Cmos

 It looks like you meant CMOS instead of "comos."


CMOS (Complementary Metal-Oxide-Semiconductor) in a Motherboard


CMOS is a small amount of memory on a motherboard that stores BIOS (Basic Input/Output System) settings, such as:


System time and date


Boot order


Hardware configurations


Passwords and security settings



CMOS Battery


A small coin-cell battery (usually CR2032) powers CMOS to retain these settings even when the computer is turned off. If the battery dies, settings reset to default, and you may experience boot issues or incorrect system time.


Would you like help troubleshooting a CMOS-related issue?

                    Bios setup It is a plate form which is provide to make trigger of our system. all the hardware device attatch to our system we can enable& disable the work all these divice's & up ,&down the performance of these divice's when we go to in BIOS setup mostly we founde all these option, which is use to increase or decrease performance all attached hardware devices.so these option show in below manner. standard cmos setup- Enable the user to set basic information such as data time , IDE device disk drive. Advance setup- Sets advanced Information such as boot device  ' smart for harddisk boot up numlock, floppy drive swap about the system. power management system- Sets the parameters such as stand by time out , ring on power on for the system power management operation. PcI plug & play setup- Sets the parameters for the device installed on the pic bus & device which use the system plug & pl...

 The first electronic printer was the EP-101, invented by the Japanese company Epson and released in 1968.  so it was debuted in the market, The first commercial printers typically used mechanisms from electric typewriters and teletype machines. INTRODUCTION- The printer is an device that prints text document & image on paper. it is peripheral output device. IMPACT PRINTER- Printers are used for printing document  as well as graphics. the working of impact printer is very similer to that type of printer. lmpact printer are those printer, where physical contact is established between print head , cartridge&  media paper . the impact result in printing on paper under the ink ribbon. the dot matrix printer is an example of impact printer. DOT MATRIX PRINTER- Dot matrix printer uses a matrix of metal pins on the electromagnet printhead to creat dots & ink  soaked ribbon is placed between the paper & the print head . due to this dot matrix printer are...

 S.M.P.S-It mostly found the left corner in the system&It convert (a.c) to (dc) power supply. in system  different type of components that's requirement different type normal that 3.3v, 5v, 15v. Microprocessor take3.3v, chipset 5v, harddisk take 12v.current. Give output different controller- (-12 v) blue wire- Require for serial port. (-5 v) White wire- Require for older floppy                                     controller, I.S.A.card. 0 volt( black)- Require for complete circuit. 3.3 volt ( orange)- require for dim , pci, agp card . 5 volt( Red) - Require for sim , disk drive. 12 volt ( Yellow) - Require cooling for fan. pg signal ( gray)- Mother board indication power on ( green)- controll to power supply. Type of power supply-  Linear power supply-  switch mode power supply-  Linear- Diode circuit is used to rectify ac to pulsating Dc . After than capictor used to p...
