1. What is software maintenance? Software maintenance stands for modifications and updates done to the software after the delivery of software product. There are several different reasons, why software maintenance is required. Software needs to be updated regularly to keep it functional with the new and latest technology. Once software is developed, it does not mean it is the final product or perfect. Software may need to be modified or updated because of errors or new customer wants new features to be added to the software. There are also several other reasons such as market conditions, host modifications and organization changes. (Tutorialspoint 2015) Software maintenance is a process of modifying a software system or component after …show more content…
it is released. This can mean different processes such as correcting faults, improving performance and other attributes or adapting to new environment. (IEEE 1990) After years of studies and surveys many consider the IEEE standard outdated and find this view on software maintenance inaccurate. Software maintenance process should start at the early stages of software development. Maintenances are divided into two different sections, pre-delivery and post-delivery stages. Pre-delivery stage contains processes such as planning for different post-delivery operations, supportability and logistics determination. Post-delivery stage which means after the software is delivered to the customer contains maintenances such as software modifications and training. Software maintenance is not just a process of fixing bugs, it is similar to software development as over the time environment changes and the software needs to evolve. (Petr Marounek 2012/3, 52; Carl Allen). 2. Different types of software maintenances Software maintenances are separated into four different types of maintenances.
Maintenance may be corrective, adaptive, perfective or preventive maintenance, depending on the situation and software. The maintenance may be a routine maintenance to address an error or it could be larger scale maintenance to keep the software up-to date. Operating systems upgrade over time and hardware keeps changing. At the same time software needs to be upgraded to keep it functional. However, sometimes the structure of the software does not allow these maintenances to be done. Different maintenances done to software may also decay the software structure. More and more maintenances are done which may decrease the software structure. At some point this will become too complicated and uneconomic to maintain and it is better to replace the system.

Allen) 2.1 Corrective maintenance and preventative maintenance Corrective maintenance includes modifications and updates to correct or fix bugs and errors which are reported by users of the software or received from user reports. It is simply correcting discovered problems. Preventative maintenance means modifications and updates to the software to prevent problems happening in the future. Some problems may not be crucial at certain time but with preventative maintenance these problems can be detected and fixed before they become effective and serious problems. (Tutorialspoint 2015) 2.2 Perfective maintenance and adaptive maintenance Perfective maintenance means updating and making modifications to improve performance and maintainability.
The goal of perfective maintenance is not to address errors or problems. Instead of solving issues, perfective maintenance focuses on enhancing the software. This can mean adding new features or improving customer user experience. (Tutorialspoint 2015) Adaptive maintenance is about upgrading and modifying a software to keep it up with latest technology and changes in the business environment. Eventually a software becomes outdated if it has not been updated and it is having problems because of new environment requires newer technology. To keep the software up to date it needs an adaptive maintenance to adapt into new changes. (Tutorialspoint 2015; McCormack & Damian Conway
2005) According to studies, software maintenance is more than 50% of the whole cost of software. Different factors affect the software costs which are divided in to two different factors such as real-world factors and software-end factors. Real-life factors can be caused by many different things which may cost more. Older software is outdated and requires more maintenance as they cannot keep up with the latest software and technology. As new technology is released the cost of keeping older software becomes costly. People who perform the maintenance may be inexperienced and might use questionable methods which could make the maintenance process harder in the future and result in costing more. Some software-end factors can affect the price such as structure of the software. This could make the maintenance require more work and become more costly. Different software may be programmed with different programming languages which could cause problems when certain programming language does not offer the needed possibilities. (Tutorialspoint 2015)
Application Virtualization: Application virtualization conveys an application that is facilitated on a solitary machine to a substantial number of clients. The application can be arranged in the cloud on high-review virtual machines be that as it may, in light of the fact that a substantial number of clients get to it, its expenses are some common by those clients.

