Welcome, Colixen!
I guess it depends on what you're hoping to do.
There is a jack for connecting headphones, so you can use that jack to connect a stereo (TRS) audio cable to your computer's LINE IN jack and record audio tracks of yourself playing the CTK-1550.
However, there are no MIDI IN/OUT or USB ports, so you cannot connect to your computer to record MIDI tracks, nor sequence MIDI tracks to your keyboard, nor transfer other types of data (such as song files, rhythm files, or registration files) back and forth between your keyboard and computer.
