ICA is a general purpose presentation protocol that provides X Windows- like functionality to the Windows community.
ICA is the physical line protocol used for communication between client and server.
Only the command portion of the packet is always present.
ICA uses virtual channels to add functionality to the protocol.

SpeedScreen 3 provides predictive text entry to provide instant visual feedback on high-latency lines.
SpeedScreen 3 provides instant visual feedback for mouse actions by changing the cursor to indicate that the command has been executed.
SpeedScreen 3 can be configured per application on the server.
SpeedScreen 3 can be enabled or disabled manually from the client.

IMA is both an architecture and a protocol.
IMA traffic uses TCP port 2512.
IMA provides that all configuration information is stored in a central location.
Administrative actions such as shadowing can now be logged and audited.
Farms are made up of zones. Where a farm's spans multiple subnets and locations, a zone is typically one subnet.
The data store is the central database that contains all the farms configuration information.
The data collector is the zone traffic cop that gathers all zone data and forwards it to all other data collectors.
The local host cache is a subset of the data store and speeds performance by caching farm information on the local server. This also allows the server to run for up to 48 hours without being able to contact the data store.

Listener ports accept the connections for the specific protocols and direct them to an idle session.
Idle sessions are the connection point for new users. Once an idle session is used to connect a user, it recycles itself to another idle session.
By default there are two idle sessions.
Client device licensing allows multiple sessions from the same device to consume only one license.
