The Story of an Hour Experiencing Grief Differently - Free Essay Example

The Yellow Wallpaper and The Story of an Hour: Experiencing Grief Differently Throughout The Yellow Wallpaper, written by Charlotte Perkins Gillman, the protagonist is described as a woman of the 1800rs facing oppression by male dominance. In comparison, the protagonist from Kate Chopinrs, The Story of an Hour, experiences the same oppression. Both protagonists are dealing with some type of loss over the course of their short story, but in contrast the effectiveness of their loss differs on opposite ends of the spectrum. Ultimately both protagonists are portrayed as women who experience loss and oppression, but how the difference in loss affects each individual varies from joy to sadness. During this period of time, women were granted few rights. Overall the female gender was expected to reproduce and take care of their husbands. As Kate Chopin writes, But she saw beyond that bitter moment a long procession of years to come that would belong to her absolutely. And she opened and spread her arms out to them in welcome (94), along with that, Gillman states, He said I was his darling and his comfort and all he had, and that I must take care of myself for his sake (85). The death of Chopinrs narratorrs husband passing away brought her freedom and self-discovery. Granted the will to no longer serve to her husbandrs needs allows her to spend more time on herself. The pure joy felt by the narrator exemplifies how women were held accountable of taking care of everything else besides themselves. In comparison, Gillmanrs narrator feels pressured to get better not for herself, but because her husband relies heavily on her nurturing. Along with these quotes, one of the more talked about right women were not granted in relevance to The Yellow Wallpaper included the ability to read and write. Jane, the narrator in this specific short story, mentions her writing in secret. For instance, I did write for a while in spite of them; but it does exhaust me a good deal†having to be so sly about it, or else meet with heavy opposition (80), along with And I know John would think it absurd. But I must say what I feel and think in some way†it is such a relief! (85). These statements provided give examples to the claim that women were not granted the right to think for themselves or express how they feel. Thus, another example of oppression. All statements provided support the claim both women were facing oppression by the primary men in their lives. Another comparison that can double as a contrast between these two women was their experience of loss. The narrator from The Yellow Wallpaper lost herself. Over the course of the story, Jane becomes so fixated on the wallpaper and her illness that she loses her sense of self-identity. One example from the text includes, Ive got out at last, said I, in spite of you and Jane. And Ive pulled off most of the paper, so you cant put me back (92). This statement was from Jane directly, referring to herself in third person as if she was a completely different entity. She continues to go on referring to herself that way at throughout the ending of the story. At this point, Jane has lost her sanity and believes to be the women she claimed seeing behind the wallpaper. On the other hand, the Chopinrs narrator experienced a physical loss; the loss of her husband. The author makes is known the husband has passed away early in the story. Even though her husbandrs passing left her joyful, she did me ntion briefly she cared for him when the narrator said, She knew that she would weep again when she saw the kind, tender hands folded in death (94). Although their losses were different, in a sense they have both lost something dear to them. It is known that there are different ways to cope with losses and everyone grieves differently, but these two women could not have reacted anymore opposite. Gillmanrs narrator reacted in complete sorrow and isolation. As Jane is gradually losing herself more over the course of the story, her body is deteriorating along with her mind. For example, written in the text, I dont weigh a bit more, said I, nor as much; and my appetite may be better in the evening when you are here but it is worse in the morning when you are away (86). As the text exemplifies Jane can not eat, nor gain weight. In fact, she is losing weight from this illness. Both symptoms are clear indicators that she is getting worse. On the other hand, Chopinrs protagonist was filled with great joy upon the news of her husbandrs passing. Multiple times after her findings, the protagonist repeats the word free, feeling freedom from constantly serving a man. In the text Chopin writes, But she saw beyond that bitter moment a long procession of years to come that would belong to her absolutely. And she opened and spread her arms out to them in welcome (94). The feeling of no longer having to serve to her husband has allowed the women to begin imagining self-discovery and living for only herself; pure joy and happiness. Ultimately it can be exemplified these short stories were written in comparison and contrast when analyzing the two. As women during a period time before the Womenrs Rights movement, life was difficult and unfair; portraying men as the dominant gender. Charlotte Perkins Gillmanrs narrator was forced to hide her thoughts by writing in secret, along with struggling through sickness that was dismissed by her husband and not taken seriously. Kate Chopinrs protagonist was held captive by societal norms, having to serve her husband. Overall both of these women were suffering through oppression from the primary men in their lives and dealt with loss, but the way they handled their loss differed drastically.

