A computer is a very use full electronic device. This device is very powerful and complex it includes many types of parts. Some components are easy to recognize such as a computer case, keyboard and, monitor, and other types of hardware components, but today we will know that there is some kind of hardware inside the box attached to it.
What is the type of parts inside your computer case? Explain.
- Power Supply
- Central Processing Unit (CPU)
- Random Access Memory (RAM), Or Volatile Memory
- Storage: Hard Disk drive Storage (HDD), Or Solid State Drive (SSD)
- Graphic Processing Unit (GPU), Or Video Card
These are the fundamental parts of any desktop computer let’s spread these into two categories simple ones and more complex ones.
A First Simple One Case, Power Supply, Motherboard.
The case is nothing more than a big chunk of the 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 to that but at the end of the day, all the case does provide a nice enclosed system for everything else.
We have a power supply that always resides at the bottom of the computer case, which is connected to the power socket, which provides electricity to other components parts with the electricity needed to do their thing you can think of it is a highly advanced AC adapter.
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 composing data between each other.
It will not particularly expensive the motherboard is arguably 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 onto the more complex parts computer the ones that deal with data the four main components CPU, RAM hard drive, SSD, and graphics card.
Central Processing Unit (CPU)
Let’s start with the CPU first, A CPU is also known as the central processing unit or processor These terms all refer to the same thing they’re completely interchangeable.
The CPU is where the computer does things it isn’t 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 quickly and massive calculations needed to run your programs this is where most of your programs are essentially run from it often referred to as the brain of the computer.
I don’t like this description because really year entire computer is just a brain it’s just the center part of your computer’s brain everything that happens in your computer now passes through your CPU at some point.
Now let’s learn about RAM and hard drives at the same time because they have a very unique relationship which is probably why people often confuse the two.
Hard Disk Drive (HDD)
A hard disk drive Is a data storage device your hard drives are where all of your data is stored when your computer tells you you’re low on space it’s because your hard drive is almost full of all of the data that makes up your videos, pictures, documents, project files or models that makes up a game are all stored here.
While hard drive cannot store lots of data they’re relatively bad at accessing that data quickly everything is accessed through a tiny-tiny 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 comes in RAM.
Solid State Drive (SSD)
SSDs, Smaller, faster, and better – most of the time A solid-state drive SSD is a type of nonvolatile storage media that stores continuously data on solid-state flash memory. Flash drive popular forms of SSD unlike a hard disk drive or HDD, an STD has no moving parts.
A spinning HDD reads and writes data magnetically. It’s an old and reliable method, but vulnerable to mechanical breakdowns.
An SSD, in contrast, reads and writes the data a substrate of interconnected flash memory chips, which are fabricated out of silicon.
Manufacturers build SSDs by stacking chips in a grid to obtain varying densities. SSDs are faster and more durable than HDDs thanks to falling flash prices SSDs are becoming increasingly popular in business and consumer-level PCs and laptops.
SSDs have faster seat time and lowest latency than HDDs, as well as faster boot time in particular high-performance servers, laptops, desktops, or applications that need to deliver information in real-time benefit from SSD technology.
SSDs employ wear-leveling and garbage collection to increase drive lifespan, which slows right performance and limits usable storage. SSDs also have a defined life expectancy with a finite number of write cycles before performance becomes erratic.
Looking at price per gigabyte, SSDs are still much more expensive than HDDs, which are still a relatively reliable way to store data this is why businesses typically use both HDDs and SSDs. Would you consider adding solid-state storage to your business if you haven’t already?
Random Access Memory (RAM)
RAM is used for random access memory and is often referred to as memory only. RAM is another form of storage It stores the same type of information as your hard drive but RAM is sacrificed storage space for nearly instantly accessibility unlike your hard drive which sends all of its data through a tiny little thin wire you RAM is arranged in this long fence sticks that insert into your motherboard.
Think about a storage unit if you have a huge warehouse with only a thin doorway. It is gonna 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 long wide storage shed that’s got a big gigantic garage composing an entire side of it you won’t be able to store it as much more but things are significantly easier to get.
Typically If your computer has a thousand gigabytes of storage space in your hard drive it’s likely to get 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 be able to get in and out of quickly when you ran a program or a project file
Your CPU identifies which parts of data are needed to run that program, it pulls them from your hard drive and then stores them in your RAM wicks. for access this is why when you start a new level of a game, for instance, it has to load anytime you see it loading, it is loading data that composes that level from your bulky hard drive into your RAM from your hard drive.
From a user point of view just follow this rule of thumb RAM allows you to run intensive programs while hard disk space allows you to install more of these programs installed it also allows you to have more of the data they’re referencing whether it pictures videos or mod.
Graphic Processing Unit (GPU)
A graphic card is also known as a GPU or graphic processing unit 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 frequently updated 3-dimensional world.
The final and most important and arguably most difficult step is to demonstrate that on your monitor your motherboard can do this alone but it is not going to look good and it is certainly not capable of much.
Your graphics card is essentially an entire computer in and of itself dedicated to the sole task of figuring and what pixels need to light exposed on your screen in what color and at what time.
If you were playing a game that had a very busy and highly textured world with lots of models and different angles and colors, then you are the CPU. That creates the 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 graphic card figures out what it’s supposed to look like based on where you’re standing in the world.
