Even-toed ungulate. The even-toed ungulates (Artiodactyla, from Greek á¼ÏÏÎ¹Î¿Ï (Ã¡rtios), meaning 'even', and Î´Î¬ÎºÏÏÎ»Î¿Ï (dÃ¡ktylos), meaning 'finger/toe') are ungulates (hoofed animals) whose weight is borne equally by the third and fourth toes.

Definition of roundâtrip. : a trip to a place and back usually over the same route.
Round-trip delay time. In telecommunications, the round-trip delay time (RTD) or round-trip time (RTT) is the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgment of that signal to be received. This time delay therefore consists of the propagation times between the two points of a signal.
