Family Essay

It will begin from basic talks and later become a major discussion among our relatives. It sounds amusing yet that is the means by which we have our family social affairs. Truth be told, examining current issues make our spirits alert and alive however in the event that there is none, our social occasion will get exhausting and appears to be fragmented.

Despite the fact that I have this sort of disposition that like to discuss even on straightforward issues, I do in any case have my companions that stay with. There are times that we contend on gibberish things that occasionally lead us to a â€Å"fight†.

The contention began when she admitted to me that she and her sweetheart had reveled into pre-marriage sex a few times. My underlying response was stunned. I couldn't talk for a second in view of her admission to me. I was stunned with her admission not on the grounds that the thought itself is unfamiliar to me but since I was not expecting them do it. I confided in her sweetheart especially that he will do nothing incorrectly to my companion since I expect him as an individual who needs my companion to be protected even we are in this risky occasions where our ethics are as of now breaking down. I am not against on engaging in sexual relations since it is an endowment of God to be delighted in by people explicitly for the wedded individuals however doing it outside marriage is a major â€Å"no, no† to me.

In the event that you don’t experience it, individuals will view you as â€Å"loser† and quitter however on the off chance that you do, you will pick up their thankfulness and endorsement. Could it be any more obvious? This is the means by which our reality being defiled of common delights. Also, I don’t accept that if everyone is doing it, it is now right. We need to maintain our ethics as individuals and not letting the things of this world impact and degenerate our great character. That is one of my feelings as an individual. Moreover, she kept on transferring to me the things they did in full subtleties and quiet came up in the environment. I just permitted her spill her guts on me. Following a couple of moments, I asked her for what good reason she sticks for that thought and allowed it to occur. Be that as it may, she just replied, â€Å"Why not? Everyone is doing it. What's more, we love each other without a doubt. I was irritated and nauseated with her answer however I attempted to keep down my temper and attempting to make a â€Å"good† conversation with her in regards to the issue. In this way, I kept asking her. â€Å"Do you believe that is the main way you can communicate your adoration to your sweetheart? † I inquired. At that point, replied back â€Å"what do you mean? We do this since we love one another. Don’t you comprehend! Also, don’t you ever set out to direct my life on what should I do. You are not my folks! † she shouted. Those words struck me a ton. I am simply talking about this issue to her since I love her as my dear companion and I need the best for her. I am trusting that, through our conversation, she can have the option to understand the potential things that may happen to her later on the off chance that she and her sweetheart will constantly enjoy on it. So I disclosed to her that despite the fact that everyone is doing it, it doesn’t imply that it is as of now right. My point was, despite the fact that everything is passable yet not all things are helpful. Everything is reasonable yet not all things are valuable. What appears to be on the whole correct to our eyes may lead us into obliteration. I revealed to her that she is simply wrecking her life. Her poise as a lady was lost. I am attempting her to comprehend my point that I would simply need her to protect her virginity until she will get hitched in light of the fact that that would be the main best blessing she can provide for her better half beside her valuable love. In any case, she decided not to comprehend my point since she was â€Å"extremely† in adoration with that person. I can comprehend her sentiments yet I can’t endure her activities. What she just believes is the current bliss and not searching for the potential outcomes later on. I disclosed to her that each activity she will do has its outcome. It may be correct or wrong. At that point, I asked once more. â€Å"What in the event that you get pregnant? Is it accurate to say that he will acknowledge the obligations and wed you? † She was quiet for a little while and thinking for an answer. â€Å"Well†¦My