Peer-to-Peer
A star network contains a single, centralized hub or switch
through which all the devices in the network communicate.
Network Connection
• Cable modem for the internet
• Shielded Copper twisted pair
• Least expensive
• Foil shielding protects against electromagnetic interference and
prevents signal detection and interception.
• Easy to work with and install
• Both Analog and digital data transmission
• If a portion of a twisted-pair cable is damaged, the entire network is
not shut down as it may be the case with coaxial cable.

Question: 4
You are part of a team of consultants. You have been hired by
a national organization, which will be holding its annual meeting in
San Francisco in Moscone Center. There will be several hundred
people attending and many of them will be using laptops. They need
networking so that they could communicate with each other. What is
the best solution for them?
Wireless
 Wireless networking is used to meet many needs. Perhaps the most common use
is to connect laptop users who travel from location to location.
 Wireless technology releases us from copper wires. A user can have a notebook
computer, PDA, Pocket PC, Tablet PC, or just a cell phone and stay online
anywhere a wireless signal is available.
 Wireless communication is the
transfer of information between
two or more points that are not
connected by an electrical
conductor.
 Wireless operations permit
services, such as long-range
communications, that are
impossible or impractical to
implement with the use of
wires.
The following situations justify the use of wireless technology:
 To span a distance beyond the capabilities of typical cabling,
 To provide a backup communications link in case of normal network failure,
 To link portable or temporary workstations
 To overcome situations where normal cabling is difficult or financially
impractical, or
 To remotely connect mobile users or networks.
Wireless Hardware
 Wireless Routers
 Wireless Repeaters
Wireless Routers
 A wireless router is a device
that performs the functions of a
router but also includes the
functions of a wireless access
point. It is commonly used to
provide access to the Internet or
a computer network.
Wireless Repeaters
 A wireless repeater (also called
wireless range extender) takes an
existing signal from a wireless
router or access point and
rebroadcasts it to create a second
network. A wireless repeater is
used to bridge the gap. It also can
be a specialized stand alone
computer networking device.
