 Orca expresses parallelism explicitly through processes.
 Processes in Orca are similar to procedures, but are concurrent instead of serial.
 When a process is forked, it can take parameters that are either passed as a copy of the original data, or passed as a *shared data-object*.
-Processes can then communicate through these shared objects.
+Processes communicate through these shared objects.
 
 Shared data objects in Orca are similar to objects in OOP.
 An object is defined abstractly by a name and a set of interfaces.

 Another key feature of Orca is the ability to express symbolic data structures as shared data objects.
 Because shared data is expressed through data-objects, it is easy to serialize, for instance, operations on a binary tree.

-#### RPC ( and why RPC is shared-memory )

-Tries to make many machines look like a single machine.
-This is hard because of consistency and partitioning.
-The logic of the program is simple, but requiring that the system handle shared memory opens up many opportunities for performance bugs.

 ### Actor / Object model
 
 The actor model has its roots in procedural and object oriented programming.
