What is L, E, or S stand for in Switches?

[Nehru Becirovic]

I'm in process of upgrading our WS-C3650-48PD switches to latest IOS-XE image but I noticed when you browse Cisco's site they list 3 different models for this switch and others as well such as:

WS-C3650-48PD-E

WS-C3650-48PD-L

WS-C3650-48PD-S

Does this refer to if the switch is IP or L2 base and if so what does each refer to?  I assume image is universal for all the models but just wanted to double check.

L - LAN Base license (switch is a layer 2)
S - IP Base (some routing protocol)
E - Enterprise License
