Apart from that, that main circuit board also had the Read Only Memory subsystem (ROM), the IRQ and DMA controllers, sound circuitry, coprocessor sockets and keyboard interface attached. The sound circuitry included the PC speaker or tone generation unit. That is how the name “motherboard” and everything involving it, all began. In any computer organization motherboard is the primary component. It incorporates all the fundamental units required for a computer. The Main components of a motherboard are Thus we see that a motherboard holds most of the primary logic required for a computer and thus justifies its name to adapt a computer to use widely different types of secondary devices, like – the floppy drive, the hard disk, the display adapter, the printer....

SMPS also uses a switching regulator to convert electric power efficiently. The computer power supply changes A.C. (Alternating Current) to low voltage D.C. (Direct Current) to run peripheral devices. Nowadays computer uses SMPS as a primary power supply. Computer’s PSU is generally smaller and lighter as compared to a linear supply because of smaller transformer size and weight. Mainly, SMPS switches elements includes, inductors, capacitors, transformer and all the different kinds of electrical components to regulate the output voltage and current....
