Straight through & crossover cable

Hai all,

I have a query with respect to cabling.Straight through cables are used to connect dissimilar devices & crossover to connect similar devices.Is this connection with respect to the port or cable.And What is an uplink port ?I know its used for cascading purpose.Lots of website say MDI is also known as Uplink.Please explain.Thanks.
