Transcripts
if you work with computers you've likely
heard terms like ram hard drive and
processor mentioned by tech support or
others who are more interested in what
goes on inside of a computer's case
if you've always wondered what the
various components of your computer are
for but have never really had the time
to look into it then this video is just
for you while each one of these
components is complex enough to spend a
lifetime learning about i'm gonna give a
very broad and general overview
a typical desktop computer comes down to
these seven essential parts
case power supply motherboard cpu
ram hard drive and graphics cards
these are the fundamental parts of any
desktop computer it may seem daunting at
first so let's separate these into two
categories
simple ones and the more complex ones
for starters let's look at the case
the case is nothing more than a big hunk
of plastic that houses everything else
some of them have more or less physical
space some of them have different parts
where you can put screws in or this or
that but at the end of the day all the
case really does is provide a nice
enclosed system for everything else
next up we have the power supply this
part of your computer almost always
located on the bottom is the part that
plugs into the wall and provides all of
the other parts with the electricity
needed to do their thing
you can think of it as an extremely
advanced ac adapter
the last of the simple parts to mention
is the motherboard the motherboard is a
wide and flat circuit board that all of
the other components plug into it's the
part that lets all of these components
send electrical currents composing data
between each other
while not particularly expensive the
motherboard is arguably the most
important component because without it
you'd have nowhere to put anything else
so that's it for the simple components
now let's move on to the more complex
parts the ones that deal with data
the four main components to keep in mind
here are cpu ram hard drive and graphics
card
now first things first i'm going to
establish some terminology
keep in mind that cpu is also known as
the central processing unit or processor
these terms all refer to the same thing
they are completely interchangeable
ram stands for random access memory and
is often referred to as just memory a
hard drive is often referred to as a
disk drive or storage
and a graphics card is also known as a
gpu or graphics processing unit
for this explanation i'll be using the
terms cpu ram hard drive and graphics
card
so let's start with the cpu the cpu is
where your computer does things it isn't
really capable of storing very much data
at all but it's very good at doing
things with data quickly reading it
arranging it doing the type of quick and
massive calculations needed to run your
programs
this is where most of your programs are
essentially run from
it's often referred to as the brain of
the computer i personally don't like
this description because really your
entire computer is just a brain it's
just the center part of your computer's
brain basically everything that happens
in your computer goes through your cpu
at some point
now let's talk about ram and hard drive
at the same time because they have a
very unique relationship which is
probably why people often confuse the
two
your hard drive is where all of your
data is stored when your computer tells
you you're running low on space it's
because your hard drive is almost full
all of the data that makes up your
videos pictures documents project files
or the 3d worlds and models that make up
a game are all stored here
while hard drives can store lots of data
they're relatively bad at accessing that
data quickly
everything is accessed through a tiny
little wire here and because most hard
drives are made up of spinning disks
your hard drive isn't going to be able
to constantly give your cpu the
information it needs to run certain
programs that's where ram comes in
ram is another form of storage it stores
the exact same kind of data as your hard
drive but ram sacrifices storage space
for nearly instant accessibility
unlike your hard drive which sends all
of its data through a tiny little thin
wire your ram is arranged in these long
thin sticks that insert into your
motherboard think about a storage unit
if you have a massive warehouse with
only a thin doorway it's going to be
difficult to get in find what you need
and get out if it's kind of spread all
over the place you'll have to go through
a tiny door
but if you have a long wide storage shed
that's got a big massive garage
composing an entire side of it you won't
be able to store as much but things are
significantly easier to get to typically
if your computer has a thousand
gigabytes of storage space in your hard
drive it's likely got about 16 gigabytes
worth of ram here's where you put the
stuff you own but you aren't currently
using and this smaller one is where you
put the stuff that you are using and
need to be able to get in and out of
quickly
when you run a program or a project file
your cpu identifies what parts of data
are needed for that program to run
it pulls them from your hard drive and
then it stores them in your ram sticks
for quick accessibility this is why when
you start a new level of a game for
instance it has to load anytime you see
loading it's loading the data that
composes that level from your bulky hard
drive into your ram from a user's
perspective just follow this rule of
thumb
ram allows you to run intensive programs
while disk space allows you to have more
of these in programs installed
it also allows you to have more of the
data they're referencing whether it be
pictures videos or mods
and finally we get to the graphics card
with all of the calculations going on in
your computer to turn a bunch of numbers
that basically come down to ones and
zeros into a constantly updated
three-dimensional world
the final and most important and
arguably most difficult step is to
display that on your monitor
it's possible for your motherboard to do
this alone but it's not going to look
good and it's certainly not going to be
able to do much
your graphics card is essentially an
entire computer in and of itself
dedicated to the sole task of figuring
out what pixels need to light up on your
screen in what color and at what time if
you were playing a game that had a very
busy and high texture world with lots of
models and different angles and colors
your cpu is the thing that creates that
world it knows where the stuff is and it
does so with data that's been stored in
your ram which was loaded out of your
hard drive but it's your graphics card
that figures out what it's supposed to
look like based on where you're standing
in the world without getting too off
topic here if you're somebody who likes
math i highly recommend you look up fast
inverse square root which is directly
related to how three-dimensional worlds
calculate perspectives
so that pretty much sums it up there are
other components worth mentioning such
as cooling systems or internal wireless
cards but really those are extras
so to summarize what i talked about so
far the case stores everything in a
physical box the power supply gives
electricity to what needs it the
motherboard is the body that everything
plugs into the cpu does everything
ram stores data that is needed for quick
access
hard drives store everything that you
have installed and the data that goes
along with those programs
well the graphics card figures out how
it's all supposed to look on your
monitor well thank you very much for
watching i hope i helped and if you have
any questions feel free to leave a
comment and i'll do my best to answer
them liking and subscribing is always a
big help and i plan to put out many more
videos explaining technical concepts
such as this one
