...Summary Read-Only Participants: A case for student communication in online classes. Online learning is conducive to that of the traditional onsite learning facilities. There are some students who fully participate in the experience as well as those who take their learning environments for granted. A summary of the required reading “Read-only participants: a case for student communication in online classes” will support the noted claim. The study was completed to measure the various behaviors of the online learner. The research gathered the behaviors of students participating the in a Master’s degree web-based curriculum through the University of Pretoria. Beaudoin is noted as one of the greatest contributors to this case study. The study was broken into various parts. To support the introduction and conclusion of the study, the body included: Background, Literature, Context of this study, Methodology, and the Discussion. A breakdown of each subtopic of this study will be discussed in this summary. I have taken several online classes prior to reading this study and I found it to be very supportive to my conclusive evaluation of the practice. Although this study was completed in 2009, I can relate that my prior experiences in online classes were parallel to the researcher’s findings. The introduction made the reader aware that there are challenges to online learning and that “the establishment of an online community is widely held as the most important prerequisite...

..."Read-Only Participants: A Case for Student Communication in Online Classes" In the article titled "Read-only participants; a case for student communication in online classes" impairs the importance of community and communication in online courses. It also discusses the reason students succeed or fail in online classes. To discover the concerns listed above, a study of eight weeks was conducted on students. The study monitored classroom activity as well as communication among students coming from diverse backgrounds. Such examples are geographical location, race, gender and age. The study resulted in both success and failure. Both were discovered and documented. With the results of success the following findings were noted: firstly online courses that had discussions where students and teachers would interact had a positive effect on introverted individuals. In a traditional classroom these students would have participated less but now found a voice in the virtual classroom. Secondly, the skills necessary in an online classroom can improve higher order thinking as well as critical thinking. This was done by the discussion forums and posts that required students to apply and create learned knowledge. Thirdly, a professor that had great involvement with his class became a positive feature by providing encouragement and support through posts. As a result of the instructors involvement students were eager to become more involved in the discussions. In addition to results...

...Canyon University: UNV 501 6/25/2012 A Case for Participation in Online Courses Online computer courses/degrees are becoming more frequent as technology improves and the availability of technology is greater. This article “Read-only participants: a case for student communication in online classes” (Nagel, Blignaut, Cronje 2007) analyzes data from several studies and suggests that active participation, as opposed to non-active participation, is directly correlated to student achievement. Read-Only Participants The term Read-only participants refers to online students who log into a specific classroom website, read the material provided or student post’s but do not get actively involved in the discussion. Buedouin (2002) suggested that read-only participants can learn and succeed in an online setting without participating (Nagel, Blinaught, & Cronje, 2007). However research by: Nagel, Blinaught, & Cronje (2007); Klemm (1998); Rovai & Barnum (2003); Swan, Shea, Frederickson, Pickett, & Pelz (2000), indicate that participation is essential to be a successful online student. Read-only students also have the tendency to create a negative environment within an online learning environment, with other having the perception that the read-only student does not care and does not want to contribute. This is extremely evident when they are in a collaborative learning environment and participation in a project by all involved is essential for the group’s success. This...

..."Read-Only Participants: A Case for Student Communication in Online Classes" In the article written by Lynette Nagle, Seugnet , and Johannes Cronje "Read-Only Participants: A Case for Student Communication in Online Classes" they talk about a wide array or reasons why students have done well or run into some learning barriers while taking online courses. As a professor with a Ph.D. in Computer-Integrated Education, Nagel understands participation in an online course and staying current with all assignments was what they needed to become more self-driven, empowering there initiative and interacting more freely between the other students along with them. Such as, in this course we learn and write about topics posed to us for all to see and read. We also form a dialogue/debate amongst each other with our responses. Once completed, the study which involved an eight week long elective course that encompassed a wide range of age groups along with different socio-economic and geographical areas, Nagel’s theory proved to be correct. That when it came to the course or assignments given, not all participants had to be involved with the other students or professors, but it was key to have open forums for discussions and debate with all the members of the class. Virtual classrooms were shown, having online areas where students could have discussions, not only yielded positive results from the students that are doing well in the class to forming a sense of unity and bond with everyone...

