Revision of Basics
Although it is assumed in this book that the reader has enough knowledge of various number systems ( binary, octal and hexadecimal and their relation with decimal number systems) and digital electronics but few important topics are disused in this chapter in brief to revise them as they are useful to understand the working of microprocessor in a better way. For detail knowledge one must refer some books of number systems and digital electronics.
