After carefully interviewing the Stake holders of the Leonard Cooper Charter School, several issues were observed. The first
noticeable concern was the print server. Their management of print jobs on the print server are called into question because of
the many collisions on the print server. They are presently using a half–duplex system for their print jobs. A half–duplex
system provides signal communication in both directions, however only one direction at a time. A good example of this
technology might be two–way radios. The person listening must wait until the transmitter concludes the signal transmission
before responding to the call otherwise a collision will occur and ... Show more content on Helpwriting.net ...
In addition, there seems to be some connectivity issues with the backbone of the network. One of the biggest complaints
included not being able to use Voice over IP. Therefore, a more suitable media that will increase their network speeds needs to
be put into place. A final issue that needs to be addressed is the possibility of adding class room computers to the network. A
cost effective, yet scalable solution is substantial.
Recommended Solution
The best alleviation for print job collisions is to upgrade from a half–duplex to a full duplex switched environment. Full–
duplex is a data communications term that refers to the ability to send and receive data at the same time. Legacy Ethernet is
half–duplex, meaning information can move in only one direction at a time. In a totally switched network, nodes only
communicate with the switch and never directly with each other. Switched networks also employ either twisted pair or fiber
optic cabling, both of which use separate conductors for sending and receiving data. In this type of environment, Ethernet
stations can forgo the collision detection process and transmit at will, since they are the only potential devices that can access
the medium. This allows end stations to transmit to the switch at the same time that the switch transmits to them, achieving a
collision–free environment (Pidgeon, 2011). Therefore, the 24 Port Switch is highly recommended. The solution is to

Company Manufactures Components For The Oil And Gas...
ENGINEERING MANUFACTURER Introduction: EngCo Company manufactures components for the oil and gas industry. It
is a cross–discipline engineering company, which combines electrical, mechanical and process engineering skills. The purpose
of the company is to produce custom–made components for large gas and oil companies across the globe. The company needs
a design to set up their data network. A report is needed to be written where the options for setting up their network will be
outlined, including details of how all services will be provided. Task–1: Physical Topology Diagram a) Chosen
Topology:Network topologies are categorized into the following basic types: 1. Bus Topology 2. Star Topology 3. Ring
Topology 4. Mesh Topology Among them Star Topology is more suitable for this network. b) Explanation of Choosing Star
Topology: In Bus Topologyall computers are attached to a single cable. So if any of the connection breaks down, the entire
network breaks down with it. It is difficult to move and change since they are all link up together. It 's difficult to troubleshoot
(justfortest.tripod.com, n.d.). In Ring topology, Data moves in a one–way path only. It is expensive because multiple cables
area needed and difficult to reconfigure. Simply not fault tolerant because a single cable fault can bring down the whole
network (justfortest.tripod.com, n.d.). In Star Topology, each computer is connected to a central point from a dedicated cable.

For the company DesignIT, I would use a LAN type of network (for local–area network). This networks several computers, a
mail (exchange) server, a database server and a file share server in one building and interconnects with each switch or
backbone. I chose this for this small space because it is less than 100 square feet and is all within a single dwelling. This way
the employees can all share their resources with one another, an intranet, database and printers.

DesignIT would only need a basic television package with a single receiver in their conference room and a 10–15 line
telephone service.
Point–to–point topology would not be useful because each computer is connected directly. Mesh topology requires many
cables and can handle a high–volume traffic. If the wireless access point or router fails it would only affect the computers and
devices in the particular area, same with switches but not connected by a cable directly from the wall. In DesignIT's case,
hopefully the failure is just in the access point so that at least the employees would have a medium–weak to weak wifi
connection. I would suggest a central backbone installed in ceiling above the reception area. CAT5 or CAT6 cables can support
up to 100 meters before signal degradation. These connections can be routed form the reception area ceiling coming out like a
star and then down the walls or separations and out to a port jack. Each workstation's PC would connect to their corresponding
wall Ethernet jack. In many workstation cases, the cable goes form the wall jack to their phone on their desk and back down to
their CPU which usually sits on the florr or a lower–sitting platform.
For a small company, like the last company I worked for (121 computers, 14 servers) or DeignIT, client–server networking
would be the best to implement. All the computers are set up like desk workstations and connected to the same network with
hubs.

