Growth of Internet user’s

Md. Abu Kausar


The World Wide Web (WWW) has changed the computer and communications worlds like nothing before. The basic objective of the WWW is to create a widespread information space for communication and sharing of information among different users around the whole world. No other information system has taken such a meaningful place in our life in short span of time than is worldwide largest data network known as World Wide Web.

The WWW is becoming a common repository of text, document, images and music etc. in a large scale never seen before. The success of web is based on the idea of a standard user interface which is constantly the same no matter what the platform is used to run the interface. As a result, the user is protected from details of communication protocols, location of machine, and operating systems. Further, any user can build its own web pages and make them point to any other web documents without any restrictions. This is a key feature because it turns the Web into a new publishing medium which is accessible to everyone. As an immediate result, any user can push his or her personal plan with little effort and almost at no cost. Moreover, people use computers and perform different type of task daily on computers which cause a revolution. For example, online shopping and home banking through internet is becoming very popular and have generated several hundred million dollars in revenues.

Collecting the information from the Web and identifying related information which matches a particular query is studied in the field of Information Retrieval (IR). Nowadays, it is not possible to imagine the Web without the use of search engines. The search engines join several complicated retrieval techniques and become essential tools for navigating the Web.

Despite too much achievement, the WWW has initiated latest problems of its own. Finding valuable information from the web is a very complex and tedious task. For example, to satisfy his information need, the user may navigate the space of Web links searching for information of interest. However, since the hyperlink is very huge and almost unidentified, such a navigation job is generally ineffective. For new users, the problem becomes harder, which might entirely irritate all their efforts. The main difficulty is the absence of a well-defined underlying data model for the Web, which shows that information definition and structure are regularly of low quality. These complexities have attracted improved interest in Information Retrieval and its techniques as promising resolutions. As a result the Information Retrieval has achieved a place with other technologies.


The World Wide Web has growing at very fast rate. Some studies have been done to approximate the Web size and although they all report slightly different numbers most agree that over millions of web pages are available on Internet. There is no any method or criteria through which we can measure the exact size of World Wide Web, but the approximate size of web can be measured through the indexes maintained by some popular search engines.
The most popular search engine known as Google had 26 million web pages indexed in 1998 and now it indexes around 67 billion web pages as shown in Figure 1.

Other popular search engine Bing indexes around 16 billion web pages as shown in Figure 2. The two most popular search engines, Google and Bing indexes more than 46 billion web pages as shown in Figure 3. Other two search engine Yahoo and Ask has stopped showing the total number of results, from the above figure of web it cannot be concluded that they represent the accurate size of Web because modern search engines can only crawl visible Web which is a little part of the entire Web. Any search engine cannot indexes more than 20 to 30% of web documents. A huge portion of secret data and other valuable information is not accessible even through these well-known search engines. It is presumed that the size of web which is not visible also called deep Web is many times larger than the size of the accessible Web which is known as surface Web. Digital books, library catalogues, journals, research reports, patents are some examples of web documents that generally not allowed be crawling and indexing by search engines. Many well-known search engines such as Google, Bing and many others are opposing to find a solution for web which is not indexed by traditional search engine.

Now a day it has become an important part of human life to use Internet to gain access the information from WWW. The current population of the world is about 7.349 billion out of which 3.34 billion people (45.44%) use Internet (see Figure 4). From .36 billion in 2000, the amount of Internet users has increased to 3.34 billion in 2015 i.e., an increase of 928% from 2000 to 2015. In Asia out of 4.03 billion people, 1.611 billion (i.e.48.2%) use Internet, whereas in India out of 1.29 billion, .354 billion (28%) use Internet. Same growth rate is expected in near future too and it is not far away when anyone will start believing that the life is incomplete without Internet. Figure 4 illustrates Internet Users Growth in the World from 1995 to 2015. Beginning in 1990, World Wide Web has grown exponentially in size. As of today, it is estimated that it contains about 56 billion publicly index able web documents spread on thousands of web servers all over the world. It is not easy to search information from such a vast collection of web documents available on WWW.

It is not sure that user will be able to retrieve information even after knowing where to look for information by knowing its URLs as Web is continuously changing.
