Nursing Essay Example | Topics and Well Written Essays - 2750 words

Nursing - Essay Example The patient opened his bowels most days with a small, hard constipated result, which did not relief the abdominal pain. The patient had been unable to eat solid food, surviving only on nutritional supplement drinks and had lost one and half stone in weight. Eventually, after further investigation the patient was diagnosed with inflammation of the colon and it was decided to perform an elective surgery by performing an ileomstomy leaving the wound on the patient’s left side. After the operation on the ward, the patient was told that the colostomy would be non reversible. I inquired how he felt about it. He replied that he had felt physically and psychologically prepared for the surgery. I felt that this was a positive sign; even through the surgery resulted in him receiving a stoma. In addition the patient had a relatively smooth post-operative recovery. Diet right after surgery should consist of liquids that are high in protein. After discharged Benign discharged home after fi fteen day and then referred to the local stoma nurse for follow-up.

This paper approves that Benign discharged home after fifteen day and then referred to the local stoma nurse for follow-up. The clinic provided the opportunity to look at alternative appliances owning to frequent leak, but a satisfactory one-pice with flange extenders was agreed which worked well. A surgical procedure that creates a hole or stoma on the abdomen and brings out the end of the colon during the stoma for the reasons of stool expulsion, a colostomy bag is attached to the stoma for stool compilation. A colostomy is normally done due to problems within the colon, such as colon cancer and intestinal trauma, Patients with colostomies should consume food that prevents complications and enables the stoma to heal. This essay makes a conclusion that Multidisciplinary teams are groups of professionals from different fields of medicine who come together to provide comprehensive assessment and consultation in medical cases. The multi disciplinary team were involved in the ileomstomy surgery since more than one health professional was required to assist in the operation. The MDT combines mutually individuals who have expertise in various areas of medicine and care, and typically meet as frequently as on weekly basis to talk about the diagnosis, treatment and care of individual patients. The health professionals included in the multi disciplinary team are a colon and rectal surgeon, a general surgeon, a specialized stoma therapy nurse, a gastroenterologist, a histopathologist, a dietician, an enterostomal therapist, a primary nurse, a psychologist and social workers.

Debate2 Coursework Example | Topics and Well Written Essays - 750 words

Debate2 - Coursework Example Free trade arguments have in past times received support from majority of global institutions, such as the International Monetary Fund (IMF), the World Bank, and World Trade Organization (WTO). As part of the argument in this paper, it will examine how removal of trade barriers induces higher level of economic growth and efficiency within the global economy (Quinlan & Stevens 1998b). None of the countries, in recent decades, has accomplished economic success, in regard to substantial improvement in its people`s living standards, without opening up its economy and engaging in free trade with the rest of the globe. For example, trade opening together with opening economies to foreign direct investment, constitute an important element in the growth of economies of East Asia. The average import tariff in these economies has fallen to 10 percent from 30 percent over the last 20 years. Several Asian countries have become more successful since they opted to participate in the global trade w hich has also helped them in attracting the bulk of direct foreign investment in developing countries as an expansion of their market. This is undoubtedly true of India and China since they both have embraced trade liberalization as well as other market-oriented reforms. China currently invests and trade with East African countries as a result of free trade agreement between the nations. Trade liberalization offers the ideal policy prescription since the economic benefits that accrue from free trade are relatively simpler to illustrate. Countries in the world are generally confronted with just two prices for goods and services within the global economy: the world prices and the domestic price. In a situation where the world price is lower than a country`s domestic price, say Brazil, then domestic consumers from Brazil will purchase the services and good offered by other international markets since they are cheaper. However, firms in Brazil can respond to the effect of free trade by seeking government support through imposing import tax or apply for investment incentives. In addition to the argument that free trade functions best in promoting efficient allocation of resources, it has also been asserted to occasion additional long-run benefits like; economies of scale, improved productivity since prices for intermediate services and goods decrease, and growth externalities via technology transfer. Economies of scale apply to industries which require a very huge volume of production prior to reaching the lowest average cost (AC). Examples of these industries are the movie and film industries of Nigeria and Hollywood. Without no doubt, such industries will hardly arise in an environment that free trade is restricted because, based on the reality that such industries definitely need large markets so as to be efficient, their market will be narrowed only to domestic market (United States, 2004). Growth externalities means the production benefits which may originate from the incorporation of recent technologies acquired by other globe`s production firms through enhanced interaction with foreign countries as a result of free trade. Therefore, free trade offers numerous opportunities for innovation and learning, which are necessary for the global economic growth and strength of international economies, than are offered by a system of closed economy or managed trade (Maddison, 2001). An example of these growth externality