...measured showed highly significant differences between the stratifications of student performance, there were notable exceptions unexplained by the trends. The class harboured a well-functioning online learning community. We also uncovered the discontent students in the learning community felt for invisible students who were absent without reason from group assignments or who made shallow and insufficient contributions. Student online visibility and participation can take many forms, like read-only participants who skim over or deliberately harvest others' discussions. Other students can be highly visible without contributing. Students who anticipate limited access due to poor connectivity, high costs or other reasons can manage their log-in time effectively and gain maximum benefit. Absent and seldom contributing students risk forsaking the benefits of the virtual learning community. High quality contributions rather than quantity builds trust among mature students. We suggest how to avoid read-only-participation: communicate the required number of online classroom postings; encourage submission of high quality, thoughtful postings;...

...Let’s start by looking at one of the first computer operating system MS-DOS was and still is a single tasking operating system which created in 1980 and used up until 1990 when windows 3.0 came out which was considered a multi tasking but very slow the first pc was introduced August 12, 1981. It was the size of a portable typewriter and contained 40K of read-only memory and 16K of user memory, as well as a built-in speaker for generating music. But in time over the years the pc has developed smaller and faster by 1000’s fold. The task manager manages one program or many programs within a computer system simultaneously. A task management program in an operating system provides each task and interrupts the CPU operations to manage tasks efficiently. When you use the task manager to see all of the processes that are running you may see a process that is using a large amount of the CPU process and you can end the process in the task manager, the control over the CPU varies with each process some demand more power than others. There are many ways for a person to increase the power and capability of a computer for example one can upgrade the memory to a higher amount or upgrade the memory to a higher amount also. You can also use various programs that can improve the speed and performance of a computer, References Uknown, (2012, June 4). operating system.

...surveyor to use a recording with this device allowing for less use of man labor, making it far more cost effective, accurate and faster. The voice recognition software stores the information directly into a computer hard disk. This approach assures accuracy by eliminating the potential for human recording errors. Translation errors may occur however, if the voice recognition software is not adjusted for the speech of the interviewees. When using this method of data input we should always keep in mind that some people only respond to live operators. As for bank checks the most accurate method is the MICR, Magnetic Ink Character Recognition, developed by the bank industry. “Data is placed on the bottom of a check or other form using a special magnetic ink. Data printed with this ink using a special character set can be read by both people and computers” (Stair, R. & Reynolds, W.G., 2006, p.37). For retail tags it would be the barcode scanner uses a laser to read the barcode label accurately.

...that hackers can use when RAM hacking, which include several programs and utilities. The most common tools of RAM hacking is Nmap and Metasploit. Nmap, also referred to as the swiss army knife of RAM hacking or any other hacking, is one of the best effective port scanner tool numerous functions. In its hacking, Nmap is used in a footprinting phase to scan the ports of the remote computer, where it finds out which ports are open in order to compromise their access. Metasploit, on the other hand, is also an effective tool in RAM hacking as it commands a large database of exploits. In addition, it offers thousands of exploits codes that are useful on attacking web servers and computers (Levy, 2010, p.28). This is a hacking tool that hacks not only the RAM, but the almost entire part of a computer. Hackers always attack and succeed where they see weaknesses. In this case, there are various practices that can be used as precautionary measures to prevent any eventuality of being hacked. In this case, three crucial practices will be discussed in this context. These practices include; performing required software updates for web browsers and operating system, installing a firewall on the computer, and installing of anti-spyware or...

...between the computer's operating system and attached devices such as the hard disk , video adapter , keyboard , mouse , and printer . BIOS is an integral part of your computer and comes with it when you bring it home. (In contrast, the operating system can either be pre-installed by the manufacturer or vendor or installed by the user.) BIOS is a program that is made accessible to the microprocessor on an erasable programmable read-only memory (EPROM) chip. When you turn on your computer, the microprocessor passes control to the BIOS program, which is always located at the same place on EPROM. When BIOS boots up (starts up) your computer, it first determines whether all of the attachments are in place and operational and then it loads the operating system (or key parts of it) into your computer's random access memory (RAM) from your hard disk or diskette drive. With BIOS, your operating system and its applications are freed from having to understand exact details (such as hardware addresses) about the attached input/output devices. When device details change, only the BIOS program needs to be changed. Sometimes this change can be made during your system setup. In any case, neither your operating system or any applications you use need to be changed. Although BIOS is theoretically always the intermediary between the microprocessor and I/O device control information and data flow, in some cases, BIOS can arrange for data to flow directly to memory from devices (such as video cards)...
