Abstract

Summary The electronic transfer of information is one of the most exciting and at the same time most frustrating uses of microcomputers because there are potentially nine components that must all work together. These are: o (1) the sending computer and its operating system, (2) the communication software compatible with the sending computer, (3) the hardware for transferring information out of this computer (e.g., communication port), (4) a modem or other device for converting the signal into one transferable over telephone lines or network, (5) the physical link between computers (e.g., cable, telephone line), (6) the modem or other device on the other end of the line to convert the signal to one the receiving computer can understand, (7) the hardware for transferring information into the receiving computer, (8) the communication software compatible with the receiving computer, and (9) the receiving computer and its operating system. Getting all of these components to work together is a challenge. It takes time, patience, and often some help from experts. It is hoped that this installment of Microcomputers In Evaluation has given you the basic information and insights needed to decide which form of communication is right to meet your need for linking computers.
