Computer Networks And Internet Protocol Television Essay The advent of computer has changed the way the world moves. Distance factor is no longer a problem. The physical might appear a big place with things at far off places but the world in virtual form doesn’t believe in distance. Everything can be achieved within minutes if not seconds. The whole technology behind this mega change is based on computer and is termed as Information Technology. This technology has led to the creation of a cyber world or electronically generated world with the help of computers connected to each other through suitable wires. Now words like cybercafe, cyber chat, cyberspace, cyber shopping, etc. have started making rounds. People can send electronic mails to far off places within seconds. Details and information are getting transferred within few seconds. People in Shanghai and New York are just seconds away. Transferring data in electronic form is actually the fastest way to transfer things. It’s not only the message transfer that has been revolutionized but also the business world. There are virtual shopping malls with website offering you a range of products ranging from computer peripherals to groceries. Companies are now providing details of their product through their website and are accepting customers’ requests of information and now even orders for products are being accepted. Everything is available. Money transfer can easily be done through wire transfer techniques. People do not wait. This world is not ruled by armed soldiers or any nuclear weapon. It’s the information which rules. The physical world just has to react on the outcome. Its role is just for receiving and sending. This high performing virtual world has made significant change in the performance of the actual world (Tanenbaum, 2003). Things in real world are now easier to comprehend. Outsourcing has helped in accessing low cost labor in far off Asian nations like India and China. Multinational companies like Microsoft, IBM, GM. , GE etc. have offices in almost in each part of the world with performance of each of these units can be monitored from any of its offices. Their offices have been networked though LANs i. e. , Local Area Network and WANs i. e. , Wide Area Network. They have virtually made themselves available to their customers any time anywhere and just a click away (Tanenbaum, 2003). 2. Computer System Network of computers A computer system and network of computers are actually two different but interrelated things. A computer system is just a normal computer including peripherals and software necessary for the functioning of the device (Webopedia). But if we talk of Computer Network, it can be defined in a very simple way as a network of computers (Princeton). But giving full importance to all factors getting into act when we talk about network, the definition which actually makes complete sense is none other than the two or more computers connected together to share hardware, software and data and has been implemented according to some topology (Tanenbaum, 2003). The network can have all peripherals located within an office or building. This arrangement is often termed as Local Area Network or LAN (Tech, 2006). If the same is achieved in a wide area i. e. , computers connected to the network are located at places as diverse as countries in different continents, we can call the same as Wide Area Network or WAN (Cisco, 2006). Calling all computers and other intelligent parts of it as nodes, the term network topology can be defined as patterns of links connecting a pair of nodes of a network. 3. Internet Protocol IPTV Technology related television services which include uplink and transmission has seen some of very revolutionary inventions of modern science. The television delivery system has now moved from terrestrial transmission through analog signals to encrypted digital signals through internet as well as IPTV (Anderson, 2006). The entertainment world through television is now very much eager to move from TV being delivered through cable to Internet Protocol Television with content being viewed through technologies used for computer networks (Lu, 2006). The last decade of the 20th century witnessed the massive growth in Internet Protocol based services. Now with the fast development of hardware and software technologies, this internet world has now developed to accommodate services like VoIP and many other telecom products (Wikipedia, 2007). It is a system which delivers digital television services to registered subscribers in a managed network with address based technology. The unique IP address of a subscriber provides him a virtual address over a network and creates a connection between the service provider and the television (Wikipedia, 2007). 4. Television through IPTV: a new experience IPTV is going to give the most electrifying experience to its subscribers. It’s not just seamless TV viewing but also more interactive and personalized. Things like participation in a game show or any discussion board will only require the use of the remote while sitting on the couch. Now the user will not feel being bombarded with a long list of channels rather get a very creative option to receive them with a much richer experience (International Engineering Consortium, 2007). The two-way signal broadcasting system through the network over which IPTV depends, allows the viewers to make selection that too on demand with time shift option. The additional services which can also be incorporated with IPTV are the Web Browsing i. e. surfing the internet, gaming with a game console with the current system and finally the communication applications which can enable email, MMS, Chat, etc (Telecom Italia, 2006). Figure 1 (IPTV delivery Infrastructure) The Set-Top Box which has made this IPTV happen which at one end is connected to the TV set while the other end to an ADSL connection can easily be made to supply Broadcast TV services (BTV) as well as Video On Demand (VOD) services. This BTV facilitates the simultaneous reception by the users of a traditional TV channel. And using multicasting protocols IPTV can make available services which are similar to experiences of a traditional TV like Free-to-air or Pay TV or a Pay-Per-view service (Luarel Networks). The same IPTV can be used by service providers to provide the VOD service which is made available on request. The VOD service requires implementation through IP unicast protocols (Ericsson, 2006). The enhanced IPTV can also make Personal Video Recorder (PVR) services available. The local PVR makes way for video-recording on the STB hard-disk with another set of functions for live, pause and replay. Similarly the Network-based PVR stores the data on the operator’s server which is generally used for VOD (International Engineering Consortium, 2007). On technological point, the IPTV makes way for better utilization of available infrastructure like the bandwidth. Traditional transmission technology actually sends more than hundred channels simultaneously while the IPTV requires just one channel to be sent to the subscriber at a time. Every time the user selects a channel or a program, a new streaming takes place with data related to the newly selected channel (Anderson, 2006). 5. IPTV: More Advantages, More services More Business The IPTV will lead to a very new level of interactivity among Internet and data mainly as voice and video. A cable based TV network beams data in form of video mostly in MPEG format through an explicit bandwidth portion while the internet which enables high speed data transfer works on an IP based network and the data transfer is based on packets rather than streams. Both the technologies are technically very different. This IPTV is an amalgam of both the successful technologies. Being a data-centric application, the packets over this network can deliver both video as well as data (International Engineering Consortium, 2007). Figure 2: Telecommunications IPTV system solution The traditional cable network is often overloaded with more than 100 channels being transmitted simultaneously. So there is a limitation of maximum number of channels that can be made available to the subscriber. IPTV has a very clear advantage (Times News Network, 2006). Theoretically this technology can make almost infinite number of channels at the customer’s disposal. The transmission line actually transmitted a single channel which has been demanded by the customer. So the infrastructure usage per customer is negligible while opening a new era of almost every channel on the planet being made available to the user. The IP technology being a packet based product requires an acknowledgement to be sent to the source for every packet. This ensures that every packet sent by the source should remain intact and any loss of data will require resending of the same packet. This feature ensures very high quality of the product which the subscriber will receive (Anderson, 2006). The advantages associated to IPTV is not just conventional entertainment and advertisement based business but the technology can have its usage in developing new products which can make way to many other forms of businesses. The web based training is one of the many other possibilities. The IPTV network can be used to run different courses by making the videos of the classes available to the registered students (International Engineering Consortium, 2007). IPTV is the next big thing after telecom and internet. The business possibilities associated with this technology is almost as broad as the human thought. Almost all telecom companies are putting big money in exploration and marketing of this product (Blau, 2005). The business network and the corporate LAN’s may be greatest beneficiary with the delivery of videos and television content. The customized content delivery and the extremely secure network will reduce the theft cases to negligible. Customization facility will help the advertisers to understand the behavior of consumers and then will go for personalized ads that will translate into significant business returns (Iyer, 2005). 6. Conclusion The IPTV is going to be the next big thing in communication and media industry. With money pouring inform all big telecom companies IPTV is going to be a very serious business with entertainment becoming more and more customizable. The subscriber will experience a very different medium of entertainment with highest level of interactivity and almost innumerable possible services that too very much on his own wishes. 7.

