Shared memory MIMD architecture

Introduction to MIMD Architectures:Multiple direction watercourse, multiple informations watercourse ( MIMD ) machines have a figure of processors that function asynchronously and independently. At any clip, different processors may be put to deathing different instructions on different pieces of informations. MIMD architectures may be used in a figure of application countries such as computer-aided design/computer-aided fabrication, simulation, mold, and as communicating switches. MIMD machines can be of either shared memory or distributed memory classs. These categorizations are based on how MIMD processors entree memory. Shared memory machines may be of the bus-based, drawn-out, or hierarchal type. Distributed memory machines may hold hypercube or mesh interconnectedness strategies.MIMDA type of multiprocessor architecture in which several direction rhythms may be active at any given clip, each independently taking instructions and operands into multiple treating units and runing on them in a coincident manner. Acronym for multiple-instruction-stream.multiple-data-stream.Bottom of Form( Multiple Instruction watercourse Multiple Data watercourse ) A computing machine that can treat two or more independent sets of instructions at the same time on two or more sets of informations. Computers with multiple CPUs or individual CPUs with double nucleuss are illustrations of MIMD architecture. Hyperthreading besides consequences in a certain grade of MIMD public presentation every bit good. Contrast with SIMD. In calculating, MIMD ( Multiple Instruction watercourse, Multiple Data watercourse ) is a technique employed to accomplish correspondence. Machines utilizing MIMD have a figure of processors that function asynchronously and independently. At any clip, different processors may be put to deathing different instructions on different pieces of informations. MIMD architectures may be used in a figure of application countries such as computer-aided design/computer-aided fabrication, simulation, mold, and as communicating switches. MIMD machines can be of either shared memory or distributed memory classs. These categorizations are based on how MIMD processors entree memory. Shared memory machines may be of the bus-based, drawn-out, or hierarchal type. Distributed memory machines may hold hypercube or mesh interconnectedness strategies.Multiple Instruction – Multiple DataMIMD architectures have multiple processors that each execute an independent watercourse ( sequence ) of machine in structions. The processors execute these instructions by utilizing any accessible informations instead than being forced to run upon a individual, shared informations watercourse. Hence, at any given clip, an MIMD system can be utilizing as many different direction watercourses and informations watercourses as there are processors. Although package processes put to deathing on MIMD architectures can be synchronized by go throughing informations among processors through an interconnectedness web, or by holding processors examine informations in a shared memory, the processors ‘ independent executing makes MIMD architectures asynchronous machines.Shared Memory: Bus-basedMIMD machines with shared memory have processors which portion a common, cardinal memory. In the simplest signifier, all processors are attached to a coach which connects them to memory. This apparatus is called bus-based shared memory. Bus-based machines may hold another coach that enables them to pass on straight with one another. This extra coach is used for synchronism among the processors. When utilizing bus-based shared memory MIMD machines, merely a little figure of processors can be supported. There is contention among the processors for entree to shared memory, so these machines are limited for this ground. These machines may be inc rementally expanded up to the point where there is excessively much contention on the coach.Shared Memory: ExtendedMIMD machines with extended shared memory effort to avoid or cut down the contention among processors for shared memory by subdividing the memory into a figure of independent memory units. These memory units are connected to the processsors by an interconnectedness web. The memory units are treated as a incorporate cardinal memory. One type of interconnectedness web for this type of architecture is a crossbar shift web. In this strategy, N processors are linked to M memory units which requires N times M switches. This is non an economically executable apparatus for linking a big figure of processors.Shared Memory: HierarchicalMIMD machines with hierarchal shared memory usage a hierarchy of coachs to give processors entree to each other ‘s memory. Processors on different boards may pass on through inter nodal coachs. Buss support communicating between boards. We us e this type of architecture, the machine may back up over a 1000 processors. In calculating, shared memory is memory that may be at the same time accessed by multiple plans with an purpose to supply communicating among them or avoid excess transcripts. Depending on context, plans may run on a individual processor or on multiple separate processors. Using memory for communicating inside a individual plan, for illustration among its multiple togss, is by and large non referred to as shared memoryIN HARDWAREIn computing machine hardware, shared memory refers to a ( typically ) big block of random entree memory that can be accessed by several different cardinal treating units ( CPUs ) in a multiple-processor computing machine system. A shared memory system is comparatively easy to plan since all processors portion a individual position of informations and the communicating between processors can be every bit fast as memory entrees to a same location. The