What role does the motherboard play in a computer?
-The motherboard is the main board inside the computer case where all other cards and components plug directly into, serving as the central hub for connecting all the parts.
How is the CPU described in the script?
-The CPU is likened to the brain of computer systems, taking processes from the RAM and processing them to perform tasks required by the computer system.
What is the purpose of RAM in a computer system?
-RAM provides fast read and write access for data storage and keeps data ready for the CPU to process. It is volatile, meaning it loses data when power is lost.
What does a graphics card do and how is it connected to a display?
-A graphics card processes data from the motherboard and sends information to the computer screen for display. It can be connected to monitors using HDMI, DisplayPort, DVI, or VGA connectors.
Why might someone use a sound card instead of the built-in sound chip on the motherboard?
-Sound enthusiasts or those who prefer high-quality audio output while gaming might use a sound card for better audio performance.
What is the main function of a hard disk drive (HDD)?
-An HDD is used to store information for retrieval at any time and also functions as a boot drive to run the operating system.
How does an SSD differ from a traditional HDD?
-An SSD is a type of hard drive without moving parts, consisting of flash memory to hold information, offering faster access speeds compared to HDDs.
What is the purpose of the power supply unit (PSU) in a computer?
-The PSU converts AC power from the wall socket to the correct DC voltages needed to supply power to all the components inside the computer.
What is the function of a monitor in a computer system?
-A monitor is an output device used to visualize graphics information sent from the computer's GPU.
How do input devices like the keyboard and mouse interact with a computer system?
-Input devices like the keyboard and mouse allow users to communicate with and interact with the computer system more intuitively.
What are some common peripheral parts for computers mentioned in the script?
-Common peripheral parts include printers, scanners, and speakers, which are used for outputting images, scanning documents, and audio output respectively.

💻 Basic Computer Components
This paragraph introduces the fundamental parts of a computer and their functions. The computer case, or system unit, houses all the components. The motherboard serves as the main board where other components plug in. The CPU acts as the brain of the computer, processing tasks. RAM is volatile memory that stores data for quick CPU access. The GPU processes data for display on a screen. Sound cards are used for enhanced audio output. Hard Disk Drives (HDD) and Solid-State Drives (SSD) are storage devices, with HDD being mechanical and SSD being non-mechanical. The PSU converts AC power to DC for components. Monitors display graphics, while keyboards and mice are input devices. Peripherals like printers, scanners, and speakers complete the computer system.

the basic parts of a computer and their
functions knowing what the computer
parts are is good but we will explain
each part's function giving you a firmer
understanding of them one the computer
case or system unit this is the
component that holds all of the parts to
make up the computer system cases come
in all different sizes and shapes to
accommodate various types of computer
components and satisfy the consumer's
needs 2. the motherboard the motherboard
is the main board that is screwed
directly inside the computer case all
other cards and everything else plugs
directly into the motherboard hence its
name three Central Processing Unit or
CPU the CPU or Central Processing Unit
is basically like the brain of computer
systems it takes all the processes from
the RAM and processes them to perform
the tasks required by the computer
system 4. random access memory or ram
ram is a data storage device that can
provide fast read and write access Ram
is volatile memory meaning it loses all
the stored data when power is lost the
ram keeps data ready for the CPU to
process
5. the graphics card otherwise known as
the graphics Processing Unit or GPU a
graphics card is an output device that
processes the data from the motherboard
and sends the appropriate information to
the computer screen for display you can
connect monitors to it using HDMI
DisplayPort DVI or VGA connectors
6. a sound card most of the time the
sound chip built into the motherboard is
used for audio output but if you are a
sound Enthusiast or prefer high quality
audio output while playing a game you
might be inclined to use a sound card 7.
the hard disk drive or HDD a hard drive
is still found in many PCs to this day a
mechanical drive's purpose is to store
all your information for retrieval at
any time apart from storing information
for your computer it also functions as a
boot drive to run the operating system
or Os from it 8. the solid-state drive
or SSD an SSD is also a type of hard
drive but it doesn't have any moving
bits it consists of a bank of flash
memory that can hold a reasonable amount
of information
9. the power supply unit or PSU a power
supply unit mounts inside the computer
case it converts the AC main Supply from
the power cord from a wall socket and
supplies the correct DC voltages to all
the components 10. a monitor sometimes
referred to as the visual display unit
or vdu a monitor is an output device
used to visualize the graphics
information sent from the computer's GPU
11. the keyboard a keyboard is an input
device that is one of the ways to
communicate with a computer
12. the mouse
a mouse is an input device that allows
the user to move a pointer displayed on
the Monitor and experience a more
intuitive interaction with computer
systems common peripheral parts for
computers a printer a printer can take
an image sent by a computer and deliver
it onto a sheet of paper a scanner a
scanner can take anything on paper and
it functions by scanning it to produce a
replicated digital image for a computer
to save computer speakers
speakers can connect to the sound card
at the rear of the computer another way
they can be connected is by a monitor
that already has built-in speakers that
covers all the components of a computer
system thanks for watching you can read
