Analysis of Windows Operating System and Microsoft

Analysis of Windows Operating System and Microsoft What is Windows? Windows is a personal computer operating system from Microsoft that, together with some commonly used business applications such as Microsoft PowerPoint, Word and Excel, has become a de facto â€Å"standard† for individual users in most corporations as well as in most homes. It provides a graphical user interface (GUI), virtual memory management, multitasking, and support for many peripheral devices. According to OneStat.com, as of August, 2006, Windows as a whole dominates the personal computer world, running on about 97% of the operating system market share, with XP accounting for about 87% of that. In comparison Mac OS has about 2% and Linux (with all distributions) about .36% The reason why this is so is mainly because Windows is much more user friendly and everything comes pre-packaged so user just have to run the application and follow instructions for it to install. There are many versions of Windows Operating System available namely: Windows 286 W indows 386 Windows 3.0 and 3.11 Windows 95 Windows 98 Windows NT Windows 2000 Windows CE for use in small mobile computers Windows Me Windows XP Windows Vista Windows 7 Among all those versions, Windows XP is the most popular one and it is used by 61.9 percent of Internet users, according to data from Net Applications, followed by Windows 7 which has 14.46 percent of users and Vista -14.34 percent. A Brief Story On Windows Windows mainly concentrated on providing an operating system which was user-friendly, stable and less prone to crashes when they were implementing earlier versions. Now, even though XP is generally referred to being stable and efficient compared to other copies of Windows, it is still critised for being overly susceptible to security risks. Therefore the successor of XP- Vista, released in January of 2007 was designed in such a way so as it provides more security. The transition time between Vista and XP is the longest one between versions of windows. Vulnerabilities Of Windows What is vulnerability? – â€Å"It is a weakness that makes a threat possible. â€Å" These vulnerabilities are used by attackers who exploits them to convey multiple attack, including enticing the users to open harmful and malicious media or to visit website which has a lot of viruses. These can have a lot of consequences. In the worst case, a hacker or attacker can get full access to the computer. Fortunately, windows provide a lot of solution to these vulnerabilities. The user just has to install the appropriate Microsoft patches or they are sometimes installed automatically with the help of Windows Update. Window Update Vulnerabilities can be compared to holes. They are like holes in the system. Windows periodically releases security patches mostly as Window Updates to fix those defects. There exists different level of security known as the â€Å"security level system† in Windows which describes the different levels of security holes: A critical security hole is â€Å"a vulnerability whose exploitation could allow the propagation of an Internet worm without user action.† An important hole is â€Å" A vulnerability whoses exploitation could result in compromise of the confidentiality, integrity, or availability of user’s data, or of the integrity or availability of processing recources.†

Glaciation in Ohio and impacts of glaciation in Ohio Essay

Glaciation in Ohio and impacts of glaciation in Ohio - Essay Example The most important impact of glaciation is the materials that have been left behind by the sheets of ice. These materials includes particles of clay, sand, gravel and rock debris. Most of the materials that had been deposited both above and under the surface of water as a result of glaciation has resulted in formation of geographical features called eskers and kames (Peacefull, 1996). The numerous kames that are found in Portage and Summit counties are a result of deposition of glaciation materials in-between ice sheets that protruded southwards. Comparatively eskers are rare in Ohio although one may encounter eskers in Portage County. Another major impact of glaciation in Ohio is the formation of the glacial lakes. The deposits of these lakes were primarily constituted of fine clay and silt particles. Changes in the drainage pattern of Ohio is also a result of glaciation which disrupted the northwest flow of the River Teays and its tributaries which helped in the formation of Lake Tight in southern

Produce a critical interpretation of the geographies represented in a Dissertation

Produce a critical interpretation of the geographies represented in a selected advertisement, set of advertisements, or advertis - Dissertation Example A critical geography of the advertisements reveal that, underneath the moralistic overtones and admittedly positive social messages, there is insidious propaganda and micro-politicking at work designed to advance specific partisan agendas. Having the moral high ground is of unimaginable importance in politics. Being associated with values has been a major success for the Republican party in America: Democrats can win an advantage in the perceptions of being able to handle domestic and economic issues, but the Republicans are associated with a strong moral compass provided overwhelmingly by traditional Christian values. This itself is an immense propaganda success. First of all, as Gallup has pointed out, in fact Republicans and Democrats are often dead-even in public perceptions of their values, and certainly Republican scandals have not helped the party in securing a consistent values victory: The fact that it is a political bromide that Republicans won the values war shows itself h ow good the Republicans have been in terms of presenting a mystique of a values-based party (2006, p. 526-527). â€Å"For example, the persistent claim that President Bush’s re-election was the result of a â€Å"moral values† revolt by Christians has been seriously overblown. After all, Bush actually received more votes (and a higher percentage of votes) from those who said terrorism was the most important issue than he did from those who identified moral values as the key to their electoral behavior† (Wise, 2005). To be clear, then: The commodity these adverts try to sell is values. They try to get voters and Christian viewers to associate themselves with conservative channels, and they are part of a political campaign. Their analysis in terms of critical geography has to be like political advertisements, which are also carefully controlled to be disagreeable to as few people as possible within the selected geography or micro-geography while energizing the base sufficiently. These adverts play well in heartland Republican America, red states away from the coasts. America as a space, both outdoors and indoors, city and country, is represented as a place of uniform and unchanging values; a Christian nation with a strong bedrock of decency. Second, a fact that we will return to, it is simply not the case that evangelicals or people with religious values vote Republican: White evangelicals do. Black evangelicals and devout Latina/o Catholics, as well as Jews and Catholics in general, far more strongly trend Democratic. â€Å"The racial voting gap was especially pronounced among evangelical Christians. This isparticularly important, given the inane pronouncements about how evangelicals were responsible for Bush’s victory. Fact is, only white evangelicals elevate their provincial moral concerns above classical conceptions of self-interest. Black evangelicals — a sizable group to be sure — voted against Bush by margins of a t least four to one, despite often agreeing with conservatives on certain issues like abortion, gay rights or prayer in schools. But white evangelicals and â€Å"born again Christians† voted 78-21 for Bush, a huge increase from the 62 percent average received by the Republican candidate in the two previous Presidential contests† (Wise, 2005). In fact, the race gap is a far bigger gap in terms of predicting votes in American elections than the geographic, gender, and even class gap! Third: Democrats have
