Most D&D games are set in fantasy land. Not earth before 1920. So people are as literate as you decide them to be.
In any case mapping is an abstraction. Up to the group if the characters are mapping or not. Mapping may serve somewhat to bridge the gap between the vast distance from where the players are and the virtual word of the character.
While it may be unrealistic for the players to have a map accurate enough to find there way around a large dungeon level without getting lost - it is also unrealistic for the characters to get as disoriented as players would get among a group of players who don't map and who only have the GM's description and not immersion in the physical environment to help them.
And mapping could stand for various means the pcs take to keep oriented, such as making chalk marks on walls etc.
