Chapter 1 Data Representation Pdf Data Compression Computer In most modern architectures, the smallest unit on which the hardware operates is a sequence of eight consecutive bits called a byte. the following diagram shows a byte containing a combination of 0s and 1s: numbers are stored in still larger units that consist of multiple bytes. This chapter provides essential concepts regarding data representation in computer systems, including binary and hexadecimal numbering systems, data organization, and operations on binary values.
