The tele-phone system is therefore a goodplace to begin assessing the impactof the transistor. From the viewpoint of the tele-phone user, the transistor (as a keycomponent of undersea cables andcommunication satellites) hasmeant a great improvement in thequality of international calls andthe speed with which they are putthrough. Similarly, transistors inlong-distance transmission systemsand in switching systems are a ma-jor factor in the ease and speedwith which long distance calls can.
