Switched-mode power supply:-
A switched-mode power supply
is an electronic power supply that incorporates a switching regulator to
convert electrical power efficiently. Like other power supplies, an SMPS
transfers power from a DC or AC source to DC loads, such as a personal computer,
while converting voltage and current characteristics
MOTHER BOARD:-
A motherboard is the main printed circuit board found in general purpose computers and other expandable systems. It holds, and allows, communication between many of the crucial electronic components of a system, such as the central processing unit and memory, and provides connectors for other peripherals.
HARDDISK:-
A hard disk drive (HDD), hard
disk, hard drive, or fixed disk] is an electro-mechanical data storage device that uses magnetic storage to store and retrieve digital data using
one or more rigid rapidly rotating platters coated with magnetic material. The platters are
paired with magnetic heads, usually arranged on a moving actuator arm,
which read and write data to the platter surfaces. Data is accessed in
a random-access manner,
meaning that individual blocks of data can be stored and retrieved in any
order. HDDs are a type of non-volatile storage, retaining stored data even when powered off.

PROCESSOR
Central processing unit
A central processing
unit, also called a central processor or main processor, is the electronic
circuitry within a computer that executes instructions that make up a computer
program. The CPU performs basic arithmetic, logic, controlling, and
input/output operations specified by the instructions in the program.
RAM
Random-access memory is
a form of computer memory that can be read and changed in any order, typically
used to store working data and machine code. A random-access memory device
allows data items to be read or written in almost the same amount of time
irrespective of the physical location of data inside the memory.
DVD DRIVE
In computing, an optical disc drive (ODD) is a disc 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 certain discs, but recent drives can both read and record, also called burners or writers (since they physically burn the organic dye on write-once CD-R, DVD-R and BD-R discs). Compact discs, DVDs, and Blu-ray discs are common types of optical media which can be read and recorded by such drives. Optical disc drives that are no longer in production include CD-ROM drive, CD writer drive, combo (CD-RW/DVD-ROM) drive, and DVD writer drive supporting certain recordable and rewritable DVD formats (such as DVD-R(W) only, DVD+R(W) only, DVD-RAM only, and all DVD formats except DVD-R DL). As of 2015, DVD writer drive supporting all existing recordable and rewritable DVD and CD formats is the most common for desktop PCs and laptops. There are also the DVD-ROM drive (used on DVD players and some game consoles), BD-ROM drive (Used on Blu-ray players and some game consoles), Blu-ray Disc combo (BD-ROM/DVD±RW/CD-RW) drive, and Blu-ray Disc writer drive.
