ridiculous of all the buzz surrounding the new MacBook Pro, is now almost a
reality. Light Peak is ready for
release and it is safer to do so tomorrow under the name Thunderbolt
detected in the case of the new model of laptop. </span></i></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">Apart from the fun of pronouncing
the name invocásemos screaming as if some cosmic power, we know from the latest
images Thunderbolt is not a completely new connection port but that is completely integrated in Apple's Mini
DisplayPort with consequences that have not know. Does it? If we take a
look at the patents that have been discovered recently about this, we can find
out a bit about what we might see tomorrow explained in detail by Apple itself. </span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">If we join the little we know about the
specifics, we can get an overview of the capabilities that can have that new
port. Here we go. </span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">

<b><span style="font-size: 18pt;">The expected arrival of a faster port </span></b></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: inherit;">
</span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;"> The arrival of a successor of
the currently used ports, USB 2.0 and FireWire, seemed far away despite
warnings in the form of rumors that reached us and promised their marketing in
a short time . The tagline of "Yes, come, and it will Light Peak" has
been used extensively to demonstrate exaggerated rumors not so long ago. But
that, by the evidence, ends tomorrow.</span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">
</span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">Let's start with the specifications.
Originally designed for use with optical fiber but made </span><span style="font-size: 12pt;"></span><span style="font-size: 12pt;">from copper to speed their arrival, Light Peak promises speeds of 10 Gigabits per second in
the short term and 100 Gigabits per second in the long run in both
directions simultaneously. For comparison, the Firewire 800 port achieves
speeds of 0.8 gigabits per second. </span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">But how will it behave in the Mini
Display Port? When I saw how it was implemented I could not help remembering
the outline of the rumor that we saw late last year: </span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: inherit;">
</span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<b><span style="font-size: 18pt;">A patent to rule them all </span></b></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: inherit;">
</span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">Not exactly the same because the
scheme fuses including electric cable, but we could find a similar concept.
Thunderbolt is fused to the mini DisplayPort port, which suggests an adapter cable to take advantage
of new technology and at the same time to connect a screen. </span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">Why of course ... what will happen
now with peripherals? Will he drives Thunderbolt? Camcorders Thunderbolt
"? Has not heard of them, and USB 3.0 will have gained ground with the
first compatible peripherals that interface. What I scale is the
"Thunderbolt high speed i / o" photographed furtively Thunderbolt does not speak of
"port", but Thunderbolt i / o. It sounds more like an improved
system connectivity and ports of the Mac interface is not a new independent
connection, right? </span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">Knowing that it is connected to the
Mini DisplayPort, looking to a new version of that port with the addition of a
new interface through which data can be passed in turn to a series of adapters
might work faster. Who knows, maybe we find a way to improve transfer rates of
our existing peripherals, with a high price but having to purchase more adapters.</span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;"> </span></div>
<div style="text-align: justify;">
<span style="font-family: inherit;">
</span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<b><span style="font-size: 18pt;">The bit rate is what matters </span></b></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: inherit;">
</span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">That said sospesa yet the
possibility of a new connection interface. how much information passes
through a data cable when using a screen like ... say the LED Cinema Display 27
" ? It seems silly, but if Thunderbolt anchu will share your bandwidth
with other devices we can find surprises. I've been talking with Frikjan ,
friend and reader of this blog with experience in these matters, and the data
is obvious: trying 3686400 pixels with peak light interface occupy almost the
10 Gigabits per second transfer of the cable (2650 pixels x 1440 pixels x 30
bits per pixel x 60 Hz are more than 8 gigabits per second, and the Light Peak
interface uses more bandwidth). If we have to connect more peripherals, it will not be much available bandwidth for all
data that have to be transferred. </span></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<br /></div>
<div class="MsoNormal" style="font-family: inherit; line-height: normal; text-align: justify;">
<span style="font-size: 12pt;">Unless, of course, that Intel and
Apple have thought about this and have created a system whereby separate data transfer screen data
peripherals can be connected through adapters. Anyway, knowing it is a
laptop does not always have a screen connected to it and have incredible
transfer speeds that are compatible peripherals. </span></div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2138855673652777881.post-82766157199597021172011-06-07T11:34:00.000+05:302011-06-07T13:10:28.996+05:30What is HSDPA and HSUPA network technology?<div style="background-color: white; font-family: inherit;">

