Solutions Guide - Types Of Networks
What type of network is right for your business?
There are two basic types of networks depending on the number of computers
in your network: Peer-to-Peer and Client-Server. Peer-to-Peer network:
If you have five or less computers, the simplest and least expensive way to
connect your computers together is a Peer-to-Peer network. In a Peer-to-Peer
network, each computer is outfitted with a network interface card (NIC) and
is connected with a cable to a central device called a hub.
Peer-to-Peer Network
Each computer is an equal (or peer) to all other computers on the network.
No central computer stores files or enforces security on the network.
Each computer can share files and attached peripherals such as printers, plotters,
scanners and CD ROMs with all other computers on the network. Each user must
act as an administrator over his/her own PC.
This is a simple and cost effective solution for companies that do not need
to share large files or share applications. If you are currently running Windows
3.11 or Windows 95, you already have built-in networking support.
Choose Peer-to-Peer when:
- You have five or fewer PC’s.
- You want to share files and printers.
- You want easy installation.
- You want users to manage their own computers.
- You do not frequently share large files such as CAD or graphic files.
- You’re on a tight budget.
Client-Server Network:
If you have more than six computers, a Client-Server based network may better
suit your needs. In this type of network, "clients" or (desktop PC’s)
are connected to a more powerful computer called a "server". Servers are computers
optimized for performance and reliability.
The server is a central repository for files and applications and maintains
the security on your network. An administrator sets permissions for access
to computers, printers and data on the network. Servers also provide a platform
to run shared applications such as databases, accounting, manufacturing and
inventory software. File servers must have a server-based operating systems
installed such as Windows Server, Novell NetWare and UNIX. File servers may
also act as e-mail servers, database servers, Internet or Intranet servers.
Choose Client-Server when:
- You have six or more computers.
- You need strong central security and reliable back up.
- You need the additional speed and performance.
- You frequently share large files.
- Employees need remote access to your network.
- You want all users to be able to simultaneously access the Internet and
receive e-mail.
Wide Area Networks (WANs) connect two local area networks (LANs) together
over telephone lines enabling seamless connection between two remote sites.
These lines can be dedicated private lines leased from the Telephone Company
or public lines switched through the Telephone Companies network. WANs can
be setup between your office and other branch or main offices.
This enables remote offices to synchronize data, transfer and back-up important
files, exchange E-mail, etc. Many different WAN technologies are available
dependent on your companies bandwidth needs.
