, 1 billion uesbsajte enroll online, a number that fluctuates from minute to minute as some other site and create closed. And under this constant change (but of a kind of quantitative) on the Internet exists and is known by most people is the "Deep Web" that includes things that Google and other search engines do not contain.

Contents of the "Deep Web" can be as harmless as the results of a search an online database, or black market forums, accessible only to those who possess special software Tor. (Even though Tor is not only illegal activities, as used anywhere where people may have reason to go online anonymously).

Combine the constant in the "surface" of the Web, the amount of pallogarritshme the "Deep Web" and it's easy to understand why the estimated size of the Internet is a difficult task. However, analysts say that the web is huge and is getting ever greater.

Guided data

With about 1 billion pages, the Web is home to many more special activities. One of these sites, www.worldwidewebsize.com, which seeks to determine the size using online research by consultant Maurice de Kunder. De Kunder and his colleagues published their methodology in February this year in the journal "Scientometrics". To perform an assessment, the researchers sent a batch of 50 common words that are requested by Google and Bing.

Researchers knew how often were these words appeared in the press in general, allowing them to show the number of pages based on the content of the reference words. The search engines they require pages overlap, so that the method also requires an assessment and reduction of potential overlap.

According to these calculations, until the middle of this month there have been at least 4.66 billion The Internet site. This estimate covers only UEBE searchable, so not "Deep Web". So, as the Internet contains information? There are 3 ways to answer this question, says Martin Hilbert, a professor of communication at the University of California, Davis.

"Warehouses informacinit Internet, communication information from the Internet, and Internet information llogarritja" - said Hilbert for "Live Science". Internet communication capacity can be measured with information he can transfer, or how to transfer the information reaches any given time, he said. In 2014, researchers published a study in the journal "Supercompiuting Fronters and Innovations", and assessed online storage capacity in 10 to power 24 bajts, or 1 million eksabajt.

A byte is a unit of data consisting of 8 bits, and is equivalent to a single character in one of the words you're reading now. A eksabajt is 1 billion billion bytes.

One way to assess the communication capabilities of the Internet, is a measure of traffic moving through it. Under the initiative "Cisco's Visual Networking Index", the Internet is now in "the era of zetabajtit".

A zettabyte equals 1 sekstilion bajts or 1000 eksabajt. By the end of this year, global Internet traffic will reach 1.1 zettabyte per year, according to Cisco, and from 2019-es, global traffic is expected to reach 2 zetabajts year. A zettabyte is equivalent to 36,000 years of video in high definition, which in turn, is equal to the live broadcast on the web all catalogs of Netflix's full 3177 times, wrote in 2011 Tomas Barnet Jr., director of Cisco in a blog post.

That same year, Hilbert and his colleagues published an article in the journal "Science", considering the capacity of internet communication in 3 x 10 in force 12 kilobits per second, a measure of the width of the band's. This is based on hardware capacity, and not how much information is actually being transferred at any moment. In a separate study, an anonymous hacker websites measured size by counting how many were in use IP. IP internet are paths through which data travel, and each computer connected to the network has at least one IP.

According to the hacker assessment, was 1.3 billion IP addresses used on the Internet in 2012. The Internet has changed the landscape of data. In 2000, before the Internet that use massive telecommunications capacity of 2.2 eksabajt mirëngjeshur that, as Hilbert discovered and his colleagues. In 2007, the number was 65. This capacity includes phone networks and telephone tapping, as well as access to the largest reservoir of information that is the Internet. However, data traffic on mobile networks, has already outpacing voice traffic calls in 2007.

Physical Internet

Decades of research and speculative fictions, have led experts to today's computers to create programs like Apple's Siri. If all the bits and bytes seem less abstract, do not worry: In 2015, researchers tried to measure the size of the Internet in physical terms. They estimated that it would cost 2 percent of the Amazon rain forest, to print on paper all the information found on the web (including Deep Web), reported in the "Journal of Interdisciplinary Science Topics".

For this study, researchers made some big assumptions about the amount of text online, considering that a site would require an average of 30 pages of A4 paper. With this assumption, the text on the Internet will require 1:36 x 10 in power of 11 pages to print a copy. (A Washington Post reporter later evaluated that the average length of a site is approximately 6.5 pages printed, calculating that be 305.5 billion page to print across the Internet.)

Of course, typing in the information contained in the letter of the Internet does not involve massive amounts of data that are not texts. According to Cisco research, PB 8000 IP traffic per month is devoted to downloading video in 2015, compared with about 3,000 PB per month for web, e-mail and data transfer. (A petabyte is a million gigabytes, or 2 power 50 bytes).

That said, the company estimated that video traffic accounted for the largest site in the past year to 34,000 PB. Sharing of information ranked second with 14,000 PB. Hilbert and his colleagues estimated the world visualize information in the network. In an article in "Science" in 2011, they estimated that the capacity of analog and digital storage of information in the world was 295 eksabajt and zipped.

To save 295 eksabajt CD-ROM would require a stack of discs ranging from earth to the moon (384,400 kilometers), and then a quarter of the distance from Earth to the Moon, writing studuesit. So a total distance of 480,590 km. By 2007, 94 percent were digital information, which means that digital information in the world itself would exceed the moon if I kept CD-ROM. It will be extended to a length of 451 755 km.

The size of the Internet is a moving target, says Hilbert, but is growing by leaps and bounds. There are only a relief when it comes to this flood of information: Our capacity computing, it is growing even faster than the amount of data stored. While the storage capacity of the world doubled every 3 years, the world's computing capacity doubles every year and a half, nëvizon Hilbert.

In 2011, humanity could accomplish in force 6.4 x 10 18 instructions per second with all its computers - similar to the number of nerve impulses in the brain of a second man. Five years later, computer power is equal to the activity of human brains 8.

Of course, this does not mean that 8 people in a room can exceed the memory of all the world's computers.


In many respects, the artificial intelligence is already exceeds human cognitive capacities (although it is still far from imitating the general aspects of human intelligence). Online, artificial intelligence determines which messages you see on Facebook, what comes after a search in Google and even 80 percent of transactions in the market. The expansion of computing power is the only thing that has made the explosion of data useful online "- says Hilbert. "We are moving from the era of information in an era of knowledge" - he concludes.
