What is an uplink port?
How do i know if my switch has one?
Can i turn it into a down link port?
What i take an uplink port to be is port 1, so that i can
plug directly into it another switch/hub.
Port 2-24 are downlink ports, so that i can receive data
from pc's, am i correct to assume this?
Thanks for anyone who takes time out to reply to what is
probably a silly question

Uplink ports are ports on a hub or switch designed for connecting to
another hub or switch to allow you to daisy-chain them. Note that only
one end of a switch-switch connection needs to be in an uplink port.
Some hubs/switches have a small button that allows a port to be
designated uplink or normal, others can autosense, still others have
two port sockets, one for normal use and one for uplink use, of which
only one of the two can be used at a time. And some don't have them at
all. If your equipment has them, it's usually fairly clearly marked,
usually as uplink, sometimes MDI-X or just X.
If a hub/switch has an uplink port, they're commonly either on port 1,
or the last port on the hub or switch.
From a technical point of view, an uplink port is simply one where the
patch cable is automatically cross-over'ed internally by the hub or
switch. It enables you to connect two hubs/switches together with a
straight-forward plain patch cable. On hubs/switches without an uplink
port, you must use a crossover cable to daisy-chain hubs and switches.
