If you’ve always wondered what the various components of your computer are for but I’ve 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 going to give a very broad and general.
A typical desktop computer comes down to these 7 essential parts case power supply motherboard CPU ram hard drive,
and graphics cards are the fundamental parts of any desktop computer it may seem daunting at first,
so let’s separate these into 2 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 house is everything else some of them,
have more or less physical space some of them have different parts we can put screws,
and or this or that but at the end of the day all the case really does is provide a nice close system for everything else.

Extremely advanced AC adapter
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 is a wide,
and the flat circuit board that all the other components plug into it’s the part that lets all of these components,
and electrical currents composing data between each other well not particularly expensive the motherboard is arguable,
the most important component because without it you 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 4 main components to keep in mind,
here is the CPU ram hard drive and graphics cards now first things first I’m going to establish some terminology.
The central processing unit
Even mind that CPU is also known as the central processing unit or process these terms all refer to the same thing they’re completely interchangeable.
Ram stands for random access memory and is often referred to as just memory,
hard drive is often referred to as a disk drive or storage.
And a graphics card is also known as the 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 is where your computer does thanks 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’s arranging it’s doing that type of quake,
and massive calculations needed to run your program.
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,
the 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 are often confused.
Documents project files
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 of all the data that makes up your videos pictures documents project files,
or the 3 D. worlds and models that make up the 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 is 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.
Ram is another form of storage the store is the exact same kind of data as your hard drive,
but the 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.
The storage unit
Think about the storage unit if you have a massive warehouse with only a thin doorway,
it’s gonna be difficult to get and find what you need and get out if it’s kind of spread all over the place,
you want to go through a tiny door.
But if you have long and 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 typically.
If your computer has 1000 gigabytes of storage space on your hard drive it’s like,
we got about 16 gigabytes worth of brand here’s where you put the stuff you own,
but you are currently using and the 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 project file your CPU identifies what parts of data are needed for that program to run,
pulls them from your hard drive and it stores them in your ram sticks for quick accessibility.
The game for instance
This is why when you start a new level of the game for instance it has to look anytime you see loading,
it’s loading the data that composes that level from your pokey hard drive into your ram,
from a user’s perspective just follow this rule.
Ram allows you to run intensive programs while the 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 Mott.
And finally, we get to the graphics card. With all the calculations going on on your computer,
to turn a bunch of numbers that basically come down to ones and zeros into a constantly updated 3-dimensional world the final,
and most important in the 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 gonna be able to do much your graphics card is essential,
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.
Playing a game
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 well 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 the fast inverse square root,
which is directly related to how the 3-dimensional world calculates perspectives.
So that pretty much sums it up there are other components worth mentioning,
such as cooling systems and our internal wireless cards but really those are extra.
So to summarize what I talked about so far the case stores everything in a physical box the power supply.
It gives electricity to what needs it the motherboard is the body,
and everything plugs into the CPU and does everything ram stores data that is needed for quick access.
Drive store everything that you have installed and the data that goes along with those programs.
