So my speech is manly going to be about what do computer parts do inside of a computer.

This is just going to be a general overview so I won’t talk to much about how each part was maid and stuff like that.

So a normal computer has 7 essential things.
Case
Power supply
Motherboard
CPU
Ram
Hard Drive
And a graphics card.
These are the fundamental parts of a computer.
I’m going to break it down into 2 groups.
Simple ones and the more complex.

Simple ones:

Let's start off with the case.
The case is usually made out of plastic or metal. There are a lot of different cases  but they all go around the general idea that you put all your components inside of them. I don’t think that you can build a computer without a case but you can try.

Next thing I’ll  do is the power supply.
The power supply is what connects to the wall and provides all the parts the electricity needed to do their thing.It’s almost always located on the bottom.
Some power supplies are module which means that all the cables come off so that you can just plug in the ones you need but they are usually more expensive.

Now I’ll do what I think is the most important part: The motherboard.

The motherboard is a wide and flat circuit board that all the other components plug into. It’s the part that let's all the components plugged into it send electrical currents composing data between each other. Motherboard’s aren’t too expensive to buy ranging from around $50 to around 300$ depending on the one you bought.

Now to the Complex parts.
The 4 main components to keep in mind here are the CPU, RAM, Hard Drive, and graphics card. These parts mostly deal  with data. Let me makes some terminology here.

The CPU is also known by Central Processing Unit or Processor. All of these mean the same thing just spelled differently.
Ram could also mean Random Access Memory and is often referred to as memory.
A Hard Drive is also known as the disk drive or storage.
And the graphics card is also known as the GPU  or Graphics Processing Unit.
In this speech I will be using the terms CPU, RAM, Hard Drive and GPU.

So let's start with the CPU.
The CPU is where your computer does things.
It isn’t good at storing much data at all but its very good with doing things with data from quickly reading it, arranging it, and 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 like 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 because they have a very unique relationship.

Your Hard Drive is where all your data is stored. When your computer says to you that you’re running low on space, it’s because your Hard Drive is almost full. All of the data that makes up your documents, videos, pictures and anything else that uses data are all stored in a Hard Drive.

While the Hard Drive is saving your data, its bad at accessing that data quickly. Everything is accessed through a tiny little wire and because most Hard Drives are made up of spinning  disks, your hard drive isn’t going to be able to be constantly give your  CPU information it needs to run certain programs.

Thats where Ram comes in.
Ram is another form of storage. Its stores the same exact data as your Hard Drive but Ram sacrifices storage space for nearly instant accessibility. Unlike your hard drive that 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. Let's think about it like this, if you have a huge warehouse with stuff inside but only a thin doorway, it's going to be difficult to find what you need and get out. But if you have a small storage shed with a big garage on one side of it. You won’t be able to store much but things are easier to get to.

When you run program, your CPU identifies what parts of data are needed for that program to run. It takes the data from your hard drive and then stores them in your RAM  sticks for quick accessibility. This is why every time you start up a game and its loading, it's getting the data that it needs for that level from your hard drive into your ram.
Think of it like this. The ram handles  programs while the hard drive allows you to get more of them.

And finally we get to the graphics card or gpu.
The GPU is what does a lot of calculations to project a 3d image. You can do this with motherboard but it won’t look nearly as good as having a GPU. Your GPU is essentially and
Your GPU is essentially an entire computer in and of itself dedicated to do the only task of figuring out what pixels need to light up on your screen in what color and at what time.

If your playing a game that has a very busy and high texture world with lots of models and different angles and color, your CPU is what creates that world. It knows where  the stuff is and it does so with data that’s been stored with your Ram that came from your hard drive but it’s your GPU that figures out what it's supposed  to look like based on where you’re standing in the world.

So that pretty much sums it up. There are other components that are like cooling systems or  internal wireless cards but those are just extras.

So to summarize what I talked  about is the case is used for putting all your components inside of.
The power supply is used for power all the parts.
The motherboard is the body that everything plugs into.
The CPU does everything.
RAM stores data that is needed for quick access.
The Hard Drive is used for storing data.
And the graphics card is what is used to to figure out how everything looks on your monitor.

Thanks for listening and if you have guys have any questions, just ask me.
