...RELIABILITY and PERFORMANCE Through RAID Structures Casundra Gilder Southern New Hampshire University July 18, 2013 Abstract Redundant Arrays of Independent Disks (RAIDs) are used to address performance and reliability of disks. RAIDs are just a large number of inexpensive disks that can be linked together to create one single large storage space that offers better performance, reliability and storage capacity for older systems. RAIDs have become more popular over the years and increasing common with end user systems. There are many levels of RAIDs that are in existence today. With the creation of RAIDs, more computer systems have become better as far as increased performance and redundancy. Redundancy is one of the most important factors when it comes to developing RAIDs for server environments. When a drive fails on a system, a user can either change the old drive for a new one without having to power down the system or a RAID could be used. All redundancy methods depend on the version of RAID used. Performance of a system will depend on the number of drives used in the array and the controllers and increased performance can only be located when specific versions of RAIDs are used. There is a limit to the rate at which data can be read from or written to a hard disk platter. By implementing a RAID, a single disk will have increased performance when it comes to reading and writing to multiple disks at the same time. RAIDs handle hard disk drive failures...

...students. In the 21st century where technology rules, it is important to incorporate it as much as possible into whatever lesson they a teacher is teaching. In this paper, I will tell you how to integrate instruction technology into your classroom, give the pros and cons in using technology to facilitate learning and the difference between wired and wireless classrooms. The right technology has the ability to grab and hold the attention of children at any age. There are several ways to integrate instructional technology into the classroom. One way to integrate technology in the lesson is by using the SMARTBOARD. The SMARTBOARD gives a teacher access to the internet with a wide range of text, graphics, audios, videos and animation (p.242). It is also a tool that students can interact with. The SMARTBOARD has taken the 21st classroom to a whole new level. In the past and probably still present in some places today, the chalk board or dry erase boards are still being used. The smell from the markers is not good for all students and the chalkboards are very messy. The SMARTBOARDS are clean and there are no strong smells. The only down side to a SMARTBOARD is that the teacher will have to spend a lot of time surfing the web to get the right material for their students to see. Another way to integrate technology into the classroom is to have the students complete a project on the computer. Students could create historical timelines, charts about famous people, research paper...

... word-of-mouth, costly advertising, and marketing campaigns, and face –to-face networking. Because of social media sites, such as Facebook and Twitter virtual worlds can accommodate businesses in the real world. Customer relationships in a virtual world are a delicate matter. The design of a web site is very important for presenting a favorable face to the customer. Similarly, the design of a business in SL is of chief importance. In a world where anything-goes design-wise, how do you want your customer service representatives to appear? The business must present something fantastic, that it could not present in the real world, if it wants to draw visitors into it. Second Life provides a medium for simulating real world interactions online. It has the same benefits as teleconferencing or videoconferences, the ability to assemble many people from all around the world into real-time interactions. NPR’s Science Friday makes great use of this tool, hosting a studio audience in SL that they couldn’t otherwise support. Public speakers also benefit. I once attended a talk by a favorite science fiction author who would not have attracted enough of an audience in any one local, but SL was perfect for finding enough interest from around the globe to come up with a great turn out. Being a virtual world, Second Life is much less about providing the visitor...

Now bison have been exterminated in the wild except in Yellowstone Park in Wyoming and Wood Buffalo Park, Northwest territory, Canada. The bison are gone in the prairie of the United States along with many of the ecosystem's species. Deep scars mar the landscape where the soil has been swept way by water runoff. The life of the rancher and farmer is vanishing. The body of the bison is huge. They are also tall animals and have two distinctive features, one being the shoulder hump and the other being their huge head. They are brown, their color varying slightly from the front and back of the animal. Their horns are black and curve upward and inward ending in a sharp tip. Their legs are short but firm. Bison are year round grazers. They feed primarily on grasses, but when food is scarce, the will eat other vegetation such as sagebrush. They require water every day. Females are sexually mature in two to three years . The breeding season begins in late June and lasts through September. Gestation is around 285 days, so the calving season in from mid-April through May. Bison are arranged in groups according to sex, age, season and habitat.

...technological development. In the 90’s the CSIRO innovated this technology to todays standard. More than 20 different tech companies paid 250 million dollars for the equipment and Australia is still waiting for a payment estimated over 1 billion dollars. There have been many revolutionary browsers which have aided in the revolution in the World Wide Web and the Internet its self. The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities. The numbers have changed to over 1.5 billion users. The network's reach has expanded beyond the United States to all over the globe. But everything has its pros and cons, as it has evolved from a friendly research network to a hotbed of criminal activity including fraud and identity theft. Ideas for the World Wide Web date back to as early as 1946 when Murray Leinster wrote a short story which described how computers (that he referred to as ‘Logics’) lived in every home, with each one having access to a central device where they could access information. Although the story has several differences to the way the web works today, it does capture the idea of a huge information network available to...

...scientists claim that GMOs are completely safe for human consumption. GMOs should be banned because they have a negative impact on human health, and potential risks on the environment. Although GMOs were only introduced in 1996, the side effects can already be seen: there have been increased allergic reactions, antibiotic resistant bacteria and other toxic hazards. While these side effects of GMOs may seem minuscule in the grand scheme of things, the lasting effects can be much more drastic. More and more children are having life-threatening allergies, which can be contributed to increased GMO intake. Children that have been born with birth defects have been associated with the chemical, glyphosate. Glyphosate is an herbicide used to kill a wide range of weeds. This chemical alone can cause infertility, stillbirths, miscarriages and cancers. Researchers found that glyphosate “caused malformations in frog and chicken embryos that were...