sweetheart loves me so much and I am almost certain that he will! † she answered and I can consider her to be to persuaded herself as she said those words to me. â€Å"Oh, well†¦ if that’s the case, I can’t drive you to tune in to my advices. I regard your sentiment and choice since that is your life. In any case, consistently recall that I am not encroaching your own life. I am simply stressed what may be the results of your activity and on the off chance that you are truly prepared to confront that outcome. † I reacted. Along these lines, that contention is shut and I am imagining that it will never be an issue again to the two of us. As time cruises by, she kept on sharing to me what she and her sweetheart were doing and it was about their sex adventures. I do hear her out even I don't care for what I am hearing. I am attempting my absolute best to get her and advise her that it isn't yet late to change. However, she will simply disclose to me that there is nothing amiss with her. Truth be told, she is glad to encounter it. At some point, she called me and inquired as to whether we can feast out. We went to our preferred café. At the point when I saw her, she looked anxious and worn down. I grinned at her and asked, â€Å"What isn't right? How are you and your beau? † She just grinned harshly to me. â€Å"Why? † I asked once more. â€Å"I am pregnant and I don't have the foggiest idea how to manage this child. † I just took a gander at her and said nothing for a second. â€Å"I will prematurely end this child! † She began to cry. â€Å"No! † I said. â€Å"Did your sweetheart find out about this? † What did he say? † As I posed those inquiries, tears continued falling on her eyes. â€Å"Tell me†¦ What did he say about the child? † I rehashed. â€Å"He needed me to prematurely end the child? He doesn’t need to wed me since we are as yet youthful and he has no activity yet. I advised all her the child and quit worrying about her beau. Anyway, she can fare thee well and give the necessities of her child in the event that she needs to. Be that as it may, she revealed to me straight all over that she will prematurely end the child. Because of her disarrays, premature birth came up into her psyche as an extreme solution for her ongoing issue. I revealed to her that she previously dedicated sin once, the wrongdoing of submitting pre-marriage sex, and now she ought not sin again by prematurely ending her own kid. It isn't right. It is ethically wrong. You are slaughtering a guiltless youngster, a kid that has no solidarity to safeguard and battle for himself. This time, I constantly contended with her not to prematurely end her child. I revealed to her that the blame will consistently frequent her for an amazing remainder. She may get away from the disgrace for having a child without a spouse yet she won't most likely get away from the blame that will always frequent her inner voice. She was difficult on the grounds that she revealed to me that she needs to prematurely end the child since she can't deal with the duties and the disgrace. I revealed to her that every one of those despises from others will simply pass and never be recalled again as the time will pass however the life of her child can't be pull back from death once it is prematurely ended.

Questions: 1.How the Australian government makes laws? 2.How the financial force is shared? Answers: Making of the Australian constitution Prior to the beginning of the twentieth century, the current conditions of Australia were independent provinces of the Empire of British individuals. Every one of the settlements was welcome to go to an organization after the provinces chose to meet up and the gatherings (which were known as the shows gatherings) were called to concoct a constitution which was intended for another country. The endorsement of the draft constitution was finished by a vote of individuals in the submissions which were held in each cluster(Moen, Gabriel, John, Richard, 2012). The recently shaped Australian Nation was given a foundation in first January 1901 and the last was finished after the death of the federation of Australian constitution act by the parliament of the United Kingdom(Moore William , 2013). The constitution that had been drawn up at the understanding framed piece of this Act and which gave a statement that the constitution of the province would be as per the following: Jobs of the Australian constitution Australia would be alliance of States having their own constitution, organization and rules.

Marketing and the Apple Watch Essay

Promoting happens inside an association when customers needs, needs and requests are met with the trading of an item (Kotler and Armstrong, 1991). The idea is association wide, and especially significant when new items are presented inside a market. Client esteem is a significant part of promoting, as it helps in investigating what the purchasers saw needs and needs are. Client worth can be characterized as the advantages picked up, and forfeits made so as to buy an item. The principle wellsprings of significant worth made by the association are useful/instrumental worth, experiential/epicurean worth, representative/expressive worth and cost/penance esteem. In this paper we will be looking towards the fore coming Apple Watch for instance. Advertising is a very wide idea. Accordingly when endeavoring to characterize the term, the assorted implications it has for a wide range of individuals and gatherings must be recognized. (Kotler, Shaw, FitzRoy, Chandler, 1983). The term at its center identifies with considerably more than simply the selling and promoting of items. The ideal point is for items or administrations to be uncovered in an animating way for both backhanded and direct clients of the association. The basic misguided judgment of the term â€Å"marketing† is that its center component is to just sell an item or administration. Be that as it may, showcasing as a business theory is embraced all through the entire association, and through all degrees of the executives (Keelson, 2012). It is a methodology where the customers’ needs and needs should be the essential worry all through all business choices. Kotler et al (1983) investigates the term further by contending that advertising is the way toward utilizing exercises and organizations that empower correspondence, liberation and the trading of contributions that offer some incentive for a wide cluster of clients, just as society on the loose. Promoting has some principal ideas connected to it †the above all else being human needs, identifying with individuals feeling denied by not having products or administrations (Kotler and Armstrong, 1991). Human needs are perplexing and come in wealth, and from these apparent needs human needs are set up. Human needs are to a great extent reliant on the necessities of people, as they are formed by singular societies and improvement (Kotler and Armstrong, 1991). Once anâ individual wants an item and has the ability to buy it, these needs are changed over to requests. Above all inside the procedure is the trade, saw as the basic guideline of advertising (Woodall, 2004). Identifying with acquisition, obtaining the ideal item from an individual while offering something consequently. An item is basically anything offered to the market so as to fulfill their apparent needs and needs (Kotler and Armstrong, 1991). For this situation the Apple Watch will be talked about. The item or administration will be aimed at a particular market, which involves all potential and real purchasers (Kotler et al, 1983). The Apple Watch is being focused at the overall population, however more explicitly a hyper center towards recently settled Apple clients and fans with an affinity for predominant products. These thoughts are significant parts of advertising as they give data to the association to figure out what merchandise and enterprises to offer. Promoting is tremendously imperative to any association, paying little heed to measure or kind of item and administration on offer. The point of experiencing showcasing is to convey a way of life to individuals, furnishing them with items for when and where they need them (Kotler et al, 1983). The idea of advertising is as a rule pushed by income; organizations need to add to their benefits by fulfilling client needs. Without appropriately executed showcasing capacities set up, where the clients needs, needs, and requests are not adjusted inside the exchange, at that point the association has minimal possibility of accomplishing an upper hand, just as picking up an incentive for themselves. (Keelson, 2012). Utilizing the case of the Apple watch, which has been underway for quite a while, Apple have been amassing their thoughts, while watching the aftereffects of other adversary organizations discharging comparative adaptations of the item. Apple have been cautiously focusing on the c lients needs and needs, and are at last prepared to discharge the final result to expectedly energetic shoppers. Client esteem basically is the apparent advantages finished up by the client, got from getting the item held facing the sacrificesâ being made to obtain the item (Weinstein, 2012). Associations making esteem, besides client esteem is logically being viewed as a new and modern wellspring of upper hand (Woodruff, 1997). Along these lines, the formation of client esteem is a staggeringly critical focal idea inside promoting (Patterson and Spreng, 1997). Anyway there isn't one single settled upon definition that might be utilized for client esteem, just as no unmistakable authoritative hypothesis or system used to stress client esteem (Weinstein, 2012). Receiving the manner by which associations can make worth, Smith and Colgate (2007), have built up an imaginative system where four sorts of significant worth made just by the association are recognized †these being practical/instrumental worth, experiential/indulgent worth, emblematic/expressive worth and cost/penance esteem. Utilitarian and instrumental worth alludes