These two layers perform routing and deals with end to end issues. The hospital currently uses a CISCO ASA 5510–VPN
router to connect to the internet. Finally the session layer, presentation layer, and application work together to make the
network operational. These three layers actually make all the data be visible to the end users. These layers also make the data
and network usable to the operator. Patton–Fuller utilizes Windows Explorer and its company's webpage for these layers
(Patton–Fuller, 2013).
Recommended Protocols For Patton–Fuller to fully utilize their potential networking power, the following protocols should be
utilized. Patton–Fuller should utilize a Gigabyte Ethernet Network for all its hardwired LAN connections. Gigabyte Ethernet is
part of the family of Ethernet computer networking and communication standards. The Gigabit Ethernet standard supports a
theoretic data rate of 1 gigabit per second. Gigabyte Ethernet networks are connected by CAT5e and CAT6 cabling (Gigabit
Ethernet, 2013). The Gigabyte Ethernet network should be accomplished by using layer 3 switch. A layer 3 switch is a high–
performance device for network routing. Layer 3 switches actually differ very little from routers. A Layer 3 switch can support
the same routing protocols as network routers do. Both inspect incoming packets and make dynamic routing decisions based on
the source and destination addresses inside. Layer 3 switches improve on the performance of routers

Our intention is to do the aforementioned in a manner that will allow us to manage all of the files and resources from a central
location by implementing a server to our current network architecture. Reasons to Change. In the past our peer–to–peer
network architecture served us well by providing us with a way to share our files and resources in a manner that did not require
much planning. Unfortunately, as a peer–to–peer network grows it becomes more difficult to maintain due to its lack of
centralized control which makes it un–scalable. With the addition of fifty individual workstations, security access and file
storage control remains in the hands of the user. For example, should someone decide to delete a company file, there would be
no way of knowing. Once there are more than five or six workstations attached peer–to–peer networks begin to pose as a
security threat that may cause loss of sensitive company data due to virus and spyware attacks. Fortunately advancements in
technology have provided a viable solution for rapidly growing small businesses such as our own called servers. Our Viable

This layer is also called the Workgroup layer.
6. Does this network need a core layer? What devices would operate at the core layer?
The core layer is considered the backbone of the network and includes the high–end switches and high–speed cables such as
fiber cables. This layer of the network does not route traffic at the LAN. In addition, no packet manipulation is done by devices
in this layer. Rather, this layer is concerned with speed and ensures reliable delivery of packets.
7. Is redundancy required at any layer of this network? If it is, where and how would this redundancy be added to the network?
What device or devices would be used to make this network redundant?
A goal of redundant topologies is to eliminate network down time caused by a single point of failure. All networks need
redundancy for enhanced reliability. Network reliability is achieved through reliable equipment and network designs that are
tolerant to failures and faults. Networks should be designed to reconverge rapidly so that the fault is bypassed.
In a redundant mesh topology network devices are connected with many redundant interconnections between network nodes.
In a true mesh topology every node has a connection to every other node in the network. A mesh network with redundant
connections is an example of a redundant topology. The level of redundancy can be measured by network connectivity.
On a redundantly connected network if a

Computer Dynamic 's Current Data And Communication Network
The purpose of this report is to assess Computer Dynamic's current data and communication network. The objective of the
report is to offer a proposed solution for a modern network that meets the organisation's needs. A review of existing network
was conducted; school management and number of students were observed. Current network performance was provided by the
management. A physical assessment of the whole school was conducted. Findings The existing network is exhibiting
congestion, bottlenecks, poor speed and is not adequate for growth in line with company strategy . There is no physical
connection between the two buildings occupied by the organisation. The school is already sharing information through a VPN
site to site tunnel. The current VPN approach throughout the school is not efficient. There is currently a disaster recovery
opportunity in place of school data. Recommendations An investment is required to form a physical network connection
between the school, Fibre Optic is suggested. An investment in layer 3 switching technology is recommended to take
advantage of the Fibre Optic upgrade An investment in hardware for disaster recovery is highly recommended. Two major

