A blog is a journal type web page, in which articles appear in reverse chronological order - the newest article appears first, followed by older articles. The name of the blog comes from the abbreviation "web log".

Publishing articles on the blog is as easy as editing an email. Articles, comments, descriptions, images or videos can be published.

Visitors to the blog also have the opportunity to leave comments related to the blog articles, thus creating a communication environment between the blog author and his audience (friends and other visitors).

Thanks to this interactive way of communication, as well as the ease with which you can publish on the Internet, the blog has become the most popular way to express yourself on the Internet and the most widespread type of web page.

Most blogs are personal diaries, with general topic. However, there are blogs focused on a particular topic, such as: fashion, music, politics, photography, It, GSM, etc.