to the purchaser buying the item and having it complete the capacity it is intended to do (Smith and Colgate, 2007). All the more so worried about the product’s properties, execution and results. All together for the Apple watch to achieve this worth, the savvy needs to have all highlights including exact time, Wi-Fi, and client to-client availability in a way that is anything but difficult to work and comprehend, just as solid for the customer. This appraisal of significant worth may change between people. The experiential/libertine worth is progressively expelled from the item itself, and increasingly identified with the sensations we get from the item. All the more explicitly connected to the sentiments and feelings we get, just as reasonable encounters for the client (Weinstein, 2012). Tim Cook, the CEO of Apple has titled the Apple watch as the most close to home and personal item yet (Apple, 2015), with the watch making you of notices through a little vibration aware of your skin. Proceeding with tangible incentive inside the watch, Apple have worked with high style creators and beauticians to guarantee the item looks extraordinary, just as discharging a wide exhibit of styles appropriate for anybody. Moreover, the savvy being one of Apple’s most stylishly satisfying items to date, it is accepted that customers will buy because of joy of having it (CNET, 2015). This feeling of happiness and experience holds enthusiastic incentive for the purchaser. Emblematic and expressive worth is appropriately focused on the degree in which the client will give or partner mental significance to a particular item. In addition as far as self-character, and whether the item empowers the purchaser to communicate their characters, just as joining social importance (Smith and Colgate, 2007). There are an enormous assortment of Apple watches that might be bought with contrasting costs and styles. This gives the purchaser a lot of decision, and a capacity to communicate as far as configuration in hues, state of watch, and wristbands. Tending to self-esteem and self-character, previously mentioned the watch comes in numerous styles with various sticker prices, the 18 carrot gold apple watch could speak to an individual needing to represent glory, and status, and consequently cause the purchaser to feel great about themselves. Anyway close to home significance is staggeringly explicit to people, and for advertisers this can be exceptionally hard to ac complish. The expense and penance esteem identified with the things we provide up so as to acquire the item, including time, cash, individual ventures and the dangers in question (Slater and Narver, 1994). Apple has given a wide cluster of costs extending from AU $499 to $24,000 (CNET, 2015), implying that individuals can pick the dollar sum they pay. As this is Apple’s first endeavor at promoting an item intended to be worn, the real buy experience will inconceivably vary. Apple workers have been prepared to be substantially more client centered, posing inquiries and causing the purchaser to feel good (Apple, 2015). Anyway the item has an elevated level of individual venture, and dangers connected to the real acquisition of item. As the watch stays a piece of the advanced computerized electronic world, there is consistently the opportunity that innovation will alter rapidly and the item will be obsolete. Additionally alongside buying the watch, the purchaser must have probably the most recent form of the IPhone all together for the gadget to be good, this constrains the market of individuals purchasing the item. While the Apple watch may convey a great deal of emblematic, and expressive worth, there are still a ton of dangers and costs joined to the item. The relationship that exists among advertising, and client esteem is obvious. Associations know that reasonable advertising needs to include something other than limited time publicity. It should be entwined with providingâ real incentive to clients. Preceding the genuine arrival of the Apple watch, the brand has had the option to discover a harmony between utilizing enormous scope advertisements on TV just as high class magazines to pick up consideration and to invoke enthusiasm from general society, while as yet teaching shoppers on the uncapped highlights and capacities that the watch has. Woodruff (1997) implies client esteem having since quite a while ago went about as an indispensable guideline inside advanced showcasing as a way to pick up consumer loyalty, yet brand steadfastness too. Associations utilize various ways of thinking of showcasing as an approach to find what the customers’ needs and needs are, t

Cellular Networks Example For Free - Free Essay Example

