Performance Evaluation of Operating System †Assignmenthelp.com

Question: Discuss about the Performance Evaluation of Operating System. Answer: Introduction This report introduces detailed aspect of Windows Operating System, a product of Microsoft Corporations. An operating system is a program or software of enormous size that controls the functionalities of both the hardware and software on a computing device such as a computer, laptop and such. Some examples of operating system are Microsoft Windows, Linux, iOS, macOS, Chrome OS, Google Android and such. Microsoft Windows is an operating system that is used both in personal and business purposes. It has become the most popular operating system for its simplicity and functional ease from the time Microsoft Corporation has launched MS Dos since 1981. Windows is an operating system for computing devices launched by Microsoft Corporation. The journey of Microsoft Windows begins in the year of 1981 with the launching of MSDOS. The product was nothing but an operating system that is operated using text-based commands. Bill Gates, the founder of Microsoft Corporations, who identified the potential in GUI-based systems, conceived the idea behind the development of Windows [1]. Gates named the project Interface Manager. The idea of Bill Gates was to produce a GUI based system for the common mass that will have cheap cost and easy to handle. The idea was widely accepted and supported by the Microsoft personnel; however, they did not approve the name that has been coined by Gates. After considerable trial and error, the name Windows was finalised. Windows 1.0 was launched in 1985, which was used by single workplaces for consumers and later was modified with extra network support [1]. Windows is an operating system that manages the hardware and software of a computing device such as laptop, tablet, mobile phone, and such. Windows debut was in the form of MSDOS in the year 1981 followed by Windows 1.0 in 1985. Windows has continued its triumphant journey and evolved as it proceeded through years mitigating demands of the users and learning from the errors of its predecessors. The various features of Windows in the recent versions allow a user to perform almost all the daily tasks on the computer [2]. A Windows user can easily access the internet, check email, play games, view and edit images and videos and a lot more tasks. Windows supports a wide range of tools that help a personal user as well as an organisation to perform various kinds of personal and organisational jobs. Windows need not be installed in a computer for it to serve its utility. It can be hosted on a server and can be accessed by a user to avail all the functions of the system. This reduces the pr oblem of maintain the operating system itself and using up the memory of the local computer to store the software [2]. Technical Details of Windows in terms of Networking Microsoft Windows have launched a product that consists of special functions for establishing a local area network (LAN) connection with a computer and other devices. These types of systems are known as network operating systems (NOS). Windows Server and Windows NT are examples of NOS. Most of the latest operating systems have pre-integrated software that helps to simplify the networking process of a computer. Typical Windows Operating System consists of TCP/IP protocol stack and relevant utility programs such as ping [3]. To enable a devices Ethernet interface, necessary device drivers and other relevant software are also included. Earlier versions of Microsoft Windows lacked in supporting computer network facility. Windows 95 and Windows for Workgroups are the first in line Operating Systems launched by Microsoft Windows that had basic networking capability in its system. The company even introduced its Internet Connection Sharing (ICS) function in Windows 98 SE, Windows 7 and so o n. The figure provided below shows the technical details of Windows Server 2016 [3]. Advantages and Disadvantages of Windows in Relation to Client-Server Network The table provided below shows the advantages and disadvantages of Windows in relation to client-server networking: Advantages Disadvantages Server access is possible remotely. New technology integration is less complicated. Secure system. Addition and removal of new resources is easy. All the devices connected to the server are affected if the server crashes. The setup is expensive. More personnel are required for the maintenance of these types of systems. Table 1: Advantages and Disadvantages of Windows in terms of Client-Server Network Improvements made on Windows over years The journey of Windows Operating System begins with the debut of MSDOS that could be operated by using text-based command line parameters. MSDOS helped in basic programming in C language and performing simple tasks like writing and storing text documents [5]. The latest version of Windows, that is, Windows 10 provides the user a wide array of options to perform various tasks like playing games, accessing and surfing the net, viewing and editing image and video files and many more [6]. Windows have evolved considerably in its triumphant journey from being a text-based command line driven system to a system power packed with all the latest facilities to work and stay connected with the rest of the world [7]. The figure provided below gives the complete list of Windows operating System starting from the Interface Manager launched in 1981 to Windows Server 2016 in 2016 [8]. Conclusion The report concludes with the fact that Microsoft Windows is an operating system that helps a lot in establishing network connection with its simple features and network functionalities that can be used easily by any user. Windows provides the opportunity to connect to the internet by either peer-to-peer connection or client server network model. There are many advantages and disadvantages related to both the model however, the best approach is client-server model.

I’d always made myself believe I was invincible, never worrying about the warnings that’d been thrown at me. Each year going by was bringing sixteen closer and closer. Everything about sixteen had been appealing, but what stuck out the most was the jingling of the keys to a car that would soon be mine. Patience at fifteen, with a permit and no way out, is more difficult than anything I’d ever imagined. My parents had laughed when sixteen came and I had my escape. The only problem was I wasn’t really free. They’d thrown out ideas of a job, which could provide me things I’d come to expect to be given to me. At an innocent age of sixteen, a job sounded delightful, offering me a way out. With money I could buy a car and gas. With that money I could buy my freedom.

