Using Subdomains Vs Creating Muti-Site
Subdomain is a secondary domain within your website. your subdomain will look like subdomain.mysite.com. By using a subdomain on your site you can create a lot of additional websites within your main site.
Multi-Site is a feature offered by some content management systems where you can create a lot of websites within your main websites. In order to add multi-site functionality on your website, you will have to choose that option while installing content management system (I am talking about wordpress, I do not know about multi-site options on other content management systems). When you create multisite, your website will look like mysite.com/mutisite1, mysite.com/multisite2 etc.
