2. ATX Casing

3. What is an ATX pc case?
ATX is a form factor for desktop computer cases,
motherboards, and power supplies. ATX cases come
in differing sizes, but they all are large enough to
have a motherboard, at least one video card, and
other hardware installed inside. Most ATX cases are
able to hold several hard drives, both 2.5 inch and
3.5 inch, as well as at least one 5.25 inch optical
drive. Other common features are 3.5 external
drive bays, usable for installing hot swappable
3.5inch or 2.5inch drive bays and floppy disk
drives, as well as other peripherals.

4. What is an ATX pc case?
An ATX computer case is a PC case that complies to
the ATX (Advanced Technology Extended) computer
tower specifications. This standard was introduced
by Intel in 1995 and defines acceptable sizes for
motherboards, desktop computer cases, and
computer power supplies. Most computer cases fall
into the ATX specification, which guarantees that
other computer components will be compatible
with the ATX computer case you purchase. You'll
find that most (if not all) ATX cases are compatible
with Micro ATX motherboards as well.

5. Motherboard / MOBO

6. What is the main function of motherboard?
* The motherboard serves as a single platform to
connect all of the parts of a computer together.
It connects the CPU, memory, hard drives, optical
drives, video card, sound card, and other ports and
expansion cards directly or via cables.
* A motherboard is the main printed circuit board 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.

8. Microprocessor / Processor

9. Microprocessor / Processor
A microprocessor is a computer processor
where the data processing logic and control
is included on a single integrated circuit, or a
small number of integrated circuits. The
microprocessor contains the arithmetic,
logic, and control circuitry required to
perform the functions of a computer's
central processing unit.

10. RAM Random Access Memory

11. RAM Random Access Memory /
Memory Modules
A memory module or RAM stick is a printed circuit
board on which memory integrated circuits are
mounted. Memory modules permit easy installation
and replacement in electronic systems, especially
computers such as personal computers, workstations,
and servers.

12. Storage Devices
HDD, SSD, M.2 NVME

13. Storage Devices
HDD Hard Disk Drive - A hard disk drive (HDD), hard
disk, hard drive, or fixed disk is an electro mechanical
data storage device that stores and retrieves digital
data using magnetic storage and one or more rigid rapidly
rotating platters coated with magnetic material.
SSD Solid State Disk - A solid-state drive is a solid-state
storage device that uses integrated circuit assemblies to store
data persistently, typically using flash memory, and functioning
as secondary storage in the hierarchy of computer storage.

14. M.2 SSD- is a small form factor solid-state drive (SSD)
that is used in internally mounted storage expansion
cards. M.2 SSDs conform to a computer industry
specification and are designed to enable high-
performance storage in thin, power-constrained
devices, such as ultrabook laptops and tablet
computers. They are generally smaller than other
comparable SSDs, such as the mini Serial Advanced
Technology Attachment (mSATA).

15. Graphics Processing Unit /
Video Card

16. Graphics Processing Unit (GPU) is a chip or
electronic circuit capable of rendering graphics
for display on an electronic device. The GPU was
introduced to the wider market in 1999 and is best
known for its use in providing the smooth graphics
that consumers expect in modern videos and games.

17. ATX Power Supply

18. ATX Power Supply - A power supply unit (PSU)
converts mains AC to low-voltage regulated
DC power for the internal components of a
computer. Modern personal computers universally
use switched-mode power supplies. Some power
supplies have a manual switch for selecting input
voltage, while others automatically adapt to the
mains voltage.
