Topic 4 !! - Search Engines & Online Databases -

Greetings to all! << Ok, you must feel annoyed by now, right? I'll try to change it later.



Move on with the new topic, Topic 4! We learnt about search engines.

Search Engines is a web tool that allows users to enter keywords and find information on websites contained in its database, in a simple way, your daily routine of typing in keyword(s) at this white square with 'Google' or 'Yahoo' or whatever you usually used to search for anything you want.

                

In each search engines, they have their own databases. The more databases a search engine have, the more faster and a lot of choices based on the keywords that you can choose.

        

There are also specific search engines that are designed to search for related topic/keywords.
I'm very sure you know the most common one, Google Scholar!

well, I also just know ONLY this! Haha, poor me! 

I learnt more new specialized search engines, such as

Pipl.com

Artcyclopedia.com

There is also 'Meta Search Engines' , if you want to search something from many search engines.
We have;

Metacrawler.com

Dogpile.com

Savvysearch.com

Of course, there a lot more search engines you can found. I had a lot of fun looking through this new sites I encountered! You can try it too!

The most interesting part that I learnt from this topic was the Deep Web and Dark Web. All the things we went through from the top of this post is just a Surface Web, where it is very basic and easily reachable.

But for Deep Web and Dark Web, it is where all important and confidential thingy that not everyone can look through it. Usually, only hackers or those specialized in this kind of network know how to go into this kind of web. (Don't do it if you don't know!!)
It also called as 'Onion Sites'. I searched for the meaning behind the naming,

'Such addresses are not actual DNS names, and the .onion TLD is not in the Internet DNS root, but with the appropriate proxy software installed, Internet programs such as web browsers can access sites with .onion addresse by sending the request through the network of Tor servers.'

I also asked my lecturer why is it called that way, and apparently the graph(?) for such sites are shaped like onion, so....'Onion Sites'..... 
well....I searched for some pictures, but nope, I couldn't find any.

This is the last picture before I end this post for today...

TOR sites search engines

So that's it!
That was very interesting and tiring topic! LOL!
See you later!
