No, we don't do your homework for you. Read the wikipedia article, and if you have specific things that you don't understand about it, post the specific questions here and we'll try to give you some hints to clear up your understanding.

Is ROM random access ?

Is ROM random access ?

I could give you the answer, but if this is a homework question, then I'd be doing your homework for you. Instead, can you define random access for me? Random access as opposed to what kind of access?

Once you define random access, you can use a datasheet for a typical ROM to answer your question. Like the 27C512 ROM, for example:
