It checks all of your hardware to ensure they all have power and are working. BIOS is actually firmware, the software that is programmed into a ROM (Read-Only Memory) chip on the motherboard of a computer. BIOS is something that makes the system run on an initial Power-On Self-Test of the computer, initialize circuits, load the boot program from the startup disk, and then handle low-level I/O peripheral controllers such as keyboard and screen. It has several different categories; you can see your BIOS by paying attention to the screen when it first starts up, there will be a screen with few seconds duration. The BIOS is typically placed in a ROM chip that comes with the computer (it is often called the BIOS ROM). This ensures that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Because RAM is faster than ROM, however, many computer systems design manufacturers so that the BIOS is copied from ROM to RAM each time the computer is started. This is known as shadowing. Many modern PCs have flash BIOS, which means that the BIOS have been recorded on a flash memory chip, which can be updated if necessary. The PC BIOS is fairly standardized, so all PCs are similar at this level (although there are different BIOS versions). Other DOS functions are usually added through software modules. This means you can upgrade to a newer version of DOS without changing the BIOS.PC BIOS that can handle Plug and Play (PnP) are known as PnP BIOS-es, or PnP BIOS current. These BIOS-es are always implemented with flash memory rather than ROM. CMOS Semiconductor complementary metal oxide (CMOS) is a type of semiconductor chip that holds data without requiring external power source. In a personal computer (PC), CMOS has the basic instructions the computer needs to initialize its hardware and start-up. These settings are known as the basic parameters of input-output system (BIOS), also called the CMOS settings. CMOS control a variety of functions, including the Power on Self Test (POST). When the computer power switched on, CMOS will run a series of controls to ensure that the system works properly. One of these controls includes counting memory (RAM). This start-up time delays, so some people disable this feature in the CMOS settings, opting for a quick start. If you install new RAM, it is preferable to activate until the RAM has been verified. Once POST has completed, CMOS runs through its other settings. Hard drives and formats are detected and Redundant Array of Independent Disk (RAID) configurations, the start-up preferences, the presence of peripheral and tweaks for over clocking. Many parameters can be changed manually in the CMOS setup screen to improve performance. However, changes must be made by experienced users. Changing the settings wrong can make the system unstable, causing accidents, or even prevent the computer from starting. The CMOS setup screen is accessed during the POST phase mode, by pressing a button before the operating system boots. Normally it is the Delete key but it could be another. A line of text will indicate which button the user in the CMOS or BIOS setup screen. Changes can be made from an operating system like Microsoft Windows, but must be done in a true DOS session. There is also an option to protect the CMOS settings by requiring a password to change settings. The changes are saved to the output by pressing the F10 key, and then the computer restarts to use the new settings. The system uses what is called a CMOS Checksum error code as a detector. Whenever you change the BIOS settings, the checksum is generated by adding all the bytes in the CMOS memory, then store the lowest byte of the sum. Then, whenever the system is booted, the system recalculates the checksum and compares the stored value. If they are different, the system knows that the CMOS has been corrupted in some way and will notify you via an error, usually something like CMOS Checksum Error. There are many different types of batteries used to power the CMOS, for the most part; they have evolved over time as technology has evolved. These batteries are discussed here. You will not normally deal with the CMOS memory directly; it contains the parameters that you enter the BIOS setup. Over time, it is possible that you have problems CMOS, for example, you may find that the machine can begin to forget its settings when it is started. These are usually signs of problems with the battery on the moth erboard.