Introduction Computers and computer networks have changed the way in which we live, run our lives, communicate with each other and the way we work and produce what makes every commercial organisation function and reach success within its field, and in the same time, continue on the path of that success. The computers as stand-alone machines, or as separated ones, are nothing more than advanced computing machines, but what was required in reality is a way to link all the computers with each other and to allow users to have simultaneous access to databases and information; and this is why networks had to be created. Tanenbaum (2003, p.2) explains this fact by stating that â€Å"The merging of computers and communications has had a profound influence on the way computer systems are organized. The concept of the ‘computer centre as a room with a large computer to which users bring their work for processing is now totally obsolete. The old model of a single computer serving all of the organizations computational needs has been replaced by one in which a large number of separate but interconnected computers do the job. These systems are called computer networks.† The main principle behind Computer networking is the communication between two or more computer systems. Computers within a network might be close to one another (such as the case with Bluetooth for example) or hundreds of kilometres away from each other (through the Internet). The first important step in this field came in 1984, when a completely digitalised, circuit-switched telephony system was introduced; this system was called ISDN; which stands for Integrated Services Digital Network for voice and non-voice data. After that, BellCore started developing the standard for the Synchronous Op tical Network (SONET), and by the end of the 1980s, Local Area Networks (LAN) appeared as effective method of transferring data between a number of local computers, which led telephone companies replaces all its analogue multiplexing with digital multiplexing. But it is also essential to point out the element of the Internet; this international linked network, composed of servers and clients all over the world, encouraged the changes in both information technology and mobile computing, and this is why we find most of the indications, whenever we face a new product or application, referring to its characteristics in what concerns wireless connection, Bluetooth link, infrared, and much more. Raidl (2003, p.199) states that â€Å"mobile cellular networks are by far the most common of all public wireless communication systems. One of the basic principles is to re-use radio resources after a certain distance.† Walters and Kritzinger (2004) refer to the fact that mobile technology has turned to become one of the fastest, if not the fastest, growing field in the telecommunications industry. To give a clearer idea about the change brought to the world and to every one of us, we can refer to the comments of Furht and Ilyas (2003), as they state that â€Å"just a few years ago, the only way to access the Internet and the Web was by using wireline desktop and laptop computers. Today, however, users are traveling between corporate offices and customer sites, and there is a great need to access the Internet through wireless devices. The wireless revolution started with wireless phones and continued with Web phones and wireless handheld devices that can access the Internet† Types of network Computer networks can vary according to the purpose for which they were created and depending on the area they are supposed to cover geographically. Computer networks can be one of the following: 1) LAN (Local Area Network) is â€Å"a small interconnection infrastructure that typically uses a shared transmission medium. Because of such factors as the volume of traffic, the level of security, and cost, the network structure in a local area network can be significantly different from that for a wide area network.† And â€Å"LAN is used for communications in a small community in which resources, such as printers, software, and servers, are shared. Each device connected to a LAN has a unique address. Two or more LANs of the same type can also be connected to forward data frames among multiple users of other local area networks† (Mir, 2007, p.102). 2) WAN (Wide Area Network) is â€Å"spans a large geographical area, often a country or continent. It contains a c ollection of machines intended for running user (i.e., application) programs† (Tanenbaum, 2003, p.19). 3) CAN (Campus Area Networks) â€Å"are the enterprise networks that serve number of related structure, as in a large company or a college campus.† Lehtinen, Gangemi, Gangemi Sr, and Russel, 2006, p.182). 4) MAN (Metropolitan Area Network) which â€Å"covers a city. The best-known example of a MAN is the cable television network available in many cities† (Tanenbaum, p.18). 5) HAN (Home Area Network) is â€Å"the connection of a number of devices and terminals in the home on to one or more networks which are themselves connected in such a way that digital information and content can be passed between devices and any access ‘pipe to the home† (Turnbull Garrett, 2003, p.46). Cellular networks In their description of the first cellular radio networks in history, Walters and Kritzinger (2004) state that â€Å"in 1946, the first car-based telephone was set up in St. Louis, Missouri, USA. The system used a single radio transmitter on top of a tall building. A single channel was used, therefore requiring a button to be pushed to talk, and released to listen. This half duplex system is still used by modern day CB radio systems utilized by police and taxi operators. In the 1960s, the system was improved to a two-channel system, called the improved mobile telephone system (IMTS) Cellular radio systems, implemented for the first time in the advanced mobile phone system (AMPS), support more users by allowing reuse of frequencies. AMPS is an analogue system, and is part of first generation cellular radio systems.