<br />
<i>ATMs,
originally called ATM (Automatic Teller Machine or ATM machine) are
electronic devices that enable bank customers to make cash withdrawals
and check your account statements, deposit cash or checks, transfer
money between different accounts banks, using smart card or even buy
time for your phone at any time of day, 365 days a year, without having
to go to the bank.</i><br />
<br />
<b>History of ATM?<i> </i></b><br />
<b> </b> <br />
<div class="MsoNormal" style="text-align: justify;">
The first ATM in the world was produced by the firm <a href="http://www.ncr.com/about_ncr/index.jsp">NCR</a> and installed in London on June 27, 1967, by <a href="http://www.barclays.com/">Barclays Bank</a> . The invention is credited to John <a href="http://www.univision.com/content/content.jhtml%3Fcid%3D1217981">Shepherd Barron</a> , but no record that <a href="http://inza.wordpress.com/2007/07/08/el-primer-cajero-automatico/">George Simchi</a> handled the patent in New Yok from the 1930's. At first the process was taking too long and did not require a special key, which lent itself to fraud, so the current ATM customers to authenticate using a numerical code called a PIN. </div>
<div class="MsoNormal" style="text-align: justify;">
<b> </b></div>
<div class="MsoNormal" style="text-align: justify;">
<b>How it works?</b></div>
<div class="MsoNormal" style="text-align: justify;">
<b> </b> </div>
<div class="MsoNormal" style="text-align: justify;">
A card reader captures the credit or debit card and read the customer
information contained in the magnetic stripe is on the back. The data is sent to a central computer.</div>

<div class="MsoNormal" style="text-align: justify;">
With the receipt slot has the option to print or not the receipt of the transaction. The screen shows each step of the process: ATM Some monitors use CRT, others screen LCD. Some do the talking. Repeat instructions when a key is pressed and also gives information concerning the bank. Screen buttons are those who say the bank transaction type is required.</div>

of the most serious problems that can raise of not having proper
security settings is to lose control of the administrative privileges at
the hands of a threat to walk swarming a network.</span> <span>
In this sense it is good to know what you're being attacked and how to
protect yourself, and change the physical address of your network card
can make a big difference in the consequences.</span> <span> Here's <strong>how to change the MAC address</strong> to an application called <strong>MAC address Changer Tecnitium</strong> makes the complex seem easy.</span></i><br />
<br />
<h2>
<span><strong>What is a MAC address?</strong></span> </h2>
<span>
This consists of a 48-bit identification value acts as a unique and
irreplaceable in your card to the global communications network or small
home networks.</span> <span>
The number is composed of two blocks of different origin, as the first
24 numbers are designated by the manufacturer and the remaining are set
by the IEEE, a technical association with the work of standardization.</span> <span>
At this raises the question of which being that the MAC address is
seared in the ROM on the network device and ensuring that no two
identical network cards on a physical <em>level, how is that you can change?</em>
Telling the operating system Reading makes a "different" from her,
because ultimately it is this who realizes the existence of our network
card.</span><br />

<span> <strong>Change MAC address</strong></span> </h2>
<span> The application will use for this is <strong>Tecnitium Changer MAC address,</strong> which is</span> <br /> <span> fully developed to provide data on the status of your connection and your network devices whose primary function is to <strong>change the MAC address</strong> in order to avoid being identified on a network and remain protected from attack or test the security of the same .</span> <span>
In the application we can start by selecting the network connection is
active on our board, who can see a lot of details such as the IP address being used, the DNS server and many more than that, of course, could also be accessed from the Network panel in Windows.</span> <span> The important thing comes when we place the buttons at the bottom of the program, because from the <em>Change</em> button <em>MAC</em> can <strong>change the MAC address</strong> manually or trying to create random, which is what we recommend if you're not very knowledgeable about the issue.</span><br />

<span style="font-size: small;"><span> The DNS only the time involved in establishing the connection between two computers (eg when entering a site).</span> <span>
When the browser takes a long time to find a website (in IE it says
"Searching site: eldominio.com" in the status bar) is usually either
because our primary DNS is down or for some other reason (saturation of
users, etc.. ) has a very high response time.</span> <span> The DNS does not influence while transmitting information, such as when you download a file from a web.</span> <span> Therefore, a good DNS to improve browsing speed, but not the transfer.</span></span> <br />