Wings to Intellectual Cinema with a Mix of Excitement and Special Essay

Wings to Intellectual Cinema with a Mix of Excitement and Special Effects - Essay Example The text has an exquisite presentation of fiction and magic realism. This paper is aimed to review the short story, discuss its feasibility as a film, and explain the potential target audience. I feel that both the text and its cinematic adoption will have similar target audience. Review The text ‘A Very Old Man with Enormous Wings’ can be primarily classified under the category of magic realism. It is one of Marquez’s famous short stories written in 1955 that we find in the book Leaf Storm. The backdrop of the plot is set in a rural area. Pelayo and Elisenda is an impoverished couple who lived in a sorrowful state of extreme poverty. Their little son is badly sick. On a stormy afternoon one day, the couple finds a very old man who has huge wings attached to his body in their courtyard. When the couple tries to communicate with him, they find his language they do not understand. Pelayo locks the man in his chicken coop. From this point, the game of magic and reality begins. Magic being the arrival of the old man with wings, the reality is the manifestation of curiosity entrenched human minds. Hundreds of villagers now begin to visit the couple’s house to see the strange old man. Pelayo and Elisenda inform Father Gonzega about the man. Father Gonzega arrives and tries to communicate with the old man but fails. Marquez brings marvelous satire at this stage. Father Gonzega informs the Vatican about the old man, who in turn asks the priest to examine that whether the old man could be an angel or not. Father Gonzega acts accordingly and examines him. He finds that the old man does not know Latin, or Aramaic, is very frail, and has too many mortal features to be an angel. Father’s feedback to the Vatican leaves the Catholic Church a strange conclusion †¦ The old man is a Norwegian sailor! This satire shows that how unquestionable faith may create so much confusion that not even the bas ic elements of anomaly or wonder are distinguished. The intellectual content of the story increases along with its innovative unusualness when a young woman with human head and a body of a spider is introduced in the village. She says she had disobeyed her parents and hence she was punished by the means of such a strange transformation. In the meanwhile, Pelayo and Elisenda have become rich as they have been charging a fee from the visitors who come to see the old man in large numbers. However, with the appearance of the strange woman, visitors shift their attention to her. This is how the short lived excitement and inconsistency of human askance from one topic to another is exhibited. At the end of the story, the old man simply flies away. He had brought much fortune to the impoverished couple, but he faced unnecessary cruelty, and ultimately, negligence. Interpretation The overall message is mixed. There is religious satire that involves the Catholic Church and the power mechanism s of this institution. There are the inconsistencies of human mind and perceptions. There is a subplot of an interesting woman, who has the body of a spider. There is emotional tug of war at the end. So, the story has lots of intellectual substance. The tone is fluctuating from humor to fiction and satire to emotion. Marquez has not given any clear indication that for whom has he written this story. However, it appears to be appealing to a varied spectrum of audience. The characteristics of the story suggest that it is thought provoking, exciting, and sometimes, rather comic. Despite these qualities, it seems that too many ideas sometimes infest the plot and the developments in the text with absurdity. It is not good to

Change Management - individual Assignment Example | Topics and Well Written Essays - 2250 words