WHAT IS THE DIFFERENCE BETWEEN BIOS AND CMOS? Many people use the term BIOS (Basic Input / Output System) and CMOS (Complementary Metal Oxide Semiconductor) interchangeably, but in reality, they are distinct, yet related, components of a computer. The BIOS is a computer program that starts up, and the CMOS is where the BIOS stores the date, time and details of system configuration needed to start the computer. The BIOS is a small program that controls the computer from the time it powers on, until the time the operating system takes over. The BIOS firmware, which means its, cannot store the variable data. CMOS is a type of memory technology, but most people use this term to refer to the chip that stores data variables for booting. A computers BIOS to initialize and control components such as controllers and hard disk drive and the computer hardware clock, but the specific parameters for the startup and initialization of components are stored in CMOS.In addition to the standard CMOS memory used to store system settings, BIOS Plug and Play use a nonvolatile memory upgrade to keep the extended system configuration data (ESCD). It is used to save the configurations of the devices of system resources when Plug and Play is used. Type of BIOS Phoenix IBM AMI Award Type of CMOS Battery Coin Cell Batteries PS2 Computer Clock Battery BIOS AND CMOSS FAILURES AND HOW TO FIX THEM CMOS checksum error mostly will occurs when CMOS values was incorrect. There is few option may occurs the failure as below. Bad or old CMOS battery. BIOS update. Removing power from the computer without shutting down the computer. POST errors. The Solution Bad or old CMOS battery: Try restarting the computer. If the error persists after restarting the computer to enter the CMOS setup and check all values, which include verifying the date and time are correct. Once everything has been checked and / or changed be sure to save and exit the CMOS setup. If everything looks correct and the problem persists try resetting the defaults in CMOS and / or Reset Configuration Data. Additional information on how to proceed can be found on document CH000976. Note: If this problem persists after you turn off your computer off, it is possible that the CMOS battery may be faulty or already ill. Before consider on replacing the CMOS battery to try to leave your computer on for several days. Additional information on replacing the CMOS battery can be found on document CH000239. Computer badly off: If the computer had been disconnected the power while still running it is possible that this may cause the CMOS to be corrupted. Make sure the computer is ready to be cut before turning off the computer. If you have a laptop so that battery is charged before disconnecting the electrical connection. If the CMOS values have been damaged by entering values in the CMOS setup and saving CMOS and the output should solve your problems. Additional information about entering the BIOS setup can be found on document CH000192. BIOS update recently completed: if youve recently released a BIOS update on the computer values stored in the CMOS can be reset. Enter CMOS setup and re-enter all the appropriate values. Additional information about entering the BIOS setup can be found on document CH000192.If you are unable to enter the BIOS or after the execution of a BIOS your computer is no longer values the incorrect BIOS update may have been installed on your computer or the downloaded version may be corrupted. We suggest you try to update the BIOS and / or go back to an earlier version. Additional assistance and information with the BIOS updates can be found on document CH000236. POST error: Each BIOS manufacturer has its own diagnostic codes to identify specific errors. You need to consult the documentation for specifying the BIOS beep codes. Many motherboard manufacturers will use code similar to the original IBM POST codes, which are summarized in the table below. If you get a single beep, all is good. In some cases, these beeps are also accompanied by a diagnostic code; you also look in the BIOS documentation.

the scarlet letter c- :: essays research papers

Since the dawn of man people have been challenged by evil. Whether it was Eve eating and than offering the apple to Adam, or the Caveman murdering his neighbor for personal benefit. Using Nathaniel Hawthorns novel The Scarlet Letter we can see how evil consumes someone’s day to day live even if it is filled with the morals brought fourth upon them by their god. Three of the four main characters in this book were sinners who were faced with evil and chose to suffer, combat, or bargain with it. With good intentions the townspeople also played a role letting evil exist with the intentions of stomping it out. In the 1600’s because of fear from their vengeful god Puritans tried to be moral and just. They chose a life where the 10 commandments was the law of the land and there was no exception. The sixth commandment Thou Shalt Not Commit Adultery was not a rule that people ignored. With the intentions of comforting Hester Prynne’s lonesomeness and grief for her missing husband, Arthur Dimmesdale became passionate. They both shared intimacy knowing the result was not praised in Heaven. She later found that she was pregnant and our novel begins to show a struggle between good and evil. After Hester Prynne’s child was born, she was forced to take her walk of shame out of the prison doors to stand on a Scaffold to be publicly humiliated. The townspeople in the marketplace were astonished that a woman can let her lust overwhelm her into the point of adultery. Harsh statements came out of their mouths. â€Å"`At the very least, they should have put the brand of a hot iron on Hester Prynne’s forehead. `Said one of the angry puritans† (1360). The townspeople have good intentions by trying to teach others that Adultery was a sin yet are doing the work of the Dark Man. By mentally crucifying this woman and making her wear the letter they are forming their own lust and vengefulness. While on the Scaffold she looks down to see her missing husband Rodger Chillingworth and he is horrified and ashamed. It is hard to forgive and Chillingworth mentally vows revenge to the one who impregnated his wife. He later tells her not to let his identity to be known. Even in chapter four The Interview it is hard for us to see the path of evil he is about to follow.

