Anitagj,
Both terms, 10BaseT and 10BaseTX are interchangeable as they are the same.
While 10BaseTX is not that common, there are a few manuals that refer to it. 10BaseT is the term you are most likely to come across when reading network books or related networking sites.
These cable specifications, plus a few more are analysed in detail under our Networking/Cabling section, so please refer to it if you require more information.
