What is the difference between DX vs DLC? SLC? DLC?

Subject: What is the difference between DX vs DLC? SLC? DLC?
Text: I have a fairly good idea about what 486DX and 486SX mean. DX
refers to a 32 bit pathway and SX to a 16 bit pathway. But, what does "SLC"
or "DLC" refer to? Thank you.

Text: You stated that the differences between a DX and a SX is a 32 bit
pathway versus a 16 bit pathway. This is only partially correct. On 386
computers, a 386SX computer passes data into the microprocessor via 32 bits
and out of the microprocessor via 16 bits. On a 386DX computer, you have
information passed in and out of the microprocessor via a 32 bit pathway. On
486 computers, this is not the case. On a 486, if you have a 486SX, then the
math coprocessor is disabled. On a 486DX, the math coprocessor is enabled.
As for "SLC" and "DLC," "SLC" is like a SX and "DLC" is like a DX, except that
they have low power (3 volt) consumption and they are cache processors. This
information was acquired from IBM.
