RAM stands for Random Access memory\nROM stands for Read Only memory\n\nSo, when you burn a CD, that information may be accessed and used whenever you like, but it cannot be changed.\n\nWhen you start your computer, you access different files for writing, internet, etc and you alter and manipulate them. You send letters to friends, you type IM messages to family members.  That is using the RAM within your computer.

DVD +R DVD -R DVD+RW DVD-RW\n\nthe diffrence between a +R and a -R is when coming to record a dvd movie... the +r comes out with a slight better quality then - R thought it is only noticable on a LCD Screen\n\nThere is also +RW and -RW same as above but they can be rewritten on

A DVD Writer is the ultimate drive available at the moment it can do everything read DVD'S, write DVD'S, read CD's and write CD's.\n\nA Combi Drive is usually a CD Writer and A DVD Rom drive in one, which means it can only Read DVD's and write and read CD's.\n\nBasically a Combi drive cannot write DVD's.

Yep. It's just a DVD rom, not a burner. 40x CD read, 8x DVD read.

physical memory is the hardware (RAM) installed in a computer, whereas virtual memory is when the computer runs out of physical memory and starts using the hard drive to store data.

DVD and CD-ROM are not the same technology, and not only due to layering. The methodologies of storing and reading data is different. It's complicated to explain, and probalbly not what you are after. \n\nThe net effect is that from the layman's perspective, the only difference between a data CD and a data DVD is in the amount of space available.\n\nThe + and - signs indicate the type of technology used for a DVD drive. The two are not compatable; you need DVD+R discs for a DVD+R drive and a DVD-R drive needs DVD-R discs. \n\nYou can find out the kind of drive you have by right-clicking My Computer, choosing the Hardware tab, clicking the Device Manager button, then clicking the plus sign next to the DVD-CD drives entry. Your drive will be listed like "_NEC DVD+R 8X MFD34322" or the like.\n\nYou'll probably be happier with DVD discs for backup because you'll need fewer. However, considering how cheap external USB 2 hard drives are, and that DVDs still cost 50 cents each, you should consider investing in an external hard drive instead.

CD-r burns on the bottom of the disk, where a CD+R burns on the top.  There is really no difference in terms of use.

CD-RW writes only CDRoms with max capapcity of 700mb, while DVD-RW writes DVD disks up to 4.7gb and up to 8bg on Double-Layered DVD disks. \n\n4.7gb DVD blanks are more common. Commercial studios publish their movies to 8gb DVD disks.  They usually have more than sufficient space to throw in extras like interviews, making of the movies and so on.\n\nWhen you want to legally backup your copy of DVD movies you have to shrink the movies from 8gb down to 4.7gb to fit. VCD and SVCD format of up to 1150bps may be burned to multiple CDRoms, while DVD have a higher cinematic quality of anything from 5000bps to 9000bps and need only 1 disk to contain a whole movie.\n\nBurning Movies to DVD quality is the only way to go these days.\n\nNow the latest technology is Blu-Ray disc with capacity of up to 20gb. Wouldn't be available for a while though.

No DVd players play RAM files.  RAM files are actually stored online and the RAM file is just the link to it, thereofre in order to play a RAM file, you need an internet connection, which DVD players do not have.

they are 2 different Ram formats ... SD Ram is older and is identified by 2 notches along the contact edge where DDR Ram only has 1 notch approx in the middle ... You CAN NOT place SD Ram into a DDR Ram DIMM or vice-versa

RAM = Random Access Memory. This type of memory is "short term" meaning when you turn the power off everything in it is gone. This type of memory is incredibly fast when it comes to moving data around. When you load a program from your hard drive or CD it "executes" in RAM. When you close the program the RAM is typically free'd up to be used again. This is often confused with the type of memory that your Hard drive servers as, which is long term memory. When you power off your computer the data on a hard drive remains. Compared to RAM the data manipulation speed of a hard drive is a very small fraction of its speed.\n\nROM = Read Only Memory. This type of memory is Read Only. Typically a ROM in a computer is a single chip (however, multiple components can have their own ROM chips like a video card, a hard drive controller and the main motherboard in your computer). ROM memory typically stores the "Firmware" (otherwise known as the BIOS) which is NOT hardware and is NOT software, but sits in the middle. When I say in the "middle" I literally mean that. Any program (such as Microsoft Windows XP) has to go through a ROM routine (i.e. software instructions of how to access a piece of hardware)in order to use a device driver to access a hardware device, such as a hard drive or USB key or even write data to a video card. ROM memory is NOT lost when the computer is turned off. ROM memory is also not changeable. The type of ROM memory that can be changed or "reprogrammed" is an EPROM (or an EEPROM) chip.\n\nNow that you know about memory, don't forget it! :)\n\nUnc

ROM or Read Only Memory, Computers almost always contain a small amount of read-only memory that holds instructions for starting up the computer. Unlike RAM, ROM cannot be written to. It is non-volatile which means once you turn off the computer the information is still there.\n\nRAM (Random Access Memory) is a temporary (Volatile) storage area utilized by the CPU. Before a program can be ran the program is loaded into the memory which allows the CPU direct access to the program.

You Can to your device manager, if its windows XP right click on my computer, go to Manage and then device manager, look under your cd-rom and or dvd-rom and click on proeperties it should say the type of rom it is.

Yes, if the mobo is rated for that capacity. Why the 2 CD-ROMs? I'd go with at least 1 DVD-RW. The DVD-RW will give you more flexibility.
