2. Client-Side Object Model (CSOM)

Client Object Model provides API to access SharePoint objects from a client machine. The core assembly involved is Microsoft.SharePoint.Client.

 You can access & modify SharePoint objects from a remote client machine.

Following are the 3 types of  Client-Side Object Model :

.Net

Silverlight

Mobile

Asynchronous Methods are provided in Client Object Model.

SharePoint provides REST (Representational State Transfer) enabled web services that allow objects to be transferred in JSON format. Client Object Model assemblies in the background uses these web services to communicate with the server.

3. JavaScript Object Model (JSOM)

JSOM provides a comprehensive set of APIs that can be used to perform operations on most SharePoint objects such as Site, Web, List, Content Types, User Permission and so forth.

Following files built for ECMAScript-enabled platform:

SP.js

SP.Core.js

SP.Ribbon.js

SP.Runtime.js

Above files are deployed in the {SharePointRoot}\TEMPLATE\LAYOUTSdirectory. The default master pages of SharePoint define a ScriptManager control, by default  includes references to these .js files. You can also reference manually.

Client Object Model within a custom ASPX page, required to include the FormDigest control by you.