Change Management - individual - Assignment Example Moreover, constant technological innovations and globalizations results in a constantly evolving business environment. Phenomena such as the mobile adaptability and the social media have created many revolutions in business and the resultant effects is the ever increasing desire for change, and hence change management. The perspectives of managing change held by major change agents studied in my group case study Change management in any organization or work place is one of the important areas that should be taken into account for the overall change in the mode of operations. Aside from the overall change management in any workplace, we came up with perspectives in our group case study on management of change that incorporates many factors and boils down many assumptions into a simple basic pattern of thoughts. These I believe would have some implications in the future of the organization. To begin with, for the change to be effected in any organization it should start with the person al change management of the leader or the manager before it is adopted by other employees in the organization. But it is of great importance that the perspective in change management and recognition of the others points of view are paramount for them also to adopt the assumptions of their leader (Elearn Limited (Great Britain) 2007). Secondly, according to Green (2007), it is always important to think the worthiness of the change enforcement before executing it. This is because most employees tend to be more effective when allowed to finish the tasks assigned in their own unique ways. However, this is not the case in many organizations. Many of them have laid down procedures where work has to be done according to the rules of the book. For instance, in the manufacturing line, there are processes that cannot be replaced by any other way apart from the laid down procedure. Therefore, this calls for caution before adopting change. Thirdly, it is of high importance as the manager to alw ays remember that change does not occur overnight. People differ in their management styles and therefore the differences are portrayed differently. Some managers when coping with change are more methodical while some managers can adapt at a notice of a moment. Therefore, managers need to evaluate themselves and find their own way of adapting to change (Pugh 2007). Finally, our personal assumption in the management of change involves the people directly affected in all stages of the change process. This calls for teamwork in any organization or work place because mandating an employee to change and failing to involve him/her in the process of change increases the probability that they will not change. An explanation of how these assumptions impacted upon the processes and outcomes of this organizational change initiative Technological growth has secondary effect of rising up the availability and hence knowledge accountability. Furthermore, information which is easily accessible has resulted in un-foreseen scrutiny from the media and the stakeholders. Pugh & Mayle (2009) observes â€Å"that the listening ears and the prying eyes makes the failed businesses uncomfortable and thwart their endeavors†. Furthermore, it increases high pressure on the struggling executives. With the environment of the business experiencing so many changes, the organizations should adapt and adjust to be comfortable with many upcoming changes as well. Therefore, management and adaptation ability to

