I do not have any module connected to the arduino and its connected to the computer throught a usb cable. Can any of you help me?

From quick googling it appears this error occurs when you haven't selected correct board and port in your arduino IDE.

 

Go to Tools -> Board -> select Arduino Uno

then Tools -> Port -> select COM port on which the uno is connected.
