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.

full mesh topology for the ultimate in fault tolerance. The full mesh topology using Cat 6 cabling will be cabled

into a 60 port switch A printer will also be attached to each switch Each locations switch will have a router ported into it ready

to send and receive data in and out from the Internet but first…

Continued… Each router will have a firewall on the outside of it armed with

protocols that allow only authentic and authorized packets to pass through.

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 workstationsTo overcome situations where normal cabling is difficult or financially impractical, orTo remotely connect mobile users or networks.

Wireless Hardware

Wireless Routers

Wireless Repeaters

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.