Cyberterrorism Essay Example for Free

Cyberterrorism Essay The term cyberterrorism was created in the mid 90’s by combining cyberspace and terrorism. The term has been widely accepted after being embraced by the United State Intelligence Community. Janczewski and Colarik describe cyberterrorism as â€Å"Premeditated, politically motivated attacks by subnational groups, clandestine agents, or individuals against information and computer systems, computer programs, and data that result in violence against non-combat targets† (Janczewski Colarik, 2005, p. 43). Cyberterrorism is a form of terrorism that uses any form of connected source to engage in attacks of information systems, incitement to violence, theft of data, and planning of terrorist attacks (Britz, 2011, p. 197). As an introduction into the topic, the following definition is key to understanding the definition: â€Å"Cyberterrorism is the convergence of terrorism and cyberspace. It is generally understood to mean unlawful attacks and threats of attack against computers, networks, and the information stored therein when done to intimidate or coercer a government or its people in furtherance of political or social objectives. Further, to qualify as cyberterrorism, an attack should result in violence against persons or property, or at least cause enough harm to generate fear. Attacks that lead to death or bodily injury, explosions, plane crashes, water contamination, or severe economic loss would be examples. Serious attacks against critical infrastructures could be acts of cyberterrorism, depending on their impact. Attacks that disrupt nonessential services or that are mainly a costly nuisance would not† (Denning, 2000). Cyberterrorism is considered an act of violence or intimidation using cyberspace. It is more complicated than simply hacking into a system to see what damage can be done; it has to stem from a motivational source such as politics, foreign government, or some other rousing source (Gross, 2003). Enemies of the U. S. are strongly motivated by hate. Hate can be a strong motivator when it comes to cyberterrorism, and just terrorism in general. When hate is the driving factor of actions, the consideration for the targeted group is very minimal, and the results of hate crimes are usually violent and gruesome acts. The FBI’s definition isn’t that far off from Denning’s. They have published three different distinct definitions of cyberterrorism: â€Å"Terrorism that†¦initiates attacks on information† – â€Å"the use of Cyber tools† – and â€Å"a criminal act perpetrated by the use of computers (Baranetsky, 2009). Most government agencies that have a response program for cyberterrorism have their own published definition of cyberterrorism. The question rises ‘why does cyberterrorism occur? ’ The answer is that the terrorist want cause specific damage to the target. There are three factors that are considered when this question is asked, the first being the fear factor. It is the most common denominator of the majority of terrorist attacks. The attackers want to create as sense of fear in individuals, groups, or societies – whomever they are targeting (Janczewski Colarik, 2005, p. 45). Perhaps a cyber example of this could be the attack of IT installations. Then there is the spectacular factor. Spectacular means that the attacks are aimed at creating direct losses or resulting in a lot of negative publicity (Janczewski Colarik, 2005, p. 45). An example of the spectacular factor at work was in 1999 when Amazon. com was closed because of a Denial of Service (DOS) attack. They suffered losses from the attack, but the worse affect was the publicity that that was received (Taylor, Calabresi, Krantz, Pascual, Ressner, 2000). The last factor is the vulnerability factor. This is simply when vulnerability of an organization is exposed (Janczewski Colarik, 2005). An example of this could be the vandalism of an organizations webpage. The importance and significance of cyberterrorism is a very debatable topic. Kim Taipale, founder and executive director for the Stilwell Center for Advanced Studies in Science and Technology Policy believes â€Å"cyberterrorism, whatever it is, is a useless term. Taipale believes that, â€Å"terrorists will use any strategic tool they can† so â€Å"cyber† terrorism is no more important then other forms (Baranetsky, 2009). The statements by Taipale are strong, and arguments could be made supporting her, and arguments could be made that go against her beliefs. It is true that terrorism is growing all over the world, and terrorists are beginning to use various outlets to threaten nations, groups, and individuals. So the case could be made stating that cyberterrorism is just an accessible outlet terrorists have, because of the access that is granted to an individual on cyberspace. In conflict with that argument is the argument that cyberspace is not monitored and policed enough, and has little to no restrictions as to what can be done in cyberspace. This is an ongoing debate that will not be discussed in this paper. Different Forms of Cyber Attacks Various types of cyber attacks are used within the terrorist aspect of cyberspace. According to the Center for Strategic and International Studies, cyberterrorism is â€Å"the use of computer networks to shut down critical infrastructure (such as energy, transportation, government operations) or to coerce or intimidate a government or civilian population† (Lewis, 2002, p. ). The most commonly used tactics used to neutralize critical infrastructure are attacks known as the Trojan horse, viruses, phishing, Denial of Service (DoS), and Direct Denial of Service attacks. The first of the types of the cyber attacks to be discussed is the Trojan horse. A Trojan horse is a computer program that conceals a harmful code. Relating to the well know tale of the Trojan horse, it allows you into a system, and then leaves an outlet that allows you to get back into the system. In essence, it is software that appears to perform one action while actually performing another (Gohring, 2009, p. 6). A Trojan horse is a program that appears harmless but hides malicious functions. The