Critical Analysis of the Methodology Used by Barba-Briosco et al. in Their Study of Pollutants in the Huelva Estuary, Spain

Introduction This paper provides a critical analysis of the methodology used by Barba-Brioso et al. (2010) in their study about water pollution from multiple sources in the Huelva Estuary, Spain. It discusses the extent to which this methodology has enabled the authors to achieve their aims and objectives, focusing on whether one could be confident with the quality of the data provided. It also tackles whether there are any areas in which the methodology could be improved. Barba-Brioso et al. (2010) studied major ions, nutrients, pesticides, etc. in human development-impacted coastal wetland of Huelva Estuary. The hydrodynamics of the area has been modified by previous land use, which led to the division of the ecosystem into a tideland and an artificial freshwater basin. The Huelva Estuary, which is polluted by mine, causes the flooding of the tideland stretch, which occurs twice a day. Acid discharges are also collected in the tidal channel from industrial point sources that play a part in metal enhancement. The tidal situation in Huelva Estuary has an important contribution to the transport of pollutants except for the artificial basin exhibiting cyclic mineralisation pattern. Barba-Brioso et al.’s Methodology The authors initially adopted sampling of the tideland zone in order to take into account the impacts of tidal regimes, in which nine samples were taken for high tide and twelve for low tide. A Zodiac boat was used to access the sampling site. The cyclic freshwater variations were examined by taking water samples of 1-20 cm in lacustrine zone whereby five were collected during winter and three during summer. Additionally, the study collected three samples of running water in summer and five in winter which were taken from open pipes and tributary streams. Field constraints caused an imbalance to the sampling design. The methodology also adopted several specific studies for the reference of general procedures in taking the water samples, which is considered the strength of the methodology since it sought evidence-based practice to utilising the selected procedure. Ion chromatography was also used to determine sulfate, nitrate, and bromide concentrations, amongst others. Critical Analysis of the Methodology The measurement used in Barba-Brioso et al.’s study is rather intricate and highly systematic, as the research itself is objective, quantitative, and is assumed to be statistically valid, as quantitative research must be (Bamberger, 2000; Bower, 2005). The methodology is able to address the primary objective of ascertaining how the concentration of pollutants is influenced by tidal and cyclical regimes in Huelva Estuary. This is demonstrated in the manner by which sampling was chosen, specifically the 9 samples for high tide and twelve for low tide, so that the impacts of tidal regime may be considered. The same was done for the cyclical regimes, in which the same sampling pattern for water was collected. This paved the way to addressing the research objective being mentioned. The adoption of intricate methods for the data in Barba-Brioso et al.’s (2010) study is similar in extent as other studies citing it, such as Zhang et al. (2011) and Guillen et al. (2012). The adoption of the experimental method in Barba-Brioso et al.’s study to examine the research problem is harmonious with its use of basic descriptive statistics of element concentrations and other elements in the wetland. The use of Merck 1000 ppm and bicarbonate determination indicate its pursuit for accurate generation of results relating to water and wastewater examination. The objectivity of the study is also shown in its triplicate measurement of the samples, with the representative value (mean) having achieved specific percentage accuracy. Barba- Brioso and colleagues also cited other authors in their calculation of the instrumental detection limit, which is suggestive of their stance to provide evidence to the relevance and applicability of the method to their study. It only means that the authors wanted to back up their use of such method through other studies utilising the same. Moreover, the objective of detecting anthropogenic inputs through hydrochemical irregularities was addressed in the study by tackling hydrochemical parameters, amongst others, in basic descriptive statistics organised based on tidal and cyclical conditions that took place at the time when sampling was carried out. This allowed the analysis of the estuarine waters to find slight alkaline content alongside local recording of acidic values at the rim of the tidal channel during low tide periods. The objective of detecting anthropogenic inputs through hydrochemical irregularities was also addressed by an identification of the wide variation in the mean pH values in the lacustrine wetland, which is higher during winter (8.4) than during summer (7.5). In addition, the methodology used a Piper diagram to plot the hydrochemical data, bearing dissolved prime cations and anions, which then exhibited two major water types in the wetland, specifically sodium chloride sulfate and a mixture of cal cium, magnesium, and sulfate-chloride. The Piper diagram has been used also in other studies depicting similar direction as that of this study, such as in the studies of Adams et al. (2001), Cloutier et al. (2008), and Van den Boogaart and Tolosana-Delgado (2008). The procedure in Barba-Brioso et al. (2010) revealed greater concentrations of nitrate distribution during low tide, which increases in the upstream route as well as detected the highest levels of nitrate and phosphate in small streams. It may thus be inferred that these data emanating from the methodology, enabled Barba- Brioso et al. to address the second objective, which again is to detect anthropogenic inputs through hydrochemical irregularities. Such objective was also addressed by the methodology’s stance to determine Ca and Mg concentrations through atomic absorption spectroscopy as well as atomic emission spectroscopy to determine K and NA. The application of SPE and HPLC procedures in quantifying all the studied pesticides was also congruent with the objective of identifying the various sources of pollution by apportionment procedures. In the same manner, the methods being carried out alongside this (e.g. use of water and methanol to condition the cartridge, etc.) app arently supported the study’s intention to tackle the objective of identifying anthropogenic inputs through hydrochemical irregularities. Furthermore, to determine trace elements, the methodology used measurements of iron elevated contents at the convergence of the Tinto River and the Tidal channel. Citing the methodology In the study of Guillen et al. (2012), the authors did not use the same methods as Barba-Brioso et al. (2010) in their (Guillen et al., 2012) attempt to find out trace elements’ mobility through the modified BCR sequential extraction method. Rather, atomic absorption spectroscopy and atomic emission spectroscopy were utilised by Barba- Brioso et al. (2010). Mass spectroscopy with plasma of inductive couple carried out the analyses of dissolved trace elements in Barba- Brioso and colleagues’ study. The pursuit of the method to derive the expected precision was seen in an attempt to correct for any drift during the analysis through the measurement of certified reference material, thereby producing the range of a specific mean precision for all the analyses and a particular detection limit optimisation for all the trace elements being analysed.The apportionment methods also allowed different potentially toxic elements to be distributed on a closely parallel manner with the pattern of major cations and anions, in which a declining upstream trend was depicted during both high and low tides. The method used enabled the study to determine the sources of pollution in the Domingo Rubio wetland in Tideland area and overall wetland. The manner of data collection was highly scientific and accuracy-specific, as the study intended to investigate the major ions and trace elements as well as the pesticide distribution in the coastal wetland. The passing of the replicates of water sample through the equivalent cartridges at a specific flow rate was also indicative of an aim to ascertain pesticide distribution, which was linked to an objective of identifying the various sources of pollution in Domingo Rubio. It may also be observed that the analytical methods concerning anions and nutrients in which Merck 1000 ppm and Standard Methods were used to examine water and wastewater were parallel to the objectives of determining hydrochemical anomalies and various sources of pollution in the wetland. It may therefore be claimed that the extent to which the methodology has enabled the investigators to meet the stated aims and objectives is sufficient enough. Further, the quality of the data being provided was something to be confident about. The authors enumerated the analytical methods and procedures one by one, strongly focusing on the details of these procedures, including the elements being examined. They also used a table on which to organise the data, clear enough for the reader to understand them. The high confidence level of the data being presented is indicative of how they were analysed in the results section, in which the parameters of water quality were summarised and compared, alongside the samples’ chemical composition. In this regard, the study is able to pinpoint that the tidal channel is characterised by slight alkaline content, describing its pH mean values during low tide and high tide, and that there is the presence of acidic values at the rim of the tidal channel during low tide. This specific analysis was enabled by the kind of data being gathered and the manner through which to analyse them. In addition, the methodology paved the way for the result to conclude that the water samples being examined were oxidising. Similarly, it was able to point out that the most acidic water had the higher Eh values, leading to a deviation from the common pattern demonstrated by the dominant waters in the wetland. The results also revealed the existence of the effect of tidal interaction through the way the data were used to examine the gradual decline of the electrical conductivity in the upstream route. The data also allowed identifying the period when the maximum value was recorded. The study’s depiction of dissolved oxygen concentrations in the draining streams across the agricultural areas is parallel to its objective to find out the influence of tidal and cyclical conditions on the concentrations of pollutants. An interesting point to mention is the fact that Barba-Brioso et al.’s (2010) study was cited by Haarstad et al. (2011) in their investigation of pollutants in natural wetla nds and the latter also used the experimental design, enabling the authors to identify the pesticides found and identify toxic heavy metals. An experimental design – with a different statistical approach – was also utilised in Barba-Brioso et al.’s (2010) study on the application of the life cycle impact assessment to the Domingo Rubio tidal structure. With the above discussion, it is thereby concluded that there are no more areas in which the methodology could be improved as it was able to cover all the necessary aspects deemed to be achieved by the objectives. Conclusion This paper has been focused on analysing critically the methodology adopted in the study of Barba-Brioso et al. (2010), which is about water pollution from multiple sources in the Huelva Estuary. This work is able to pinpoint the extent to which the methodology has allowed the aims and objectives to be addressed in their entirety. Sampling for both high tide and low tide was utilised in Barba-Brioso et al.’s study to consider the impacts of tidal regimes, in which water samples were taken during winter and summer. A highly systematic and intricate methodology was adopted, considering that the study itself was quantitative where objectivity and statistical validity were highly considered. The study’s adoption of the experimental method is consistent with the use of basic descriptive statistics that allowed examining the concentrations of elements in the wetland. It also utilised hydrochemical parameters, amongst others, as a way to contribute to addressing its objective to identify hydrochemical irregularities. With the study’s identification of dissolved oxygen concentrations in the draining streams, it likewise tackled the objective of recognising the influence of tidal and cyclical conditions on the concentrations of pollutants. The conclusion thus generated is that the methodology was able to cover all areas and that there were none left to be improved because of this.
