A blog originally came from the word “weblog” or a “web log”. A blog is just another type of website or online journal or diary available for people to read, write and view content online. We should know of one essential attribute that distinguished a blog from websites – the former has written text that can be divided into two types of content, pages and posts
Pages are pretty much similar to what you see on all the websites you visit. These websites are generally coded and designed using HTML, which is a mark-up language that helps technically adept users to make well-designed and fast-loading pages. For bloggers, this would include your about page, your contact page, etc.
A blog is a type of website which has posts (or entries) appearing in reverse chronological order. Blog posts typically appear with the most recent blog post (or entry, post) first, just like a diary or journal.
A blog is a type of website that is usually arranged in chronological order from the most recent ‘post’ (or entry) at the top of the main page to the older entries towards the bottom.
Posts are entries that publish online to your blog on a frequent basis. For example, take a look at Yahoo! India – on the homepage you will see a whole lot of news stories about cricket, movies, news, etc. These are posts. They wouldn’t remain there for a long time. If you would check back in a few hours, you’ll probably find different stories there. Now scroll down to the end of the page, you’ll find the list of “Yahoo! Services and “Yahoo! For Your Business”, these pages rarely change and will always occupy the same position in the current design of the site.
Blogs are generally sorted into categories and tags, which are further sorted by date.
A blog can also be managed by software, sometimes called a CMS (Content Management System), where a lot of the features are automatically created and populated.