† Even though it has become one of the most common and popular means of communication between people in the last years, cellular networks still have no spe cific definition; â€Å"Cellular communications has experienced explosive growth in the past two decades. Today millions of people around the world use cellular phones. Cellular phones allow a person to make or receive a call from almost anywhere. Likewise, a person is allowed to continue the phone conversation while on the move. Cellular communications is supported by an infrastructure called a cellular network, which integrates cellular phones into the public switched telephone network† (Zhang and Stojmenovic, 2005, p.654). This difficulty in finding a definition is due to the fact that there are different technologies and networking methods used within the frame of cellular networks. Frantz and Carley (2005, p.5) explain that â€Å"cellular networks are a distinct and important network topology. Although there is a growing body of work referring to cellular networks, there is no complete formal definition. However, there are several papers that seek to describe c haracteristics of cellular networks. Cellular networks are a critical topology to formally characterize, in part, as they are thought to be a common form for covert networks.† Yet, it is possible to find some kind of an explanation of such networks and how they operate: â€Å"Cellular networks use a networked array of transceiver base stations, each located in a cell to cover the networking services in a certain area. Each cell is assigned a small frequency band and is served by a base station. Neighbouring cells are assigned different frequencies to avoid interference. However, the transmitted power is low, and frequencies can be reused over cells separated by large distances† (Mir, 2006 p.42). A cellular network, for it to be considered a functional type of communication network, relies â€Å"on relatively short-range transmitter/ receiver (transceiver) base stations that serve small sections (or cells) of a larger service area. Mobile telephone users co mmunicate by acquiring a frequency or time slot in the cell in which they are located. A master switching centre called the ‘mobile transport serving office (MTSO) links calls between users in different cells and acts as a gateway to the PSTN† (Muller, 2003, p.50) Each cellular network is composed of what is can be referred to as Cells; which are defined by Frantz, and Carley, (2005) as â€Å"a distinct subgroup of actors within a larger cellular network. The presence of at least one cell is fundamental to a networks distinction of being cellular—without at least one cell, a network is not cellular. Empirically, a cell often consists of relatively few actors and has a distinct topology that is effortless to identify visually. The actors in a cell can be partitioned into two distinct but intertwined subgroups, namely the cell-core and the cell-periphery.† Muller (2003) explains that there are no specific sizes for cells within a cellular network, th is is due to the fact that there are many factors that interfere in this element and according to the surrounding environment and obstacles can the cells size be determined: â€Å"Cell boundaries are neither uniform nor constant. The usage density in the area, as well as the landscape, the presence of major sources of interference (e.g., power lines, buildings), and the location of competing carrier cells, contributes to the definition of cell size. Cellular boundaries change continuously, with no limit to the number of frequencies available for transmission of cellular calls in an area. As the density of cellular usage increases, individual cells are split to expand capacity. By dividing a service area into small cells with limited-range transceivers, each cellular system can reuse the same frequencies many times.† According to Muller (2003), a cellular network is composed also of a Master Switching Centre which â€Å"operates similar to a telephone central office and provides links to other offices. The switching centre supports trunk lines to the base stations that establish the cells in the service area. Another component is the transmission channels which are, in most cases, two kinds of channels; a control channel and a traffic channel. And, of course, to close the circle within this network, a cellular phone is needed; â€Å"cellular telephones incorporate a combination of multi-access digital communications technology and traditional telephone technology and are designed to appear to the user as familiar residential or business telephone equipment.† During their evolution and continuing enhancement, cellular networks went through consecutive levels of development; each of them added more power and functionality to the previous one. Zhang and Stojmenovic (2005, p.654) explain that cellular networks have had three stages that are called generations. The first of those generations is analogue in nature. Then, when more cel lular phone subscribers needed to be connected and function simultaneously, digital TDMA (time division multiple access) and CDMA (code division multiple access) technologies appeared and were put to work; and this was the second stage or what is known as the second generation (2G) which was necessary in order to increase the capacity of the cellular network. â€Å"With digital technologies, digitized voice can be coded and encrypted. Therefore, the 2G cellular network is also more secure.† With the high importance of applications related to the Internet and their continuous growth, many users required more of the their cellular devices. Then the third generation (3G) arrived. 3G â€Å"integrates cellular phones into the Internet world by providing high speed packet-switching data transmission in addition to circuit-switching voice transmission. The 3G cellular networks have been deployed in some parts of Asia, Europe, and the United States since 2002 and will be wi dely deployed in the coming years.