Jini is a collection of services (hardware, software, or both)

| 2 |
When "a Service" connects to the network, it sends a small "hello" packets (512 bytes) to announce its existence
|
| 3 |
Jini "Lookup Service" notices this packet and query the service to discover it capabilities, and makes this info available for other devices on the network
|
| 4 |
Then the Service registers with the Lookup Service, it provides a proxy object
|

When a client wants to use a service (for example scanner) it asks the Lookup Service to provide info about available services (the Lookup service provides a copy of the proxy object. The client makes calls to the proxy object that arranges to do the work)