issue with shared memory systems is that many CPUs need fast entree to memory and will probably hoard memory, which has two complications:CPU-to-memory connexion becomes a constriction. Shared memory computing machines can non scale really good. Most of them have ten or fewer processors.Cache coherency: Whenever one cache is updated with information that may be used by other processors, the alteration needs to be reflected to the other processors, otherwise the different processors will be working with incoherent informations ( see cache coherency and memory coherency ) . Such coherency protocols can, when they work good, supply highly high-performance entree to shared information between multiple processors. On the other manus they can sometimes go overladen and go a constriction to public presentation.The options to shared memory are distributed memory and distributed shared memory, each holding a similar set of issues. See besides Non-Uniform Memory Access.IN SOFTWARE:In compu ting machine package, shared memory is eitherA method of inter-process communicating ( IPC ) , i.e. a manner of interchanging informations between plans running at the same clip. One procedure will make an country in RAM which other procedures can entree, orA method of conserving memory infinite by directing entrees to what would normally be transcripts of a piece of informations to a individual case alternatively, by utilizing practical memory functions or with expressed support of the plan in inquiry. This is most frequently used for shared libraries and for Execute in Place.Shared Memory MIMD Architectures:The distinguishing characteristic of shared memory systems is that no affair how many memory blocks are used in them and how these memory blocks are connected to the processors and address infinites of these memory blocks are unified into a planetary reference infinite which is wholly seeable to all processors of the shared memory system. Publishing a certain memory reference b y any processor will entree the same memory block location. However, harmonizing to the physical organisation of the logically shared memory, two chief types of shared memory system could be distinguished: Physically shared memory systems Virtual ( or distributed ) shared memory systems In physically shared memory systems all memory blocks can be accessed uniformly by all processors. In distributed shared memory systems the memory blocks are physically distributed among the processors as local memory units. The three chief design issues in increasing the scalability of shared memory systems are:Organization of memoryDesign of interconnectedness websDesign of cache coherent protocolsCache Coherence:Cache memories are introduced into computing machines in order to convey informations closer to the processor and hence to cut down memory latency. Caches widely accepted and employed in uniprocessor systems. However, in multiprocessor machines where several processors require a transcript of the same memory block. The care of consistence among these transcripts raises the alleged cache coherency job which has three causes:Sharing of writable informationsProcedure migrationI/O activityFrom the point of position of cache coherency, informations constructions can be divided into three categories:Read-only informations constructions which ne'er cause any cache coherency job. They can be replicated and placed in any figure of cache memory blocks without any job.Shared writable informations constructions are the chief beginning of cache coherency jobs.Private writable informations constructions pose cache coherency jobs merely in the instance of procedure migration.There are several techniques to keep cache coherency for the critical instance, that is, shared writable informations constructions. The applied methods can be divided into two categories:hardware-based protocolssoftware-based protocolsSoftware-based strategies normally introduce some limitations on the cachability of informations in orde r to forestall cache coherency jobs.Hardware-based Protocols:Hardware-based protocols provide general solutions to the jobs of cache coherency without any limitations on the cachability of informations. The monetary value of this attack is that shared memory systems must be extended with sophisticated hardware mechanisms to back up cache coherency. Hardware-based protocols can be classified harmonizing to their memory update policy, cache coherency policy, and interconnectedness strategy. Two types of memory update policy are applied in multiprocessors: write-through and write-back. Cache coherency policy is divided into write-update policy and write-invalidate policy. Hardware-based protocols can be farther classified into three basic categories depending on the nature of the interconnectedness web applied in the shared memory system. If the web expeditiously supports broadcast medium, the alleged Snoopy cache protocol can be well exploited. This strategy is typically used in individual bus-based shared memory systems where consistence commands ( invalidate or update bids ) are broadcast via the coach and each cache ‘snoops ‘ on the coach for incoming consistence bids. Large interconnectedness webs like multistage webs can non back up airing expeditiously and hence a mechanism is needed that can straight frontward consistence bids to those caches that contain a transcript of the updated information construction. For this intent a directory must be maintained for each block of the shared memory to administrate the existent location of blocks in the possible caches. This attack is called the directory strategy. The 3rd attack attempts to avoid the application of the dearly-won directory strategy but still supply high scalability. It proposes multiple-bus webs with the application of