All computers do not speak the same language, but if they are going to be networked they must share a common means of information transfer. As a local area network user there is nothing that you need be concerned about. Instead, we will take a look as some of the other software packages as they might be used by Martina, a fictional student at Southern Regional H.S. and president of the chess club. As previously mentioned, a physicist on the east coast who has an account on a west coast computer could run high level physics simulation software via telnet. The fact is that telnet need not be that fancy and an account on the computer isn't always necessary.
Many universities allow public telnet access.
All you need to know is the public logon and a few telnet commands. Using telnet, Martina could play chess against some of the top computers in the country. Listed here are some of the sites that allow public access to chess computers. In some cases you can play live against other people. We have not yet covered telnet use, and improper use can tie up resources at both the host and remote system.