most common Trojan horse of today’s day and age is NetBus, which was used for illegally breaking into computer systems and, in particular, used to plant child pornography on computers of people of integrity. Viruses are another form of cyber attack. Viruses are programs that â€Å"infect computer files, usually executable programs, by inserting a copy of itself into the file. These copies are usually executed when the infected file is loaded into memory, allowing the virus to affect other files. A virus requires human involvement to spread† (Kuehl, 2012). Virus writers write programs that infect the systems of certain users, but needs direct involvement by the creator or another human source to spread the virus. Very similar to a virus is a worm. The worm works just like a virus, implemented into a system by a creator. The difference between a worm and a virus is the fact that a worm doesn’t need the hands-on human involvement. Back in 2003, SQL Slammer worm spread throughout the cyber world. This was a worm that exploited a buffer overflow vulnerability of Microsoft’s SQL Server. Six months prior to the launch of the worm, the vulnerability was taken notice of and a patch was developed to strengthen the vulnerability. The worm worked by generating random IP addresses, and if belonged to an SQL Server that was not covered by the patch, it was infected and immediately began sending out more copies of the worm to more random IP addresses (Leyden, 2003). There was no human involvement after the worm was created initiated by the creator. It spread itself to random IP addresses, which categorizes it as a worm. Phishing is a form of deception used in cyberspace. Phishing attempts to trick users into giving out their personal data. The techniques used in phishing attempts are emails and websites that are designed to look like legitimate agency websites asking for an individual’s bank and financial account information and passwords (Kuehl, 2012). This method is not used so much by cyberterrorists, but the possibility is there. A more serious cyber attack comes in the form of a Denial of Service (DoS) attack. DoS attacks deny system access to users by overwhelming the target source with messages and blocking legitimate traffic (Kuehl, 2012). It causes a system overload, and can block the ability to exchange data between systems using the Internet. DoS attacks usually target banks, and earlier this year in September, several major banks were attacked using DoS. The websites of Bank of America, JPMorgan Chase, Wells Fargo, U. S. Bank, and PNC Bank all were victims of a DoS attack (Goldman, 2012). The websites were overloaded with traffic directed at them causing them to crash. Most of the time while the cyberterrorists use these attacks to steal information from bank customers, but in this case the motivation was simply to temporarily take down the banks’ public-facing websites, putting them under extreme heat from the public and potentially tarnishing their reputations. There are three levels of cyber capability that need to be taken into thought when considering types of cyberterrorism attacks. The first is simple-unstructured capability. This allows a cyberterrorist to conduct basic hacks against individual systems using tools created by someone else. The organization possesses little target analysis, command and control, or learning capability (Denning, 2000). This level is sometimes not considered to be cyberterrorism, because of the simplicity of the attack. There is slight to no attention focused on the target, which does not reveal any sort of motivation. Referring back to the definition of cyberterrorism, it has to stem from a motivational source to be considered cyberterrorism (Gross, 2003). The simple-unstructured capable individuals are basically the ones who hack into systems just to see what kind of damage they can cause. The second level of capability is the advance-structured level. This is the competence to conduct more sophisticated attacks against multiple systems or networks and possibly, to modify or create basic hacking tools. The organization possesses a straightforward and uncomplicated target analysis, command control, and learning capability (Denning, 2000). These organizations have motivations, but they are not strong enough to cause serious damage to the identified target. The last capability is the complex-coordinated capability. This is the ability for coordinated attacks capable of causing mass-disruption against integrated, heterogeneous defenses. They have the capacity to create sophisticated hacking tools. There is a highly capable target analysis, command control, and organization learning capability (Denning, 2000). Organizations with this type of capability are highly sophisticated with dangerous motivations. These dangerous organizations are the ones that can cause millions of dollars of damage, and also tons of negative publicity, two of the main objectives of cyberterrorist. There are cases when terrorists actually run other forms of terrorisms, such as bombings, with the use of cyberspace. The anonymity and global reach of the Internet has helped facilitate terrorism (Cole Glasser, 2009). â€Å"They put up websites to spread their messages and recruit supporters, and they use the Internet to communicate and coordinate action. However, there are few indications that they are pursuing in cyberterrorism, either alone or in conjunction with acts of violence† (Denning, 2000). There is an example of this from the late 90’s. In February 1998, Clark Staten, executive director of the Emergency Response and Research Institute in Chicago, testified before the Senate Judiciary Committee Subcommittee that it was believed that â€Å"members of some Islamic extremist organizations have been trying to develop a network of hackers to support their computer activities in offensive information warfare attacks in the future† (Denning, Cyberterrorism, 2000). It is the perfect way to recruit, because of the anonymity that is granted to the individual. â€Å"The Internet is the ideal medium for terrorism today: anonymous but pervasive† (Cole Glasser, 2009, p. 95).

