Wiki is a collaborative website, which can be edited, updated and deleted by its relevant users, while a Blog is a personal website usually created by an individual to share information. The difference between a wiki and a blog is that users cannot modify original posts made by the blogger.How do you access a blog?
Open a Web browser and navigate to Blogger.com. If you already have a BlogSpot blog, enter your Google account email address and password to access it. If you do not have a blog or Google account, click the "Get Started" link on the right side of the page.
