Lesson 3

Week 3




Hai everyone😉

Today I will talk about the lesson for week 3 for this subject. Do you know what is search engine?
So in my class, Madam Azidatun taught us about about search engine. It is a web tool that allows users to enter keywords and find information on websites contained in its database. This is some example of search engine:




Now I will share the four parts of search engine:

The first one is Database. It is like a storage where all indexed web pages are stored. Next is Web-crawlers. A web-crawlers ia an automated program or bot "crawls" all over the Web Page collecting information. Besides that, User Interface is also a part of search engine. It is a user-friendly app or site or a page where users may input query and search results are presented. Laztly, the Information Retrieval System. This part of search engine is a system used to match the user's query to indexed webpage found in database. The results presented in rank according to the mostrelevance answer.

Other than that, I also learned about Specialized Search Engine and Meta Search Engine.Specialized Search Engine have many benefit and have many category for example for students like Google Scholar and Academia.edu. And you also can find people thorugh pipl.com. Meanwhile, if you use Meta Search Engine, it gives results based on a combination of results from other search engine databases. It specializes in concatenating databases from a variety of search engines and linking search results to relevant sources. For example, Metacrawler and Dogpile.

After that, I also learned about Computer Mediated Communication (CMC) and ESL. CMC is any term of communication or interaction between two or more people with seperate computer through network connection. There are two types of CMC which are Asychronous CMC and Synchronous CMC. Asynchronous CMC messages are not exchanged and replied are not immediately. While Sychronous CMC is on the other hand, the messages can be exchanged and replied to immediately. It also allows the direct communication.

Lastly, the Collaborative Learning. This type of learning allows a group work to be done together without being in the same location or using the same computer. It is a very good way for the students exspecially. It can be used by students to do their group work together and exchange their idea easily.

That is all for now. See you again😊
