Difference between GBIC and Giga Ethernet interface

Hi all,

I will connect 2 switchs catalyst (2950 or 2960) by STP by Giga interface.

For this need, generally, i use GBIC interface and its work fine.

Today, a lot of catalysts are provided with Giga Ethernet interface (RJ45)
like catalyst 2960.

If i use this port (Giga Ethernet interface) to connect the two switchs,
what will be the differences ?

So, i juste need to understand what differences ..
