Twisted cable = Crossover cable?

Are they the same? For CAT5 that is.

Thanks

Not necessarily. Twisted cable just means that the wires wind round each
other in a spiral. A crossover cable has the connections reversed at one of
the ends, so that you can, for example, connect two PCs 'back-to-back' via
their network cards.

No - two terms to do with cabling, but different meanings:

Twisted cable means the cable that you see contains several small wires that
are twisted round each other inside the outer casing.

Crossover cable is a way of wiring the end connectors on the cable so that
the cable can be used to connect 2 client devices together. ie. a crossover
cable can be used to connect 1 PC to another PC directly. This is the
opposite as a 'normal', or 'straight' cable, which is used to connect a PC
to a router, hub, switch or other such network device.

The problem that we may not know exactly what you have in mind. So I
guess we may have to go for something like.

Twisted Cable (example)

A -> A
B -> B
C -> F <=- not straight from PIN-C to PIN-C
D -> D
E -> E

Crossover (from one device to other)

PC -> Router (usually straight cable?)
Router -> Printer (usually twisted cable?)
Router -> Modem (usually twisted cable?)
Router -> Hub (twisted or Straight?)

Also, Parallel and even USB cable have 2 different types.

You might find this link of value to you as it shows you how to
identify/make Ethernet cables be they cross-over or straight-through.

As I mentioned that it's my wild guess of what you mean by "crossover"

Unless either (port) end is gigabit in which case a
crossover cable is not needed.

I dunno, but right now I just think that Crossover is pretty much like
straight-cable. And that I learned many years ago when I tried to extend
the parallel cable for my printer, that I found out the "twisted" &
"straight" cable.

Twisted + Straight = normal
Twisted + Twisted = srcewed up
Straight + Straight = if not twisted cable required

Then few years ago it happened to the USB device (Portable Storage without
built-in Memory Card Reader) with USB connecter to connect to an external
Memory Card Reader. After I returned the device to exchange to other, I
found out that it requires a special USB cable between Portable-Storage to
Memory Card Reader to work.

And I just learn from error <bg>
