Product name structure

Hi,

I'm looking for 'product name structure' of Dell EMC Networking products.

There are product series like the below.

"Z"-series

"S"-series

"C"-series

"N"-series

"X"-series

"E"-series

Question>

I'd like know the meaning and fullname of "Z, S, C, N, X, E" to distinguish each product.

e.g. C2960 -> Catalyst

Question>

I'd like know the meaning of alphabet at the end of product name the below.

"FB" of S4248FB

"FBL" of S4248FBL

"FE" of S4148FE
