    Can someone teach me about computers?

    I know a lot of you know about computers here. I just wanna know more about them. For instance it can be Ram for instance. Tell me what it's all about. Please!

    RAm and Graphics cards are very important to guys like you Silver. Especially when you have a subscription and have the availability of 1080p full hd.

    What are you trying to say?!

    I would like to know about graphic cards. I know they are used in consoles.

    They have a certain amount of cores which run at mhz i guess and the gpu has also an amount of vram. Both are required to be decent in order to watch the videos with good performance.

    Memory IS Ram.

    Alright here we go.

    Memory is a blanket term for anything within a computer that can retain data- for however long. It is simply a 'container'. Memory has many forms.

    RAM stands for "Random Access Memory"- and it is volatile memory. This means that when the machine is no longer being powered with electricity, everything it is storing vanishes. It is called "Random" because the data located anywhere within the RAM can be retrieved as quickly as any other place- it just reaches out and 'grabs' it.

    So say A.jpg is loaded on one part of the RAM chip (This is just a simple illustration) and B.jpg on another. The data for either image can be 'grabbed' and accessed just as fast as the other. It really doesn't matter where it is stored within memory (RAM).

    This stands in contrast to permanent memory, like with a hard drive (which is magnetic storage. RAM is non-magnetic. This is why you should keep magnets away from your hard drive, as it will start to scramble\rewrite it and corrupt data).

    So you might ask, well what's so special about RAM? Why use it? Well, its invaluable because of how damn fast it is. Exponentially faster than a hard drive is at reading\writing data. For performance reasons it is simply a must that the CPU get fed information as quickly as possible. The other reasons are also cost and technological barriers of achieving RAM amounts equivalent to what a hard drive can possess.

    There is an old saying that goes: "Your fleet is only as fast as your slowest ship". So in order to help things move smoothly and quicker, there are 'buffers' where data resides to be used. The first place is the hard drive, which then has temporary data (which needs to be fed very quickly) moved to RAM, which is then used and reused by the CPU for as long as it requires. So when you "load" a game what is really happening is, the data on the hard drive is being fed (loaded) into RAM for quick access.

    There are also various kinds of RAM. DRAM, SDRAM, EDRAM, etc..

    And there are particular types of RAM technology like DDR, DDR2, DDR3, DDR5, XDR, GDDR (almost all graphics cards use GDDR for its on chip memory).

    As a rule of thumb, most computers (desktops, laptops) have separate 'pools' of memory. One chunk (often some type of DDR) for the CPU or central processing unit often called "system memory" and a chunk for the GPU or graphic processing unit called "video memory" (often abbreviated VRAM, normally GDDR). This is often called "Non-Unified Memory Architecture" or NUMA.

    Some devices (like the Xbox 360, mobile devices\embedded hardware) share this memory for equal access for both the GPU and CPU. This is often called "Unified Memory Architecture" or UMA.

    There are other kinds of memory in a computer too, like the BIOS and CPU cache (L1, L2, etc).

    Solid State Drives, which are very much akin to RAM, is on the rise. This is a type of flash memory that uses no moving parts or magnetism and can permanently store data without power. It is much, much faster than any hard drive but also far more expensive. Hard drives can still hold far more data at a lower cost then the SSD's though, so there is still a 'barrier' in its adoption.

    The rate at which data can be moved from memory to a processing unit (GPU\CPU) is often called "bandwidth" and is measured in Gigabits per second or "Gb/s". Please do not confuse this with "Gigabytes" per second. The same applies for Megabits per second- Megabits =/= Megabytes.

    This is kind of confusing for alot of people, and the more you go into computer engineering nitty gritty or telecommunication\networking technology the more you see these terms thrown around. Like your home router or cable service for instance.

    It might say "20Mbs speed!" or what have you. This is not megabytes per second, but megabits.

    1 megabyte = 8 megabits.

    MB = megabyte
    Mb = megabit

    1 gigabit = 8 gigabytes

    GB = Gigabyte
    Gb = Gigabit

    In conclusion:

    Don't listen to all the stuff up above my post. All you need to know about computers is the following:

    10101011111010001010111010100001010101010101010101 0000111100011

    That's all it comes down to on the most basic level.