A Computer Virus - Free Essay Example

Sample details Pages: 9 Words: 2847 Downloads: 1 Date added: 2017/09/25 Category Advertising Essay Type Argumentative essay Tags: Computer Essay Did you like this example? A computer virus is a computer program that can copy itself[1] and infect a computer. The term virus is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer. [2][3] The term computer virus is sometimes used as a catch-all phrase to include all types of malware, adware, and spyware programs that do not have the reproductive ability. Malware includes computer viruses, worms, trojans, most rootkits, spyware, dishonest adware, crimeware, and o ther malicious and unwanted software, including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a program that appears harmless but has a hidden agenda. Worms and Trojans, like viruses, may cause harm to either a computer systems hosted data, functional performance, or networking throughput, when they are executed. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or go unnoticed. Infection strategies In order to replicate itself, a virus must be permitted to execute code and write to memory. For this reason, many viruses attach themselves to executable files that may be part of legitimate programs. If a user attempts to launch an infected program, the virus code may be executed simultaneously. Viruses can be divided into two types based on their behavior when they are executed. Nonresident viruses immediately search for other hosts that can be infected, infect those targets, and finally transfer control to the application program they infected. Resident viruses do not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution and transfers control to the host program. The virus stays active in the background and infects new hosts when those files are accessed by other programs or the operating system itself. [edit] Nonresident viruses Nonresident viruses can be thought of as consisting of a finder module and a replication module. The finder module is responsible for finding new files to infect. For each new executable file the finder module encounters, it calls the replication module to infect that file. [edit] Resident viruses Resident viruses contain a replication module that is similar to the one that is employed by nonresident v iruses. This module, however, is not called by a finder module. The virus loads the replication module into memory when it is executed instead and ensures that this module is executed each time the operating system is called to perform a certain operation. The replication module can be called, for example, each time the operating system executes a file. In this case the virus infects every suitable program that is executed on the computer. Resident viruses are sometimes subdivided into a category of fast infectors and a category of slow infectors. Fast infectors are designed to infect as many files as possible. A fast infector, for instance, can infect every potential host file that is accessed. This poses a special problem when using anti-virus software, since a virus scanner will access every potential host file on a computer when it performs a system-wide scan. If the virus scanner fails to notice that such a virus is present in memory the virus can piggy-back on the virus scanner and in this way infect all files that are scanned. Fast infectors rely on their fast infection rate to spread. The disadvantage of this method is that infecting many files may make detection more likely, because the virus may slow down a computer or perform many suspicious actions that can be noticed by anti-virus software. Slow infectors, on the other hand, are designed to infect hosts infrequently. Some slow infectors, for instance, only infect files when they are copied. Slow infectors are designed to avoid detection by limiting their actions: they are less likely to slow down a computer noticeably and will, at most, infrequently trigger anti-virus software that detects suspicious behavior by programs. The slow infector approach, however, does not seem very successful. Stealth Some viruses try to trick antivirus software by intercepting its requests to the operating system. A virus can hide itself by intercepting the antivirus software’s request to read the f ile and passing the request to the virus, instead of the OS. The virus can then return an uninfected version of the file to the antivirus software, so that it seems that the file is clean. Modern antivirus software employs various techniques to counter stealth mechanisms of viruses. The only completely reliable method to avoid stealth is to boot from a medium that is known to be clean Spyware is a type of malware that is installed on computers and collects little bits information at a time about users without their knowledge. The presence of spyware is typically hidden from the user, and can be difficult to detect. Typically, spyware is secretly installed on the users personal computer. Sometimes, however, spywares such as keyloggers are installed by the owner of a shared, corporate, or public computer on purpose in order to secretly monitor other users. While the term spyware suggests that software that secretly monitors the users computing, the functions of spyware extend we ll beyond simple monitoring. Spyware programs can collect various types of personal information, such as Internet surfing habits and sites that have been visited, but can also interfere with user control of the computer in other ways, such as installing additional software and redirecting