Due to the convergence evolution, it is expected that the trend of progressive information
technologies will focus more on mobile and widespread media convergence and new services to
come.[3]
Broadband Services [WINNIE]
As the basis for enabling multimedia communication, broadband services naturally calls for media
convergence that will be based on packet transport to promote the integration of various media on
different behaviors. A lead to a demand for similar services in mobile communication environment
is expected to increase with the growth in broadband services like cable, DSL, optical fiber access
systems and office or home LANs. 4G service application characteristics will likely enable
broadband service to be low cost, high coverage of wide area, and wide variety of service
capabilities. [4]
Interactive BCN (All–IP) with Home Networking, Telemetric, Sensor–Network Services [WINNIE]

However, the studies reveal inconsistent results as to whether both constructs always determine
security behavior (Liang & Xue, 2010). Woon et al. (2005) indicate that perceived severity
determines whether individuals take security measures to protect their home wireless network

Safa et al. (2016) defined collaboration as a recursive process, where people, teams, or organizations
work together to perform a task or accomplish a goal. Hence, information security collaboration can
assist in distribution and sharing of information security knowledge among users, as highlighted by
Ahmad, Hadgkiss, and Ruighaver (2012). Similarly, Feledi, Fenz, & Lechner, (2013) indicated that
collaboration can be applied in the form of submitting, commenting on, and peer–reviewing the
knowledge shared, while Mace, Parkin, and Moorsel (2010) suggested that collaboration is a key
benefit for identifying features to assess information security threats also that collaboration can
create valuable knowledge in information security domain as it assist users to understand and extend
their information about security breaches. Bernard (2007) found that information security

Wireless Network Technology : Wimax
Wireless Network Technology: WiMAX This article focuses on one of the most used wireless
technologies that uses wireless connections of data that avoids expensive process of cables at home:
WiMAX. WiMAX stands for Worldwide Interoperability for Microwave Access. Being a faster
version of Wi fi, this technology promises speed and large area coverage. It has been successfully
proven to deliver the services to the customers (both residential and commercial) economically.
WiMAX has the capacity to serve high rates of data that might reach up to 74 Mbps when used a
wide spectrum of 20 MHz This has added to its brand value that attracts abound customers. WiMAX
falls under the category of MAN technology that came into existence in June 2001. However, the
updated version came in 2011 that allowed this technology to provide up to 1 Gbits for particular
stations.
There are two types of Wireless services provided by WiMAX:
1. Non–line–of–sight: The service of Non–of–Line–of Sign resembles Wi Fi service that uses quite
low frequency array that ranges from 2 GHz to 11 GHz.
2. Line–of–sight. It has a higher frequency up to 66 GHz that allows eradicate the errors quite a bit
with a larger capacity of data.

Wireless Sensor Networks And Technology Constraints
Wireless Sensor Networks (WSNs) present universally and growing rapidly due to its unique
features, such as their less weight, cheap, and wireless nature. However, due to its highly
constrained computational and energy resources this network is exposed to numerous attacks that
affect its security. So, it is important to address these security issues from the beginning of the
system design. but, due to inherent resource and computing constraints, security in sensor networks
poses diverse challenges than traditional network security so, designing security protocols for all
layers in this kind of a network becomes an compelling need. In this paper, we studied several
existing WSN security protocols and data link layer security algorithms, which ensures a safe
communication link between neighboring nodes by supervising the medium access and handling the
errors. The purpose of this paper is Not Only Studying and explaining the strength and limitations of
the existing energy efficient security protocols of the data link layer but also and determine the
crucial security requirements which should be taken into consideration for design of future of data
link security protocols. I.INTRODUCTION Sensor network got tremendous focus due to its less
cost and small size and which can be placed anywhere. A sensor network consists of number of
sensor nodes dispersed in a specific geographical area. These sensor nodes communicate using
wireless transceivers. These networks are widely used

Network Enterprise Technology Command (NETCOM)
The Army Operating Concept describes the network as an important technological focus area
(Perkins, 2014). Therefore, efforts have been made to revolutionize network capabilities, "such as
cloud–enabled networks for mobile operations in austere environments and across wide areas, that
are simple and resilient, anticipating enemy efforts to disrupt communications (Perkins, 2014)." In
addition to modernizing and consolidating the network, Network Enterprise Technology Command
(NETCOM) has developed a plan to regionalize network centers. The project will support the Army
Chief Information Officer's decision to interconnect all Department of Defense networks. However,
there is potential for consolidation and transformation of functions and positions, which may result

The Change Curve model describes four stages most people go through as they adjust to change
(MindTools, n.d.). It is mostly accredited to psychiatrist Elisabeth Kubler–Ross, but changes have
been made to the model over the years. The employees first reaction to the change was surprise,
which has been identified as stage one of the Change Curve. When the realization of the change set
in, there was a tendency to react negatively, which is the transition point into stage two of the
Change Curve. It is in the best interest of those in stage two to move on into stage three because that
is "where pessimism and resistance give way to some optimism and acceptance" (MindTools, n.d.).
In the final stage of the Change Curve, individuals are able to accept the change and embrace them.

Virtual Private Network ( Vpn ) Technology
Abstract:
A virtual private network (VPN) technology creates an encrypted connection over a network. VPN
is useful to exchange information between offices securely. VPN has advantages over traditional
private networks and dedicated links. Tunneling techniques are used to implement VPN. This paper
describes the various tunneling technologies like, IPSec, PPTP, GRE and L2TP used in virtual
private network. It concludes by comparing these technologies and their use for given selection
criteria.
I. Introduction:
A virtual private network enables us to send data between machines across different networks. VPN
has all the characteristics of a private network. It allows only authorized users to access network
related services and resources. ... Show more content on Helpwriting.net ...
The data being sent is encrypted for confidentiality. The packets over the link are indecipherable
without the encryption keys. If one of the router is destroyed in the communication link it
automatically rebuilds a new communication path so the communication gets rerouted through a
new path.
The VPN connection across the Internet logically operates as a wide area network (WAN) link
between the two sides.
Advantages of VPN:
VPN has several advantages over the dial–up networks and leased lines. The capacity of these lines
is available at all times but fixed and flexible. The traffic on these private networks belong only to
the company deploying the network. There is an assured level of performance but it comes with a
very high price [4].
The traditional private networks are expensive to deploy and plan. The cost is extremely high when
it involves international locations. Further, the dedicated links take time to install and activate the
link. Therefore, using VPN utilizes the ubiquity of the Internet and convenience for dynamic
building and maintenance [3]. Moreover VPN facilitates an agile IT infrastructure. VPN also
supports a mobile workforce a reliable authentication mechanism is supported by VPN to provide
easy access to Internet from anywhere using available access media including analog modems,
ISDN, cable modems, ISDN and DSL at significantly lower cost.
Types of VPN connections:
There are two types of VPN

Network Technology Case Study
Phase Two Phase one discussed the employee required hardware and software to do daily job
request. Phase two discusses how the user PCs and laptops connect with each other and the internet.
Without the interconnections, each laptop and PC is a standalone unit, only when a network
topology is in place will all the network resources be able to contact each other. In addition to the
network cards discussed in phase one, phase two justifies requirements for future enterprise
sustainability.
Cabling

Cat–6 cabling is becoming more economical; this is comparing cost–to–bandwidth capabilities at
about a 20 percent difference (Cat5e vs Cat6, ... Show more content on Helpwriting.net ...
In addition, the logical topology is also set in a star format for direct communications; this is unlike
mesh topology where all communication is broadcasted to all other network attached equipment.
With both a physical and logical star topology, network bandwidth is decreased as network
communications are point–to–point. Decreased network bandwidth increases overall productivity as
network related work is not hampered by slow network traffic.
IPv6 and Address Pool More sooner than later the internet will transition to IPv6 rather than the
current IPv4 standard; this is partially due to very few IPv4 network address available (Haugh,
2012). Many large companies are already using the IPv6 internet protocol and using it now will
prevent having to reengineer the network at a later timeframe (Wong, 2011). Even though the local
ISP may require IPv4, in the short term, that can be overcome by using IPv4 and IPv6 dual stack
tunneling (Beverly, 2015). This allows external IPv4 address conversion to IPv6 with the
configuration of the internet facing network address translating (NAT) router. Although the ISP
provides the corporate network with the IPv4 Class C IPv4 address, it will also provide a block of
IPv6 addresses for all the network attached devices in the local area network. To maintain
communication with the internet, the NAT router will provide the appropriate dual stack translations

INTRODUCTION
1.1BACKGROUND
The need to continuously monitoring physical phenomena has leads to many advances in sensing,
computing and communication technologies. And a new technology evolves which is known as
Wireless Sensor Networks (WSNs). Wireless Sensor Networks are a new kind of distributed
systems that are an integral part of the physical space they inhabit. The massive growth in this
technology has gathered the heed and imagination of many researchers, providing a broad spectrum
of ideas to be implemented in various applications [2].
The grouping of various sensor nodes makeup a huge Wireless Sensor Network (WSN). These
wireless sensor networks are employed in environments where human reach is difficult. The sensor
nodes are small, inexpensive, battery powered devices which are capable of local processing and
wireless communication. These sensors cooperatively work with each other to sense some physical
circumstances and then the information is gathered and processed to get pertinent results. The
information that is gathered is sent to the main location.
Figure 1.1 depicts a typical WSN. Networking unattended sensor nodes are expected to have
significant impact on the efficiency of many military and civil applications such as combat field
surveillance, security and disaster management. These systems process data gathered from multiple
sensors to monitor events in an area of interest. For example, in a disaster management setup, a

(ii) Resource limitations on sensor nodes. (iii) Lack if fixed infrastructure. (iv) High risk of physical
attacks. (v) Unknown network topology prior to deployment. This is why it is tough to secure WSN.
II. TERMS, DEFINITIONS AND NOTATIONS
Terms used in this paper are as follows:
–key: symmetric key which is used to secure communication among two sensor nodes.
–pair–wise key: key which is used to unicast communication between a pair of sensor nodes.
–group–wise key: key which is used to secure multicast communication among a group of sensor
nodes .
–network–wise key: key which is used to secure broadcast messages.
III. NETWORK MODELS AND SECURITY REQUIREMENTS OF WSN
There are generally 2 types of architectures in WSNs. (i) Hierarchical and (ii) Distributed. In a
Hierarchical WSN, A base station is a gateway to another network with some other base station to a
data processing and storage center, or a human interface node point. Base point takes data from
sensors send it to processing unit and that data is sent to the human interface node point. Therefore,
base stations are used as key distribution centers as they are connected every other node in network.
Sensor nodes form a dense network in form of clusters where a cluster of sensors lying in a specific
area may provide similar or close readings of data. Not all node gets the power from power unit few
sensor nodes depend on the ad hoc communication to reach base stations.

A network is a group of computers and other devices connected by some type transmission media.
There are various kind of network available nowadays. A network can be as small as two computer
connected by a cable at home or larger like several thousand computer connected worldwide via
cable lines, phone lines, and cellular links. The use of networks has lots of advantages. Networks
enable multiple users to share devices and data. For example, instead of buying 20 printers for 20
people, a company can buy one printer and have 20 people share it over a network. Here are five
technologies that uses network: scanner, printer, Bluetooth, ... Show more content on

There are some computers that have Bluetooth network to allow printing from smartphones, tablets,
etc. All recent version of Microsoft windows uses File and Printer Sharing feature to allow printer
connected to one PC to share with other PCs over local network. Another way network printing is
cloud printing. Cloud printing can be done over internet connected computers and phones to a
remote printer. Off course this requires a printer to be connected with internet network.
Another device that works on by using network is Bluetooth. Everyone is failure with Bluetooth. It
is pretty much in every cellphone, computer, cars, and etc. the Bluetooth works by transmitting low
frequency radio waves of about of 2.45 gigahertz. There are other devices that uses the same
frequency like a baby monitor. the Bluetooth is designed such way that it won't interfere with other
devices using the same frequency. Bluetooth send very low and weak signals of about 1 milliwatt to
avoid interference. A Bluetooth can connect to up to eight devices in one time. Bluetooth uses a
technique called spread–spectrum frequency hopping. The spread–spectrum frequency hopping
makes the Bluetooth rare for more than one device to be transmitting on the same frequency at the
same time. in this techniques Bluetooth uses 79 random frequencies within the range and changes
from one to frequency to another in a regular basis. The Bluetooth transmitters changes frequency

A LAN network (Local Area Network) is an establishment created when clients or devices such as
computers and phones etc. with the right networking specifications allowing them to be connected
with each other using a common connecion such as Ethernet or wireless. This establishment allows
the sharing of resources from the device through the network and to the desired destination such as
another device e.g. Mobile phone, pc, tablet etc. all locally within the network by Ethernet etc. In
this scenario the LAN network is used for gaming where two computers connected to the same
network are trying to connect with each other to allow an established connection between the two
allowing data to be shared, effectively creating a game server. A user will mainly use a specific LAN
to share data between clients by pairing them together.
Ethernet is the most commonly used LAN technology. It is used to transmit data locally from the

At this point, the research would usually discuss the repercussions of the RIS policies with regards
to firm involvement and actions. However, Catalonia has historically been severely lacking in
resources and, as a result, levels of innovation are quite low. This lack of resources is what is usually
attributed to the reason for why the Catalan government is so willing to pursue action on developing
a strong supporting network for science and technology. However, even today the capacity for
production in those areas are still weak. R&D expenditures for Catalonia are at 1.35% in 2005 are
much lower than the OECD average of 2.25% (Segarra–Blasco et al 2008). This is directly related

The ICT is particularly notable, however, due to its history. It was produced in the Valles
Technology Park in the 1980s but was soon dissolved due to extreme lack of interest in the
industrial sector. It has since been restored but the institution is so recent that no significant
knowledge has been produced on the subject.
Basic Research Basic research is restricted to public research centres such as universities. However,
one of the most active and internationalized types of public research centre are CSIC centres in
Catalonia, of which nine are dedicated to basic research. These centres were also heavily affected by
the court's delay in regional and national boundaries. However, support for these centres has since
strengthened with agreements with the Catalan government in order to provide more integration
with the RIS. With regards to universities, these institutions were traditionally almost entirely
created for teaching instead of research. Around the new millennium however, a trend began to
change this feature. New resources and regulatory measures have been initiated by the national and
Catalan governments, giving rise to a new efforts at research and connections with industrial
partners.
Applied Research The bifurcation between applied and basic research can be found in R&D
expenditure data. Public expenditure growth has been rapid in both absolute and relative terms,
especially between the mid–1980s to early 1990s

Network Attacks Using New And Effective Modern Day...
The primary objective of this project is to detect and mitigate various network attacks using new and
effective modern day technologies. 1) Software Defined Networking (SDN) is one of the start of art
technology that will be used in this project to mitigate the attacks like Denial of Service attacks. 2)
It will also help in controlling the data and control plane of the networking devices, which will
enable more options to enhance the security. Implementation of security measures in SDN can free a
network from several network attacks like Denial of Service (DoS) attacks. Another point to be
noted is that, if an administrator had to upgrade the security measures in a traditional network, he
would have to configure all the networking equipment separately with the required security
measures. If the administrator needs to make any future changes to the network, he would have to
again have to update on each and every device separately. This method demands a lot of resources

A SURVEY ON VIRTUAL PRIVATE NETWORK SECURITY AND ITS TECHNOLOGY
Abstract
Virtual personal Network (VPN) may be a communication network that provides secure knowledge
transmission in an unsecured or public network by mistreatment any combination of technologies. A
virtual association is created across the users who are geographically spread and networks over a
shared or public network, just like the internet. even supposing the info is transmitted during a
public network, VPN provides a bearing as if the info is transmitted through personal connection.
This paper provides a survey report on VPN security and its technologies. Keywords: Tunneling;

knowledge encapsulation is finished by wrapping the info with a header, that provides routing data.
This method is named as tunneling. to supply confidentiality to the encapsulated knowledge, the
info is secured by encoding. once knowledge reaches a tunnel finish purpose, the encapsulated
knowledge is decrypted and forwarded to its final destination purpose. VPN permits organizations
to attach to their branch offices or to alternative firms over a public network whereas maintaining
secure communications. The VPN association across the web logically operates as a good space
network (WAN) link between the sites. The secure association across the web seems to the user as
{a personal|a personal|a non–public} network communication–despite the actual fact that this
communication happens over a public internetwork– thus the name virtual private network. 2. VPN

Is Communication The Only Good Contribution?
Is communication the only good contribution to this new era of technology? Thanks to new
technologies people can stay more connected than ever using the endless capabilities of their
smartphones. However, it seems that in this new era, the more connected we are, the more
disconnected we become. Nowadays people seem to be more reluctant from interpersonal
interaction. Whether going to parties, dining with friends or even commuting, people tend to
disconnect from reality. Also, when using their headphones, reading on their tablets, playing video
games on their phones or just looking at them for hours, people are becoming now more and more
distant from each other. Technology is making individuals less interested in socializing and more
isolated by keeping them distracted and addicted from what has significant meaning in their lives;
and it can also cause damage to their health. First, Social media such as Facebook, Twitter or
Instagram have made people less interested in face–to–face interaction. People can stay for
prolonged periods of hours just looking or checking what is happening in the media, seeing their
friend's pictures or tweeting about any topic on their phones. In fact, according to a study by
Chicago University, it is much harder to resist the use of social media than the desire of smoking or
having sexual intercourses (Meikle, 2012). It is true that improving relationships and making new
friends are good advantages of social networks (Solis, 2011). However,

GAI is a financial institute located in Canada, the United States, and Mexico. It is specialized in
financial management, loan application approval, wholesale loan processing, and investment of
money for their customers. The GAI employs over 1,600 employees and has been growing
consistently for nearly six years because, its management strategy has been built on scaling
operational performance through automation and technological innovation. However, the GIA has
experienced several cyber–attacks from outsiders over the past a few years ago. This attack has
conducted the loss of its confidentiality, integrity, and availability for several days, the loss of its
reputations, and mostly the loss of its customer data confidentiality. To secure the GAI's network
system, a lot of issues have to be addressed. This paper will cover the identification and description
of authentication technology and network security issues, list all access points, it will design a
secure authentication technology and network security, list all known vulnerabilities, address
concern over the mobile security and design a secure mobile computing, identify wireless
vulnerabilities and recommend what safeguards, and finally, design a cloud computing environment
for GAI. Because GAI is a financial institution, to secure its facility, a top secret clearance have to
be required for everyone who enter its network or facility. GAI's Computer Security manager

that early exposure to technology has its benefits. The Digital Parent Trap is an article written by
Eliana Dockterman published in 2013. In this article, Dockterman talks about how technology plays
a valuable part in American schools and how it affects these families. Dockterman shares multiple
points that support her argument, but she also talks about how parents feel about the technology that

Dockterman provides sources that connect with social networks. She says , "new research suggest
that social–networking sites offer learning opportunities.. Kids can engage with communities of

these social networks can improve these students lives by connecting them to more people who have
similar interests. This quote supports her argument because it makes the reader feel that they can let
their children use the technology so they can connect to more people who have the same interest or
it can make the child learn something new. In the beginning of the article Dockterman is writing
about how parents view technology and its role in the school system. She introduces various sources
such as the Grunwald Associates to say , "Barely half of U.S. parents agree that mobile technology
is should play a more prominent role in school"(Dockterman 1). Doctorman persuades the reader by
providing information that shows how many people think technology is important and by providing
a reliable source. She uses ethos by providing a credible source. This source provides a fact that can

Apple scab is caused by a fungal pathogen (Venturia Inaequalis), and can result in severe defoliation
of apple trees if poorly managed. The hills of Thanedar–Kotgarh near Shimla, were found to be
ideal for apple growing, but has expanded through the state, growing from 360 hectares in the 1950s
to more than 150,000 hectares in 2014. Apple production contributes a major portion in Indian
economy [5]. Powdery mildew in Kutki is a very dangerous disease. It is caused by the fungus
Erysiphe necator (formerly Uncinulanecator). In India, it is found in the Himalayan region of
Kashmir to Sikkim and is highly useful in digestive problems, asthma, liver damage, wound healing,
vitiligo etc. But it is one of the endangered species so it needs to be protected from diseases [6]. In
order to protect these two major crops from diseases we developed a prototype system for plant
protection and pest management using a real time Wireless Sensor Network, which will be installed
in Mashobra, Shimla for Apple and IHBT, Palampur for Kutki.

If it's a large network consisting of so many networking devices, then it would be difficult to
configure each and every device with these security measures as it takes a lot of time to do so.
Further more, many network attacks are taking shape these days and their effects on the network are
unpredictable. So if a new attack comes and if a security measure is developed against the attack,
then it should be updated in each and every network device in a network, which will be a very
tedious job to do. This is the current trend running in the networking environment. In our project we
are implementing these security measures over SDN, as it provides a centralized controller for the
network. If we just configure these security measures in the centralized controller, then the entire
network, which is under the control of this particular controller, can be secured. Thus it saves a lot
of time and effort. And if a new network attack comes into the network, then the security measure
against this network attack can be configured inside the controller, so that it can be applied to the
whole network, which is under the control of this controller instead of changing each and every
networking device configuration in a network. Software Defined Networks (SDN), as we utilize this

The peer–to–peer network is a type of network that does not use dedicated network servers for
logging in users or providing secure access to network resources. This type of network lets clients
share resources and have access to whatever they are sharing (i.e. printers). This type of network
would be an excellent choice for small businesses with less than 10 employees because it enables
them to share resources from their computer. These resources can be files, printers, and Internet
connections. This type of network is a cost effective solution due to having less management or
support from outside experts. This type of network setup and usage is simple, but it is less secure
and be vulnerable to security breaches. The second network is the client–server network, which does
use a dedicated server. It uses the dedicated server to centralize users and manage group accounts. In
a client–server network, the server controls access to the resources to the other computers on the
network and clients do not talk directly to one another (West, Dean, & Andrews, 2015). Users at a
client or workstation log on to the server using their own accounts and passwords. The users can
only access resources that they were given permission for. This type of network is used for larger
businesses to meet complex and challenging needs. This type of network has the potential to grow
as the business grows. But, this can have a significant effect on cost

Network Technology, Structure, And Protocols
Introduction
This paper is about basic network technology, structure, and protocols. This paper will cover the
module question "Discuss how the structure of the TCP IP framework has enabled the expansion of
the Internet into a worldwide network. Discuss issues with this network. Is it big enough? Are
enough IP addresses for all? What is being done under IPV6? This will be accomplished by
addressing the crore topics as well as how IP started to grow, the issues with the network in regards
to technological limitations as well as the different types of vulnerabilities and attacks. This paper
will conclude with a summary.
Structure of TCP IP and expansion In the beginning, the internet was without form. It was in the
early phases with agencies such as DARPA and educational institutes that we laying the ground for
what the internet turned into. However, as the internet grew, not everyone used the same
communication method so there had to be gateways installed on the border of networks in order to
translate one type of protocol into another (Bellovin, S. M.). This was not good so the advent of
TCP IP was constructed. This allowed for uniformed communication and thus brought on the rapid
expansion of the internet. The internet follows the open systems interconnect model (OSI)
developed by Charles Bachman at Honeywell Information Services, this consists of seven layers. 1.
The physical layer, this includes both wired and wireless forms of communication. An Ethernet

Emerging Network Technologies : Server Virtualisation
Emerging Network Technologies Server virtualisation Explanation Server virtualisation isn't
something that's necessarily new, though it require a hat tip nonetheless. Virtualisation works by
splitting up a physical server into multiple different virtual servers, with each server's resources
being masked from the end point user. It is commonly used by businesses to cut their costs,
especially in the realm of web–hosting where a hosting provider will use one powerful server – But
cut it into hundreds of smaller servers which can be auctioned off at a cut–throat price to consumers.
How does it affect the bank; to what impact? Server virtualisation would be a major step forward for
the bank, especially seeing as the current network has multiple issues when supporting users. This
may be due to an incorrect network topology being used, however the scenario hasn't outlined what
topology is currently being used – So any comment on it is purely conjecture. Server virtualisation
would enable the bank to split its struggling server up into multiple pieces, each of these instances
would be separate from one–another in the fact that they would each be reboot–able individually;
limiting downtime to other employees tied into the same network – Providing far superior fault
tolerance; no longer is the system one giant domino, but rather many smaller dominos which cause
nothing more than a drop in the ocean. Greater storage capacity Explanation Phone memory, for
example, has expanded

The term 'VPN' has no standard interpretation. Different networking specialists and different
organisations may understand it in different ways. Historically, the term was first introduced by
telephone companies. The main feature of a telephone VPN is that it can provide users from an
organisation which uses a public provider's telephone service instead of its own private PBX with
something very close to PBX functionality (commonly known as Centrex, and popular in North
America). For example, they can dial using convenient private (usually short) numbers; certain
phones can be fully or partly isolated from the public telephone network; and users can use PBX–
style telephone services like call forwarding, call rerouting, voice mail etc. For data networks the
term came to be used later, at first mainly for services which provide more security than the
standard Internet service due to user data encryption. However, there are also services that do not
encrypt user data but create logical channels for users within public data networks and provide
controllable connectivity between VPN users and with the outside world. (Some of these elements

LinkedIn has helped revolutionize how job searching and hiring is conducted. Employers can now
view a complete profile of you, your work experience, and your professional career. The profile you
create is open for everyone to see, which can be both helpful or harmful depending on what you
choose to put on display. Essentially, LinkedIn is your resume and profile online for all to see.
While job–search sites do this as well, LinkedIn saves companies thousands of dollars by displaying
all applicants' information for free. With LinkedIn, you have access to hiring, reference checking,
customer leads, affiliations, open jobs, and international contacts. Hiring has never been more
accessible, as you are now able to "connect to references, view a list of people with similar
backgrounds, identify people in your industry or even specific companies." Reference checking, a
process that could take a longer period of time to complete, is now readily available for companies
to view and access almost immediately. Rather than becoming bogged down by cold calls, LinkedIn
offers potential customer leads, which has resulted in a salesperson being able to identify "potential
customer, find who else in their network has contacts within the company or better yet knows the
person your salesperson wants to meet and ask for an introduction." Your affiliations that you have

Initial Development Of Wireless Technology ( 3G / 4G...
1.1 INTRODUCTION
The aim of third and fourth generation (3G/4G) mobile networks is to provide users with high data
rates, and to provide a wider range of services, such as voice communications, videophones, and
high speed Internet access. A common challenge in a wireless system design is to overcome the
e ects of the wireless channel, which have multiple transmission paths and di erent delays. OFDM
has a promising future as a new technology in several next generation wireless communication
systems. The OFDM systems ability to combat the e ects of multipath propagation with a relatively
simple receiver structure made it the modulation of choice for some of the most prominent wireless
technologies such as the IEEE 802.11 wireless local area ... Show more content on Helpwriting.net
...
These systems require analog oscillator and lter of much wider bandwidth and sharp cut–o .
Therefore, the concept of OFDM was not gained so much attention or popularity because of the
diculty in sub–carrier recovery without inter–sub–carrier interference by means of analog lters.
Due to this reason only, a number of studies in the
1960s were dedicated for MCM employing overlapped band–limited orthogonal signals [12] [10]
[13]. In the year 1967, B. R. Saltzberg suggested a MCM system employing Orthogonal time–
staggered Quadrature Amplitude Modulation
(O–QAM) on the carriers [12]. The concept of MCM scheme employing timelimited orthogonal
signals, which is similar to OFDM, was rst given by H. F.
Marmuth [14] in 1960.
A major breakthrough in the history of OFDM came in 1971 when Weinstein and Ebert used
Discrete Fourier Transform (DFT) to perform baseband modulation and demodulation which
eliminated the need of bank of subcarrier oscillators thus making the operation ecient and simpler
[15] [16]. In
1979, after evolutionary growth and development in signal processing and VLSI technologies, high
speed chips can be built around special–purpose hardware performing the large size Fast Fourier
Transform (FFT) (ecient algorithm for
DFT) at a ordable price [17] [18].
All the proposals of OFDM systems used guard spaces in frequency domain and a raised cosine
windowing in time domain to combat

Switching Technology For A Network
Switching Technology
Cassandra Anton
Bellevue University Abstract
Switching is a technology that has been used since the first communication networks were invented.
In order to understand switching, we must first discuss switches. A switch is a device that connects
other devices on a network. Switches can also prevent bad packets from spreading by not
forwarding them on. While switches can be helpful to a network they should not be seen as an
instant fix for network issues. There are many benefits to using network switching in a network. A
switch can break one large network into smaller networks so that the distance limitations are
restarted. By creating the smaller networks traffic is isolated, reducing collisions. It can ... Show

In a full switched network, hubs are not used. Instead, switches are used with a dedicated segment
for every node. In this type of network the switch picks up every transmission before it reaches
another node. Since any segment only reaches a single node, the frame only reaches the intended
recipient. This allows many conversations to happen at the same time. Switching also allows a
network to maintain full–duplex Ethernet, which allows information to travel from node to switch
and switch to node at the same time. Most networks do not exclusively use switches because of the
costs involved with replacing all hubs. A combination of switches and hubs are typically used to
create an efficient and less costly network (Tyson 2001).
When switching on layer 2, there are three important functions that a network administrator should
remember. The first, address learning, is when layer 2 switches retain the source hardware address
and port interface it was received on. It is then entered into a MAC database called a forward/filter
table. The second, forward/filter decisions, is when a switch looks at the destination hardware
address and finds the interface it is on in the filter table. It then chooses the correct exit interface for
it in the MAC database. Finally, loop avoidance. When redundancy creates multiple connections
network loops

The Technology of Computer Networks
Introduction
Computer network – a system used to link PCs or computer equipment (servers, routers, and other
equipment). For data transmission can be used various kinds of electric signals, light signals or
electromagnetic radiation. Computer networks can be classified according to various criteria –
territorial prevalence, type of network topology, etc. One of the criteria – the type of transmission,
the network is divided into wired and wireless.
Wi–Fi – a trademark of Wi–Fi Alliance for wireless networks based on the standard IEEE 802.11.
The acronym Wi–Fi (from the Wireless Fidelity, which can be literally translated as the quality of
the wireless) is currently developing as a family of standards for the transmission of digital data
radio streams. It is still often hears that the wireless network is not secure compared to wired
solutions. At the present stage of Wi–Fi technology's development that is not true. Simply security
needs to be addressed (to design and maintain), as in the case of a wired network.
It has long been known that the defense of any infrastructure is only one method of creating a
protected perimeter is ineffective, as often the most dangerous attacks are caused by factors within
the network. Building a security system Wi–Fi network should take into account all of these factors
in order to come as close to a similar level of security of wired and wireless network segments.
And what, in fact, an attacker can get on the wireless network , set up which

The emmergence of new social networks has been noticed throughout the world, and organizations
have sprung up to address these concerns. There are symposiums of computer professionals
addressing the affect of networks, along with the National Communications Associaton, and in
particular there is an online journal, Connections which is devoted to social network analysis. One
article in this journal discussed the role of networks in matching political media opinions and
perspectives with individuals and their corresponding social groups.The article says that society's
concept of itself has been expanded and fractured by new social networks, and that these social links
can be analyzed to better understand societies inner workings.
Each individual, each social group, possesses a network of opinions on social conflicts that are not
arbitrary but tied to one another to form specific, coherent networks whose ties show a strong
resistance to deformation by external events. Specific networks of opinions on social conflict can be
associated with individuals and social groups, and the network ties show strong resistance to change
over time. There is even the possibility of measuring the resilience of these network ties. (4)
The network ties refered to in this quote are increasingly reliant on information technology, thus the
strength of this technological infrastructure corresponds with the