Data security: Magnetic fields and current induction work in two ways, they just don't generate noise in signal carrying
conductors; they also let the information on the conductor to be leaked out. Since there are no radiated magnetic fields around
optical fibers; electromagnetic fields are confined within the fiber. This makes it impossible to tap the signal being transmitted
over fiber cable. Thus the fiber cable is the most secure medium available for carrying sensitive data. iii. Non Conductive: A
serious concern with outdoor cables in certain computer networks is they can be hit by lightning, causing destruction to wires
and other cables that are involved in the network. Fiber optic cables can be made non–conductive by avoiding metal in their
design. These kinds of cables are economical and standard for many indoor applications. Outdoor versions are more expensive
since they require the special strength members, but they can still be valuable in eliminating ground loop and protecting
electromagnetic equipment from surge damage. iv. Eliminating Spark hazards: Fiber optic cables do not produce sparks since
they do not carry current. Most electric potentials create small sparks which can be extremely dangerous in areas like chemical
plants or oil refinery where air is contaminated with potentially explosive

smaller "areas" on the network. Typically to exchange routing tables between two to four routers only. Finally BGP is used
with the edge devices. BGP was designed as the main routing protocol of the Internet. IPX was never an option. This was used
primarily with the older Novell networks. Class A IP's are used in their environment. This gives them great flexibility to split
the network into smaller subnets based on each sites needs. Class D & E are not used. Class D is typically for multicasting. E is

INTRODUCTION
EVOLUTION OF IEEE 802.3 STANDARD [1]
In 1970s, Dr. Robert M. Metcalf developed a network, Alto Aloha Network that enabled the sharing of printers to personal
workstations at data rate 3Mb/s. In 1980, DEC, Intel, and Xerox released the DIX Standard for Ethernet that made Ethernet
open standard for network operations.
Further, Institute of Electrical and Electronic Engineers (IEEE) created a working group 802 which developed network
technology standards numbered as 802.x, such that x was the subcommittee number who developed it. So, in 1985, the
subcommittee 802.3 developed Ethernet standards called Carrier Sensing Multiple Access with Collision Detection
(CSMA/CD).
Relation To OSI Model [1]
IEEE 802.3 standard lies in Physical and Data Link Layer of the OSI model. The Physical Layer is responsible for transmitting
electrical impulses across the physical channel without any knowledge of bits. Further, the Data Link Layer is divided into

CCHB uses private IP addressing (10.0.0.0) and a Proxy / NAT Server for Internet access. This helps improve the speed at
which users can access pages on the Internet because visited pages are cached at the server for faster future retrieval. The use
of a NAT server hides the internal addressing, which protects against 'smurf' attacks.
5 5. VLANS
The switches have been configured to implement Ethernet VLANs (some for security reasons, some to reduce network traffic).
The Cisco Catalyst 6500 switch is capable of supporting up to 256 VLANs on a single RSM. The CCHB currently has 6
VLANs implemented: ▪ Oncology system ▪ PACS system (radiology images) ▪ Patient monitoring system ▪ Wireless network ▪
Auckland City Hospital ▪ Other (general) users
Each VLAN has its own IP range / subnet.

Process Of Top Down Network Design
Introduction I chose this particular topic not because it's easy, but because it will enhance the skills I already have. The topic
selection should really not matter that much, since the topic will merely gauge to see what I will learn, and also challenge my
ability to find solutions to various problems that I will encounter throughout this course. This will begin with week one and
ending with week seven, provided with a business network scenario I will have to decide based on assumptions and
requirements to either upgrade or design a network from scratch. My reasoning for this is simple, that if I apply what I am
suppose to learn in this course, I should be able to quickly apply the process of top–down network design, keeping in mind the
customers business goals and requirements, I will be successful in providing a justified solution or network implementation for
any given customer and any given business scenario. That is the main goal of any structured systems analysis; it is to more
accurately represent customer's needs. (Oppenheimer 5) My approach in this project and provided topic will be to apply a top–
down network design process. I know that a top–down design is a process of reducing of an existing system into smaller parts,
in order to understand its compositional sub–systems, essentially simplify given the problem scenario. Designed overview of
the system, specifying, but not detailing any first level subsystems. Thus, every subsystem is refined in greater detail,

Printing is a really problematic area for us. You see, we have over 50 networked printers in this building. Although we do need
the printers, we need some way to consolidate the management of print jobs, as the queues on these printers often are filled. We
also need to navigate to each printer individually to clear them. There has to be a better way because this is ridiculous.
Collisions have become a problem for us as well since we started to add new computers a few years ago. In the morning when
everyone gets in, network performance slows to a crawl because everyone is busy on the network with their morning

