Amar Kumar 8 years ago

The word blog was derived from the combination of the word web and log. Blogs typically focus on a specific subject (Economy, entertainment news, etc.) and provide users with forums (or a comment area) to talk about each posting. Many people use blogs as they would a personal journal or diary.

a website that contains online personal reflections, comments, and often hyperlinks, videos, and photographs is called blog.
