I'm questioning my knowledge of computers.

post #1 of 12
Thread Starter 
I thought I have a decent understanding of computers untill my friend started asking me questions lol. Ive realized that I know lots about hardware and what's good what's bad. But I don't fully know the exact jobs of the specific parts, and how exactly they affect the proformance of the computer. I'm going to make a list of parts and my understanding of them. I will then update them with better definitions.

Please feel free to give any input, I'm doing this so I no longer can say "I don't know" when people ask me basic computer questions.

CPU: Basicly the brain of the computer. Controlls all of the processes. The faster the CPU the faster software can run?

GPU: Controls the graphics and how good the picture looks.

Ram:??

MoBo: Holds all the parts in place?

HDD: The storage place of all computer data

SDD: Just a much faster way to store data. Data can be pulled from storage much faster.

Again, I know my definitions are very bleek so please feel free to give better definitions. Thank you in advance

Cpu executes applications,

applications(processes) stored in memory for the cpu to execute.

HDD, stores data when not needed for execution, or when not enough memory is available, at which you need to use the swap space.

GPU, just does the work related solely to displaying things.

So Data from the HDD goes temporarily to the RAM? Then it's run by the CPU?

Also what is [Raid 0] - [Raid 5]? I see alot of talk about this.

Sorry if this thread is in the wrong section. Mod can go ahead and move this if possible.

See video.
The guy has other videos explaining how other raid arrays work.
In short terms, in raid 0 (2 drivers for example) the data is written on both drivers so half the data is on the first drive and half on the second drive. This way, read and write speeds are basically double but if one HDD fails in a Raid 0 array, you lose all your data because its spread evenly on all HDDs so you get left with incomplete data thats worthless.

CPU-not just how fast software runs, but more of how fast it 'processes' it. Video encoding is a perfect example. For software to 'run' faster, you would also need a SSD to decrease seek times and fast ram to back it all up.
It makes a difference in gaming also... but keep in mind most games are limited to 4 cores... not much games take advantage of more than 4 cores...

RAM is random access memory that simply is "Volatile" meaning it requires constant power to run, meaning once you restart or lose power, this memory will be wiped. The more you have of this, the more programs can be held running at the same time... or in video editing, Native 64 bit programs like Adobe CS5 Premier can edit longer video lengths at the same time(based on how much RAM you have)...

The Mobo doesn't just hold all pieces together, but is like the "Mother of all boards." This connects everything together, and the motherboard is as good as all the components that connect to it..

*edit* seeing your specs, i'm surprised you asked that many questions... did you build the system yourself?

Completely Off Topic: joemaniaci your avatar wins the most disturbing award~ That crazy SOB abducted his last victim 5 min from my house...As funny as a Top ranked officer in ladies lingerie is concerned I get it but he was twisted monster of a human (if you can call him human) even placing him as an avatar on a forum is more than he deserves.

On topic: I'm in the same boat but I never claim to be a computer expert just a hardware enthusiast, I know what each part does roughly but when it comes to software and the engineering I'm lost.

The best would be to open wikipedia? Or you want for somebody to quote it in here?

CPU: Brain that executes and process applications
RAM: Temporary memory that stores instructions and stuff before being processed
HDD: Main storage and is allocated a swap space so that software, instructions etc can be stored so that you don't use up all the RAM
GPU: in charge of display
Motherboard: Provides an interface for everythign to interconnect and communicate in a way. though modern CPU's combined with a PCH/NB are mostly responsible for intercommunications of a computer nowadays.
SSD: Non-volatile flash memory based storage. Very fast, but degrades as you write data to it. (talking millions of writes here) Expensive gb/$ ratio. Uses alot less power than traditional HDDs and is quiet and not affected by vibrations

hope that helps