San Implementation Essay
SAN implementation over Gigabit Ethernet
A Storage Area Network is virtualized storage.
A storage area network (SAN) is a dedicated, centrally managed, secure information infrastructure, which enables any–to–any
interconnection of servers and storage systems.
A SAN can be configured to provide a nearly infinite pool of storage that you can grow and move between servers as they need
it. The storage can be added to and removed without requiring the server to be rebooted. The services provided by the server
continue to operate without interruption.
The primary purpose for implementing a SAN is to provide a large storage pool that multiple hosts could access. Common
storage configurations involve direct attachment of storage to a host. ... Show more content on Helpwriting.net ...
With a SAN, virtually unlimited expansion is possible with hubs and switches. Nodes can be removed or added with minimal
disruption to the network.
What is Gigabit Ethernet.
Gigabit Ethernet supports 1000 Mbps over Ethernet media. Because it is similar to existing Ethernet and Fast Ethernet
standards in that it uses the same frame format and collision detection mechanisms, Gigabit Ethernet is easy to integrate with
existing Ethernet networks. It was designed as a Ethernet backbone switch–to–switch and switch–to–server technology.
To provide the speed increase from 100 Mbps Fast Ethernet up to 1 Gbps, several changes needed to be made to the physical
interface of Gigabit Ethernet versus Fast Ethernet. It was decided that Gigabit Ethernet will look identical to FibreChannel at
the physical layer. By taking advantage of the existing high–speed physical interface technology of FibreChannel while
maintaining the IEEE 802.3 Ethernet frame format, backward compatibility for installed media, and use of full or half–duplex
carrier sense multiple access collision detect (CSMA/CD), customers will be able to use their existing knowledge base to
manage and maintain gigabit networks. They would not have to throw away their existing network infrastructure.
Gigabit Ethernet is intended for Fast Ethernet backbones and switch to server links where existing Ethernet networks are being
aggregated onto the faster Gigabit Ethernet speeds. A company planning a

Atm Is A Complex Technology
4. Technology comparison
4.1 General
ATM is a complex technology. There are tons of standards covering numerous characters of ATM [2]. One can assume that the
complexity is pretty much due to the nature of ATM of attempting to be one–solution–fits–all, technology from LAN to WAN,
for all data types. The connection–orientation also mainly provides to the overall complexity, because it needs the actuality of
explicit signaling and routing protocols. The complexity is constrained by the powerful abilities in ATM, still, not all need
them.
Although there are various standards, some components of the technology had to remain for standardization for a long time,
and this diminished down the selection of the technology. The PNNI–interface was not systematized until 1996, and remaining
a major interface between public ATM networks, the interoperability between public networks was not possible.
Interoperability is still an argument.
In diversity, the attraction of Ethernet is its simplicity. Just a few standards cover the entire technology. The technology is
simple to grasp and deploy. This is the primary cause of the universality and wide choice of Ethernet.
A numerous interest for ATM is that it is autonomous of the underlying transport mechanism. ATM does not define Media
Access Control (MAC) mechanism (lower part of data link layer, the another being LLC) or the physical layer, whereas
Ethernet does illustrate these. As an outcome, ATM can run on top of various transport

voice demand remains stable. What was once a predominantly circuit switched network handling mainly circuit switched voice
traffic has become a circuit–switched network handling mainly IP data. Because the nature of the traffic is not well matched to

Ring topology is a natural match for SONET–based TDM networks that constitute the bulk of existing metro network
infrastructure. However, there are well–known disadvantages to using SONET for transporting data traffic (or point–to–point
SONET data solutions, like Packet over SONET [POS]). SONET was designed for point–to–point, circuit–switched
applications (e.g. voice traffic), and most of limitations stem from these origins. Here are some of the disadvantages of using
SONET Rings for data transport: 2.1.1 Fixed Circuits: SONET provisions point–to–point circuits between ring nodes. Each
circuit is allocated a fixed amount of bandwidth that is wasted when not used. For the SONET network that is used for access
in Figure 2 (left), each node on the ring is allocated only one quarter of the ring's total bandwidth (say, OC–3 each on an OC–
12 ring). That fixed allocation puts a limit on the maximum burst traffic data transfer rate between endpoints. This is a
disadvantage for data traffic, which is inherently bursty. Department Of Computer Engineering, MCERC, Nashik. Resilient
Packet Ring Technology 4 2.1.2 Waste of Bandwidth for Meshing: If the network design calls for a logical mesh, (right), the
network designer must divide the OC–12 of ring bandwidth into 10 provisioned circuits. Provisioning the circuits necessary to
create a logical mesh over a SONET Ring is not only difficult but also results in extremely inefficient use of ring bandwidth.

