Two MIME content-types are "text/html" and "application/postscript". Discuss why HTML has placed under the primary type "text", while Postscript has been placed under the primary type "application".

Answer:

HTML was assumed to be readable by a human as text, and was assumed not to contain executable code which might cause security problems. None of these assumptions is really true, and many people think it was a mistake to put HTML under TEXT. Postscript, however, might be more security dangerous than HTML.