† There are some expectations regarding the future for what concerns the fourth generation wireless networks: â€Å"These will evolve towards an integrated system, which will produce a common packet-switched (possibly IP-based) platform for wireless systems, offering support for high-speed data applications and transparent integration with the wired networks† (Nicopolitidis, Obaidat, Papadimitriou and Pomportsis, 2003). Cellular networks make use of certain protocols in order to make communication easier between various entities within the limits of the network. A protocol of communication can be defined as a group of rules which correspond to messages that two or more entities communicate between each other within a network. Protocols used for cellular networks are included within the standard which is covering the service. The first and most popular standard for mobile phones is GSM (Global System for Mobile communications). Other standards are CDMA and TDMA. Another important point concerning cellular networks is what can be called Location Management, which is essential for the network to monitor every registered mobile stations location so that the mobile station can be able to connect to the network upon request. It is important to note the similarities between cellular networks and Wireless LANs, but it is also worthwhile noticing the differences between the two: â€Å"Goals for third-generation wireless communication, enunciated in the early 1990s by the International Telecommunications Union Task Group IMT-2000, focused on the first two criteria, bit rate and mobility. Third-generation systems should deliver 2 Mbps to stationary or slowly moving terminals, and at least 144 kbps to terminals moving at vehicular speeds. Meanwhile, WLAN development has confined itself to communications with low-mobility (stationary or slowly moving) terminals, and focused on high-speed data transmission. The relationship of bit rate to mobility in cellular and WLAN systems has been commonly represented in two dimensions† (Furht and Ilyas, 2003, p.33). Wireless data applications With the continuous growth of mobile devices, different services were created in order to widen the range of the functionality of those devices. For such devices to be able to use the newly offered services, specific types of applications had to be created and deployed or installed on the mobile device, may it be a cell-phone, PDA, or a notebook computer. â€Å"Wireless data services use a mix of terrestrial and satellite-based technologies to meet a wide variety of local (in building or campus settings), metropolitan, regional, national, and international communication needs A number of wireless data applications, in fact, are being designed with fixed users in mind† (Office of Technology Assessment, 1995). To be able to understand how wireless data applications work, it is necessary to have a comprehensive view concerning their delivery methods; as a matter of fact, there are two main delivery methods: â€Å"There are two fundamental information delivery methods f or wireless data applications: point-to-point access and broadcast. In point-to-point access, a logical channel is established between the client and the server. Queries are submitted to the server and results are returned to the client in much the same way as in a wired network. In broadcast, data are sent simultaneously to all users residing in the broadcast area. It is up to the client to select the data it wants† (Zomaya, 2002) Wireless data applications can be divided into two main groups: Messaging and Remote Access. â€Å"Messaging applications can generally tolerate low throughput and long transmission delays. Electronic mail (e-mail) often fits this category, but not always, messages with attached files may strain the capacity of wireless messaging networks,† then there is Remote access which is required to allow access to the resources and services of a network from outside the geographical barriers of the physical establishment of that network (Brods ky, 1997). Conclusion Throughout this paper, understanding the information presented within it fully, it is accurate to state that a cellular network is definable correctly by presenting the following: â€Å"We define a cellular network as a single-component and undirected network of actors and their relationships, strictly consisting entirely of actors who are members of a specific cell, as previously defined; thus a network in which all actors are a member of a cell. For a network to be considered cellular, these conditions must be met: (a) the ties making up the relations in the network may only be undirected, (b) the network consists of a single component, e.g., there are no isolate actors, and (c) the network consists solely of cell subgroups that are connected via spanning ties, e.g., there are no actor in the network who is not a member of a cell subgroup† (Frantz and Carley, 2005, p.10) As for wireless data applications, in 1997 Brodsky stated that if such application are to becom e widespread and popular exactly as the simple mobile phones were in the end of the 1990s, users should become â€Å"readily and reliably send and receive data over paging, cellular and PCs†. And as we can see today, that phase is exactly what we experience today; ten years after the author wrote those words. Reference List Brodsky, I. (1997).
