How big is the Internet?

Every minute over 400 hours of video footage
is uploaded to YouTube. In total, nearly 3.7 billion humans use the
internet and its services on earth. But… how big is the internet in fact? [INTRO] Even though YouTube has over 70,000 video views per second and keeps an unbelievably
enormous number of videos, it’s only a single page out of the entire web. Whereby the internet can be divided into multiple
parts. First, there’s the visible web, the so-called
World Wide Web. It includes pages like the all-known Google,
Wikipedia, YouTube, Twitter et cetera, which we use every day. This division of the internet is often also
named “Surface Web”, as it represents the surface of a digital ocean, which can
be browsed by search engines like Google. Approximately 1.2 billion websites are accessible
for everyone within the World Wide Web… and every second, there are new ones to be
added. Underneath, the “Deep Web” is located,
which consists of websites undiscoverable by search engines. Examples of Deep Web content are databases,
some forums, secured accesses like e-mail or online banking accounts as well as similar
related things. One is divided, how big the Deep Web is compared
to the Surface Web. A study by the company BrightPlanet implies
that the invisible web is 400 to 550 times greater than the visible web. Among all that data you can find information
from the NASA and the National Climate Data Center, as well as digitalized books from
libraries. Though, the estimation by BrightPlanet can’t
be easily verified. Thereby, the Deep Web could be only a tenth
as big. Let’s continue with the Dark Web. This part of the internet can only be accessed
by using the so-called Tor Browser. It reached prominence because of criminal
activities like drug dealing, weapon selling, child pornography, contract killings and many
more. On the other hand, however, activists in dictatorships
and countries with limited free speech rights utilize the Dark Web to communicate, as it
isn’t and can’t be surveilled by any government – apart from the US administration. This is because the USA themselves built the
Dark Web and the Tor network for military use cases. Finally, let’s look at the actual size of
the internet. There are several different estimates, but
one says that the internet doubles in size every two years. At the time of writing this video, this value
lays at 11.1 zettabytes. What exactly are zettabytes? 11 zettabytes are 11 sextillion bytes – or
an 11 with 21 zeroes. If you printed every single byte represented
by a letter, you would have a resulting paper area which is 11 billion square kilometers
(or about 4.25 billion square miles) in size. Thereby, it would cover the entire globe with
22 layers of paper. Until 2020 this data quantity is expected
to reach 40 zettabytes, which would result in nearly 88 layers of paper full of letters. Then, we would have a completely different
issue than the climate change. And in 2030 we arrive at 1 yottabyte of data. With this amount of disk space, we could capture
the whole life of every human on earth from birth to death on video. Okay, actually, what exactly is Facebook doing
differently? Or, you could convert the number of bytes
into water molecules and enjoy drinking a small glass of water, since this exact amount
is contained in 240 grams (or 8.47 ounces) of water. In the description, I am going to link some
further websites which demonstrate how large the internet is. And apart from that: thanks for watching,
don’t forget to like and comment this video and as always, I hope to see you next time.
