"Consider as an example a typical computer of that era which might have had a 16 bit address field in its instructions and 4096 words of memory.A program on this computer could address 65536 words of memory."
I don't understand some of the terms. What is meant by "16 bit address field" , "words of memory" . And what does "4096" denote ?
I don't get the feel of what the author is saying.Please explain the whole sentence.
