Web 2.0

Hello viewers welcome to my blog... 

 Introduction: 

21st century is century of technology ,that we know very well. Now when are going to talk about  technology and educational we used many tools for that. Web 2.0 is one of part of technology. So Whatʼs Web 2.0 ?

This document is intended as simple introduction to some free Web 2.0 type tools that can be used by teachers who are interested in using technology in language teaching. The tools presented here are just the tip of the iceberg and this should not be considered in anyway conclusive or even the ʻbest ofʼ Web 2.0 tools. New tools are emerging all the time, many not originally intended for education, but which can be put to good use by students and teachers alike to extent opportunities, enhance learning potential and develop the level of digital literacy that students will need for the 21st century.

So here some explanation about the web 2.0.

• Text based ʻhtmlʼ with some images - The early web was largely driven by text based content formated with a simple programming language called ʻhtmlʼ.

• Broadcast medium - Most web sites were owned or controlled by companies or individuals with web skills. The content was added by web masters and the owner of the website decided what would go on the website. This was a ʻtop downʼ process, readers had no choice and little input into the content that went on the 

site.

• Slow connection speeds - Most visitors were using slow dial up connections which made downloading large files such as video or audio incredibly slow.

• Limited interactivity - If there was any interactivity on websites it was almost completely text based and usually took the form of sending in an email, basic text chat or posting a message on a text based bulletin board.

• Expensive software - Most creative work being done on computers was done using expensive software which was complex to learn and had to be bought on discs and installed on the hard drive.
