How do I connect the computers?
• The first thing you need to do when you
begin to physically set up the network is to
install cable. You have to select the correct
type of cable then be aware of some basic
guidelines for the proper installation of the
cables, known as transmission media.
Cables and Connectors
• Coaxial cable has a
solid copper wire at
the core, which is
surrounded by an
insulating layer of
plastic.
• A British Naval
Connector (BNC)
connects lengths of
coax cable, and
connects the cable to
the NIC.
Twisted-Pair Wiring
• There are different
categories of twistedpair wiring, each
designed to transfer
data at different
speeds.
• An RJ-45 plug
connects twisted-pair
cable to computers
and other devices.
Twisted-Pair Cable
• Students can visit the Cables to Go Web
site to get more information about cables
and pricing of various types of cabling.
• The site is online at
http://www.cablestogo.com.
Fiber Optic Cable
• Fiber optic cable
differs from other forms
of network cabling
because it transmits
pulses of light rather
than electrical pulses.
• This expensive and fast
cable medium is
popular for long
distance backbone
segments that might
link states or countries.
Installing the Cable
• Students can study the steps in the Wire
My House for Networking section of the
Home PC Network Web site at
http://www.homepcnetwork.com.
• There is a more complete review of wiring,
with pictures for each step at
http://www.swhowto.com.
• Determine the needs and level of your
students and you might want to refer some
students to this Web site.
Can I create a network without
wires?
• Many networks today use wireless
technologies to connect devices to the
network.
• A wireless network eliminates the cables
that connect each device to the network,
enabling you the freedom to move away
from the network and still retain access to
those resources, as long as you are within
range of the transmitter.
Wireless Networking
• You can use wireless
devices in a variety of
ways.
• Wireless technology
can be used on:
– Laptops
– personal digital
assistants (PDAs)
– mobile phones
– two-way pagers
– automobiles
Using Wireless Systems
• Students can visit some of the online sites
that provide information about wireless
systems, including:
– Linksys (http://www.linksys.com)
– Proxim (http://www.proxim.com)
– 3com (http://www.3com.com)
How do I install the hardware?
• You can look at the specification sheets for
the hardware to ensure it offers all the
features you need, such as network
interface cards, a large enough hard drive,
a fast enough processor, and other
capabilities you might want.
• Once you have the hardware, you need to
be careful where you place the computers.
• Once the hardware is in place, you are
ready to start setting up the software.
How do I set up the software?
• The first step in connecting the hardware over a
network is to install the network operating
system. In many systems, the network operating
system is already on the computer when you
purchase it.
• Before installing the software, make sure that all
cables are plugged in, all connection devices
and resources are powered on, and that
everything is functioning. During the process, the
software may need to access the various
components.
How do I choose an ISP?
• Before you actually connect to the Internet, you
must first select an Internet Service Provider
(ISP). An ISP is a company that charges a fee to
provide a doorway to the Internet.
• You need to consider several things when
determining the best ISP for your needs:
–
–
–
–
Services
Size
Contracts
Support and Equipment
What type of connection do I
have to the Internet?
• There is more than one way to connect to the
Internet. You can have what is known as a dialup connection in which the modem uses the
standard phone line to dial up the ISP and
connect to the Internet. This is the slowest
method and is not usually efficient in the
business world.
• You can also create a high-speed Internet
connection that provides faster access to the
Internet. There are several different types of
high-speed connections.
What else do I need to know to
get connected?
• As you learned earlier in this course, a
protocol is a rule or guideline that ensures
accurate communication.
• Both the network computers and the ISP
must be able to understand each other so
you can use the Internet.
• Any computer that connects to the Internet
uses the TCP/IP Protocol Suite to
transfer information.
What is the future of networking?
• The future of networking is an open book.
Even looking ahead fifteen years is
difficult.
• Just fifteen years ago, the World Wide
Web didn't exist. There was no such thing
as a browser. There were no laptops, no
PDAs.
• So what's next?
– What is the future of networking?
– Can you even imagine the future?
What You've Learned About
Creating a Network
• In this lesson, you have created a network.
From selecting and installing cable and
hardware to installing software and
configuring the system, you have
examined the steps necessary to get a
network up and running. You have also
looked at the basics of setting up a home
network.
