The following are the major differences between a VisualForce component and a Lightning component in Salesforce:

1. Visualforce was designed to follow a Page-Centric model whereas Lightning was designed to follow an App-Centric model.

2. In Visualforce page all back-end processing is done with Apex Code on the Server-Side where as in Lightning all backend processing is done using Javascript on the Client-Side Server.

3. Visualforce is built for only Desktop purpose where as Lightning is built for both Desktop and mobile purpose.

4. In Visualforce ,apex code is used to handle server side operation where as in Lightning ,javascript is used to handle client side server and Apex for Server side process.

5. In Visualforce HTML markup language is used and Apex code to handle DML operation where as in Lightning, Lightning Components and Applications come in "Bundles" that store all of the necessary files to run the DML Operation.