The one question I’d thought but, the questions I should’ve asked were, â€Å"Could I do this? Could I handle a job and school?† And at the time I believed it would be easy. I’d watched my mom be strong for us, while handling a job, and knew I could handle a job. The balance between my job and school was and still is difficult to keep even. Eight hours of work at school, then four or five hours of work at night, an hour or two of homework, and then finally managing to fall asleep somewhere between eleven and midnight. But what a job has taught me is to see responsibility in a completely different way. I’d always thought responsibility was something you could choose to do, the consequences of not doing them never bothering me. But after working for almost two years, I’ve learned you can choose not to face your responsibilities but you should face them in order to grow.

Higher Learning essays

Higher Learning essays John Singletons Higher Learning was not only an extremely entertaining film, but one that dealt with many real life issues, such as: importance of college education, sexuality, racism, and social equality. Although there are many troubles that are created in this very intense and dramatic movie, there are barely any significant answers. This movie takes place at Columbus University and it focuses on the lives of three freshmen that have just entered the school. Malik (Omar Epps) is an African-American track star who is habitually challenged by sixth year senior Fudge (Ice Cube) and his fair-opinioned political science teacher Mr. Phipps (Lawrence Fishburne). Then there is Kristen (Kristy Swanson), who is a beautiful Orange County girl that is hauled in by a lesbian (Jennifer Connelly) after she is raped by a social contact. And then there is Remy (Michael Rapaport), who is a white male from Idaho whose inability to fit in anywhere leads him to a group of white supremacists. Although there are three separate stories going on throughout the movie, they are consistently linked in the sense of adolescent students attempting to find their right place, but sometimes, just like in real life, going down the wrong and immoral path. Remy adapts this idea of hate against anybody who isnt a white supremacist, especially African-Americans, and it unavoidably leads to violence. Remy grows in the sense that he finds a belonging with a group, even though the group is morally wrong. In the beginning of the movie Remy had a hard time fitting in with anybody. After Kristen is raped, she characterizes the young people of todays modern world by becoming mesmerized with the unique and unfamiliar, which in this case is lesbianism. And Malik, like a majority of young people without a sense of direction, plays the blame game and thinks nothing is his fault, even though he is blatantly not giving his bes...

Spelling Tips The Y to I Rule

Spelling Tips The Y to I Rule Spelling Tips: The Y to I Rule When a word ends in a vowel plus â€Å"-y,† it’s usually straightforward to modify it by adding a letter (or letters); adding â€Å"-ous,† for example, means â€Å"joy† becomes â€Å"joyous.† However, when a word ends in a consonant plus â€Å"y† things get more complicated, which can make spelling challenging. To ensure your written work is error-free, it helps to keep the y to i rule in mind. The Y to I Rule The basic rule is, for any word that ends in a consonant plus â€Å"-y,† change the â€Å"y† to â€Å"i† if adding a suffix or forming a plural. Plurals For plurals, simply change the â€Å"y† to an â€Å"-ies†: Singular Plural Story Stories Candy Candies Hippy Hippies First-Person Singular Past Tense Verbs Forming the first-person singular of a verb ending in a consonant plus â€Å"y† requires changing the â€Å"y† to â€Å"-ies,† while the past tense involves switching â€Å"y† for â€Å"-ied†: Verb First-Person Singular Past Tense Fry Fries Fried Apply Applies Applied Beautify Beautifies Beautified Comparatives Superlatives When an adjective ends in a consonant plus â€Å"-y,† forming a comparative or superlative involves changing the â€Å"y† to â€Å"-ier† and â€Å"-iest† respectively: Adjective Comparative Superlative Tiny Tinier Tiniest Jumpy Jumpier Jumpiest Thirsty Thirstier Thirstiest Forming Adverbs Modifying an adjective to make an adverb involves substituting the â€Å"y† for â€Å"-ily†: Adjective Adverb Happy Happily Lazy Lazily Flimsy Flimsily Exceptions The â€Å"y†-to-â€Å"i† rule doesn’t always work; some variations of â€Å"sly,† for example, can be spelled with either a â€Å"y† or an â€Å"i† (e.g., â€Å"slyest/sliest† and â€Å"slyer/slier†). Moreover, while changing â€Å"y† to â€Å"i† isn’t typically necessary when a word ends with a vowel plus â€Å"-y,† there are exceptions here too (such as modifying â€Å"day† to become â€Å"daily†). As such, although the y to i rule is a good guideline, it’s still important to double-check words if you’re not sure they’re spelled correctly.