Obviously, we may utilize PVST or MST to give an unpleasant sharing of burden by part the crossing tree inclinations for
distinctive VLANs, however the outline still doesn't change generally speaking. I've discussed this in East West and North

that implies squandered power, space and cooling (which cost more than the gear itself). When you move to a Layer 2

The Ieee 802 Standard
Introduction
Under the IEEE 802 standard, each one system interface gadget (counting system cards in machines, versatile Wi–Fi–
empowered gadgets, and in addition individual ports in scaffolds or switches) ought to have an all–around extraordinary 48 bit
MAC address. Pieces of locations ought to be bought by an association to be allotted to the gadgets that association produces.
On the other hand, in a few cases a gadget might not have an internationally extraordinary MAC address. A few purposes
behind this include:
 Counterfeiters don 't pay for MAC addresses.
 Low–expense system card makers may be allocating their cards arbitrarily created MAC addresses.
 Users or framework chairmen might briefly dole out their gadgets subjective MAC addresses through programming.
Consequently, two or more gadgets may have the same MAC address. This turns into an issue if the gadgets with the same
MAC location are on the same telecast space (e.g. layer 2 system). On the off chance that the gadgets are not on the same show
space, then no issues emerge, since MAC locations are not sent through switches in layer 3 of the OSI model.
This task assesses the obliged number of aggregate MAC addresses seen (i.e. example size) important to discover MAC
location clashes or deceitful MAC addresses for three unique circumstances:
 A system interface gadget supplier takes an unallocated square of MAC locations from the IEEE.
 Devices on provincially directed telecast spaces produce their

Carlson Shared Services (CSS) uses a centralized data processing model to meet business operational requirements. The central
computing environment includes an IBM mainframe, over 50 networked servers from Hewlett–Packard and Sun
Microsystems. In this centralized data processing unit all the servers and the mainframe had their separate disc storage. This
dispersed data storage scheme had the advantage of responsiveness; that is, the access time from the server to its data was
minimal. However, the data management cost was very high. There had to be backup procedures for the storage on each server,
as well as management controls to reconcile data distributed throughout the system. RapidInsight framework enable
organizations to integrate real–time, streaming data, to gain real–time actionable insights, integrate and harmonize data from

Google fiber is a project to build an incredibly fast and reliable internet network infrastructure using fiber–optic
communication. The project started in Kansas City, Kansas; Kansas City, Missouri; North Kansas City, Missouri; Austin, Texas
and Provo, Utah, San Jose California and a few other states. The initial locations were chosen following a competitive selection
process. Over 1,100 communities applied to be the first recipient of the fiber optic technology. On March 30, 2011, Google
announced that Kansas City, Kansas will be the first community where the new network would be deployed. What is "fiber"? If
you 're thinking of dietary needs, you would be just a bit off. "Fiber" is short for Fiber–optic communication. It 's the
transmitting of information from place to place through pulsing light. The cabling is comprised of 100 or more incredibly thin
strands of glass, known as optical fibers. Essentially, data and other forms of signals are beamed around through the glass and
formed on the other side. This is different from standard copper transmission, which uses electrical signals down the copper
cabling to communicate. After building an infrastructure of the network in July 2012, Google announced pricing for Google

1. Introduction Telecommunications is the electronic transmission of signals used for communication sent via means of
telephone, radio, and television. The importance of telecommunication in business is that it removes delays created by time and
distance. With the proper setup it is possible for a company to communicate with any business and affiliates quickly just about
anywhere in the world. To fully understand telecommunications it is important to understand the characteristics of
telecommunication, network types, and the medium used in telecommunications. 2. Abstract Basic telecommunication
characteristics are the medium that carries transmitted messages from point 'A' to point 'B'. There is the simplex channel which
is a communications channel that transmits data in one direction only, this particular channel is not advantages' for business
due to its one way nature. There is the half–duplex channel which can move that data to multiple locations, however it cannot
move them all at the same time, in a company where speed is needed this may not be the best. Then there is the full–duplex
channel which is similar to having two simplex channels, this one permits data to go both ways and multiple flows to move at
the same time. A fourth option is broadband, which is communication channel bandwidth, and in general broadband simply
means that it can move data and information at high speeds, in recent times the larger the business the more bandwidth is
needed to keep

