A turntable plays various size records. It outputs audio via RCA cables (the red and white audio cables). These cables carry an analogue signal that must be converted to a digital signal when recording to a computer. A USB adaptor connects to a USB port and acts like the computer's sound card. Many USB adaptors can accept RCA inputs that the adaptor translates into a digital signal for use with the computer.
