A 10BaseT hub with have other media receptacles - BNC, AUI, and on occasion Fiber Optics.

10BaseT cables have RJ45 (telephone type connectors with 8 wire receptacles or pins). They are the 8 plug receptacles on the picture below.

10BaseT Backbone (HUB):

10BaseT hubs are available with 4 to 24 ports, and in stackable versions where you can connect several hubs with up to 128 ports (RJ45 connections) in a stack.

10BaseT can constitute a stand-alone LAN, but most often 10BaseT hubs are used to concentrate workstations for hookup to 10Base5 or 10Base2 bus topologies, or even to Fast Ethernet Switches.
