The challenge posed by the explosion of microcomputers is toprovide access to more than one system and to integrate single computers into a local areanetwork (LAN) or a regional or national network so that computers can talk to each other andshare data. 　　One terminal can be made to do many things. Each one can talk to the main computer anddistribute the information obtained to many individuals or businesses. To do this, computerlanguage must become more standardized. International computer language committees arestudying the possibility of developing a language more like English, which will be moresuccessful and easier to learn than the symbolic and technical languages now in use.Telephones and cable will be used to mix voice and data. Television sets will perform thefunctions of transmitting, receiving, printing, copying, and talking. Small micro-computerswill be linked in a national network that will create a demand for writing, demonstrating, andserving the new software. A person with an analytical mind will find a creative challenge indeveloping new hardware and software. Today’s computer industry is seeking greateraccessibility, availability, and compatibility through wider interconnecting systems. This willprovide many jobs for the right people.