Software As A Service Information Technology Essay

Software As A Service Information Technology Essay SaaS is nothing but a high end software model that enhances the interaction of companies with their clients or consumers. The most common instances of SaaS are to track the shipment online or online billing. The advantage of implementing SaaS is that there is no cost incurred upon the consumers/ clients. The software is developed and ported on the internet and is accessible 247 throughout the world. This document covers the information regarding traditional Client-Server model and SaaS. Also advantages and disadvantages of SaaS are discussed in this paper. Document Overview: This document gives an overview of the SaaS, basic architecture how it is using in the real world, and describes the advantages and disadvantages of SaaS. What is SaaS: SaaS is a software application which is ready to use where user can purchase or rent the software on a monthly or yearly basis, and user nothing to worry about application software or any other installation process. Client Server Vs SaaS: Traditionally, most of the software applications have been developed using client-server model. In a client-server model, we can find many hidden costs for supporting and deploying a client server system, together with expensive hardware to install and maintain. In most of the scenarios, the initial software license worth of a client server system is only one third of the total worth of the system. Client Server Model The significance of SaaS is that is a technology platform and its becoming increasingly recognized as a more efficient way to deploy software application. SaaS model is a technique of providing the same software to dissimilar customers through a network, over the Internet. In other way, we can say that the software is not installed on the customers personal computers. SaaS model delineates a vendor is whole responsible for the creation, maintenance, enhancements and all software and hardware related updates. Customers are only responsible for initial purchase of the product or subscription to access it. This subscription includes a separate license for each individual person that will make use the software. The Saas model can add cost savings and efficiency for the both the customer and product vendor. Customers save money and time since they do not have to install drivers and maintain software programs or any other hardware related system upgrade. We get softwares from different customers through network, commonly Internet. Software is not presented in client side, it is provided by a vendor. Vendor have to be uploaded the software in the server. If anything needs to update, preparing to upload new software and maintenance of the application means software vendor has to do this. Once customer purchased the software, he gets the licensed key, it is unique and applicable for one time and no one can share the information. SaaS MODEL SaaS and SOA: SaaS also uses Service Oriented Architecture to communicate between subsystems in the Enterprise Applications. Each application subsystem can act as service to interact with other subsystems via public brokers. These services also act as service requesters. Enterprise application some time requires a web services to verify the data with some other third party agencies. In order to interact with some other application, web service call will be routed through SOA. SaaS Applications: In our real life we are currently using many SaaS applications. Those are free to use but more useful in our real world. Free SaaS Applications: Gmail Google Calendar MapQuest Google Maps. Wikipedia All these above applications have simple interfaces and powerful enough to do everything we want to do. Any types of enhancements for any SaaS application vendor do it in a single shot then everyone (customers) can use those changes on their machines without doing any operations. Profit Organizations Using SaaS Applications: FedEx Chase Air Canada Hertz Google Finance All profit organization using SaaS applications are fully tested while they going for any new application related enhancements or any application related fixes. Benefits of SaaS: Lower Costs: Most SaaS solutions are offered at a lower subscription cost (Monthly/Quarterly/Yearly) with no up-front fees. By using Saas software consumers can save a lot of money. All they have to do is pay a subscription fee for the duration of time they will be using an application for and vendors bear all the security and infrastructure costs. This is a very cost effective solution for users who may only use a software application on rare occasions. Data storage requirements: Some application can occupy a lot of hard drive space at end users systems. By using SaaS software consumers can save a lot of hot drive space because data is stored on the vendors database. Also users dont have to worry about constantly backing up the data as this is handled by SaaS vendors. SaaS vendor profits: SaaS allows software vendors to receive a continuous stream of income in the form of subscriptions. Speed of deployment: Potentially very fast as the application is already up and running on the vendors server so you just have to get your data onto the system. Simpler Solution: The less software and hardware components installed on-premise, the simpler faster the deployment becomes. The time to value is much faster compared to on-premise Alternatives usually measured in minutes. Lower Risk: In a SaaS model the customer can unsubscribe or cancel the subscription, and with no databases and application servers to install, this means lower overall risk to IT and the business. Enhance Scalability:   In SaaS Model expansion of business and contract is easily accommodated by providing the flexibility to expand their operations without having to wait for their Information Technology infrastructure to grasp up. This allows organizations to simply add new applications when they needed. This type of flexibility in other business model is not possible.   Improved Data Security: The SaaS provider has many resources to provide systematic and widespread data security options and guard the computer centers from casual access. Access Anywhere: Users can access their data by using the SaaS application from anywhere as long as they have the internet connection. This will enhance the user experience in making the work done in a faster way. Automatic Upgrades: The version of software available when you log into your SaaS account is latest because there is only one version offered. If there is an error found in the software the SaaS provider can quickly make the changes. Not Platform Specific: The software is platform independent and can be used from any operating system as long as you have an internet connection to use the application. It will enable you to use a wide variety of platforms. End User Advantages: End user or Customer no needs to main the Software, deployments in the server and updating. If new versions are release user nothing to bother about any type of operations. Vendor is responsible to upgrade the versions. But user needs to update those versions. Risks Disadvantages: More costly in the long run: Flouting point usually occurs around two to three years Less manage over the application: Customization and integration of application is more limited for end users. Vendor feasibility becomes even greater unease: Since users data is restricted by the vendor. Security issues: Since the data is stored on the servers of the SaaS application provider there might be a security issue of intruders hacking the personal information while the data is transferred over the network. To prevent this, the SaaS application providers need to apply necessary security patches. It depends on the vendor for providing good security. Limited applications: Generally SaaS vendors offer the applications which are more popular and the application user wants to use may not be he is from that group. So the only way to user use the application is to buy it and install it in his computer. Summary: In this paper we discussed about Software as a Service (SaaS) how it works in a real time and why SaaS replaced by traditional Client Server Model. Also we discussed about various types of applications that are using SaaS. At the end we discussed about advantages, Risks and disadvantages by using SaaS.
