public class Activity
extends LayeredNetworkElement
                    
```
An Activity represents an individual processing step or service operation within a Task in a layered queueing network.
Activities are the fundamental units of work that define what processing happens when a request is served by a task. They encapsulate:
- Resource demands (CPU time, I/O operations, etc.)
- Service calls to other tasks (synchronous and asynchronous)
- Processing logic and execution flow
- Binding relationships with entries that trigger them
Key characteristics:
- Host demand: The computational resources required on the processor
- Service calls: Requests made to other tasks during execution
- Call ordering: Whether calls are made deterministically or stochastically
- Entry binding: Which entry point triggers this activity
- Reply activity: Whether this activity sends replies back to callers
Activities can make both synchronous calls (blocking until response) and asynchronous calls (fire-and-forget) to other task entries. They are connected through ActivityPrecedence relationships to form complex execution graphs.
