Journal 4: Search Engine and Online Database

Do you know what is Search Engine and Online Database? I also did not know what are these two things really are. When Madam Azida asked my classmates and I, all of us could not answered it as most of use never heard these terms before. Actually, Search Engine is a web tool that allows users to enter keywords and find information on websites contained in its database. Google or Yahoo are the examples of Search Engine. It uses software that collects data from Web to include in its database and not forget to mention every search engine has its own database.  There are four parts of a Search Engine included Database, Web-Crawlers, User Interface and Information Retrieval System.

1.

Database- a storage where all indexed webpages are stored.

2.

Web-Crawlers- an automated program or bot

3.

User Interface- a user-friendly app/site/page where users may input query and search results are presented.

4.

Information Retrieval System- a system used to match the user's query to indexed webpages found in database.

In addition, Search Engine was designed to search for a specific area where its database only for specific field like Google Scholar, Education World, Art cyclopedia and Pipl.com .


After the class ended, only then I knew what is Search Engine really is. I had been using it for years but never aware about it not even a second. From my understanding, Search Engine is Google. When me or all of use wanted to get information about something, we use Google or any other software to find it. It where Search Engine plays it role. It actually the one who helped all humankind in this world to find information. Without this Search Engine thing, I believed it hard to get info. I think that all for this time. Wait for my next entry and goodbye everyone :)
