1. GPIO Connector: The GPIO Connector on the Pi is a male header which can be used to interface hardware with the Pi. It has 8 and above GPIO(General Purpose Input Output) pins on which led's etc can be connected. These pins are very sensitive and can only handle small currents.
2. USB Ports: The Pi has 2 to 4 USB ports. They work the same way as any other USB port and can be used to connect Mouse, Keyboard, Wifi dongle, Flash Drive etc.
3. HDMI Port: The HDMI port is used to connect the Pi to a display. It is pretty straightforward but may require some configuration. I will delve into that later on.
4. Ethernet Port: The ethernet port is used to connect the Pi to an internet connection. Its just plug and play. Although Wifi is much more convenient hence i will tell you about installing that as well.
5. Display Port: The display port is a ribbon connector port used to connect the Pi to its dedicated LCD display which is available in the market.
6. Camera Port: This camera port is also a ribbon connector port used to connect the PI camera to the Pi. I will show you how to do that later on.
7. Composite Video Jack: this is used to connect the Pi to a composite video display. It requires some configuration to it started.
8. Power Jack : The Pi is powered using a Micro USB Adapter of 5V with minimum current capacity of 500 mA but its better to use a good quality mobile charger rated at 1 A for smooth performance.
