Everyone knows what the internet is. With the way the world is today you just can’t live without it. The way that internet use is tied into just about every aspect of life now, it’s hard to imagine what we did for all those years before it came along.
The web is a great thing but it does have its limitations.
Oh, you might not think that it does when you come across something that’s
pretty distasteful, but believe me, there is worse that is available with the
click of a mouse.
Our Internet is divided into three groups that are: Surface
web, Deep web and Mariana Web.
What is Surface Web?
The surface web is that portion of web which we see in daily
life. It can be Browse, Surf and Crawl with regular browser and regular ISP,
because the links on surface web are indexed in every search engines like
Google, Yahoo and Bing.
According to one source, as of June 14, 2015, Google's index
of the surface web contains about 14.5 billion pages.
How is the surface
web created?
Search engines construct a database of pages on the Internet
through the use of programs called Web spiders. The spider receives a copy of
each page and catalogues it, keeping the appropriate information for quick
retrieval at a later date. When a new page is linked, it is eventually
inspected by the spiders and added to the list of reachable pages; the surface
Web.
What is Deep Web?
The “Deep Web”, also referred to as the “Hidden Web” or
“Deepnet”, has plenty to offer those that are bored with the regular internet.
It’s an underground world that operates separate from the regular internet, and
you can find just about anything you want to on there. It’s actually much
larger than the regular internet but there is a reason that it isn’t publicized
very often. Most of the deep web contains harmless information, but it can also
foster serious criminal activity. The deep web is quite large; several times
the size of the surface Web. The phrase "deep web" was coined by Mike
Bergman, founder of Bright Planet.
The content of the deep web is hidden behind HTTP forms, and
includes many very common uses such as web mail, online banking, and services
that users must pay for, and which is protected by a paywall, such as video on
demand, some online magazines and newspapers, and many more.
Content of the deep web can be located and accessed by a
direct URL or IP address, and may require password or other security access
past the public website page.
There is an also term which is most frequently used when we
came across at Deep web, that is, Dark
Web. The dark is the part of deep web but this is not for public and even
not access by government itself. It is only used by Criminals for their evil
deeds. Each and every bad things you can imagine, can be found at dark web,
form online Drugs to Hitman.
A December 2014 study by Gareth Owen from the University of
Portsmouth found that the most commonly hosted type of content on Tor was child
pornography, followed by black markets, while the individual sites with the
highest traffic were dedicated to botnet operations (see attached metric). Many
whistleblowing sites maintain a presence as well as political discussion forums.
Sites associated with Bitcoin, fraud related services and mail order services
are some of the most prolific. To counter the trend of controversial content,
the artist collective Cyber twee held a bake sale on an onion site.
