Controlling a servo is one of the most common tasks for this shield.
Each pin consists of three vertical headers: S (Signal): Connected to the Arduino digital pin. V (VCC): Positive power supply (usually 5V). G (GND): Ground (0V).
The URF (sometimes labelled ) header is intended for ultrasonic range finders. It brings out two analog/digital pins (you can choose which to use) together with power and ground. This makes it easy to connect popular modules like the HC‑SR04 without any extra wiring. arduino sensor shield v5 0 manual

is a popular expansion board designed to simplify the connection of multiple sensors, servos, and modules to an Arduino Uno or Mega. It eliminates the need for messy breadboard wiring by providing dedicated 3-pin headers for every digital and analog pin. Controlling a servo is one of the most

Dedicated header for serial communication modules. G (GND): Ground (0V)
You didn't need to wrestle a ground wire into a breadboard. The shield provided organized power rails for every pin.
Cause: D0 and D1 are also the serial RX/TX lines. If you upload a sketch or open the Serial Monitor while a device is connected to these pins, the device may interfere.
