 Sitecore headless development is based on a decoupled architecture where the rendering host is a separate application that handles the presentation logic and the Content Delivery role is a Sitecore instance that handles the content management and delivery. The rendering host communicates with the Content Delivery role using Sitecore headless services, which are APIs that expose Sitecore content and layout data in a JSON format. The rendering host translates a visitor request to a content item in the Sitecore instance. The Sitecore instance using Sitecore headless services returns the content item and the associated presentation details, and so on, to the rendering host. The rendering host renders the content item for the visitor. This way, the rendering host can use any technology or framework that supports HTTP requests and JSON parsing, such as ASP.NET Core, React, Angular, Vue, etc. References:

Versioned layouts allow you to create different layouts for different versions of an item. This means you can have a specific layout for a specific version of the main page that is published for a specific period, such as a company anniversary celebration. You can easily revert to the original layout by switching back to the previous version of the main page. Versioned layouts are stored in the __Renderings field of the item, which is a versioned field. Versioned layouts are enabled by default in Sitecore 10. References:

 The field source is a property that you can set for some field types in a data template, such as Droplink, Droptree, Multilist, Image, File, and so on. The field source specifies the location of the items or media that the user can select from when editing the field. For example, if you have a Droplink field that allows the user to choose a category for an item, you can set the field source to point to a folder that contains the category items.This way, the user will only see the relevant items in the drop-down list. The field source can be a path, a GUID, or a Sitecore query that returns a single item or a list of items. The field source helps you to control the data source and the user interface for the field. References:
