For some years, commentators have been predicting the 'convergence' of the Internet and
mobile industries. But what does convergence mean? Is it just about mobile phones providing
Internet access? Will the coming together of two huge industries actually be much more about
collision than convergence? In truth, there are lots of possibilities about what convergence
might mean, such as:
• Internet providers also supply mobile phones - or vice versa, of course.
• The user's mobile phone is replaced with a palmtop computer.
• The mobile Internet leads to a whole range of new applications.

In a prior edition of this book the preface commenced with the paraphrase of
an old adage in an era of evolving local area networking technology: Ethernet
is dead—long live Ethernet!
Although advances in communications technology continue to occur at a
rapid pace, that paraphrase continues to be valid. Within the past decade, the
bandwidth of 10 Mbps Ethernet was advanced by a factor of one thousandwith
the introduction of a series of enhancements to the original Ethernet specification.
First, Fast Ethernet resulted in the bandwidth of Ethernet increasing
by a factor of 10 to 100 Mbps.
This white paper provides a brief tutorial on Ethernet – a family of standards that
defines several well-established 10 Mbps networking technologies and three
newer, high-speed offerings, Fast Ethernet, Gigabit Ethernet, and 10 Gigabit
Ethernet. It is intended for carrier network professionals, experts in the circuitswitched
technologies employed in public switched telephone networks (PSTN)
but often new to Ethernet and data networking.
Wireless sensor nodes are small, embedded computing devices that interface with sensors/
actuators and communicate using short-range wireless transmitters. Such nodes act
autonomously, but cooperatively to form a logical network, in which data packets are routed
hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless
Sensor Network (WSN) comprises of a potentially large set of nodes that may be distributed
over a wide geographical area, indoor or outdoor
Wireless Sensor Networks hold the promise of delivering a smart communication
paradigm which enables setting up an intelligent network capable of handling
applications that evolve from user requirements. With the recent technological
advances of wireless sensor network, it is becoming an integral part of our lives.
However, due to the nature of wireless sensor networks, researchers face new
challenges related to the design of algorithms and protocols.
Be warned that this test is harder than the MCSE or CNE exams. However, it has some overlapping material with the
Networking Technologies exam by Novell or the Networking Essentials exam by Microsoft. I would highly recommend that
you take these exams before even considering the CCNA exam. If you do not have a solid understanding of the essentials
of networking, you will be throwing away $100.
Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as
temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass
their data through the network to a main location or sink where the data can be observed
and analysed. A sink or base station acts likean interface between users and the network.
One can retrieve required information from the network by injecting queries and gathering
results from the sink.
This diagram illustrates the Physical layer (Layer 1) of the OSI model. The Physical layer is responsible for the ultimate transmission of data over network communications media. It operates with data in the form of bits that are sent from the Physical layer of the sending (source) device and received at the Physical layer of the destination device. Ethernet cabling, Token Ring network technology and SCSI all function at the Physical layer of the OSI model. Hubs and other repeaters are standard network devices that function at the Physical layer.
Development of packet-switched data communication networking
technologies has been rapid in recent years, a phenomenon made
possible by the open standardization process and the potential
new territories for intellectual property creation. As a consequence,
new ways of creating services have been devised, bringing more
flexibility as compared to traditional telecommunications schemes.
Welcome to Wireless Home Networking For Dummies. Wireless networking
for personal computers is not really a new idea; it’s been around
for at least five years. The emergence of an industry standard, however, has
caused the use of wireless networking technology to explode.
One of the most appealing things about the current crop of wireless networking
equipment is the ease with which you can set up a home network, but its
reasonable price might be the most attractive aspect of all. Setting up a wireless
home network can be both inexpensive and easy.
