In the output: the term tty stands for teletype. In the olden days of computing, a terminal was just a keyboard with an attached printer, so you read everything off the teletype. and PTS stands for Stands for pseudo terminal slave which means a user had opened a terminal from x-window. The number of terminals will be opened it will be listed as pts/0,pts/1 and so on..

The difference between TTY and PTS is the type of connection to the computer. TTY ports are direct connections to the computer such as a keyboard/mouse or a serial connection to the device. PTS connections are SSH connections or telnet connections. All of these connections can connect to a shell which will allow you to issue commands to the computer.
