BIOS For Beginners “BIOS for Beginners” explains just how essential the BIOS is for any standard personal computer built today. The BIOS which stands for the Basic Input Output System is a chip installed directly on the motherboard and acts as the middle man that gives commands between the hardware and the operating system. Having incorrect settings on the BIOS can slow your computer down nearly in half which is why it is so important as a technician to understand how it works and the importance of each function it provides. As processors advance, the more complex the BIOS becomes as well often leaving even experienced computer technicians scratching their heads. Any wrong move when altering settings can lead to your computer malfunctioning. If this happens, you may need to completely reset the BIOS to the factory settings using the jumpers built in on the motherboard. “It is recommended that you reboot after each individual BIOS setting change to ensure that your system functions normally. If you make numerous changes before rebooting, and your system will no longer boot, you won't know which change is responsible for the failure,” http://www.tomshardware.com/reviews/bios-beginners,1126.html. To enter the BIOS in most computers, you will be using the F1, F2 or DEL button to enter the system. However, there are sometimes a couple other options as well given from a list of options when accessing damages and repairing the computer. Some of the options available for change within the BIOS include the date, time, boot order, fan speed, disabling drives, power management setup, PnP/PCI configuration and many other choices. As said before the BIOS can be very complex where even the appearance and functioning of each system changing. You can have one system where the mouse is optional and you may have a more modern interface to work from. Most BIOS’ seem to work from a stone age view point only allowing you to move around using the arrow cursors and the enter and delete key which some computer professionals actually prefer. Lastly, the BIOS is a place to set a last line of defense for your computer allowing you to adjust a system supervisor and administrative password which will make it so a password must be entered to even boot the operating system making it harder for thieves to steal valuable information or to hijack your computer. The only way to get pass this one would be to actually replace or wipe the BIOS chip so don’t forget it. Each BIOS chip is usually built very differently from their competitor’s chip making it very unique for ever changing options and the view of the interface, however the main job of the BIOS is ultimately similar, to make sure all components of the operating system work in sync with the hardware.

C 351 Yot2 Task

...C351 YOT2 Task 1 Running Head: C351 Task 1 C351 YOT2 Task Amanda Drucker Western Governors University C351 YOT2 Task 2 A. Professional Presence Human, a word many use each and every day, most of the time without thinking of the meaning of the word. Of course there is a definition which one can find in any dictionary or encyclopedia, but the meaning, that is something that has evolved and continues to change each and every day. In fact the meaning of the word human can be described differently by nearly everyone who is asked. Dr. David Livingstone Smith, an associate professor at University of New England, states, “ answering this question is not as straightforward as it might appear,” when asked, what it means to be human (Smith, 2012). It can therefore be said that as the definition of being human changes and evolves so does the way we care for others in medicine. Dr. Larry Dossey describes three eras of medicine, each evolves from ideas of the previous and has changed over the years. In the first era, medicine has a “mechanical” approach which only involves drugs, procedures, and surgical intervention (Dossey, n.d.). In era two Dr. Dossey discusses a change that began to appear in medicine, that is, “that disease has a ‘psychosomatic’ aspect: that emotions and feeling can influence the body’s functions,” (Dossey, n.d.). Finally in era three it is said that, “ an individual’s mind may affect not just his or her body, but the body of another...

Andrew Lloyd Webber

...w A Reflection on Andrew Lloyd Webber By: Evan Emerson June, 20 2012 I am hooked on Broadway, for life! Touched by The Phantom of the Opera (1986), the first time I saw it was age 14. Andrew Lloyd Webber has won seven Tony Awards, four Grammy Awards, a Golden Globe Award, and an Academy Award; just to name a few 1. Andrew Lloyd Webber does not need our recognition – his legacy has already impacted millions worldwide! Webber is an accomplished composer. His success is exemplified by his passion for musical theater, smash hit The Phantom of the Opera (1986), and his continued support for the arts through the Andrew Lloyd Webber Foundation. I am inspired by Webber’s moving musical compilations and compulsion to press further even after making millions. Even at a young age, Webber knew what he wanted to do with his life. By the age of three, Webber showed an immense aptitude for the piano, but his mother stated “All the pieces he was supposed to play, he wouldn’t touch. He wanted to play his own tunes, and no others2.” I am profoundly impressed by Webber’s knack for knowing himself, and his drive to pursue his absolute passion in life. There is much wisdom to learn from someone who does what they love, and loves what they do! As I briefly stated, “Phantom” was my first introduction to theater. I have seen it 11 times since, not even including the film adaptation (2004). Needless to say, “Phantom” is my absolute favorite musical! Webber’s The Phantom of the...

...o there are many issue with wireless devices, I am going to discuss and also going to throw light on new possibilities. These are main 4 Issue with wireless technology we are having these day 1. Capacity We are transmitting these wireless data in form of radio wave, we all knows these are limited, scarce, and expansive and no hope for further expansion as per our need. These limitation is not able to full fill our current monthly data transmission demand and we are no doubt running out of spectrum. 2. Efficiency There is another problem, efficiency. These base stations consume lots of power every hour. Interesting thing is that most of the power is not used for transmitting radio waves, but to cool down the base stations. Thus efficiency of such base stations is only about 5%, that means a big problem. 3. Availability You can’t use your wireless devices in your Flight, hospitals, in military prone areas for security issue. 4. Security Security is another issue, these penetrating and scattering radio waves have no controls in boundaries, they goes off the range we use, even consumes power too. Even somebody can make misuse of these radio waves, Looking to another corner, we have 20 billion of Light bulbs deployed across the world in current infrastructure. That’s what I am going to cover in my post. We have electromagnetic spectrum, where we have Radio waves and visible light, Comparing their availability, bamm, we have 10,000 times more visible...

Concept Analysis Competency

...Competency: Analysis of the Concept Michelle Trigg University of South Alabama Abstract Understanding the nature and meaning of nursing competency is the initial step in having an unambiguous definition of its practice. All healthcare professionals, including nurses, may only prove to be proficient in their capabilities if they are able to perform comprehensive assessments related to the provision and maintenance of safe and efficient care, the protection of all members of the general public, and the undertaking of all necessary actions in order to preserve the nursing profession. Any and all standards that are established, based on such a perspective, must be adhered to in practice and for the purpose of nursing evaluation. This paper will evaluate and explore the concept of competency and the ways in which the nursing profession integrates the many aspects of competency.

Between current economic conditions and the technological evolution of the Internet, the traditional approach most job seekers have taken in the past is no longer viable. The approach — developing a resume and cover letter, locating jobs on and submitting your resume to corporate sites and job banks, and crossing your fingers in hopes of receiving a call from a hiring manager — is, for the most part, a thing of the past. The new approach is far different. It boils down to the fact that there are fewer jobs available, more competition for those jobs and more touch points for recruiters and seekers to interact. The current environment In 2008, there were 1.2 million , unemployment is currently at 6.5%, and the largest companies are shedding as much as 10% of their workforces. There will be 1.5 million college graduates this year, yet the _ is at a six year low, at 1.3%!