Argument about smoking in malls Assignment Example | Topics and Well Written Essays - 750 words

Argument about smoking in malls - Assignment Example The World Health Organization (WHO) estimates that over 47 million people in the United States aged above 18 years smoke, and as a matter of fact, over half of this population will suffer disabilities or die (Berton, 2006). Smoking should be banned in malls, as the consequences suffered from smoking and secondary smoking are far too grave. Effects of secondary smoking to non-smokers in Malls Secondary smoking is a condition in which non-smokers inhale smoke from smokers’ act of smoking in public places. Research shows that over 4000 compounds are contained in second hand smoke from smokers of which 200 are poisonous. This is a dangerous trend as the smokers not only put there health in danger but also jeopardize the health of the individuals in the mall. Should the banning of smoking be implemented in malls, many lives would have been rescued from the impending danger that these secondary smoke pose to the general public that use the mall, including children of all ages that s eek various services from the many amenities that are hosted in a mall (Patrick, 2008). A demerit will however be to the businesses in the malls that sell cigarettes. The banning will probably mean that malls will be a no smoking zone, quickly diminishing the market that would be available for the cigarettes that many business premises carry out in these malls. This will also translate to a lot of losses that the government gets from hefty revenues that governments get from the sale of cigarettes. Probable steps in reducing the population that smokes A large fraction of the population worldwide is known to smoke. It is reported that a third of the entire male population worldwide smokes. A lesser statistic is however documented for female smokers though it is steadily rising. By banning smoking or introducing stringent measures about smoking in malls, a large population is bound to eventually lose the habit. This would be a big step to most countries as the number of diseases that a re related to smoking cases is so alarming. It is also established that smoking kills one out of 10 that die globally. There is no doubt at all that reducing the numbers via such an action would prevent numerous deaths and fatal ailments that smokers usually undergo but won’t just stop due to the addiction suffered (Joelle, 2002). The reduction of smokers will however cause a big blow to the manufacturing industries, the government for its revenue and advertising houses that all make huge profits from activities related to smoking or cigarettes in general. There is also a danger of withdrawal symptoms that will be exhibited by most ex-smokers, a condition that always cause irritability and the reduction of concentration, factors that may really affects ones daily activities. Reduced Influence on underage Children and Teenagers Even though it is recorded that a majority of teenagers get into smoking as a result of peer pressure from fellow peers, a large percentage can be infl uenced into the habit just by public exposure in places like malls and public parks. It becomes worse when they see an influential figure publicly smoking in a mall; something that will make them conclude that the habit is cool. Apart from just the influence, teenagers and children are also prone to health hazards that might be impacted by secondary smoking. Should smoking be banned or limited in malls, many kids are bound to escape forced introduction into

Contemporary Irish Films Essay Example | Topics and Well Written Essays - 3000 words

Contemporary Irish Films - Essay Example This drama implementation on TV has contributed to the widespread and popularity of such true-to-life documentaries appearance in cinema tends to prioritise the creative influence of the film's directors. [Pettitt, 2000] Thus, making their films the tend to deal with the topics of abuse from the past; based on true stories they have their great emotional effect on the viewers, and uncover the real sense of the traditional social political and religious establishments which rules the life of people for a long time. That's why the real historical or fictional characters, or the images of the USA President appear to perceive the reality depicted in the film in a more deeper sense. Drama has also challenged viewers' minds by imagining events that could not be countenanced by factual television. Fictional representations, therefore, have played a major role in the maintenance and reshaping of perceptions about the Troubles and to this extent they have performed a political function. [Pettitt, 2000] The reports stay that the number of screens in Ireland has increased by 68% from 192 screens to 322 screens (during the period of 1991-2001), but the number of cinemas in Ireland has reduced by 15% from 81 cinemas to 69 in the same period. As for the contemporary Irish films, Pettitt who deals with the films after the 1970s, speaks about both the great thread posed by the influence of Hollywood - dubbed 'Californication' by Oliver St. John Gogarty three-quarters of the century ago - and the need for the resources that the American films companies can supply. [Pettitt, 2000] He also points out the fact that Irish cinema, for all its independence, hews fairly closely to the Hollywood formula followed everywhere from West Los Angeles to Bombay. According to Pettitt (2000), drama since the late 1960s has explored some of the deepest fears of those embroiled in conflict, but has not only reflected the political shifts in Northern Ireland. The political, security and legal apparatus of the British establishment has been most effectively critiqued at different junctures in the drama-documentary format. There has been a line of drama that has interrogated the problematic relationship of unionism within Anglo-Irish politics and the increasingly attenuated sense of Ulster loyalism. Fictional representations, therefore, have played a major role in the maintenance and reshaping of perceptions about the Troubles and to this extent they have performed a political function. [Pettitt, 2000] According to Crosson (2003), contemporary Irish film itself reflects the failure of Irish history to excite the imagination of Ireland's youth as effectively as the seductive depictions of America's past as medicated through the Western and gangster films. So that, films made in Ireland today reflect both these genres. The Irish cinema-going experience has come from Hollywood since in independence in 1922. [Rockett, 1991; p.19] The Irish Film Board has attempted to counterpart Ireland's huge dependence on imported film by supporting films made in the country and by Irish people. However, Ireland remains a substantial net importer of images, many of them
