Description

A processor is generally a unit able to execute operations. A Logical Processor is the term used to represent the fact that today:

A processor can be virtual (vmware, MS hyper-v).
A physical CPU/Processor can have multiple cores/processors.
A hyper-threading capable core is divided into two logical processing units.

The term Logical Processor describes what we see from a software perspective as the processing unit.
