Communicating is the act of giving, transmitting, or exchanging information. A key element in developing a device such as a computer is establishing a method of communication, both internally (for the transfer of information between hardware components) and externally (with the outside world). In this chapter, we discuss how a computer processes data and communicates (transmits information) with its user. Understanding this process is fundamental to understanding how computers work.
