Every computer has a port to connect a communication line or cable from a peripheral device. Computers have limited number of ports, so multiplexers are used. They combine signals from multiple terminals and put them all on a single communications line. This increases the efficiency of communication and is cost-effective. The communication line is divided into different sections and the data from each terminal is coded and sent and then received, decoded and directed to the correct section from where it came from. There are four commonly used types of multiplexing, the first is (FDM) frequency division multiplexing. FDM divides the bandwidth of the communication line so that each terminal can transmit data. The individual terminals are separated from guardbands to ensure the signals do not interfere with each other. Multiplexers often have external modems or internal modems built in to convert the data to analog before transmission takes place. The local cable television companies use FDM to send multiple stations over the same line at once.
Another method for combining data on a transmission line is time division multiplexing, instead of dividing frequencies to transmit signals, TDM divides the transmission line into time segments. Each terminal is assigned a fixed time slot on a rotation. When the terminals time slot appears it receives the full transmissions capacity for that line. TDM is like packet switching except the time slots are pre-allocated. Instead of using gaurdbands to separate signals TDM uses guard times. If a terminal has no data to transmit at its specific time, the line remains idle. In TDM terminals rarely transmit continuous data which means some sections of the line are almost always idle. In STDM (statistical time division multiplexing) the same concepts apply except if the terminal doesn’t have any information to share it’s time slot will not be created and will move on to the next available terminal, producing less down time. STDM is driven by data, they also perform more operations than TDM. They provide buffers, and can compress data and report statistics, support digital data, and modem capabilities.
The first wavelength division multiplexing system combined two signals and was created 1985, modern systems can handle 160 signals. Telecommunications companies like this technique because they can easily upgrade there lines without having to overhaul the network backbone. It uses same idea of FDM but with fiber-optic cables. The line assigns each signal a particular wavelength.
Three years later, enter Banksy, a world famous street artist from England. Banksy has become famous ironically through his use of anonymity as an artist. Banksy will choose a city somewhere in the world and embark usually on a month long anonymous crusade where he “tags” different buildings with culturally and politically motivated works of “street art”. When Banksy descended on New Orleans, he painted 14 works of street art in total, but the painting that stood out as the most glaringly political was the painting called “Looters”. (Banksy story)
In the film ''exit through the gift shop” Banksy made an documentary film, the film examine street art, graffiti and the surrounding subculture as well as the lives of the artists. Banksy is a British graffiti artist and painter. While Banksy is out and exploring the world, A man name Therri Guetta, a friend of Banksy and also a artist. Therri has a obsession with filming, capturing everything in camera, so Therri insist to record everything on Banksy art quest. Banksy in ''Exit throught the gift shop” wants to stay anonymous in his art work and he may be one of the most mysterious street's artists. Street art started with artists expressing themselves through their creativity and designs, on images posted in public, but turned to a moneymaking operation for Banksy in ''Exit through the gift shop”. Banksy create his art work in the dark, on a wall, or signs, with minimal supplies and the rush it gives him is all based on the fact that it is all considered illegal. Although, in the past, Michelangelo was born in Tuscany in Italy on the 6th of March in 1475. He was an Italian painter, a sculptor, an architect. His strongest skill was specialized in painting and sculpting. Two of Michelangelo works, the “David” and “Pietà” . Born in Tuscany, Michelangelo w...
Banksy instigated his graffiti art routine by admiring the workings of Blek Le Rat and often reusing his past ideas. He has been a part of the graffiti sight ever since the early 90s. Originally, he was with a graffiti crew in Bristol by the name of DryBreadZ crew or DBZ. A while later, he created a
Like a lot inventions in the past two centuries, modern fibre optic cable was created for military uses. The manager for Copper Cable and Wire at the US Army Signal Corps was getting more displeased with the amount of signal loss that was due to copper cable.
It all began in the 1990’s in Bristol England, when Banksy began as a freehand graffiti artist. With the help of two other graffiti writers, Kato and Tes, they formed Bristols DryBreadZ Crew (DBZ). Their inspiration stemmed from the local hip hop and breakdancing community and eventually they gained notoriety and size. By the late 1990’s Bristol became too small for Banksy as he was starting to become a street art sensation. Concerned about his anonymity, since graffiti is highly illegal, he fled to London ...
It is clear to see how improving communication climates, interpersonal communication in close relationships, communication and relational dynamics intertwine with each other. Which are just the basics for understanding how to have good communication skills in relationships. When being in a part of a family, friendship, work mate, or romantic relationship it is crucial to know where your relationship stands between one another. Each relationship is important, that is more vulnerable than others due to their uniqueness, availability, and loyalty. Whether it is a personal or social relationship, they all began going through the coming together stages of relational development. This communication allows us to test our potential and current relational relations by initiating, experimenting, intensifying, integrating, and bonding. Adam and Emma incorporate all of these stages from the beginning of the movie when they bond by talking about his parents getting divorced at camp one night then Adam randomly asked her
The history of the underground movement, known by many names but traditionally known by``graffiti,`` began in Philadelphia, Pennsylvania during the mid to late 60`s. Graffiti is grounded in bombing, a practice of painting several spots in a single area. The style of urban graffiti that we know today is the kind with spraycans, and came from New York City in...
Simultaneous communication, also known as Sim-com is a form of communication process that utilizes both signs and sound. Quite often Sim-com has been referred to as a sign supported speech; these signs are usually in English in order to ensure that there is fluency in the language. In this, it is noted that some other non-verbal cues like the use of finger spelling and visual aids which rhyme to the spoken language can be used. Simultaneous communication has always been known to be a form of communication that is intended to help people who have hearing problems (deaf) understand what is being said. In this, it is realized that over the years, Sim-com has been able to utilize other systems of communication like seeing essential English. Sim-com has proven its advantageous use in both the deaf and hearing people because it presents both the spoken language and also the non-verbal. Simultaneous language is not only used by the deaf, but also used when communicating with students at the preschool level. This is important because these children tend not to understand verbal communication fully (Beginnings, 2014).