Web browser activity. Spyware is known to change computer settings, resulting in slow connection speeds, different home pages, and/or loss of Internet or functionality of other programs. In an attempt to increase the understanding of spyware, a more formal classification of its included software types is captured under the term privacy-invasive software. In response to the emergence of spyware, a small industry has sprung up dealing in anti-spyware software. Running anti-spyware software has become a widely recognized element of computer security practices for computers, especially those running Microsoft Windows. A number of jurisdictions have passed anti-spyware laws, which usually target any software that is surreptitiously installed to control a users computer. The US Federal Trade Commission has placed on the Internet a page of advice to consumers about how to lower the risk of spyware infection, including a list of dos and donts. Routes of infection [pic] [pic] Malicious websites attempt to install spyware on readers computers. Spyware does not directly spread in the manner of a computer virus or worm: generally, an infected system does not attempt to transmit the infection to other computers. Instead, spyware gets on a system through deception of the user or through exploitation of software vulnerabilities. Most spyware is installed without users knowledge. Since they tend not to install software if they know that it will disrupt their working environment and compromise their privacy, spyware deceives users, either by piggybacking on a piece of desirable software such as Kazaa, or by tricking them into installing it (the Trojan horse method). Some rogue spywa re programs masquerade as security software. The distributor of spyware usually presents the program as a useful utility—for instance as a Web accelerator or as a helpful software agent. Users download and install the software without immediately suspecting that it could cause harm. For example, Bonzi Buddy, a program bundled with spyware[9] and targeted at children, claims that: He will explore the Internet with you as your very own friend and sidekick! He can talk, walk, joke, browse, search, e-mail, and download like no other friend youve ever had! He even has the ability to compare prices on the products you love and help you save money! Best of all, hes FREE! [10] Spyware can also come bundled with other software. The user downloads a program and installs it, and the installer additionally installs the spyware. Although the desirable software itself may do no harm, the bundled spyware does. In some cases, spyware authors have paid shareware authors to bundle spywar e with their software. In other cases, spyware authors have repackaged desirable freeware with installers that slipstream spyware. Some spyware authors infect a system through security holes in the Web browser or in other software. When the user navigates to a Web page controlled by the spyware author, the page contains code which attacks the browser and forces the download and installation of spyware. The spyware author would also have some extensive knowledge of commercially-available anti-virus and firewall software. This has become known as a drive-by download, which leaves the user a hapless bystander to the attack. Common browser exploits target security vulnerabilities in Internet Explorer and in the Sun Microsystems Java runtime. The installation of spyware frequently involves Internet Explorer. Its popularity and history of security issues have made it the most frequent target. Its deep integration with the Windows environment and scriptability make it an obvious poin t of attack into Windows. Internet Explorer also serves as a point of attachment for spyware in the form of Browser Helper Objects, which modify the browsers behavior to add toolbars or to redirect traffic. In a few cases, a worm or virus has delivered a spyware payload. Some attackers used the Spybot worm to install spyware that put pornographic pop-ups on the infected systems screen. [11] By directing traffic to ads set up to channel funds to the spyware authors, they profit personally. Examples of spyware †¢ CoolWebSearch, a group of programs, takes advantage of Internet Explorer vulnerabilities. The package directs traffic to advertisements on Web sites including coolwebsearch. com. It displays pop-up ads, rewrites search engine results, and alters the infected computers hosts file to direct DNS lookups to these sites. [30] †¢ Internet Optimizer, also known as DyFuCa, redirects Internet Explorer error pages to advertising. When users follow a broken link or enter an erroneous URL, they see a page of advertisements. However, because password-protected Web sites (HTTP Basic authentication) use the same mechanism as HTTP errors, Internet Optimizer makes it impossible for the user to access password-protected sites. [31] †¢ HuntBar, aka WinTools or Adware. Websearch, was installed by an ActiveX drive-by download at affiliate Web sites, or by advertisements displayed by other spyware programs—an example of how spyware can install more spyware. These programs add toolbars to IE, track aggregate browsing behavior, redirect affiliate references, and display advertisements Computer worm A computer worm is a self-replicating computer program. It uses a network to send copies of itself to other nodes (computers on the network) and it may do so without any user intervention. This is due to the poor security the computers infected have. Unlike a virus, it does