The 3550 is a layer 3 switch. It has the capability of routing as well as switching, though it requires an EMI image to utilize routing protocols such as OSPF or EIGRP.
In addition, it has 2 GB ports.
The 3524 is just a layer 2 switch. no routing capabilities.
Both are older switches and have been replaced, but support is still available for the 3550 (we have 7 of them in our network). Not sure about the 3524, but I believe support for that will cease sooner, if it hasn't already, as it was the higher end version of the 2924.
Confusion all over the place :(
