1. What's the meaning of PT of PT-Cloud?

IMO, PT stands for Packet Tracer.

2. What's the difference between PT-Cloud and PT-Empty?

There are some pre-installed modules on PT-Cloud, but PT-Empty does not.

Modules on PT-Cloud:

• 2 x PT-CLOUD-NM-1AM
• 4 x PT-CLOUD-NM-1S
• 1 x PT-CLOUD-NM-1CX
• 1 x PT-CLOUD-NM-1CE

Compare PT-Cloud and PT-Empty

My Packet Tracer version is 7.2.1.0218.