hierarchal cache coherency protocols that are generalized or extended versions of the individual bus-based Snoopy cache protocol. In depicting a cache coherency protocol the undermentioned definitions must be given:Definition of possible provinces of blocks in caches, memories and directories.Definition of bids to be performed at assorted read/write hit/miss actions.Definition of province passages in caches, memories and directories harmonizing to the bids.Definition of transmittal paths of bids among processors, caches, memories and directories.Software-based Protocols:Although hardware-based protocols offer the fastest mechanism for keeping cache consistence, they introduce a important excess hardware complexness, peculiarly in scalable multiprocessors. Software-based attacks represent a good and competitory via media since they require about negligible hardware support and they can take to the same little figure of annulment girls as the hardware-based protocols. All the software-based protocols rely on compiler aid. The compiler analyses the plan and classifies the variables into four categories:Read-onlyRead-only for any figure of procedures and read-write for one procedureRead-write for one procedureRead-write for any figure of procedures.Read-only variables can be cached without limitations. Type 2 variables can be cached merely for the processor where the read-write procedure tallies. Since merely one procedure uses type 3 variables it is sufficient to hoard them merely for that procedure. Type 4 variables must non be cached in software-based strategies. Variables demonstrate different behaviour in different plan subdivisions and hence the plan is normally divided into subdivisions by the compiler and the variables are categorized independently in each subdivision. More than that, the compiler generates instructions that control the cache or entree the cache explicitly based on the categorization of variables and codification cleavage. Typically, at the terminal of each plan subdivision the caches must be invalidated to guarantee that the variables are in a consistent province before get downing a new subdivision. shared memory systems can be divided into four chief categories:Uniform Memory Access ( UMA ) Machines:Contemporary unvarying memory entree machines are small-size individual coach multiprocessors. Large UMA machines with 100s of processors and a shift web were typical in the early design of scalable shared memory systems. Celebrated representatives of that category of multiprocessors are the Denelcor HEP and the NYU Ultracomputer. They introduced many advanced characteristics in their design, some of which even today represent a important milepost in parallel computing machine architectures. However, these early systems do non incorporate either cache memory or local chief memory which turned out to be necessary to accomplish high public presentation in scalable shared memory systemsNon-Uniform Memory Access ( NUMA ) Machines:Non-uniform memory entree ( NUMA ) machines were designed to avoid the memory entree constriction of UMA machines. The logically shared memory is physically di stributed among the treating nodes of NUMA machines, taking to distributed shared memory architectures. On one manus these parallel computing machines became extremely scalable, but on the other manus they are really sensitive to data allotment in local memories. Accessing a local memory section of a node is much faster than accessing a distant memory section. Not by opportunity, the construction and design of these machines resemble in many ways that of distributed memory multicomputers. The chief difference is in the organisation of the address infinite. In multiprocessors, a planetary reference infinite is applied that is uniformly seeable from each processor ; that is, all processors can transparently entree all memory locations. In multicomputers, the reference infinite is replicated in the local memories of the processing elements. This difference in the address infinite of the memory is besides reflected at the package degree: distributed memory multicomputers are programmed on the footing of the message-passing paradigm, while NUMA machines are programmed on the footing of the planetary reference infinite ( shared memory ) rule. The job of cache coherence does non look in distributed memory multicomputers since the message-passing paradigm explicitly handles different transcripts of the same information construction in the signifier of independent messages. In the shard memory paradigm, multiple entrees to the same planetary information construction are possible and can be accelerated if local transcripts of the planetary information construction are maintained in local caches. However, the hardware-supported cache consistence strategies are non introduced into the NUMA machines. These systems can hoard read-only codification and informations, every bit good as local informations, but non shared modifiable informations. This is the separating characteristic between NUMA and CC-NUMA multiprocessors. Consequently, NUMA machines are nearer to multicomputers than to other shared memory multiprocessors, while CC-NUMA machines look like existent shared memory systems. In NUMA machines, like in multicomputers, the chief design issues are the organisation of processor nodes, the interconnectedness web, and the possible techniques to cut down distant memory entrees. Two illustrations of NUMA machines are the Hector and the Cray T3D multiprocessor.www.wikipedia.comhypertext transfer protocol: //www.developers.net/tsearch? searchkeys=MIMD+architecturehypertext transfer protocol: //carbon.cudenver.edu/~galaghba/mimd.htmlhypertext transfer protocol: //www.docstoc.com/docs/2685241/Computer-Architecture-Introduction-to-MIMD-architectures

