What is the major differences between Artiodactyla and Perissodactyla?

The even-toed ungulates(Artiodactyla) are ungulates (hoofed animals) whose weight is borne about equally by the third and fourth toes, RATHER THAN mostly or entirely by the third as in odd-toed ungulates (perissodactyls) such as horses.

Artiodactyla comes from (Greek: ἄρτιος (ártiOS), "even", and δάκτυλος (dáktylos), "finger/toe"), so the name "even-toed" is a translation of the description.[1] This group includes pigs, peccaries, hippopotamuses, camels, chevrotains (mouse deer), deer, giraffes, pronghorn, antelopes, sheep, goats, and cattle.

An odd-toed ungulate is a mammal with hooves that feature an odd number of toes. Odd-toed ungulates comprise the order Perissodactyla (Greek: περισσός, perissós, "uneven", and δάκτυλος, dáktylos, "finger/toe").[2] The middle toe on each hoof is usually larger than its neighbours. Odd-toed ungulates are relatively large grazers and, unlike the ruminant even-toed ungulates (artiodactyls), they have relatively simple stomachs because they are hindgut fermenters, digesting plant cellulose in their intestines rather than in one or more stomachs. Odd-toed ungulates include the horse, tapirs, and rhinoceroses.
