Confusing between TCP/IP 4 Layers and 5 Layers?

I'm confusing between those TCP/IP Modules

as we know 4 layers are (Application - Transport - Internet - Link)

and Updated TCP/IP Module have 5 layers (Application - Transport - Internet - Data Link - Physical)

My questions are :

Is Link Layer in original TCP/IP combine between Data Link and physical in updated module? (or there us no exist of physical layer in original one?)

What is data type of each layer (packets - segment - frame ..) for both?

What is the difference between Link in original module and Data Link & Physical in updated module?

Is Link Layer of original module responsible for MAC, Ethernet, Cable and NIC?

What is the exactly difference between both of them?