Categorical imperative Essay

Abstract Immanuel Kantis one of the most influential philosophers in the history of the Western philosophy. His contribution two metaphysical epistemology, ethic, and aesthetics have had a profound impact on almost every philosophical movements that followed him. Kant believe that, in knowledge originated in our senses and that the mind is a blank slate, that becames populated with ideas by its interaction with the world. Kant Influence on Criminal Justice In New World Encyclopedia (2013) states that Immanuel Kant was born, and spent the majority of his life in the city Konigsberg , the capital of East Prussia. His father was a German craftsman. His parents baptized him as Emanuel Kant, which he later changed to Immanuel after learning Hebrew. He attended the Collegium Fridiciaum at the age of eight. After eight years of study in there, he went to the University of Konideberg where he studied philosophy and mathematics. The death of his father affected him greatly, however, with the support of a friend he earned and received his doctrine in 1756. After befriending the English merchant Joseph Green, who instilled in Kant arespect for living in accordance to strict observed rules of behavior, he began to live a very regulated life. For the remainder of his life Kant remain unmarried and owned only one piece of art in his household, advocating the absence of passion in flavor of logic. He never left Prussia and rarelyventured out oh his hometown. He was a respected and very competitive university professor for most of his life. Historical repute did not come to him until he was in his late 50’s. In 1740, he went to the University to study philosophers Gottfried Leinbniz and Christian Wolff under the tutelage of Martin Knutsen , who was familiar with the development of British philosophy and science. It is there that Knutsen introduced Kant to a new system of mathematics by Sir Isaac Newton (1997). In 1746, Kant wrote the paper on measurements of reflecting Leibniz’s influence. In 1755 he then became a private lecture at the University, and while there he published â€Å"Inquiry into the Distinctness of the Principles of Natural Theology and Morals† in which he examines the problem of having a logical system of philosophy that was connected with the world of natural philosophy, a concern typically of the period. In that same year he published a piece titled â€Å"In Dreams of a spirit-seer Elucidated by Dreams of Metaphysics†. For the next 10 years, he work solely on the architecture of his own philosophy. Then in 1781 he released the † Critique of Pure Reason†, This work was to become the most influential, widely cited, and distributed work in Western philosophy. He then followed with his work † Ground of Metaphysic of Morals†. Then in 1788 who wrote † Critique of Practical Reason† then he finished and perfected his work on † Critique of Judgment† (2005). Almost all of his work was attacked and criticize seriously, practically his ideas on category, or, the place of free will and determinism, and weather we are capable of processing true and corrected knowledge of eternal reality. In his life Kant wrote a number of lesser known essays on history, politics and the application of philosophy of life. When he died in 1804, he was working on an incomplete manuscript that has since been published as† Opus Postmum†. Immanuel Kant had an interesting system of beliefs. It’s based on the beliefs , that reasoning is the final authority for morality. Actions of any sort, he believed, must be done from a sense of duty dictated by reason, and no action the form for expediency for solely in obedience to the law or custom can be regarded as moral. Moral , according to Kant, is apt done for the right reasons. Kant what are you that to make a promise for wrong reason is not moral, in other words, you might as well not make the promise. You must have a duty, or, correct moral inside of you, and for your folly of lying, your actions would only give you away. Kant described in common command given by reason: the hypothetical imperative, which dictates a given course of action to reach a specific end; and the categorical imperative, which dictates a course of action that must be followed because of moral rightness and necessity. It is also stated that Kant believe it to be irrational to perform in action if the action maxim contradicted itself once made into a universal law of nature (2013). In other words, before you act, you must decide what rules would be following if you were to act, whether you would are willing for rules to be followed by everyone. If you are willing to universalize the act, it must be moral; its not, then the act become morallyimpermissible. Kant police not the welfare of each individual should probably be regarded as in and itself, as stated in † Formula of the End† (2013) in itself: act in such a way that you always treating humanely weather in your own person or in the person of another, never simply as a means, but always at the same time as an end. Kant believed that the moral rules are without exception. Therefore, it is wrong to kill all situations even the case of self defense. This thought comes from the Universal Law Theory (2010). Since we never wanted to in order to become a universal law then it must be a moral in all situations. For what Kant’ s describe in his rules of absolut Killing, according to Kant, could never made universal law, therefore it is wrong and each in every situation. There are never any extentuating circumstance, such as self defense. Is out current laws were left to Kant , people would be prosecuted for everything since there is no extentuating circumstances. Kant cateorical imperative is a tri-dynamic statement of philosophical thought: (1) Actso that the maximum of your will always hold, at the same time as principles is stablished universal law. (2) Acts so as to treat everything with the upmost humanity, including your own person as well as everyone else, and always as an end but never as a mean. (3) Act according to maxim as a universal legislative member of a mere potential Kingdom of ends (2010). In other words Kant’ s argument that particular actions require constant thoughts for roll covering it, that the rule is acceptable for universal action should be adopted, its not, then it should be rejected. In order to understand whether or not actions follow Kant’ s category imperative, we must prescribe post normal what we wish to be universal laws. The norms that create to value judgement are based on issues involving justice between a few people or groups or nation. He further states that thought his cognitive development of peaceful interaction of building of Republic, we can create a community as natural result of unimpeded development of human facilities (1997). Kant states that because we must believe in all the things develop to the fullest capacity, then we could the theorize that, in summary, through congnitive processes we can create community, based on moral (ethical) action towards every person, thereby creating universal ethic throughout the community.

