Optical disc drive
In computing, an optical disc drive(ODD) is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from discs, but recent drives are commonly both readers and recorders, also called burners or writers. Compact discs,DVDs , and Blu-ray discs are common types of optical media which can be read and recorded by such drives. Optical drive is the generic name; drives are usually described as "CD" "DVD", or "Blu-ray", followed by "drive", "writer", etc.
CPU(pronounced as separate letters) is the abbreviation for central processing unit.
A motherboard (sometimes alternatively known as the mainboard, system board, planar board or logic board,or colloquially, a mobo) is the main printed circuit board (PCB) found in computers and other expandable systems.
