RESETTING CMOS PASWORD

1. Power down your computer:Turn off the computer and any attached devices, such as printers, monitors, and external drives. Unplug all power cords from electrical outlets, and remove the cover. 2. Open the case and Locate CMOS Battery:Open the case of CPU and Locate the CMOS battery. The CMOS battery is round and silver, much like a watch battery. Carefully remove it from its housing. Wait for 5-10 minutes so that all of the power stored in the capacitors on the motherboard can discharge.

3. Replace the battery: All of the BIOS settings will be reset the next time that you turn the computer on. You will need to reset the time and date in the BIOS setup menu.

4. Set Date and Time:Now from the BIOS you can set Date and Time easily. After setting date and time you are good to go.

TYPES OF PRINTER:According to the author Peter Norton there are four types of printer:

1. Dot matrix printer2. Inkjet printer3. Laser printer

1. DOT MATRIX PRINTER:Dot matrix printers are commonly used in workplaces where physical impact with paper is important, such as when the user is printing to carbon copy or pressure sensitive forms, these printers can produce sheets of plain text quickly. They are also used to point very wide sheets, as data processing departments often use when generating large reports with wide columns of information. The lowest resolution dot matrix printers have only nine pins; the highest resolution printers have 24 pins. The slowest dot matrix printers create 50 to 70 characters per second; the fastest print more than 500 cps.

2. INJ JET PRINTERS:Ink jet printers create an image directly on the paper by spraying ink through tiny nozzles, the popularity of ink jet printers jumped around 1990 when speed and quality improved and prices plummeted, today, good ink jet printers are available for less than $100. These models typically attain print resolutions of at least 300 dots per minute.Color ink jet printers have four ink nozzles: cyan, magenta, yellow and black. For this reason, they are sometimes referred to as CMYK printers, or as using the CMY color process. These four colors are used in all most all color printing because it is possible to combine them to create any color.

3. LASER PRINTERS:Laser printers are more expensive than ink jet printers, their print quality is higher, and most are faster, as their name implies. Just as the electron gun in a monitor can target pixel, the laser in a laser printer can aim at any point on a drum, creating an electrical charge, toner, which is composed of tiny particles of ink, stick to the drum in the places the laser has been charged =, then, with pressure and heat, the toner is transferred off the drum onto paper. The amount of memory that laser printers contain determines the speed at which documents are printed.A color laser printer works like a single-color model, except that the process is repeated four times and a different toner color is used for each pass. The four color used are same as in the color ink jet printer.Single color laser printers typically can produce between 4 and 16 pages of text a minute. If you are printing graphics, the output can be a great deal slower. The most common laser printer have resolution of 300 or 600 dpi, both horizontally and vertically, but some high-end models have resolution of 1200 or 1800 dpi. Its difficult to detect the difference between text printed at 600 dpi and at 1200 dpi; the higher resolution is most noticeable in graphics reproduction such as photographs and art work.
