If you work with computer's 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 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 gonna give a very broad and general overview a typical's 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 house's everything else some of them have more or less physical space some of them have different part's where you can put screws in 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 provide's all of the other part's 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 mentions 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 sends electrical current's composing data between each other well 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 units.
And processor these terms all refer to the same thing there clearly interchangeable Ram stands for random access memory and is often referred to as just a memory a hard drive is often referred to as a disk drive or storage and a graphics card is also known as a GPU.
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 programs or a project files 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 allow's you to run intensive program's while disk space allows you to have more of these and 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 a bunch of numbers that basically come down to one and zeros into a constantly updated 3-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 gonna look good and it's certainly not gonna be able to do much your graphics card is essentially an entire computer.
If itself 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 figure 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 component's worth box the power supply gives electricity to what means it the motherboard is the body that everything plugs into the CPU does everything Rams 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...
