In the traditional Ethernet 10BASE-5, what do "10", "BASE" and "5" mean respectively?

Short for twisted pair Ethernet.

"10" means that the propagation rate is10 Mbps;

"Base" stands for "baseband transmission";

"T" stands for twisted pair.

It is suitable for baseband local area network (LAN) calibration through Ethernet, using twisted-pair cable, and in star topology.

The speed is 10 megabits per second. All nodes are connected to a central hub called a multi-port repeater.

Medium.
