Connectors and Components of the Raspberry Pi

Obtain a photo or a graphic representation of the Raspberry Pi and record the following connectors and components in a graphing application.
  1. Where is the keyboard and mouse port (USB)?
  2. Where is the network connection (Ethernet / RJ45)?
  3. Where is the connection for a screen (HDMI and RCA video)?
  4. Where is the connection for the loudspeaker (jack)?
  5. Where is the connection for the power supply (Micro-USB)?
  6. Where is the slot for the SD memory card?
  7. Where is the extension slot (GPIO)?
  8. Where is the system-on-chip (SoC) of the Raspberry Pi?

The Raspberry Pi 3 B is barely distinguishable from the Raspberry Pi 2 B at first glance. Form factor and position of the connections are identical. However, the status LEDs have moved from top left to bottom left. At the top left is the antenna for WLAN and Bluetooth.
External connections of a Raspberry Pi
A Raspberry Pi has different connectors that are led out of the case, so they are outside the case. The task is to name them and define what you can do with them.
task
  1. Determine which external connector (outside the case) has a Raspberry Pi.
  2. What can you connect to these external connections?
Solution: External connections of the Raspberry Pi Model B
