When you’re connecting to a Cisco router or switch, you’re going to use one of two methods:
Physically connecting a laptop/PC to the switch or router
Connecting from a remote location via Telnet or SSH
Console lines are used for the 1st case i.e. when you connect physically.
The console port is mainly used for local system access using a console terminal.
VTY lines are used for the 2nd case i.e. when you connect remotely.

Abbreviated as VTY, virtual teletype is a command line interface that enables users to connect to the daemon using the Telnet protocol. To connect to a VTY users must setup and use a VTY password.
In multitasking computer operating systems, a daemon is a computer program that runs as a background process, rather than being under the direct control of an interactive user.
