Essay on “Introduction to computer”

Essay on â€Å"Introduction to computer† Question 1 There is no doubt that the emergence of new technologies coupled with developments in the mobile platforms have led to an increased number of Smartphones in the market. This has led to increased innovative capacities from application developers despite the difficulties in making choices concerning the best software platforms (Endre, 2009). Google Android, Nokia Symbian OS, Samsung Bada, Apple iOS, Blackberry OS, and Microsoft Mobile OS are some of the leading mobile operating systems available to developers. However, Apple iOS and Google Android are the two leading but competing mobile operating systems in the market. The aspect of superiority between the two mobile platforms is a subject of debate among many a developer. There is no doubt that each of the two has its own advantage and disadvantage when compared to the other. Advantages of Android OS over iOS First, the Android OS uses the Java programming language and due to its popularity, many software developers find it the most preferable language. When the Android OS is compared to the Apple iOSthat uses the Objective-C language, it becomes more superior because not only programmers are proficient with other programming languages. Second, the Android OS is an open source software that allows for the development of applications using third-party tools. Apple iOS does not give liberty to third-party tools to be used in the development of applications because it has restrictive developer guidelines. Such developer guidelines ensures that developers are limited to the fixed set of tools specified by Apple thereby denying them the ability to play around with increased functionality features of their applications. Such restrictions destroy the creative abilities of application developers. Third, the Android OS is versatile in terms of enabling multitasking functionalities when performing multiple purposes. Users can perform several functionalities such as listening to the radio while writing text messages. In contrast, the Apple iOS allows for one functionality at a time. Fourth, the Android OS offers an ideal environment for testing applications because it offers an indexed set of tools that can be used by developers to test their applications before publishing it in the android market. The Xcode testing tool in the Apple iOS cannot match the specifications of this tool. Fifth, the Android OS requires low system requirements and as such, it can be installed on low productivity platforms without necessarily having to install drivers. Lastly, the Android software supports a variety of Social Integration and Google functionalities and apps. Disadvantages of Android OS over iOS First, the multitasking abilities makes users to develop complex applications that consumes a lot of time and resources master thereby increasing challenges to users and developers. On the other hand, developers under the Apple iOS are given a stable platform where specific tools and boundaries have been specified thereby making it easier for developers to proceed with their development processes. Secondly, applications running on the Android platform cannot Objective-C-based applications as compared to the devices running on the Apple iOS. Third, the android OS has been known to crash more frequently as compared to the Apple iOS. Fourth, Android OS takes longer than usual to load applications as compared to devices that run on the Apple iOS. Finally yet important, by virtue of it being an open source application, a likely of increased application attacks and threats thereby placing the devices at risk. Everybody is capable of creating applications thereby increasing the availabilit y of applications in the android market. Question 2 There is no doubt that the introduction of the transformable-information construct introduced by Tim Burners-Lee two decades ago has brought immense developments in the World Wide Web. The Web is a techno-social system that has enabled human beings to enhance their communication, cognition, and cooperation over technological networks (Kane, and Hegarty, 2007). The aspects of the World Wide Web are defined and described based on technical specifications and non-proprietary standards. Most of these standards involve universally accepted practices that define the criteria for developing websites (Aghaei, Mohammad, and Farsani, 2012). Web standards affect website development and administrations such as the accessibility, usability, and interoperability of web pages. Several technologies have introduced since the inception of the World Wide Web and such standards include Web 1.0 (web of cognition), web 2.0 (web of communication), web 3.0 (web of co-operation), and web 4.0 is a web of integration(Aghaei, Mohammad, and Farsani, 2012). Websites that adhere to web standards enables developers to understand languages used by other developers during coding. The W3C World Wide Web formed in 1994 is charged with the responsibility of creating and maintaining web standards by developing specifications, tools, software, and guidelines to guide the development of websites to reach their full potentials. Web 1.0 Refers to the first generation of the web characterized by cognition started as an avenue for enabling individuals and businesses to broadcast information to the people. It only allowed the process of searching information without giving enough interactions (read-only). Web 2.0 Commonly referred to as the read-and write technological platform, the web 2.0 standards enables users to collect and manage high volumes of individuals having similar interests relating to social interactions (Cormode, and Krishnamurthy, 2008). Dale Dougherty defined the web 2.0 technology in 2004 by presenting it as a business revolution in the computer industry and that the web 2.0 was aimed at building applications that harness network effects that will attract many users. With writing and reading capabilities, the web 2.0 technology enabled the web to be bi-directional such that users had increased controls as compared to the web 1.0 platform (Aghaei, Mohammad, and Farsani, 2012). The major characteristics of the web 2.0 platform include interoperability, information sharing capabilities, information sharing, and collaborations among users on the World Wide Web (Fifarek, 2007). The main services and technologies that can be used alongside the web 2.0 technology include Wikis, blogs, Mashups, Really Simple Syndication (RSS), and tag clouds among