There are two choices in networking a number of computers. Most larger firms and larger networks tend to use the client-server model. The client-server model is usually significantly more expensive because the server is a powerful computer with a lot of RAM and a very large hard drive. The client- server software, generally Novell or Windows NT, can also be very expensive. David was fortunate in that his partner's son was not only a law student but also a computer wizard who helped him consider the various options and assisted with the installation.
Hardware upgrades .
Since he had decided to keep his existing computers, he wanted to upgrade them to a level where each machine could run Windows 95 and Windows 95 programs efficiently. He upgraded each machine with a 100Mhz 486DX processor, put either 16 or 32 megs of RAM in each machine and installed 540 megabyte hard drives on each machine. He would have upgraded the processors in each computer to some level of Pentium processor, which is desirable for running Windows 95, but was told that his computers could not be so upgraded. If you already have computers running Windows 95 and 16 megs of RAM, you probably will not need to make any hardware upgrades. Otherwise, you will probably want to put 16 megs of RAM in each computer.