Substance use Essay Example | Topics and Well Written Essays - 250 words

Substance use - Essay Example Research confirms that during the 8-year study period, teens that call for help from poison control rose by a shocking 76%. Although amphetamines are taken for general cures such as headache and body pain, they can be abused easily. Since amphetamines act as stimulants and can be addictive. The modifications that occur in the brain chemistry by abusing this drug can lead not only to addiction but the need to have continual use of this drug. This cause and effect relationship can no doubt create an amphetamine addiction. An individual with this addiction will engage in a criminal activity by either hiding their drug use or stealing it to fulfill their addiction. This is clearly detrimental to society as it leads to an economic burden of society paying additional taxes. Amphetamines are usually listed in schedule II of controlled substances due to various reasons. One of the key reasons is the fact that amphetamines have a medium severity for high capacity for abuse but can be utilized for medical use. Other drugs that are also classified in schedule II consist of: marijuana, heroin, and AMT. Consequently, the schedule I list differs from schedule II since drugs such as heroin; LSD and marijuana are highly abusive and cannot be used for medical purposes.

Margin of error therefore is a radius of confidence where a statistical data from a survey relies on. This means that the marginal error is a center of information in which case there might be a higher or lower relative information. When a sample percentage is presented, a slot can be reduced on the actual value of 100% to 97% so that the 3% becomes the value of the error due to many procedures. The company can conduct a probability sampling. In this regard, each member of the target has a non-zero probability of inclusion in the sample. Here the information is unbiased because the information produced would relatively be expected to adhere to strict statistical analysis to avoid bigger errors.

Mummers Parade Essay Example | Topics and Well Written Essays - 2500 words

Mummers Parade - Essay Example Historians believe that Mummers Parade is the only tradition that has lasted for a long time running fork festival in the United States. The parade usually consists of thousands of performers who spend months developing and rehearsing so that it will be enjoyable. They build costumes and scenery and make the parade to be perfect preparing for entire day moving their way up Broad Street where day drinking marks the event. For those who do not go for the parade choose to keep drinking the whole night and in the morning while others use the New Year Eve to move to other countries for leisure. People usually come to the parade by train, bike and others on foot carrying glasses and thermoses of beer so that they can wear their costumes which will depict foreign cultures. Some people who do not like to be associated with racism do not let their children to go to the parade since they say that the parade is a racist tradition that is usually carried from one generation to the next despite t he parade being banned. The participant of the parade dress like a person or a thing that they are not, where they colour themselves and others depicts creatures which are colourful though they are white men they present simplistic cartoons which depicts foreign people and their culture showing that the parade is usually prepared to mark racist agendas in each and every year. During the 18th and 19th century   the slaves who were transported to United States and later employed in the plantation used to play instruments in the plantations.