Organising tour for Signed Act :: essays research papers

In order to organise a tour for a signed act, it takes the efforts of management, the record company, agent and promoter. Although each have their individual responsibilities and ways of working it is required of them to work together as a team in order to make a tour possible, or even for just one gig. They each contribute an essential part of the process and organisational strategies and without co-operation of each unit organising a tour would be practically impossible. Disagreements could cause much of an inconvenience and the music industry being so large with so many people disagreements are not uncommon as everyone has their own opinion. Compromise is perhaps the only key, therefore working with open minded people makes it much easier. Often the job descriptions of each unit intersect and are hard to define, which can sometimes be helpful as different people can do the same job from different angles, however it can also get confusing and cause problems often being the result of communicational breakdowns. In this essay we shall study what each unit does and how they work together looking at the advantages and disadvantages of certain aspects and perhaps discuss ways in which the system could be improved. Management The management company works with the artist more so than anyone else. They play a dominant role in their interaction with people in the music industry (agents, promoters, record labels). Their own interaction with the artist is direct and they often have a freindly relationship with the artist. I spoke to an unsigned rock band with a management contract to find out exactly what they do for them. Their management company were an established music company who create music for adverts and therefore have knowledge and contacts within the industry. They provide the band with financial backing for equipment, recording sessions and any other finances to support the band. They also act as an agent for the band and book gigs by contacting promoters and promoters also often contact them. Their relationship with the band is very friendly and are on terms were they both work for each other. Their management push and motivate the band to work as hard as they can to improve their material and perhaps influence it to be what a record company might want to hear. They are usually responsible for any exposure the band receive, for example interviews, airtime, music journals etc.

