Here is a general guide to the major computer components, what they do, and what usually happens when they get damaged / malfunction.
computer case:
This is probably what 75% of people in the world with a computer just to see. They probably never open this thing and really see what makes their work on the computer. There are several different sizes slučajeva.Glavni two computers are still mid-tower and the tower. The tower is about twice the size of the mid Tower and the possibility of packing more stuff into it. There are also "portable" cases that just look like large blocks.
computer case can have several different uses depending on the manufacturer and dizajn.Nekoliko things that used to be:
Protection of hardware!
Cooling your hardware!
provides easy access to the motherboard and other components, such as on the back of the computer with all the wonderful and plugs the holes? That when you plug in something there is a hook up or the motherboard or components, such as graphics cards, sound cards, etc.
so that the computer cases, the main function is basically to ensure that your hardware does not get damaged, and makes it easy for people who do not know much about computers the easy hook all the components and make it run.
Power Supply Unit (PSU )-
Probably one of the most important parts of your computer (well they are all important) and provide power for their motherboards, graphics cards, and everything else should be in your case. Most people know only as a power thing you plug the power cord to get power from the socket on the computer. They also have a wonderful fan plus!
The low quality of power often come with a case, however, you can always upgrade to higher quality brands such as Corsair or PCP & C
is a slew of power cables for connecting to different things, such as motherboards, disk drives, case fans, graphics card, etc.
Now the most important things you should look for when you buy the brand power and the amount of Watts puts out. As long as you get a brand that is first to third column you should be fine. As far as figuring out how many Watts you need to power the computer, check out the calculator powered by Google.
Motherboard (mobo ):
And this is the most important part of any computer. If the motherboard breaks, your best buy whole new computer, unless you customize it yourself. Motherboards contain a slew of connectors and slots, and when you put your first computer together it might be a little intimidating not knowing where to plug things.
Modern motherboards at a minimum include the following:
[*] main socket where you insert the CPU, which is then usually covered with a large cooling and / or fan.
[*] Slots where system memory is (RAM).
[*] Chip-set which makes the interface between the processor and the front-side bus, main memory and peripheral buses.
[*] Non-volatile memory chip containing the system firmware or BIOS for when you start up your computer
[*] Sat generator that acts as a time to synchronize the various computer components together.
[*] Expansion card slots, such as those for video or sound card.
[*] The main power connector, which receives power from the PSU and distributes it to the CPU, chip set, main memory, and sometimes the expansion cards, except of course that they provided their own power PSU.
It is important to always keep your motherboard cool, either through the radiator and fan, liquid cooling or extra case obožavatelja.Hotter your mobo gets, the shorter its life, and it is more likely to die. If your motherboard dies, you will notice that your computer will be able to function. If, however, notice a lot of problems with your hardware at once (like the graphics are messed up, as well as keyboard and mouse does not work), then most likely a problem with the motherboard.
a central processing unit (CPU ):
CPU is the brain of the computer and carries out its business. If you notice that your computer is running slow, outdated or bad CPU might be a problem.
on the laptop and desktop computers, the CPU is housed in a single chip, known as a microprocessor. Motherboards and processors are designed for each other, so do not try to put a brand new CPU to 4 year old motherboard, it will not work! If you ever open your computer, you probably will not see your CPU, you'll see a large refrigerator and ventilatora.Hladnjaka usually looks like a big block of thin sheets stacked closely zajedno.Ideja to create the largest area possible in the smallest amount of space to dissipate heat most possible .
As technology has grown over the years, there have been more and more advances in computing power, the original has only one core, but now newer versions contain even 4.Više cores you have, the more power you are able to handle the microprocessors. Multi-core processors also have the ability to multithread (they can be used by applications that support the work of 2 or 4 core CPU). 64-bit versions of operating systems are specially designed for multi-core CPU
Random Access Memory (RAM ):
Random Access Memory (which I will refer to as RAM) is a form of computer data storage that stores data in a temporary order to be accessed at any time, regardless of its physical location and whether or not this applies naprethodni information.
Type of RAM, a hierarchy is as follows
DDR3> DDR2> DDR
Pretty simple eh? You can usually tell what type of RAM your computer has the date it was built. If it was built recently and is of high quality computer then it probably has DDR3 RAM, if it was built a few years ago, or a regular computer built today then you probably have DDR2. If it is a very old computer, then it probably has DDR RAM.
Ram comes in several different sizes of rod, ranging from 512 to put the 2GB stick and will soon be palicama.Više 4GB of RAM you have, the faster your computer will run. But be careful not to put too much in, as it will be a waste of money, and the processor can act as a bottleneck, so the extra RAM is going to no use.
A few important issues other than the main types of RAM as its data rate (measured in MT / s, or millions of transfers per second), Command Rate (also known as clock speed, measured in Hz), ICAS latency (usually 4 sequential numbers ).
generally higher data rate and the Command Rate (which is usually half the data rate) the better. CAS latency, which measures the time delay between the memory controller and memory module, it is usually best when a small number.
If you are not sure how these names and numbers refer to the quality, just make sure that the RAM from a good brand. Some of the best are Corsair, Kingston and crucial.
Graphics:
Ahh graphics card, probably the most sought after and adapted part of the computer. Most low-end PCs do not include the graphics card, but integrated graphics chip in the motherboard. I would avoid these computers at any cost, because most likely you'll be able to play modern video games.
the two major graphics chipset manufacturers ATI and nVidia are. However, there are actually hundredth graphics card manufacturer. Some of the famous ones are the BFG, Sapphire, XFX and EVGA.
is an ideal graphics card for you all depends on what you need for it and your price range. You also have to decide for nVidia or ATI, personally I prefer nVidia though ATI is just as good. Both companies seem to match their cards, shot for shot, making sure one does not blow away the others. Instead, go in-depth decision graphics card comparisons, I thought I'd link you to a great article about tomsharedware. They always do very well in-depth reviews of graphics cards.
Hard disk:
Well, the hard drives are probably one of the main parts of a computer, they are used to store files, programs, etc.
Types of Storage drives:
hard drive - it simply contain one or more rotating disk. This can range from low up to 1.5 GB of storage-2TB drives. They also come in different speeds, which affects how fast they can access stored podataka.Redovito speed of 7200 rpm, but faster and more expensive plants can reach more than 10,000 rpm.
In addition to storage space and speed, it is also important to take your drive from a good producer, because saving a few bucks by taking it out of bad company can mean hard drive failure a few years or months, according doljeceste. Western Digital, Seagate, Hitachi and a few reliable brands.
Solid State Drive -. No moving parts, no spinning disks, much faster, much more expensive
I can not say much about SSD is here, because I've never owned one. Although in smaller sizes and storage are much more expensive, I have heard that they are incredibly fast compared to regular hard drives. They also have a lower life expectancy, however.
I think getting one for a new netbook, just to make it as fast as possible into the smallest container. If you are looking for max speed on your computer, insert your operating system on the SSD, and it will scream.
Note: There are both external and flash drives, but they are not part of the computer, and they are easy to use either
Optical drives:
is very simple, they are used for CD / DVD / Blue Ray reading. If the drive has an RW or + RW tacked on the end of it, it means you can both read and write CD / DVD / blue ray.