An argument can be made that costs of newer technology will decrease significantly over time and will allow XYZ hospital to
take advantage of these technologies at lower prices.
PROBLEM STATEMENT
The problem is that XYZ hospital has identified the need for telemedicine and electronic health record management
capabilities but hasn 't been able to convey the costs and risks associated with implementing an information system and
network infrastructure upgrade. This is a problem because the current and projected budget will possibly limit funding for
equipment and development of a new system.
PURPOSE STATEMENT
The purpose of this feasibility study was to examine the risks associated with the network and information system and
compared it to upgrading the current infrastructure. The information produced from this research helped XYZ hospital convey
the strengths, weaknesses, and impacts on choosing a new networking and information system infrastructure. This is important
because it will give the hospital the information it needs to help prioritize projects that will allow the–the hospital to continue
to have a competitive edge in providing quality patient care and treatment through the use of technology.

through the hubs introduce in the middle of the source and the goal hubs. For overseeing topology, a different focal server is
not required. (UKESSAYS, 2015) CONS If any hub in the system falls flat, it influences the stream of information exchange
and furthermore any adjustment in the system influences the execution of the system. STAR TOPOLOGY Pros Separation of
system gadgets is accomplished in this star topology. The operation of information transmission is easier because of its
tendency of centralization. CONS The fundamental usefulness of the system gadgets in this topology is accomplished by the
focal center point. On the off chance that the focal center point comes up short the information move in the entire system gets
influenced. (UKESSAYS, 2015) I would prefer using the Bus Topology It is used for small businesses or for homes and its

Introduction
The old generation of electrical power grid has taken care of our needs in the past. However, as our world progress
technologically, so do the expectations from different infrastructures around us. Smart grid is an initiative to completely
restructure the electrical power grid to meet the current and future requirements of its clients. Upgrading our electrical power
grid could bring novel security vulnerabilities into the system. Thus, security is one of the key parts in smart grid technology.
Smart grid technology also puts more reliability demands on WAN (wide area network) infrastructures. [1]
A smart grid is an intelligent electricity network that integrates the actions of all users connected to it and makes use of
innovative information, control, and communication technologies to save energy, cut cost, and raise reliability and
transparency. The smart grid is an upgrade to the current electrical power structure. Meaning, on top of the functionality of our
existing power system, it has upgraded with some novel specifications. These new features adds more vulnerability to the
system. [2]
Smart grid is mainly composed of six basic systems: power generation system, distribution system, transmission network, data
management and processing system, smart metering system, and customer information system. The network architecture of
smart grid

Week 3 Homework
1. When was the first major standard describing a structured cabling system released?
c. 1995
2. Why is balance an issue in UTP cables, and what is TCL?
i. The balance or symmetry of the signal over the wire pairs helps minimize unwanted leakage of the signal. ii. TCL –
Transverse Conversion Loss – The TCL measurement is obtained by applying a common–mode signal to the input and
measuring the differential signal level on the output. a. TCL is sometimes called LCL (Longitudinal Conversion Loss). The
ELTCLT value (expressed in dB) is the difference between the TCTL and the differential mode insertion loss of the pair being
measured. TCTL is the loss from a balanced ... Show more content on Helpwriting.net ...
18. What is the data rate for gigabit Ethernet? i. 1000Mbps (802.3z)
19. What is a benefit of using shielded twisted–pair cabling? i. Cable with the addition of a shield is called shielded twisted–
pair (STP) cable. The addition of this shield reduces the potential for electromagnetic interference (EMI) as long as the shield
is grounded. a. EMI originates from devices such as motors and power lines, and from some lighting devices such as
fluorescent lights.20.
20. Which cable, UTP or STP, is preferred by the industry? i. Industry testing on STP cable has shown that the addition of a
shield does increase the usable bandwidth of the cable by increasing the noise rejection between each of the wire pairs.
However, the tests have shown that there is not a significant advantage of placing a shield over a properly installed 4pair 100–
ohm UTP cable. ii. Most manufacturers are recommending the use of UTP cable for cabling computer networks except for very
noisy environments.
