What's the difference between domain and topology?

Domain


Definition:

  • (n.) Dominion; empire; authority.
  • (n.) The territory over which dominion or authority is exerted; the possessions of a sovereign or commonwealth, or the like. Also used figuratively.

  • (n.) Ownership of land; an estate or patrimony which one has in his own right; absolute proprietorship; paramount or sovereign ownership.

Topology


Definition:

  • (n.) The art of, or method for, assisting the memory by associating the thing or subject to be remembered with some place.

Example Sentences:

  • (1) The scheme is based on topological information, i.e.