<span style="font-size: small;"><span> In the configuration of TCP / IP can be specified in a list, which we want to use DNS.</span> <span> To resolve a domain name, our system sends the DNS query to the first listed.</span> <span>
If you are not operating, is declining and consulting the rest of DNS
in the order in which they appear, until it finds one that responds.</span></span><br />
<span style="font-size: small;"><span> </span></span> <br />
<span style="font-size: small;"><span>
Usually occur many times the ADSL connection is operational and yet if
we try to access a correct URL gets us "Could not find server or DNS
error."</span> <span> This is because at that time all DNS listed are down.</span> <span> To fix this just change the DNS for other than work.</span></span><br />
<span style="font-size: small;"><span> </span></span> <br />
<span style="font-size: small;"><span>
In principle it is advisable to use DNS to our operator as the
consultations have to go through fewer nodes and often give a better
response time.</span> <span> Only in the event that our operators are busy is convenient to use other external.</span> <span> Another solution is to use public DNS.</span> <span> Often the DNS operators have more than those who give their users and are often less crowded.</span></span> <br />

</div>
<div class="summary_title" style="text-align: justify;">
<b>1.</b><b> What is WiMax?</b></div>
<div class="summary_title" style="text-align: justify;">
<b> </b> </div>
<div class="summary_text" style="text-align: justify;">
WiMax - a high-speed wireless Internet.
Wherever you are - in a hotel, cafes, railway station or in a traffic
jam on the road, you can open your laptop and work on the Internet.
WiMax stands for: Worldwide Interoperability for Microwave Access is
translated as "International cooperation for Microwave Access." In the WiMax Forum includes companies such as Intel, Samsung, Nokia, LG, Motorola.<br />
<b> </b> </div>
<div class="summary_title" style="text-align: justify;">
<b> 2. How does WiMax?</b></div>
<div class="summary_title" style="text-align: justify;">
<b> </b> </div>
<div class="summary_text" style="text-align: justify;">
WiMax can transmit data over the air (like a mobile) in an urban
environment, not looking at buildings, trees or weather conditions.
WiMax transmitters installed providers in various parts of the city and
allow you to connect to the Internet within the entire coverage area
using a computer or mobile phone that supports WiMax. In addition to accessing the Internet using WiMax for high-quality voice and video communications. </div>
<div class="summary_title" style="text-align: justify;">
<b> </b></div>
<div class="summary_title" style="text-align: justify;">
<b>3. What are the specifications for WiMax?</b> </div>
<div class="summary_text" style="text-align: justify;">
<blockquote>
* Range: up to 50 km.<br />
* Maximum data transfer rate: up to 70 Mbps per sector in a single base station. A typical base station has up to six sectors.<br />
* Frequency: 2.11 GHz.<br />
* Spectral Efficiency: Up to 5 bps / Hz.<br />
* Coverage: enhanced work outside the line of sight significantly improve the quality of the coverage area serviced.</blockquote>
</div>
<div class="summary_title" style="text-align: justify;">
<b>4.</b><b> How safe is WiMax?</b></div>
<div class="summary_title" style="text-align: justify;">
<b> </b> </div>
<div class="summary_text" style="text-align: justify;">
First of all, for your health.
You do not say, but the frequencies that are running WiMax has long
been used by the military, so with the emergence of WiMax will be worse
than none. WiMax is not more dangerous to health than conventional mobile communication.</div>
<div class="summary_text" style="text-align: justify;">
And of course, wondering whether the safe transmission of data on WiMax for business? In WiMAX provides a triple data encryption algorithm, DES 3. Authentication is supported as part of the sublevel X.509 digital certificates (PK1). WiMAX devices have unique certificates, one for the type of devices, one for the manufacturer. Thus, it will be achieved an efficient and reliable protection of data streams. Therefore, based on WiMax, even created a virtual private network (VPN). They allow you to create secure tunnels for communication with remote users as well as within the company.<br />
</div>
<div class="summary_title" style="text-align: justify;">
<b>5.</b><b> What's better, EDGE or WiMax?</b></div>
<div class="summary_title" style="text-align: justify;">
<b> </b> </div>
<div class="summary_text" style="text-align: justify;">
EDGE - a suspension over mobile networks GSM / GPRS. Maximum speed EDGE - 474 kbps (slower than WiMax). The theoretical advantage of EDGE is more coverage.
However, support for EDGE in a GSM network requires certain
modifications and improvements of equipment that operators have been
slow to implement. Therefore, in practice, EDGE coverage is available only in relatively large cities. </div>
<div class="summary_title" style="text-align: justify;">
