Setting up a client/server network is easier than you might think. There
are seven basic components, some of which are optional:
Desktop Computers
Identify the desktops or workstations you would like to network.
Server
Purchase a server with the right processing power, as well as expandability
and availability features to meet your business needs and number of users.
Cables
Connect workstations together and to the server with cables. The
cable serves as the conduit along which data is sent between devices. Cables
can range from a twisted pair cable (RJ-45), which is similar to standard
telephone wire, to a fibre-optic cable, which is faster and more secure but
often expensive.
Network Interface Card
A "NIC", or network interface card, is a broad-level product that fits into
a PC, workstation, or server that allows the computer to talk to the rest
of the network. Whereas a desktop NIC is installed in a desktop PC or workstation
and only supports a single user, a server NIC is used in a server to connect
many users and supports business-critical applications. A server NIC provides
increased reliability, reduced CPU overhead, and better overall performance.
Software
Some type of networking software is required to facilitate communication
among the workstations and the server. The Network Operating System runs
on the server and allows users to share information and peripherals that
are attached to the network. In addition, each workstation must run client
software in order to communicate with the server.
Hubs
In some network configurations, a "hub" connects all of the computers. The
server connects to the hub, and each of the workstations is plugged directly
into the hub. Because the computers do not need to be connected to each other
in a serial fashion with this configuration, they can be dispersed in multiple
locations, such as separate offices, or even different floors of the building.
Cables can generally be run about 100 yards (RJ-45), enabling a very flexible
configuration. If you have more users than ports on your hub, additional
hubs can be connected, or "cascaded" to the first hub. Some of the most common
hubs used by small businesses are 4-, 8-, and 16-port hubs.
Tape Backup Units and Uninterruptible Power Supplies
Premio highly recommends utilizing tape back-up units and universal
power supplies with your network. Tape back-up units assist users in storing
and protecting valuable information that your company may not be able to
function without. Uninterruptible power supplies help protect your files
against power surges and outages. |
