Integration Server Hosting Adapters

What does it actually mean that integration server hosts adapters ?

Sach,

Starting from the IS6.x all the B2B/ES Adapters sit on the IntegrationServer/Broker when you configure different Adapters like (JDBC,SAP,SIEBEL,JMS,OracleAPPS,EnterpriseOne)…So IS is the backbone of running these in pub/sub model.
