Chapter 2 :Data representations and computer Arithmetic2.1. Objectives This chapter covers the most common methods that computer systems user to represent data how arithmetic operations are performed on these representations. It begins with a discussion of how integers and floating-point numbers are represented as sequences of bits. After reading this chapter, you should1. Have an understanding of how computers represent data internally at both the bit-pattern and the electrical-signal level2. Be able to translate integer and floating-point numbers to and from their binary representations3. Be able to perform basic mathematical operations (addition, subtraction, and multiplication) on integers and floating-point numbers 2.2. From Electrons to Bits (BInary digiT) Modern computers are digital systems, meaning that they interpret electrical signals as having a set of discrete values, rather than as analog quantities. While this increases the number of signals required to convey a given of information, it makes storing information much easier and makes digital systems less subject to electrical noise than...
