Since computer terminology can often be one of the biggest stumbling blocks to understanding the world of personal computers,I've tried to make things a bit easier by defining new terms at the beginning of the chapter in they first appear

Up to this point, most of the information in this book has been written from the standpoint of the personal computer as a standalone machine. One power of computing, however, is in linking several computers into what is called a local area network (LAN).
Personal computers can be linked directly to one another through a terminal network connected to a mainframe computer, or though smaller minicomputers that link personal computers within specific offices or departments. These minicomputers, in turn, might be tied into a larger mainframe (or host) computer. Generally, all connections are made either by direct cabling or through existing telephone lines.
In order to allow personal computers to communicate with one another, three things are needed:
1. A communications card, which is plugged into a computer to connect it to the network
2. Cabling and some control machinery to keep everything functioning in harmony
3. Software
The software is perhaps the most important ingredient, because it will have the biggest effect on the results a network is able to achieve.
Networks are valuable because they allow people to share information almost instantly. Let us say that a worker has a memorandum or some budget files that he or she would like to share with someone else on another floor. Using the network concept, 11w information could be put together on one personal computer and then sent directly to the second system. In many networks, the sender may even direct something straight to the recipient’s printer to produce a paper copy. It is important for those who plan to use a LAN to first decide what they want the network to do. Options range from sharing files easily and allowing many people to access them, to simple communications such as electronic mail. Other considerations include deciding what should be sent (voice, video, and data communications are all possible), and determining whether or not every personal computer in the network needs such capabilities. These considerations are what make the software so important, because programs differ substantially in terms of the services they can deliver.
