Weak current College】 【BIOS and CMOS of similarity and difference.

<br> BIOS? <br> <br> BIOS is (BasicInput / OutputSystem, basic input / output system abbreviation) in a computer to the most basic and most important role. Is the computer in the most basic and most important programs. Put .this program in one does not need to supply memory (chip), which is usually referred to by the BIOS. <br> <br> It is a computer with the bottom, the most direct hardware control, your computer's original operations are in accordance .with curing the contents of the BIOS. Specifically, the BIOS is hardware and the software procedures between an interface or a converter, is responsible for addressing the immediate needs of the hardware and software requirements for hardware implementation of the action. Computer users in the process .of using the computer, access to the BIOS in the computer system plays a very important role. <br> <br> What is CMOS? <br> <br> CMOS, namely: ComplementaryMetalOxideSemiconductor - complementary metal oxide semiconductor (purported means complementary metal .oxide semiconductor storage the lodge, is a large-scale application in integrated circuit chip manufacturing of raw materials), is a computer motherboard readable and writable RAM chip, mainly used to save the current system's hardware configuration and operations staff on the setting of certain parameters .. CMOSRAM chip from the system through a back-up battery, it is in a shutdown state, or in the event of system power down, CMOS information will not be lost. <br> <br> BIOS and CMOS of difference and relationship: .<br> <br> BIOS is a group of settings for the hardware of the computer program, save on the motherboard of a EPROM or EEPROM chips, which is equipped with a system of important information and settings of the Setup program of system parameters - .BIOSSetup program. The CMOS: ComplementaryMetalOxideSemiconductor - complementary metal oxide semiconductor, is on the Board a readable and writable RAM chip, used to save the current system's hardware configuration and parameter setting of the user, the content available through the Setup program for reading and writing .. CMOS chip from the motherboard battery power, even if the system is powered down, the parameters will not be lost. CMOS chip only saved data, and the various parameters in CMOS changes to the BIOS Setup program. <br> <br> BIOS .and CMOS is both relevant and different: the BIOS system setup program is completed CMOS parameter settings; CMOSRAM is both a BIOS setting system parameters of storage places, and a BIOS setting system parameters. Therefore, the complete argument should be "through the BIOS Setup .to set "CMOS parameter. Since the BIOS and CMOS are beginning with system settings and dense, so in practice associated with the process resulted in the BIOS settings and CMOS settings, actually refers to is the same thing, but the BIOS and CMOS are two .completely different concepts, not to confuse. <br>.
