How Bois Does The Work In Computer

The ROM BIOS chip on the motherboard contains the programming to start up the PC as well as perform many other fundamental tasks, The CMOS set up chip powered by a battery when the PC is turned off contains data about the system configuration as well as the current time and date, even though the computer has so many CMOS chips, the term "CMOS chips" has come to mean the one chip on the motherboard that holds the configuration or setup information stored on this one CMOS chip, the program to change the CMOS setup is stored in ROM BOIS chip and can be accessed during the starup process, A motherboard can also retain setup or installation information in different settings of jumpers or DIP switches on the board, JUMPERS are considered open or closed based on whether a jumper cover present on two small wires that stick up off motherboard,a group of jumpers is sometimes used to tell the system at what speed the system is running, or to turn a power saving feature on or off, A DIP (DUAL INLINE PACKAGE) switch is similar to a light switch and is on or off based on the direction in which the small switch is set , Most motherboards have at least one often several jumpers and perhaps a single bank of DIP switches, Although the trend is to include most setup information in CMOS rather than two have a jumper or switch on the board that has to be mechanically set,
Setup information about the motherboard can be stored by setting a jumper on (closed)or of (Open) a jumper is closed if the cover is in place,connecting the two wires that make up the jumper , a jumper is open if the cover is not in place.
