The Power On Self Test
When the system is powered on, the BIOS will perform diagnostics and initialize system components, including the video system. (This is self-evident when the screen first flicks before the Video Card header is displayed). This is commonly referred as POST (Power-On Self Test).
Afterwards, the computer will proceed its final boot-up stage by calling the operating system. Just before that, the user may interrupt to have access to
SETUP.
To allow the user to alter the CMOS settings, the BIOS provides a little program,
SETUP. Usually, setup can be entered by pressing a special key combination (DEL,
ESC, CTRL-ESC, or CRTL-ALT-ESC) at boot time (Some BIOSes allow you to enter setup at any time by pressing CTRL-ALT-ESC). The AMI BIOS is mostly entered by pressing the DEL key after resetting (CTRL-ALT-DEL) or powering up the computer.
You can bypass the extended CMOS settings by holding the key down during boot-up. This is really helpful, especially if you bend the CMOS settings right out of shape and the computer won't boot properly anymore. This is also a handy tip for people who play with the older AMI BIOSes with the XCMOS setup. It allows changes directly to the chip registers with very little technical explanation. A Typical BIOS POST Sequence
Most BIOS POST sequences occur along four stages:
1. Display some basic information about the video card like its brand, video BIOS version and video memory available.
2. Display the BIOS version and copyright notice in upper middle screen.
You will see a large sequence of numbers at the bottom of the screen. This sequence is the .
3. Display memory count. You will also hear tick sounds if you have enabled it (see Memory Test Tick Sound section).
4. Once the POST have succeeded and the BIOS is ready to call the operating system (DOS, OS/2, NT, WIN95, etc.) you will see a basic table of the system's configurations: · Main Processor: The type of CPU identified by the BIOS. Usually Cx386DX,
Cx486DX, etc..
· Numeric Processor: Present if you have a FPU or None on the contrary. If you have a FPU and the BIOS does not recognize it, see section Numeric Processor
Test in Advanced CMOS Setup.
· Floppy Drive A: The drive A type. See section Floppy drive A in Standard
CMOS Setup to alter this setting.
· Floppy Drive B: Idem.
· Display Type: See section Primary display in Standard CMOS Setup.
· AMI or Award BIOS Date: The revision date of your BIOS. Useful to mention when you have compatibility problems with adaptor cards (notably fancy ones). · Base Memory Size: The number of KB of base memory. Usually 640.
· Ext. Memory Size: The number of KB of extended memory.
article # 1 it gives you tips on what to do if your computer is not turning on. I learned that sometimes the USP and others are not plugged in the right way and sometimes people can trip over to make them unplug a little. My mom has a computer and her computer never turns on so she checks if her cords are plugged in properly and it turns on.

Windows hardware’s has played a vital role in current technology of computer era. Computer application has significantly changed the workloads and manual records and information keeping has been significantly managed easily. This has been tremendously associated with the respective improvements with the software and hardware application development and Windows Xp and windows 7 have been most powerful operating system used by many computer applicants and users.
Symbolism is very important in Oscar Wilde's "The Importance of Being Earnest." It is the symbolism that mocks the upper-class of the Victorian Era. Without comprehending and embracing the symbolism of the story, the story cannot make sense. But with context and accurate understanding of the symbols used, the story's message is a powerful one. Some symbols used in the story are food, Lady Bracknell, and the act of Bunburying.
The Beck Anxiety Inventory was designed by Aaron T. Beck and is self report scale that consists of 21 items. The items are short and straightforward, making it easy to read and comprehend. All items are related to anxiety and describe a symptom of anxiety that is rate on a four point likert scale according to severity. The answers range from 0-3 and the responses range from “not at all” to “severely; I could barely stand it” and all items are added for a total score. The instructions on the test ask for the respondent to “indicate how much you have been bothered by each symptom during the past week, including today, by placing an X in the corresponding space in the column next to each symptom” (Dowd, 2008). The assessment is intended for adolescents and adults and can be administered individually or in a group setting. An additional copy of the inventory test is also available in Spanish. It was originally created from a sample of 810 outpatients of that were predominately affected by mood and anxiety disorders and research on the original development is described as informative and thorough.
Well, Before anything else, here is a few names of components that need to be known to not be completely lost. The CPU(Central Processing Unit) (It processes everything from basic instructions to complex functions.) (Techterms.com). The Hard drive (the location of all the computer’s folders, files, and information, saved magnetically so even if turned off it’ll all stay saved). The RAM (Random Access Memory) (The more RAM your computer has, the more data can be loaded from the hard drive into the RAM, which can effectively speed up your computer.)(Techterms.com), The OS (Operating System) (just what it sounds like, this is the system that works the computer, as in Windows, Linux, and Apple OS.) The Graphics card (helps the CPU by processing the graphics portion of what the CPU has to process). The Disk Drive( this is the CD,DVD, or Blu-Ray driver that is installed to use CD’s DVD’s and or Blu-Ray disks.) The last major term to know is the Motherboard ...
Choosing which motherboard to use is important. It also is closely related to what processor is chosen. Because of cost saving factors, the AMD Athlon processor is the best choice. Therefore we can only provide a motherboard compatible with the AMD AthlonXP 1900. For our client, we decided on the motherboard Aopen K77-333. This motherboard is an excellent choice for our client because:
Its Fourth-generation quad-core Intel Core i7 processor is remarkable for good performance and visuals. It enables the user to feel and see in high definition and 3D; and gives room for multitasking and media. The thrilling speeds are modeled for smooth and seamless games, photos and movies. The chip has a transistor count of 1.4 billion and a die size that is 177 square millimeters. Additionally, it has an incorporated processor graphics, and a dual-channel DDR3 support of up to 1600MHz (Williams & Sawyer, 2010).

What I knew about my computer was how to turn on and off by pressing the big button at the bottom of my computer. I turned on the computer and had no idea what to do next, but I was still happy. I just clicked on everything and did not know how t o go back to the previous screen. Whenever I had problems with my computer, I just turned off the computer. It was pretty simple to clear my computer problems by pressing the power switch. The power switch was a problem solver.
A storage device is the system where your computer stores and retrieves your data. Storage devices can be a hard disk drive, DVD, CD drives, Blu-Ray drives or flash drives. A computer can retrieve the data by being “commanded” to retrieve it from the storage area and retrieve it to your RAM. The RAM of the computer is your temporary memory where your data is inputted, and then processed and stored onto a storage device for permanent placement.
computer architecture Computer architecture covers the design of system software, such as the operating system (the program that controls the computer), as well as referring to the combination of hardware and basic software that links the machines on a computer network. Computer architecture refers to an entire structure and to the details needed to make it functional. Thus, computer architecture covers computer systems, microprocessors, circuits, and system programs. Typically the term does not refer to application programs, such as spreadsheets or word processing, which are required to perform a task but not to make the system run.
