The correct answer is Motherboard.The software and hardware of a computer get instructions for processing a task that is generated or produced by a complex and heavy set of electronics devices that are embedded on a platform which is known as a motherboard.The motherboard allows communication to and between the CPU, RAM, and all other computer hardware components.A motherboard (also called mainboard, main circuit board, system board, baseboard, planar board, logic board, or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems.It holds and allows communication between many crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Additional InformationHDD:-A hard disk drive (sometimes abbreviated as a hard drive, HD, or >HDD) is a non-volatile storage device.It is usually installed internally in a computer, attached directly to the disk controller of the computer's motherboard.SMPS:-SMPS or switched-mode power supply is an electronic device that is used to convert AC to DC, AC to AC, DC to DC, and DC to AC voltages. RAM:-It is called 'volatile' memory by analogy because if the computer loses power, all the data stored in RAM (or other volatile memory) is lost or 'evaporates'.