others. Technologies used in the development of applications for the web 2.0 platform include XML (AJAX), Google Web Toolkit, Flex, and Asynchronous JavaScript (Aghaei, Mohammad, and Farsani, 2012). Web 3.0 This technology comprises of two platforms of social computing and semantic technologies whereby the later technology facilitates human-machines cooperation by organizing large volumes of individuals into an online community. The former technology represents open standards that are applicable over on top of the web.Introduced in 2003 for purposes of defining structural data and linking them in a manner that allows effective automation, discovery, integration, and re-use across different applications.Another important characteristic for the web 3.0 involves the capability of linking, integrating, and analyzing data collected from different sets to create a new information stream (Aghaei, Mohammad, and Farsani, 2012). Question 3 Cloud computing refers to the use of software and hardware programs to deliver computing services over a network. It entrust services with the computation, software, and data of a user. There are several types of cloud computing open to both personal use and business use. They include desktop as service, security as a service, storage as a service, platform as a service, infrastructure as a service, and IT as a service. Cloud computing enables users to store personal files in remote locations; instead of a user storing files on server computers and hard drives, the concept of cloud computing allows the user to store files remotely in â€Å"clouds†(Rochwerger Caceres, 2009). Cloud computing has numerous benefits when used in an organization. In the business or work environment, common examples of cloud computing may include: the use of web based email services, web communication tools, customer relationship management, software as a service, file backup, file synchronization, and file storage. With the advancement of the concept of cloud computing in the business environment, individual firms can have their own clouds with restrictions. This implies that a firm can own its own cloud for file storage and put limitations on who can or cannot have access to the files(Rochwerger Caceres, 2009). One of the major benefits of using cloud computing in the business environment is that it offers flexibility. This is because employees can be able to access the files stored remotely in the organization’s clouds from any location(Rochwerger Caceres, 2009). As long as an employee does not have any restriction accessing company data, he or she can log in from any location whether in or out of office. It only takes internet connection for the employee to log in and access company data(Rochwerger Caceres, 2009). At the same time, access can be granted using any device that can access the internet including mobile phones, tablets, laptops, desktops, and servers. Employees also have the opportunity to work together on documents without necessarily having to be physically present(Rochwerger Caceres, 2009). Documents and files can be edited, reviewed, and viewed simultaneously from different locations. Secondly, cloud computing is easy to set and keep running. For instance, it is very easy for individual employees to set up user accounts in various online platforms that support file storage and sharing(Rochwerger Caceres, 2009). All that is needed in cloud computing is simply an internet connection and a computer device. Cloud computing is also cheap for companies. It is not labor intensive and a company does not need to install very expensive software programs. All the software and hardware programs are already installed remotely and a business only needs to run the resource online. Many of the applications for cloud computing come at no cost(Rochwerger Caceres, 2009). This means that a company does not have to spend money buying external hard disks and server computers but simply utilize the various forms of cloud computing. Another advantage is the fact that cloud computing offers clients with an unlimited protection. It also allows IT to shift focus(Rochwerger Caceres, 2009) . This means that a client or a firm does not have to bother about updating their server computers and other issues relating with computing. The focus is mainly shifted to increasing and improving innovation(Rochwerger Caceres, 2009). Question 4: Case Study 4 (a): computer security It is often said that the weak link in computer security is not the technology itself but the people who consume the technology. Like in the case of Mary, many people find themselves putting down their guard to allow attackers to hack into their accounts. In most cases, this happens when people are distracted from their work or when they are generally tired with work. These situations will make the workers to feel intimidated or simply just make honest mistakes(White, 2009). Attackers would use some socially engineered schemes to get any sensitive information from the people. Just as in the cases of Mary, the attacker used the pretense that he is calling from the consulting firm that is responsible for providing internet and network solution to Mary’s company(Ministry of Communications and Information Technology, 2011). The conversation was structured in such a way that Mary would not figure out that she is being requested to provide some vital information sufficient to hack i nto her account. According to an article on science daily, software and hardware programs can only do so much in providing security to data. However, it is the responsibility of the people such as Mary to ensure that they follow best practices in safeguarding their computers through passwords and authentication(Lerner Lerner, 2000). 4(b): Since passwords have been compromised severally, one can login into a computer system in other ways. Some of these mechanisms are more secure compared to the traditional use of passwords however the mechanisms have still not been made universally available for use. Biometric is one such alternative and it uses authentication based on the unique personal characteristics of an individual. The error rate for biometrics is high without the use of additional hardware to scan biological characteristics such as figure prints(Lerner Lerner, 2000). The other method for authentication into a computer system is the use of non-text passwords. This may include the use of images, graphical illustrations, color, special characters, and digits instead of the conventional text passwords(Lerner Lerner, 2000).

Rachel closed her eyes as the plane rocketed skyward. She wondered where she had gone wrong this morning. She was supposed to be at a desk writing gists. We will write a custom essay sample on Deception Point Page 12 or any similar topic only for you Order Now Now she was straddling a testosterone-fueled torpedo and breathing through an oxygen mask. By the time the Tomcat leveled out at forty-five thousand feet, Rachel was feeling queasy. She willed herself to focus her thoughts elsewhere. Gazing down at the ocean nine miles below, Rachel felt suddenly far from home. Up front, the pilot was talking to someone on the radio. When the conversation ended, the pilot hung up the radio, and immediately banked the Tomcat sharply left. The plane tipped almost to the vertical, and Rachel felt her stomach do a somersault. Finally, the plane leveled out again. Rachel groaned. â€Å"Thanks for the warning, hotshot.† â€Å"I’m sorry, ma’am, but I’ve just been given the classified coordinates of your meeting with the administrator.† â€Å"Let me guess,† Rachel said. â€Å"Due north?† The pilot seemed confused. â€Å"How did you know that!† Rachel sighed. You gotta love these computer-trained pilots. â€Å"It’s nine A.M., sport, and the sun is on our right. We’re flying north.† There was a moment of silence from the cockpit. â€Å"Yes, ma’am, we’ll be traveling north this morning.† â€Å"And how far north are we going?† The pilot checked the coordinates. â€Å"Approximately three thousand miles.† Rachel sat bolt upright. â€Å"What!† She tried to picture a map, unable even to imagine what was that far north. â€Å"That’s a four-hour flight!† â€Å"At our current speed, yes,† the pilot said. â€Å"Hold on, please.† Before Rachel could respond, the man retracted the F-14’s wings into low-drag position. An instant later, Rachel felt herself slammed into her seat yet again as the plane shot forward as though it had been standing still. Within a minute they were cruising at almost 1,500 miles per hour. Rachel was feeling dizzy now. As the sky tore by with blinding speed, she felt an uncontrollable wave of nausea hit her. The President’s voice echoed faintly. I assure you, Rachel, you will not regret assisting me in this matter. Groaning, Rachel reached for her hack sack. Never trust a politician. 13 Although he disliked the menial filth of public taxis, Senator Sedgewick Sexton had learned to endure the occasional demeaning moment along his road to glory. The grungy Mayflower cab that had just deposited him in the lower parking garage of the Purdue Hotel afforded Sexton something his stretch limousine could not-anonymity. He was pleased to find this lower level deserted, only a few dusty cars dotting a forest of cement pillars. As he made his way diagonally across the garage on foot, Sexton glanced at his watch. 11:15 A.M. Perfect. The man with whom Sexton was meeting was always touchy about punctuality. Then again, Sexton reminded himself, considering who the man represented, he could be touchy about any damned thing he wanted. Sexton saw the white Ford Windstar minivan parked in exactly the same spot as it had been for every one of their meetings – in the eastern corner of the garage, behind a row of trash bins. Sexton would have preferred to meet this man in a suite upstairs, but he certainly understood the precautions. This man’s friends had not gotten to where they were by being careless. As Sexton moved toward the van, he felt the familiar edginess that he always experienced before these encounters. Forcing himself to relax his shoulders, he climbed into the passenger’s seat with a cheery wave. The dark-haired gentleman in the driver’s seat did not smile. The man was almost seventy years old, but his leathery complexion exuded a toughness appropriate to his post as figurehead of an army of brazen visionaries and ruthless entrepreneurs. â€Å"Close the door,† the man said, his voice callous. Sexton obeyed, tolerating the man’s gruffness graciously. After all, this man represented men who controlled enormous sums of money, much of which had been pooled recently to poise Sedgewick Sexton on the threshold of the most powerful office in the world. These meetings, Sexton had come to understand, were less strategy sessions than they were monthly reminders of just how beholden the senator had become to his benefactors. These men were expecting a serious return on their investment. The â€Å"return,† Sexton had to admit, was a shockingly bold demand; and yet, almost more incredibly, it was something that would be within Sexton’s sphere of influence once he took the Oval Office. â€Å"I assume,† Sexton said, having learned how this man liked to get down to business, â€Å"that another installment has been made?† â€Å"It has. And as usual, you are to use these funds solely for your campaign. We have been pleased to see the polls shifting consistently in your favor, and it appears your campaign managers have been spending our money effectively.† â€Å"We’re gaining fast.† â€Å"As I mentioned to you on the phone,† the old man said, â€Å"I have persuaded six more to meet with you tonight.† â€Å"Excellent.† Sexton had blocked off the time already. The old man handed Sexton a folder. â€Å"Here is their information. Study it. They want to know you understand their concerns specifically. They want to know you are sympathetic. I suggest you meet them at your residence.† â€Å"My home? But I usually meet-â€Å" â€Å"Senator, these six men run companies that possess resources well in excess of the others you have met. These men are the big fish, and they are wary. They have more to gain and therefore more to lose. I’ve worked hard to persuade them to meet with you. They will require special handling. A personal touch.