What is a component?
A reusable modular web site unit that can be used over and over again throughout web sites and web applications that has a specific purpose. A component typically contains a dialog box, html, css, and js files. It also can access dynamic data through web services or servlets.

Sling Resource Processing
AEM is built using Sling, a Web application framework based on REST principles that provides easy development of content-oriented applications. Sling uses a JCR repository, such as Apache Jackrabbit, or in the case of AEM, the CRX Content Repository, as its data store. Sling has been contributed to the Apache Software Foundation - further information can be found at Apache.
Using Sling, the type of content to be rendered is not the first processing consideration. Instead the main consideration is whether the URL resolves to a content object for which a script can then be found to perform the rendering. This provides excellent support for web content authors to build pages which are easily customized to their requirements.
What is OSGI?
OSGi defines an architecture for developing and deploying modular applications and libraries (it is also known as the Dynamic Module System for Java). OSGi containers allow you to break your application into individual modules (are jar files with additional meta information and called bundles in OSGi terminology) and manage the cross-dependencies between them with:
services implemented within the container
a contract between the container and your application
These services and contracts provide an architecture which enables individual elements to dynamically discover each other for collaboration
