What is 10HALF?
10HALF ("ten-half") is an Ethernet link setting: a speed of 10 Mbps in half-duplex mode.
Today 1 Gbps and 10 Gbps links are common and full-duplex is the norm, but we chose this name to carry the spirit we started with.
10 (Mbps)
Even at low speed, keep moving forward—surely.
HALF (Duplex)
When a collision occurs, detect it and work around it.
