ASA in transparent mode has no ip addresses set to its interfaces, "bump in a wire" in other words. It has the same network on inside and outside interfaces. It can not perform routing and NAT

ASA in routed mode has ip addresses set, it can perform routing, it is seen as a hop for other devices and you can do NAT with it.

If you are using ASA to access internet, you would certainly need NAT, since your inside address are not globally routable.