</div>
<div class="summary_title" style="text-align: justify;">
<b>6. What's better, Wi-Fi or WiMax?</b></div>
<div class="summary_title" style="text-align: justify;">
<b> </b> </div>
<div class="summary_text" style="text-align: justify;">
In most cases, these technologies are more friends, not competitors, because they are often used together.
Wi-Fi - is also a wireless technology that has approximately the same
rate as WiMax, but for much shorter distances of transmission. Wi-Fi is designed primarily to build local networks in environments with relatively small radius of action. The distance from the hotspot (the transmitter) Wi-Fi to your computer no more than tens of meters. But Wi-Fi now supported by almost every notebook and mobile phone. </div>
<br />
<div class="summary_text" style="text-align: justify;">
Therefore, Wi-Fi is often used to connect computers to the
WiMax-network, and WiFi-Internet providers are trying to make friends
and cooperate with providers of WiMax to provide a "last inch" of access
for customers.</div>
<div class="summary_text" style="text-align: justify;">
</div>
<div class="summary_title" style="text-align: justify;">
<b>7.</b><b> What's better, WiMax or 3G?</b></div>
<div class="summary_title" style="text-align: justify;">
<b> </b> </div>
<div class="summary_text" style="text-align: justify;">
3G - is the common name of technology 3-generation mobile technologies
that are designed to replace the mobile networks of GSM and CDMA. The most common technologies are 3G CDMA2000 1x EV-DO and UMTS / HSDPA. These technologies are competitors WiMax in mobile internet (ie internet access for those who travel frequently). They are slower than WiMax (maximum speed - up to 3.6 Mbps), but possess the same range.
In addition, the existing mobile operators is more convenient to
introduce 3G technology is compatible with existing networks, so
coverage of 3G networks are now more than WiMax.</div>
<div class="summary_text" style="text-align: justify;">
However, for new providers WiMax equipment is cheaper than 3G, so most likely they will develop a network of WiMax. In addition, with Intel, WiMax support will soon be implemented in most mobile devices - laptops and communicators.<br />
</div>
<div class="summary_title" style="text-align: justify;">
<b>8.</b><b> What's better, leased line, ADSL or WiMax?</b></div>
<div class="summary_title" style="text-align: justify;">
</div>
<div class="summary_text" style="text-align: justify;">
There is no doubt that today the majority of Internet users connected through the already laid cable or telephone lines (ADSL). And the connection speed they are quite satisfied. And even (perhaps) there is no need to go to the Internet from different places. But Internet access for businesses in our time must be truly reliable. No konnekta - business stops. A wired Internet service providers often use the monopoly position and not quickly eliminate the problems with the Internet.
Therefore, many companies and users use WiMax as an additional channel
of access, ensuring business continuity and independence from external
factors.</div>
<div class="summary_text" style="text-align: justify;">
In addition, the deployment of WiMax networks in undeveloped areas are
still - more cost-effective than laying cable, so in these cases, access
to WiMax will be even cheaper.<br />
</div>
<div class="summary_title" style="text-align: justify;">
<b>9.</b><b> How to connect to WiMax?</b></div>
<div class="summary_title" style="text-align: justify;">
<b> </b> </div>
<div class="summary_text" style="text-align: justify;">
Firstly, it is necessary to determine the WiMax service provider in your city and select one of its tariffs. Use the ratings of providers on our site.</div>
<div class="summary_text" style="text-align: justify;">
Typically, for connecting to sign a contract, get a sim-card and
purchase the necessary equipment (static modem adapter to your laptop or
phone). Sometimes ISPs provide their own equipment to rent and you do not have to buy it.<br />
</div>
<div class="summary_title" style="text-align: justify;">
<b>10.</b><b> What are the prospects for WiMax?</b></div>
<div class="summary_title" style="text-align: justify;">
<b> </b> </div>
<div class="summary_text" style="text-align: justify;">
Despite the fact that the Internet is in many cases to resolve issues
without leaving the office (for example, using the Web-conference), the
mobility of Internet users is growing every year. This happens because, thanks to the same Internet business becomes more global. Employees, partners and customers often live in different cities, different countries. But without a personal meeting, in some cases not enough.</div>
<div class="summary_text" style="text-align: justify;">
In addition, web-based applications that raise efficiency by an order of business is becoming more popular. Therefore, the demand on the global wireless Internet access will soon become the same as a traditional mobile phone. </div>Unknownnoreply@blogger.com0