not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted compute Worms with good intent Beginning with the very first research into worms at Xerox PARC, there have been attempts to create useful worms. The Nachi family of worms, for example, tried to download and install patches from Microsofts website to fix vulnerabilities in the host system – by exploiting those same vulnerabilities. In practice, although this may have made these systems more secure, it generated considerable network traffic, rebooted the machine in the course of patching it, and did its work without the consent of the computers owner or user. Some worms, such as XSS worms, have been written for research to determine the factors of how worms spread, such as social activity and change in user behavior, while other worms are little more than a prank, such as one that sends the popular image macro of an owl with the phrase O RLY? to a print queue in the infected computer. Most security experts regard all worms as malware, whatever their payload or their writers intentions. [edit] Protecting against dangerous computer worms Worms spread by exploiting vulnerabilities in operating systems. All vendors upply regular security updates[6] (see Patch Tuesday), and if these are installed to a machine then the majority of worms are unable to spread to it. If a vendor acknowledges a vulnerability, but has yet to release a security update to patch it, a zero day exploit is possible. However, these are relatively rare. Users need to be wary of opening unexpected email,[7] and should not run attached files or programs, or visit web sites that are linked to such emails. However, as with the ILOVEYOU worm, and with the increased growth and efficiency of phishing attacks, it remains possible to trick the end-user into running a malicious code. Anti-virus and anti-spyware software are helpful, but must be kept up-to-date with new pattern files at least every few days. The use of a firewall is also recommended. In the April-June, 2008, issue of IEEE Transactions on Dependable and Secure Computing, computer scientists describe a potential new way to combat internet worms. The researchers discovered how to contain the kind of worm that scans the Internet randomly, looking for vulnerable hosts to infect. They found that the key is for software to monitor the number of scans that machines on a network sends out. When a machine starts sending out too many scans, it is a sign that it has been infected, allowing administrators to take it off line and check it for viruses A Trojan horse (sometimes shortened to trojan[n 1]), is non-self-replicating malware that appears to perform a desirable function for the user but instead facilitates unauthorized access to the users computer system. The term is derived from the Trojan Horse story in Greek mythology. Purpose and operation Trojan horses are designed to a llow a hacker remote access to a target computer system. Once a Trojan horse has been installed on a target computer system, it is possible for a hacker to access it remotely and perform various operations. The operations that a hacker can perform are limited by user privileges on the target computer system and the design of the Trojan horse. Operations that could be performed by a hacker on a target computer system include: †¢ Use of the machine as part of a botnet (i. e. to perform spamming or to perform Distributed Denial-of-service (DDoS) attacks) †¢ Data theft (e. g. passwords, credit card information, etc. ) †¢ Installation of software (including other malware) Downloading or uploading of files †¢ Modification or deletion of files †¢ Keystroke logging †¢ Viewing the users screen †¢ Wasting computer storage space Trojan horses require interaction with a hacker to fulfill their purpose, though the hacker need not be the individual responsibl e for distributing the Trojan horse. In fact, it is possible for hackers to scan computers on a network using a port scanner in the hope of finding one with a Trojan horse installed, that the hacker can then use to control the target computer. [1] A trojan differs from a virus in that only a file specifically designed to carry it can do so. edit] Installation and distribution Trojan horses can be installed through the following methods: †¢ Software downloads (i. e. a Trojan horse included as part of a software application downloaded from a file sharing network) †¢ Websites containing executable content (i. e. a Trojan horse in the form of an ActiveX control) †¢ Email attachments †¢ Application exploits (i. e. flaws in a web browser, media player, messaging client, or other software that can be exploited to allow installation of a Trojan horse) Also, there have been reports of compilers that are themselves Trojan horses. citation needed] While compiling code to ex ecutable form, they include code that causes the output executable to become a Trojan horse. [edit] Removal Antivirus software is designed to detect and delete Trojan horses, as well as preventing them from ever being installed. Although it is possible to remove a Trojan horse manually, it requires a full understanding of how that particular Trojan horse operates.

Judas is wearing blue and green clothes and is clutching a small bag, which is recognized by many to be the silver given to him as payment to betray Jesus. The most important part of his representation is that he is in shadow, which somehow reveals that he is responsible for the future death of Christ. Next to Judas are Peter, who is visibly furious, and John who looks like is going to fade away.
