Can someone please clarify these terms?

Hello experts !
Can someone please help me to get these query ?

  1. What is robot ?
  2. What is bot ?
  3. What is Machine ?
  4. What is Robot agent ?
  5. How robot and Machine are linked ?
  6. Can i login same user account on two different pc and create two different machine and robot , and execute same process at same time?

@RobotUi

1 and 2 are same…the user which can execute a process on a machine
Machine is a virtual or physical one where robot runs
Robot agent is the service which runs on the machine to connect it to orchestrator
Via Robot agent machine is linked to orchestrator…robot is the service running on machine
As the user would be busy …the same user cannot run on another machine till it is free

Cheers
