Web is mostly recognized as World Wide Web (WWW). The Internet subset that contains number of pages and can be accessible through web application is called web. Integrating the number of web forming a internet as a same way integrating a number of web pages forms a complete website. So we can say web is somehow a building block of internet. Web is mainly of 2 types a) Surface Web and b) Deep Web.
a) Surface Web
Surface Web can also be known as World Wide Web. In above figure the whole iceberg refers the web. The area above the water is called Surface Web. All the information or data that can be searched or view from normal web browser like Chrome, Firefox, Safari, etc. are Surface Web. Surface Web covers only 4% of the total web and remaining 96% is occupied by Deep Web. All the activities you do in surface web are stored in their server and if they want they can track you back.
b) Deep Web
Deep Web means the the web which cannot be searched by the normal browser. In the above figure the part below the water is considered as Deep Web. Deep Web covers the 96% of the total web. Which means the things you are searching in daily life via normal web browsers is only 4% of the whole web. This shows the wide range or the area of web. Deep Web is mostly used for hiding the information from the world. All the data of Deep Web is encrypted so it becomes very difficult for someone to track it down so the user remain anonymous. This type of web is mostly used by Bank for private transaction, Police to share or receive secret information. To access the Deep Web you have to download and use the TOR(The Onion Router) browser. The link which is used to access the Dark Web cannot be access in normal Web Browsers. There is another sub part of Deep Web which is called Dark Web.
Dark Web
Dark Web is the bottom part of web. All the contents of the dark web cannot be viewed or searched in normal web browsers so it can be only access through the TOR browser only. The dark web can only be access through the link which consist .onion at last like .com in surface web. So all the information you put on the dark web are not indexed by the Web Browsers. It is very difficult to analyze all the activities here because all the users and the services provided are anonymous. In surface web the location of computer or the users can be easily detect but it is nearly impossible to detect the users in dark web. Due to its anonymity it is the popular place for the criminal activities. Most of the criminal activities like child trafficking, drug dealing, weapon buying and selling, etc are done through the dark web. It also consist of illegal version of E BAY which is known as Silk Road where all the illegal goods and services are purchased. It also contains some hidden information of some companies. Through the dark web hackers can easily make the pirated website and if some user unknowingly click that site hackers can hack your whole computer so that your personal information can get into the wrong people hand. So the best idea to stay from this time of link and site is that never ever try to use dark web.
