Repository is a database in which all informatica componets are stored in the form of tables. The reposiitory server controls the repository and maintains the data integrity and Consistency across the repository when multiple users use Informatica. Powercenter Server/Infa Server is responsible for execution of the components (sessions) stored in the repository.

hi,
Repository is nothing but a set of tables created in a DB.it stores all metadata of the infa objects.
Repository server is one which communicates with the repository i.e DB. all the metadata is retrived from the DB through Rep server.All the client tools communicate with the DB through Rep server.
Infa server is one which is responsible for running the WF, tasks etc... Infa server also communicates with the DB through Rep server.
