General Purpose Input/Output
These are GPIOs that can be used for basic input and output.
CAN
Controller Area Network(CAN), or as it is commonly known, CAN-bus, is a communication protocol originally designed for automotive applications. It is an asynchronous serial bus network that connects devices, sensors and actuators for control applications. CAN is now standardized in ISO 11898, ISO 16845 and SAE J1939 for automotive, industrial and general embedded communications. CAN-bus is now commonly employed not only in automotive and aerospace applications but also in medical equipment. For more information, please refer the link below:

PCIe
PCI Express (PCIe or PCI-E) is a high-speed, serial computer expansion bus standard that connects a computer with its attached peripherals. PCI Express was developed by Intel Corp. in 2004 to replace the peripheral component interconnect (PCI) and PCI-X expansion buses, along with the accelerated graphics port (AGP) graphics card interface. Today, PCI Express is the primary connection method for most video cards to modern computers. For more information refer the link below:

GND
GND or Ground is simply a reference voltage level(called zero potential or ground potential) against which all other voltages in a system are established and measured.