Dodger was being sent off to Australia, he got caught for stealing. Fagin freaked out, he was thinking that Dodger would rat them out and it would be over for them. Soon after Fagin got the news, Monks showed up… He wanted Charley out of the room. He was about to tell him what Nancy did. Bill flipped out, thinking that she turned against him. He went to go find Nancy. On the way to find her, everyone got out of his way; nobody wanted his attention. He asked everyone if they have seen her and they all said “no.” Then, Bill found Nancy… Seconds later there was a loud scream. Everyone ran to see what happened and saw Nancy’s lifeless body with Bill running away. People chased after Bill, he went to Fagin’s place asking for money to get away.
From 2011 and onward, my family had fallen into bankruptcy for paying out of pocket for my older brother’s medical expenses and surgery costs due to his diagnosis of heart failure. In 2013, when I took the standardized ACT exam two times, I scored both times an 18 which was below my university’s 2014 entering freshmen class’s composite score average of 24.5 (copy of score report is attached). Furthermore, upon taking the LSAT two times with over four months of self-studying for the September exam, I scored first a 141, and a 140 on my last attempt. When taking both examinations, I have not been able to afford tutoring pertaining to the exams or a preparation course. Although I have worked numerous jobs during the past few years in college,
There are so many reasons that lead me to chose this particular topic.I have been following the MMA for couple years , and also I am comfortable with sports platforms.
1.“If, for example, students were not ultimately rewarded for spending their early adulthoods pursuing undergraduate, graduate, and professional degrees, or if the hardest-working and most productive workers were paid the same as the median worker, then citizens would have little incentive to develop expertise, to exert effort, or to excel in their work.”
when I was making my john cena math game I wanted an image of john cena for the home page but most of the ones I looked at were copyrighted and owned by other people so I used the option to google images search but on show images that were available for reuse with modification so I could change john cena around in case he wouldn’t fit in my game screen. I had a problem similar to this when I was looking for images for my website but I used creative commons search to find god images I could change around in Photoshop to create a banner for my website and I wouldn’t get caught for stealing someone’s image without their permission. When I was writing some of the parts for my conceptual design of my website I had to make sure none of it was copying form other people or it would be called plagiarism and it would get me in lots of trouble at school, to get around this I put it in my own words and just to be sure I ran all my work through a plagiarism detector on www.plagtracker.com to make sure none of it was still plagiarism. Plagiarism is a big issue because you could just copy someone else’s work of the internet without asking or acknowledging them and that’s low to the person who did the work because you’re getting credit for their

The moral philosophy best describes my personal decision making is virtue ethics (Ferrell, Fraedrich, & Ferrell, 2013). It best description of me as virtual ethics having exceptional moral character (Ferrell, Fraedrich, & Ferrell, 2013). My character displays honesty, integrity, and helpfulness (Ferrell, Fraedrich, & Ferrell, 2013). For example, a friend attempted to commit suicide as a result of a wife asking for a divorce through email (Ferrell, Fraedrich, & Ferrell, 2013). However, while working I received a phone call from him stating his desire not to live anymore (Ferrell, Fraedrich, & Ferrell, 2013). Meanwhile, I called his son to ensure that he wasn’t alone however, his son drove to the house and found his father sitting and with a
America is dub the land of opportunities and hope by all that look from the outside of the fence in. The shining image of greatness America portrays gives the sense that you can accomplish anything when within its diverse borders. I’m Māori Johnson, and I’m a naturalized citizen of the United States of America from Jordan. Naturalization is defined by the U.S Citizenship and Immigration Service (2013) as the process by which U.S citizenship is granted to a foreign citizen. It’s a rigorous thing to accomplish which consist of first applying for citizenship, if accepted you then go through a written test and exam, probably most natural born citizens couldn’t pass. After you’re accepted life isn’t the easiest to begin. I’ve had to leave behind my job in my former country to pursue my new life here. I am pursing a master’s degree in communications from Texas State University to better my opportunities here. However, I’m working at a local H-E-B while I attempt to pursue a career in my area of expertise while attending school. I’ve expected to have a hard time adjusting in that aspect but I’m enjoying my time here. (Question 1)
According to Hirsch at the Centers for Disease Control and Prevention (CDC,2014), “more than 1.1 million people in the United States are living with HIV infection. Almost one in six of this group are unaware that they are infected”. Not knowing that you have a HIV is a bad thing because it not good to wait so late to have test done. Some symptoms of the early stage of being infected with HIV are deeply pained headaches, very high fevers a sweating a lot. The sweating and fever could lead to Flu or mononucleosis, which could make the whole infection even worse. Bad thing about this infection the first month or two the symptoms go away after that. During the early stages of being infected a person is very infectious. Some of the symptoms

Preventive maintenance can be defined as an activity performed on a certain schedule which is intended to prevent breakdowns or deterioration. These activities can include regular inspection along with solving any discovered problems or situations and regularly scheduled parts changes. Preventive maintenance involves the scheduled adjustment, inspection, replacement of wearable parts, calibrations, basic cleaning and lubrication of equipment or other recommendation made by the equipment manufacturer. These activities can help increase the equipment functional life and help decrease facilities deterioration. No equipment should, No equipment should reach the breaking point [1].
