Connecting servos?

I used to go on to the automatization lessons in my towns art and technology center, and there we were connecting servos directly into arduinos +5v pin. My questions is; is it possible to do so with different types of servos

P.s. We were using towerPro sg90 servos

You can in theory, but many types of servos will draw too much power from the Arduino and cause your program to malfunction in strange ways. It is better practice to connect them to an external power supply.
