2. 1
Introduction
A computer is a complex system made
up of various components working
together to perform tasks efficiently.
Understanding the role of each part is
crucial for optimizing a computer's
performance.
This presentation will delve into the
key components that make up a
computer and their functions.

3. 2
Motherboard
The motherboard is the main circuit
board that houses the CPU, RAM, and
connects all other components.
It acts as a communication hub,
allowing data to flow between
different parts of the computer.
The motherboard plays a vital role in
determining the overall performance
and compatibility of the system.

4. 3
Central Processing Unit (CPU)
The CPU is the brain of the computer,
responsible for executing instructions
and performing calculations.
It determines the speed and
processing power of the system.
The CPU's performance is measured
in terms of clock speed and the
number of cores it has.

5. 4
Random Access Memory (RAM)
RAM is a type of memory that
temporarily stores data and
instructions that the CPU needs to
access quickly.
It allows for faster data retrieval
compared to storage devices like hard
drives.
The amount of RAM in a computer
directly impacts its multitasking
capabilities and overall performance.

6. 5
Storage Devices
Storage devices, such as hard drives
and solid-state drives, are used to
store data and programs permanently.
Hard drives offer high storage
capacity at a lower cost, while SSDs
provide faster read/write speeds.
The choice of storage device affects
the system's boot times, file access
speeds, and overall responsiveness.

7. 6
Graphics Processing Unit (GPU)
The GPU is responsible for rendering
images and videos on the computer's
display.
It is essential for tasks like gaming,
video editing, and graphic design.
GPUs with dedicated memory
enhance visual performance and
support complex graphical
calculations.

8. 7
Power Supply Unit (PSU)
The PSU converts AC power from the
outlet into DC power that the
computer's components can use.
It supplies power to all parts of the
computer, ensuring proper
functioning.
Choosing a PSU with sufficient
wattage and efficiency is crucial for
system stability and longevity.

9. 8
Cooling System
Cooling systems, including fans, heat
sinks, and liquid cooling solutions,
prevent components from
overheating.
Proper cooling is essential for
maintaining the longevity and
performance of the CPU and GPU.
Overheating can lead to thermal
throttling and system instability.

10. 9
Input and Output Devices
Input devices like keyboards and mice
allow users to interact with the
computer.
Output devices, such as monitors and
printers, display information or
produce tangible results.
Choosing high-quality input and
output devices enhances user
experience and productivity.

11. 10
Networking Components
Networking components, like network
interface cards and routers, enable
computers to connect to the internet
and other devices.
Wired and wireless networking
technologies offer different levels of
speed and convenience.
A stable and secure network
connection is essential for online
activities and file sharing.

12. 11
Expansion Cards
Expansion cards, such as sound cards
and graphics cards, enhance the
computer's capabilities.
They can add features like improved
audio quality or additional display
outputs.
Compatibility with the motherboard's
expansion slots is crucial when
installing expansion cards.

13. 12
BIOS/UEFI
The Basic Input/Output System
(BIOS) or Unified Extensible
Firmware Interface (UEFI) initializes
hardware components during the boot
process.
It also provides low-level system
settings that users can configure.
Keeping the BIOS/UEFI up to date
ensures system stability and security.

14. 13
Operating System
The operating system (OS) is software
that manages hardware resources and
provides a user interface.
Popular OS options include Windows,
macOS, and Linux, each with its
features and compatibility.
The choice of OS impacts software
compatibility, security, and user
experience.

15. 14
Maintenance and Upgrades
Regular maintenance, such as
cleaning dust from components and
updating software, prolongs a
computer's lifespan.
Upgrading components like RAM,
storage, or the GPU can enhance
performance without buying a new
system.
Understanding when to upgrade and
how to do so properly is essential for
maximizing a computer's potential.

16. 15
Conclusion
A computer is a complex system with
various components that work
together to perform tasks efficiently.
Each part plays a specific role in the
computer's functioning, from the CPU
and motherboard to storage devices
and cooling systems.
Understanding these components and
their functions is key to optimizing a
computer's performance and
longevity.