All forms of commerce will benefit from fibre optic connectivity as it will lower the cost of communication, which is a vital part of any business. New opportunity for the growth of the data market will emerge as cheaper bandwidth should translate to more users.
Although other artists know who he is, Banksy doesn’t have a public face that he shows at galleries and in his documentaries. In Will Ellsworth-Jones article “The Story Behind Banksy: on his way to becoming an international icon, the subversive and secretive street artist turned the art world upside-down” he talks about one of Banksy’s earlier galleries. Ellsworth-Jones says “The show was a high-profile demonstration of the phenomenon that has come to be known as the ‘Banksy effect’—the artist’s astounding success in bringing urban, outsider art into the cultural, and increasingly profitable, mainstream” (2). Banksy’s “effect” is altering urban culture and bringing it to art galleries to be displayed and sold. In the grand scheme of things, he is commodifying graffiti and urban culture, making it more consumable and then proceeding selling and profit off of it. In A&E’s biography page for Banksy they state that Banksy’s work is unique due to the fact that it “often engages political themes, satirically critiquing war, capitalism, hypocrisy and greed.” The uniqueness of his work is a common reason different news outlets give for Banksy’s success. Contrary to popular belief, Banksy’s content isn’t groundbreaking. Artists of all mediums, including graffiti, before and during his time have touched upon all of the same themes as
A large portion of his work can be found in busy cities, such as London and New York. His classic mediums consist of concrete city walls, stencils, and spray paint. There aren’t many vetted sources that tell the story of who he is, where he is from, or any substantial information about him. One is only left to assume his passions, which we derive from his art. His piece, “Girl With Balloon,” was meant to be viewed by those who have lost or are losing hope. The city wall that holds this piece of art is not well kept, spray painted in what is likely an area that is impoverished and full of dying hopes and dreams. Banksy’s purpose is found in the eye-catching heart-shaped red balloon that is followed by the portrayed innocence of a young girl reaching towards love and hope, and of course the statement behind it, says it all on it’s own; no matter what the circumstances, don’t give up – don’t lose hope. This image is meant to bring about desire for a new way of living, and certainly the aspect of finding hope. A child will most likely be drawn to the red balloon and portrait of themselves, whereas the adult will be drawn to the saying behind the portrait. Parents will be more inclined to feed their children positivity, potentially go after their own dreams and find their own meaning and remember the words that go along with the picture, whereas children are likely to remember the picture and what it
Digital Subscriber Line new technology that takes advantage of standard copper telephone line to provide secure, reliable, high-speed Internet access. DSL refers to the family of digital subscriber line technologies, such as ADSL, HDSL, and RADSL. Connection speed for DSL ranges from 1.44 Mbps to 512 Kbps downstream and around 128 Kbps upstream. Unlike traditional connections DSL such as analog modems and IDSN, DSL deliver continuous “always on” access. That means multimedia-rich websites, e-mail, and other online applications are available anytime. DSL makes it possible for you to remain online even while you’re talking on the telephone-without jeopardizing the quality of either connection. DSL is available in a spectrum of speeds. Some are best home use, while others are designed to accommodate rigorous business demands. Whether for business or the home, DSL, offers unsurpassed price/performance value compared to other online options. There are the five facts that one should know about DSL. It is remarkably fast. With DSL service, you can benefit from Internet speeds that are up to 12 minutes faster than a typical ISDN connection and 50 times faster than traditional 28.8 Kbps modems. This means that in the 12 seconds it takes to read this information, you could have downloaded a 2 megabyte presentation file or web photograph. It would take 10 more minutes (600 more seconds!) to download the same with a traditional 28.8 Kbps. It’s highly reliable. One can depend on DSL because its proven technology takes full advantage of the existing telecommunications infrastructure. It’s inherently secure. DSL network provides a dedicated Internet connection via private telephone wires, you can bypass dial-up intruders or shared network hackers. Unlike traditional dial-upp modems or cable modems. DSL protects your valuable data with the most secure connection available. It’s surprising affordable. DSL is widely recognized as the most cost-effective connectivity solution for small buisness. DSL delivers industrial- strength like speed to multiple users at only 25% of typical TI costs. There is no better price option available. DSL is also an exceptional value for home users. At about $2 a day for services that meets the needs of most people. The connection is always on. It’s ready to run every minute of the day. There’s no more logging on and off. No more busy signals or disconnects. This gives you the freedom to focus on what you want to accomplish on line rather than focusing on trying to get connected.
What many do not understand is that street art and graffiti are completely different things. For ages now, strain has been lingering and bubbling under the surface between the graffiti writers and street artists. The majority of passers-by merge and confuse one with the other, unquestionably, there are notable distinctions between them. Most people that carry out graffiti are not coached or shown how to and are constructed mainly on words, usually it will be names or foul language scribbled on the walls. It arisen for teenagers as a way to reveal themselves, it is typically observed as
Art can have many different definitions to people all over the world. But the two consistent things that all art has to have are, a purpose and be original. Anyone can make art, weather it is a book, drawing or theater, but for it to be considered art it has to have those two traits. An example, Banksy’s drawing in Tribeca of the Twin Towers is an example of art. He clearly sends a message with that drawing, that the city of New York still remembered the traumatic event but is looking towards the future with hope. Also, this stencil drawing is an original, which is another reason why it is considered art. Another street artist similar to Banksy is Mr. Brainwash. He also has a purpose behind is art, which is to get the audience to react to his work rather then expressing his political ideas like Banksy.
