Is there something special about UART, I2C and SPI pins on AVR/Arduino?

What's the reason for having PORTx and PINx for each port?
One last thing hopefully,    If you read PIND, you will read the state of the pins.    What if DDRD is set to Output? in this case reading PIND is...

What's the reason for having PORTx and PINx for each port?
It's getting alot more clear now, just this last part (hopefully),   If I attach 5 volts to PIND physically on the Arduino board, does it also updated PORTD value or no?...

What's the reason for having PORTx and PINx for each port?
I have read the data sheet but still not so clear on this topic hence asking in this forum;   I understand that PORTx is a register holding the pins value, but PINX...

What's the reason for having PORTx and PINx for each port?
So, If let's say I set DDRx to Output, then set PORTx to all high. Now I want to read the value of the port, i.e do:   if (PORTx == 0b1111){  // }   Do I read...