The sculpture Bodhisattva

The sculpture Bodhisattva had the strongest impact upon me for various reasons. This piece, found in the Silk Road Chicago collection at the Art Institute of Chicago, is a cross-cultural work with obvious Eastern and Western influences. This sculpture is a beautiful 2nd to 3rd century A. D. piece that depicts a man standing in obvious deep meditation. This model was created in the region of Gandhara, which is modern-day Pakistan and Afghanistan. This early representation of a Buddha-like figure is a unique and powerful image. The title, Bodhisattva, can be directly translated from Sanskrit as meaning a â€Å"spiritual essence or being.†This figure is an interpretation of a sacred being that has delayed its own nirvana in order to help others reach the spiritual plane. The adornments that this figure wears are representative of its delay to the spiritual realm. Wearing material and worldly items means that it has not transcended yet. This type of commitment is impressive and th e figure is blessed with the incredible ability to be in a state between both worlds. The figure in the sculpture has an awe-like power over the viewer. It makes you feel as if you are looking at an object that attains holy attributes.Although, the sculpture has divine qualities, it also makes the viewer feel able to relate to it. It is humanized in a way that differs from other Buddha representations. This makes the impact of the work even stronger. An inner strength is portrayed that varies from the traditional at rest Buddha that is found in most artwork. This figure has power, but it is not menacing. It is serene and this serenity is transferred to the viewer of the piece. It is easy to see how these types of figures transcended into what is now modern-day Buddhism. The bodhisattvas were ancient spiritual beings that were worshipped.The collective group of these became the Buddha figure that is widely known today. The detail of this sculpture is incredible. Despite its age, the particulars of the piece have remained blissfully intact. The hands are missing, but it is possible to guess at how they were placed in the sculpture. The right hand was most likely raised and assuming a gesture of reassurance. An object found in the left hand would determine the type of bodhisattva. There is realism in the depiction that makes the viewer feel that they are gazing upon an actual interpretation. Unlike other bodhisattva pieces, this work feels more based on a real person.Despite the Eastern subject matter, there is little doubt that there is Western influence apparent in this piece. â€Å"The art of this region experienced a type of merger with Greek influences after Alexander the Great conquered the region in the 4th century B. C. † (Rowland, 1960, 8). An example of this found in the Bodhisattva is clear in the figure’s intricate robes. These types of folds are traditionally found in Greek and Roman artistic depictions. The drapery reminds the viewer o f the togas worn by the figures in the sculptures of Roman imperials. The chest of the figure is also reminiscent of the merger of these two cultures.It is a more realistic portrayal with the muscular indentations found upon the figure’s chest. Eastern portrayals had less defined bodies in their works. The Indian traditions of the sculpture are displayed in the figure’s mustache and the dhori that he wears. The dual influences of this work made the most significant impact upon me. It is rare to see a piece that has such obvious Eastern and Western elements found in the manifestation. This cross-cultural work is a harmonious interpretation of a strong spiritual figure. Additionally, it has a strong religious impact.It is a documentation of how Buddhism made it way from India into China. When looking at the sculpture, it is unavoidable that you are not moved at how this is exposing a historical occurrence. The stone material of the piece lends power to the idea that this is a strong figure that is tied to the material world, but has the ability to guide people to their own nirvana. The lasting material makes the viewer feel as though they are looking at a spiritual piece that has transcended through the ages. Buddha is an important figure in artwork and it is essential to know how this form came into being.

Analysis of Herman Melville´s Moby Dick Essay - 821 Words

Herman Melville, in his renowned novel Moby-Dick, presents the tale of the determined and insanely stubborn Captain Ahab as he leads his crew, the men of the Pequod, in revenge against the white whale. A crew mixed in age and origin, and a young, logical narrator named Ishmael sail with Ahab. Cut off from the rest of society, Ahab attempts to make justice for his personal loss of a leg to Moby Dick on a previous voyage, and fights against the injustice he perceived in the overwhelming forces that surround him. Melville uses a series of gams, social interactions or simple exchanges of information between whaling ships at sea, in order to more clearly present man’s situation as he faces an existence whose meaning he cannot fully grasp.†¦show more content†¦Gabriel warns Ahab that if he keeps pursuing the white whale his end will come. Ahab refuses to listen because he is selfish and is too determined to seek his revenge that he will risk his life and his crews life so h e can kill the creature of the deep. Similar to Ahab, the Samuel Enderbys’ captain has donated a limb to Moby-Dick, but unlike the Pequod’s leader, the Englishman wants to keep away from the White Whale, arguing, â€Å"ain’t one limb enough? What should I do without this other arm? †¦ He’s best left alone† (368). The one-armed captain, head of a ship named for a wealthy British merchants, describes his experience to the one-legged monomaniac, who is overly excited, but the Englishman does not approach the experience as a spiritual battle like Ahab. Interrupting the captain, Ahab exclaims his highlights of his effect on the whale, claiming credit for the harpoons and scars decorating that wild beast. The Samuel Enderby’s captain continues â€Å"good-humoredly† (365). The Englishman did not know that he had lost his arm to the Moby-Dick for some time after the attack, but when he found out the identity of his opponent, he forfe ited two chances to repeat his attempt at capturing oil from the White Whale. To the Englishman’s sage like attitude, Moby-Dick was nothing more than a remarkably profitable catch, while toShow MoreRelatedHerman Melville s Moby Dick 1471 Words   |  6 PagesHerman Melville has become a well-known classic novelist in today’s society, most popularly known for his novel Moby Dick.
