Week 4: Wired, Wireless LANs, and Backbone Networks
Discussion
LANs (graded)
Sally’s Shoes (mini case): Sally Smith runs a shoe store in the mall that is about 30 feet by 50 feet in size,
including a small office and a storage area in the rear. The store has one inventory computer in the storage area
and one computer in the office. She is replacing the tow cash registers with computers that will act as cash
registers but will also be able to communicate with the inventory computer. Sally wants to network the
computers with a LAN. What sort of LAN design would you recommend? What would be your suggestions to
improve the performance of this LAN?

Class, what sort of LAN design would you recommend for Sally's Shoes?

Sally should use 10BaseT or 100BaseT network solutions. 10BaseT is an Ethernet solution
which helps in transmitting data at 10Mbps over the telephone wires or twisted pair wire.
100BaseT is an Ethernet solution which helps in transmitting data at 100mbps.
Peer to peer or dedicated networks can be used. In peer to peer network, all the
computers on the network work as a client as a server.
No dedicated server is required in peer to peer network. While in the dedicated network,
one or more computers work permanently as the dedicated servers.
Sally should use dedicated network as she has to safe her inventory system and
dedicated network provides long run
Also large databases and large file can be handled easily. By using the following dedicated
network, sally can connect her LAN to another network.

A network circuit is where computers must be physically connected by
network circuits to the other computers in the network.
Yet, Wired LAN’s provide many options for UTP, cable, shielded,
twistedpair (STP) cable or fiberoptic cable in a host of ways that can
be connected for transmission of data sent to the device.
However, in telecommunications, a circuit is a discrete (specific) path
between two or more points along which signals can be carried.
Unless otherwise qualified, a circuit is a physical path, consisting of
one or more wires (or wireless paths) and possibly intermediate
switching points. A network is an arrangement of circuits. In a dial
up (switched) connection, a circuit is reserved for use by one user for
the duration of the calling session. In a dedicated or leased line
arrangement, a circuit is reserved in advance and can only be used by
the owner or renter of the circuit.
Network circuits in my home network, a major carrier has connected
(ONT) 100 BaseT (Fiberoptic) and now will offer at some point (CAT
7/62.5/50). Currently, Fios running into my home is wireless and is
bundled Internet access, telephone and video (television) and a
wireless printer for printing capability to print from any location within
the home.

RE: LAN's Jermaine Huggins 9/18/2016 10:03:52 PM
I'll suggest having a wired LAN. Also because of the distance I'll suggest using STP
cables as running fiberoptic might just cost extra.
In my home, I have STP cable that runs from my modem to my wireless router with
switching capabilities that connects all of my devices, computers, laptops, and printer.
Her needs are similar so she can do the same, except the need for wireless.

I suggest Sally to use a simple. 10BaseT
Ethernet or at most a 100BaseT network
solution. The network can use wither peer to peer
or a dedicated server. However, a dedicated
server would be preferable for the long run and
cost will be an overriding concern because this is
probably a small business. As a matter of fact,
many organizations today install switched
100BaseT for their wired LAN's relatively because
of low cost and fast.
Due to the small size of the mall store, I would recommend a wireless LAN for Sally's shoes.
The wireless access point or router should be omnidirectional since the store needs network
connectivity with the computer in the storage and the one in the office. The router should be
connected to a WAN possibly provided by a service provider such as ATT, Comcast, etc. In
addition, each of the computers and cash registers should be equipped with equivalent TCP/IP
ports and NICs in order to be able to tap into the wireless network provided. In order to
improve the performance of the LAN, the wired portion of the router should have a high
bandwidth capable of maximizing the data utility of the network.

Rather, we mean actual networking, the kind that lets your office’s technology
devices communicate with each other and with the world. Read on for a rundown on
what you need to consider when setting up a small business network from scratch.
CAT 3 is still ubiquitous due to its use with phones, but it’s not suitable for modern
Ethernet devices. Use of 100 Mbps Ethernet devices requires CAT 5 cable, while 1000
Mbps (a.k.a. Gigabit) devices require at least CAT 5e. Speaking of Gigabit, since
virtually all modern desktops, notebooks, and servers support it and the cost of
Gigabit Ethernet switches (the devices that provide additional ports to expand your
network) is not much higher than for 100 Mbps Ethernet switches, in most cases it
will make sense to go with Gigabit.
I would recommend a wired LAN with unshielded twistedpair (UTP) cable. Maybe category 5e
UTP cable that is rated for 1000 Mbps in a LAN that runs at 100 Mbps. She is in a small
enough space, it sounds like, that this would work. A single space, not taking up multiple
floors.
She could opt for fiberoptic cables instead of UTP which saves on space due to the thinner
wires, however it costs more. It depends on which option she would prefer and how the office
is set up if it is set up to handle the thicker wire, then UTP would be a good costeffective
measure.,

I agree that unshielded twistedpair cable would be the best to use. Unshielded
twisted pair is the most common kind of copper telephone wiring. Twisted pair is the
ordinary copper wire that connects home and many business computers to the
telephone company. To reduce crosstalk or electromagnetic induction between pairs of
wires, two insulated copper wires are twisted around each other. Each signal on
twisted pair requires both wires. Since some telephone sets or desktop locations
