What is called as the Virtual Processor in database?

Database server processes are called virtual processors because the way they function is similar to the way that a CPU functions in a computer. Just as a CPU runs multiple operating-system processes to service multiple users, a database server virtual processor runs multiple threads to service multiple SQL client applications. A small number of virtual processors serve a much larger number of client applications or queries.Virtual processors can share processing.Virtual processors save memory and resources.Virtual processors can perform parallel processing.
