CHAPTER 7lNPUT/OUTPUT (I/O) AND INTERFACINGINTRODUCTIONThe input/output section, under the control of the CPU’s control section, allowsthe computer to communicate with and/or control other computers, peripheraldevices, other subsystems (display and communication), and systems (fire control,sonar, FTAS, and the like). Take the time to understand your computer’s I/Osection: its organization, operation, and interfacing format. The latter is veryimportant because if the interfaces for the computer and the external equipment donot match, your computer will not talk to anyone.After completing this chapter you should be able to:Understand the terminology associated with I/ODescribe how your computer’s input/output is organized-hardwareand softwareList and describe how the different operating modes affect the transferof informationDescribe the circuits and their functions in I/O operationsDescribe the categories of I/O operationsRecognize how the external equipment in your computer’s system isconnectedList and describe the types of interfaces used in I/O operationsDescribe serial data I/O operationsDescribe parallel data I/O operationsLet’s begin your study of input/output with how it is organized in yourcomputer. The different types of computers vary in their organization of I/O, butthe basic operations of the serial and parallel interfacesare similar regardless ofthe computer types.TOPIC 1—TERMINOLOGYANSI—American National Standards Institute.You should be familiar with the following termsDataCommunicationsEquipment(DCE)—Anybefore studying this chapter:device that communicates the data; for example, amodem.ANEW—Army-Navy Electronic Warfare.7-1