Dualism Research Paper Example | Topics and Well Written Essays - 2500 words

Dualism - Research Paper Example Are medical researchers within their rights to experiment on animals if their research helps cure diseases? Do animal rights properly belong to the realm of philosophy and pedagogy, or is it a matter for the courts? At the crux of the issue is the meaning of â€Å"sentience.† Does feeling (i.e. physical sensation) equate to intelligence? The main thrust of this paper is to argue that the ability to feel pain establishes a minimum ethical criterion for not experimenting on animals and, if by extension, feelings and other â€Å"emotions† are deemed to be present, then animal protection should acquire the force of law. Aristotle wrote that animals meet this minimum criterion, arguing that they are endowed with perceptive sensitivity, â€Å"which appears inherent in all animals, for they have an innate power, which (is called) sensible perception†¦Ã¢â‚¬  (Aristotle, 354). But when it came to this sensitivity, Aristotle said, not all animals are created equal. He said that â€Å"sense being inherent Name 2 in some animals, a permanency of the sensible object is engendered, but in others it is not engendered,† as would be the case with insects, for instance (Aristotle, 354). Descartes made a similar distinction, but one which drew on man’s supposedly divine nature, asserting that while animals wield an intelligence that allows them to carry out basic tasks, such as finding shelter, this intelligence â€Å"is of a significantly inferior type to the rational intelligence of man, which comes from his soul† (Kang, 117). Ultimately, Descartes decided that animal intelligence cannot be compared to that of humans, because animals are unable to reason or communicate verbally. Nevertheless, whatever the limits of animal consciousness might be, countless theories have been developed to support the validity of animal intelligence. Physicalist and Neurofunctionalist – philosophical approaches Physicalism postulates that consciousn ess canbe identified with neuron activity, a position that allows for the possibility that intelligence is a characteristic humans and animals share, so long as they are built upon the same â€Å"biological, chemical and physical† properties (Allen, 2010). Such an approach also claims that questions about the relative intelligence of different species becomes â€Å"trivial† â€Å"once neuroscientists have carried out the non-trivial task of determining the physiological basis of consciousness in animals for which no reasonable doubt of their consciousness can be entertained† (Allen, 2010). Neurofunctionalism considers the existence of neural cortex activity in primates as â€Å"the most plausible candidate for being the neural correlate of phenomenal consciousness in these species† (Allen, 2010). In â€Å"On a Confusion About a Function of Consciousness,† N. Block associates phenomenal consciousness with brain processes in certain higher-level perc eptual representations. â€Å"Since the evidence for Name 3 such processes is at least partially derived from animals, including other primates and rats, (Block’s) view is supportive of the that phenomenal consciousness is found in some nonhuman species (presumably most mammals)† (Allen, 2010). Other â€Å"first-order† theories take a more direct line, including representationalism, which insists that an animal’s ability to perceive its surroundings equates to conscious awareness. Aristotle and Locke took a

Role of Parents Diminishes from Generation to Generation Essay

Role of Parents Diminishes from Generation to Generation - Essay Example Children no more need their parents for guidance and supervision. All they need to do is click on Google to know whether a decision is right or wrong, to know the consequences of bad career choice, and to know if they need to correct their diet. Parents’ role has diminished. No doubt, this is a tragedy. Nothing can substitute the ultimate love and care that parents can give to their child. Internet does not pray for us. Media does not feed us. Movies do not pick us up when we fall down. But getting ahead of this emotional debate, let’s ponder upon why parents’ role has diminished, and what the aftermath is. Helena Norberg-Hodge (632) writes that today, teenagers are ashamed of their traditional ways of living, and to be precise, they are ashamed of their parents. They do not admire their parents anymore; instead, they appreciate all those chic-clothed classy actors and actresses they see on television. Their parents have become old-fashioned for them. They do not like their parents asking them to choose a way of life that involves working in the fields and getting their hands dirty for little or no money, and certainly no glamour† (Norberg-Hodge 632, para.3). ... Apparently, we are connecting to the world through online social networks, like Facebook and Orkut, but what happens in real? We are disconnecting from real life. This disconnection diminishes the role of significant others in children’s lives, especially that of the parents. This has given rise to the big generation gap, accompanied with scary communication barriers. â€Å"We tried to make our conversation seem like more than an interview†, writes Rodriguez (201), telling about his experience when he talked to his mother on Christmas vacation. Why, today, parents and children need to put in effort to bring some life to their conversation? Why does it not come up naturally, with care and concern? This is because children are emotionally distant from their parents. Parents, themselves, are too busy nowadays, and they provide their children with expensive electronic gadgets, multichannel cables, LCD televisions, and computers, which children spend most of their time with. They have ready-made food available to them at McDonalds, Pizza Hut, and KFC. They do not need their mother’s good old recipe driven healthy food anymore. They absorb knowledge from what they see on media channels. They learn everything before parents even get the chance to tell them. Mothers wait for the right menstrual age of their daughters to tell them about it, and daughters already know it. Fathers wait for their boys to get big enough to be told about safe sex, and the boys already know it. It is all around them- the information, the knowledge, the statistics, the facts and figures, the good consequences and the bad ones. Then, why would they need their parents anymore? Today’s age has made them
