Raspberry pi to computer

[RandomCoder]

Is it possible to connect a raspberry pi to a computer, so that if a certain function is triggered on the raspberry pi, i can output results on the computer?

Yes.
A raspberry pi is basically a Linux box. You can put it on a network and communicate with other computers on the network. For example, run a web server on your Windows PC. When it receives a particular request from the Pi it responds in a particular way.
