In this chapter we will see how these binary numbers are coded to represent characters in computers. Thus the goal of this chapter is to present the formats used in computers to record data. Although many coding schemes have been developed over the years, we will be discussing only the most commonly used computer codes. Numeric data is not the only form of data that is to be handled by a computer. We often require to...
