Search Engines & CMC

Search Engines

    Hello everyone! So i'm back with another post. As for today's topic as what you have seen above, you might be familiar with this when I mention Google, Bing or Yahoo. Yes, this is a web tool that allows users to enter keywords and find info on websites that contained its database. Each own search engine has its own databese.

One of the examples of search engine, Bing

     In addition, there are 4 types of search engine that we must know. They are listed below:

1) Database: it is a storage where all indexed webpages are stored

2) Web crawlers/spiders: "crawls" all over to find and compile indexes of webpages

3) User interface: a user-friendly application/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 the database

Specialized search engine

- search engine that is tailored to search for a specific area

- eg: Google Scholar

Meta search engine

- search engine that matches the user's query to multiple search engines

- eg: Metacrawler, Savvysearch

Surface, Deep and Dark Webs

CMC

So, what is CMC actually? CMC stands for Computer Mediated Communication, is any form of communication or interaction between two or more people via separate computers through network connection. For example, like Twitter, Facebook or WhatsApp. It started in the late 1190s with the introduction of Communivatice CALL. In addition, this program is implemented for long distance teaching or learning.

a) Asynchronous CMC

• Communication is not synchronised
• messages are not exchanged or replied to immediately
• eg: emails, internet forums, most social media used this

b) Synchronous CMC

• Communication is rather synchronised
• messages are faster can be exchanged and replied to
• eg: internet chatrooms, video/audio conferencing

c) CMC and Long-distance learning

• allows teacher and learner to interact without being in the same location
• eg: Skype

d) Collaborative learning

• Computer-Supported Collaborative Learning
• can help enhance peer interactions and group works
• eg: Google Docs, Google Drive

e) Authentic Communication

• CMC offers learners easy access and opportunity to communicate with other learners

     Alright, that is all for today's class. I've got to learn many things regarding the search engine itself and other webs that I have never heard before which is totally cool! I can't wait for the next class with the new topic and lectures. Bye for now, untill we meet again. Annyeong!