† Sexton gave a quick nod. â€Å"Absolutely. I can arrange a meeting at my home.† â€Å"Of course, they will want total privacy.† â€Å"As will I.† â€Å"Good luck,† the old man said. â€Å"If tonight goes well, it could be your last meeting. These men alone can provide what is needed to push the Sexton campaign over the top.† Sexton liked the sound of that. He gave the old man a confident smile. â€Å"With luck, my friend, come election time, we will all claim victory.† â€Å"Victory?† The old man scowled, leaning toward Sexton with ominous eyes. â€Å"Putting you in the White House is only the first step toward victory, senator. I assume you have not forgotten that.† 14 The White House is one of the smallest presidential mansions in the world, measuring only 170 feet in length, 85 feet in depth, and sitting on a mere 18 acres of landscaped grounds. Architect James Hoban’s plan for a box-like stone structure with a hipped roof, balustrade, and columnar entrance, though clearly unoriginal, was selected from the open design contest by judges who praised it as â€Å"attractive, dignified, and flexible.† President Zach Herney, even after three and a half years in the White House, seldom felt at home here among the maze of chandeliers, antiques, and armed Marines. At the moment, however, as he strode toward the West Wing, he felt invigorated and oddly at ease, his feet almost weightless on the plush carpeting. Several members of the White House staff looked up as the President approached. Herney waved and greeted each by name. Their responses, though polite, were subdued and accompanied by forced smiles. â€Å"Good morning, Mr. President.† â€Å"Nice to see you, Mr. President.† â€Å"Good day, sir.† As the President made his way toward his office, he sensed whisperings in his wake. There was an insurrection afoot inside the White House. For the past couple of weeks, the disillusionment at 1600 Pennsylvania Avenue had been growing to a point where Herney was starting to feel like Captain Bligh-commanding a struggling ship whose crew was preparing for mutiny.

Market Related Factors for Apple Watch-myassignmenthelp.com

Question: Discuss about theMarket Related Factors for Apple Watch. Answer: The aim of this report is to do market analysis for the latest product of Apple Inc. of its latest product Apple watch. Apple watch is basically considered as the smart watch which is being introduced by company in the market in 2015. There are some factors of marketing mentioned below. Concentration of target market The market potential of Australia is progressing with current share and the android users in the market are very high. Apple has strong competitors such as Samsung, Motorola, LG and Microsoft that turns into making wearable watches, the demand of the smart watches of Apple will be boon in the market. The target segment for Apple watches must be a young to average age between 16 to 40 years. The main concentration of Apple Company should be on the higher income social groups who are willing to take chances with offered options that is the innovator of the segment (Hsiao and Hsiao, 2017). Figure 1: Apple watch Source: (Khan, Alam and Alam, 2015). Timing of marketing entry Apple is the leading inventor of the new technologies. The apple smart watches are entered in the market when the demands of new technology are required. The features of Apple watch is innovative software like Apple Pay which competitors do not have. However, various success factors are considered while entering into new market (Van der Panne, van Beers Kleinknecht, 2003). It is a new and refreshing product and it enters into the market when it has realized that it has number of loyalty customers and this industry is anticipated to grow (Riches, Martinez, Maison, Klosterman and Griffin, 2015). Competitive pressure The competitors of Apple Company have the ability to attain the competitive advantages. While entering the new market of smart watches by Apple, it has to face the two major competitors, Samsung and Sony, had launched smart watches in the market already that had been presentable in the market for more than 1 year. Additionally, Apple did not show their latest technology at the international CES, Las Vegas while other competitors did. The factor of bargaining power of suppliers has low ability in the context of Apple watches due to their loyalty to Apple. Technological capability is able to perform any relevant function related to technical and it can reduce the pressure of competitive (Berkhout, Hartmann Trott, 2010). Marketing Marketing is an integral part for the Apple company to increase the more sell of the Apple watches. It is required for the company to do external environmental analysis, consumer market analysis and marketing mix. These all procedures would be helped out to determine the specific factors for bringing the growth of the sales. The marketing strategy of apply is very clear and crispy in their message. The competition with Apple on a company level is very low. The Apple watch is unique and due to its high demand and great reputation in the market, its marketing strategy is very attractive. Apple Inc. is able to use its innovative model in effective manner that is why its products produce in the market with latest technology (Berkhout Rietdijk, 2010). The price, product, promotional and place strategy of Apple is effectual. The selling strategy of Apple is efficient when a customer enters the apple store, they are treated and assisted by an employee, who provides the services one on one to make a sale.
