Wyse basic questions for newbie

Hi,

I am new to Wyse devices (WES7 Standard) and in order to get my head around some of the basic stuff  can you advise on the following?

Hagent - client on devices, does this run on every start up or does it run continuously whilst powered up?

Does this have to be installed and running in order to communicate with the WDM server?

Rapport - is this just the DB or is this what is now called WDM? There are multiple names in documentation I have read.

WDM - Do all clients have to have hagent installed to speak to the server? Can they be configured on the device? ie if the device is not showing in the WDM console can it be pushed out to this device manually if we know the IP?

WCM - Files can be pulled down from WDM server on each start up or stored locally. How can we check this on the device?

Is there a guide anywhere with the boot process in the order these processes take place, ie dhcp to get ip address, dns, hagent, wdm etc

Thanks in advance.
