Web parts are one of the basic user interface components in SharePoint that enable developers to create visual components which can be configured by end users. So Web parts are reusable components that can be deployed and added to many different SharePoint site pages.
In SharePoint 2010 we can create two kind of custom Web Parts :
1. Visual Web Part - While creating a Visual web part you will have a design interface available with you, where you can simply drag and drop checkboxes, labels or your own custom controls to make up the web part UI. To add the business logic, a code behind file is also attached to the web part.
2. Standard ASP.NET Web Parts - Here you will have to build your user interface and logic in a class file. Unlike, visual web part standard asp.net web parts in SharePoint 2010 does not gives you any drag and drop design surface for developing Web Part UI. This type of web part Inherits from Standard ASP.Net web part instead of UserControl or SharePoint web part.
