1. Console: The console is a direct access to an operating system when it is connected through VGA, HDMI, DVI etc.

2. Remote: The 2nd type of access is remote where you connect to your operating system remotely over the network. e.g. putty. But if you have windows 10 or newer version yo do not need putty you can directly connect from the command prompt.
