 ICT - A S A SOURCE OF INFORMATION IN THE FIELD OF EDUCATION:

    ICT Full Form

ICT is referred to as Information and Communication Technology that is a combination of service industries and manufacturing industries that plays a vital role in transmitting and capturing electronic information.

ICT is an umbrella term that includes any communication device, encompassing radio, television, cell phones, computer and network hardware, satellite systems and so on, as well as the various services and appliances with them such as video conferencing and distance learning.

When talking about ICT as a source of information in the field of education one would immediately think of Google. 

    Gone are those days when if you would need to look up for some word in a foreign language you would search through a heavy Big dictionary, specifically Oxford one. If you need any article from past for your reference you would have to walk down to the library and search for the specific book or news paper for the content that you are looking for which was a tedious and time consuming process.

    If you wanted to refer a specific book you had to search with all publication houses, write a letter to them and sometimes to the author itself asking for the copy...all this trouble has been wiped out to a great extent or completely because of ICT that is Information and communication technology.

    Specially in the field of education when a teacher or a student wants to look up some information or a word, information is available at finger tips within no time , provided you have an internet connection going for you. We normally use our cellular data or wifi for looking up any information on the net.

    Websites like Wikipedia , Quora , Google search engine are very populary used for getting information.

    While for information we also use You tube Channel which has a huge source of information.

There are thousands of people from all the corners of the world be it rural or urban area, from south pole to North Pole , make thousands of informational videos and post it on You tube. This information is available to us 24/7 at our finger tips. This is really great tool for learning , whether you need a quick receipe or a quick explaination of a lesson or topic.

Also There are various Apps and Platforms available to share information through chat, videos , conference call or online lectures. eg. Zoom, Google meet, Google classroom, watsapp , Hangout, Telegram etc.

                                                  

           

Examples of search engines:-

Due to the advancement of technology, there is much software which is used for search. Some software works in a good manner like without hanging, without taking time but some are just in the market to spread the virus. Following are the software that impresses the world by their activities.

• Google search: – Nowadays, Google search is like a vogue. This engine box is so popular that when someone is unable to find any information then only one phrase comes first in the mind that is ‘Google it ‘.It is a secure engine and gives results very accurately.
• Microsoft Bing: – This is also very famous and used by many people. Microsoft Bing does an excellent job of finding the information.
• Yahoo Search engine: – This is not so popular like the upper ones but yahoo also does better work to give the best relevant results to the user.

There is the number of search engines that give different results and this depends on algorithms. Because every site has different data and has a different approach to find the information that user demand and also tries to correlates that information with the ambition of 100% best. So, this can happen that every search engine gives different information but that information always co-relates with each other. Each search engine has its unique algorithms. So, it is not necessary that the top ranking of Google is the same as the yahoo’s top-ranking or vice-versa.

How to use a search engine?

It is accessed through the browser of user’s laptop, mobile phones or any other devices. On the page of the internet, there is a text bar on the top of the page through which one can find any type of information and numbers of results will come that relates to your content. This service required internet service. Every search uses the different mathematical formula to generate the search results.

What happens when a search is performed?

When a search query is entered into the search engine, then it shows all the relevant results that are identified from the index and the algorithm that is used to hieratically rank the pages into the results. It is a very quick process. The algorithm used to rank the relevant results from the different search engines.

In addition to search queries search engine use the relevant pages to give the relevant results:

1. Previous research engine: – In this, the search engine will result in different research for a query that depends on the previous research.
2. Location: – Some search queries are location dependant. For instance, a food court near me.
3. Language detected: – Some search engine will give results in the language of the user.
4. Device: –  Different kinds of results is finding according to the device.

    Behind the search screen how a search engine works?

The search engine contains the million and billions of pages and some search engines do not only show the result but also gives the better output based upon the search of the user. This is done by the various algorithms.

• When a keyword is entered to the search box, on that time algorithms Fitch the data which already contained in it.
• After that, there is huge data related to the user’s search .then via algorithms data is filtered according to the original content.
• Next, the filtered data is again shuffled and search engine showed the best 10 results on the screen. It is a very fast process which is done in nanoseconds.
• The search engine only sees the text on web pages and use the underlying HTML structure to determine the relevance.

CONCLUSION :

ICT or information and communication Technology is a term that refers to all Information technologies including artificial intelligence, machine learning and robotics. That includes technologies such as cell phones, television, software, hardware, network, internet and video conferences. It helps to connect people with increased speed and low cost. ICT makes life very easy for a learner whether its a student or a teacher, making information available in seconds at fingertips.
