what is d difference between flash memory n hard disk memory?

Flash memory is meant to be small and compact, such as flash drives and flash mp3 players. They're nice to have, but they dont have very good capacity (memorywise). Hard drive items are usually a bit more bulky, but have a lot more digital space. Hard drive memory simply means that data is saved onto a hard drive, and spins to access the data. I have no fricking clue what flash memory uses to work.

if you dont want all of those floopies and cd's you can always get a USB flash drive, i have one, and they come in many diffrent memory sizes such as 128 mb, 256 mb, 512 mb, and 1 Gb.  there really good, it also holds alot of memory.  its also small, so you can tie them around your neck and take them everywhere with you.  some of them is not that expensive, and its also very easy to use.  since its drive e:/ you just plug it on to the computer, and dave everything to drive e:/.

512 Megabyte is Bigger Than 32 megabyte\n\nJust Like 512 is bigger than 32

There is no difference. \n\nHowever, if you get two sticks, and there is a chance that one of your RAMS goes bad, then at least you have another one that will be a nice backup.\n\nIf you get just 1 stick, then it gives you the option of upgrading to 2 gigs in the future....otherwise you will have to pay for another 1 gig ram all over again. \n\nIf you have 4 slots, then get the 2 sticks if it saves you money.

Flash memory is a solid state (no moving parts) storage device.  It doesn't require power to retain its contents but is much slower than normal RAM.  It's meant to be a replacement for a disk or hard drive, but not system memory because of its slow speed.  It performs well compared to a zip drive but will not be as fast as RAM.  \n\nAlso, flash memory does wear out over time.  Every flash memory device has a certain number of writes and rewrites it can take before wearing out.  For normal use like copying files and digital photos, the lifespan is years and years, but RAM on a computer is rewritten millions of times/second, so  in this application it would not last very long at all.\n\nRAM is super fast but requires power to operate.  As soon as you cut the power to a RAM chip it loses its data.  Without going too far into the nuts and bolts of things, RAM is used for active tasks whereas flash memory is used for storage.

the difference is transmission of data\n\nddr is double data rate\n\n\nddr2 is next version of ddr

DDR I & DDR II\n\nif u mean maximum in MB / GB , i guess u get 2 GB each\n--- all depends what u'r motherboard is and supports

dont use ur old stuff unless its ddr2 ... if its older than 6 months it isnt ... dont mix the types or you'll slow everything down , just add another 512 if you have a SINGLE stick, and check out the site the guy above mentioned to get the same speed memory ... if you have two sticks of mem now they are 256 each and most likely in dual channel configuration ... in that case i would get the same speed memory but buy (2) 512s' or (2)1gig sticks ... if you break up a pair of sticks in dual channel or add a third you will slow things down also ...

no one seems to really know the lifespan.  As long as you avoid mishandling it, it should last quite a while...probably longer than you.  \n\nIn response to the answer above.  Flash memory is not at all like a hard drive.  The whole point of flash memory is that it's highly portable.  Hard drives have moving mechanisms that can become useless if bounced around.  That is why when you purhcase an mp3 player, you should know what kind of activities you will be doing with it - if you are jogging with it, you don't want one with a hard drive.

- A thumb drive has no moving parts and stores data in microscopic transistors.\n\n- A hard disk uses a spinning magnetic wheel and stores data as magnetic pits on a medium, sort of like a vinyl record.\n\nHard disks can usually hold more data, but thumb drives are catching up quickly, now reaching over 32GB in size for the largest ones.

ROM: Read Only Memory. Does exactly that; it can't write or erase data stored/burned on a disc.  \n\nThe vast volume of information, coupled by equally amazing fast speed of information retrivial quickly allowed the Compact Disc (CD) to phase out the cumbersome 5-inch floppy and the 'hard shell' 3 1/4 "square" disk drives.

What flash? The software, or the hardware? If the hardware, which one, there are many flash memory devices.

Heck!  Ipod! ipod not only has memory but also a music player. a Flash drive can only carry data. But Price wise flash drive is much less expencive.

Hard drives:\n  Size is nice, but there are a few differences.\n\nLook at the rpm speed of a hard drive.  Some are 5400 rpm, some are 7400, some are 10,000 rpm.  The higher the rpm, the faster the disks spin.  \n\nAlso look at the amount of cache on a hard drive.  Cache determines (more or less) how much can be moved around at a time.  Say for example a hard drive has 8 megabytes of cache, that means when you move files around, its doing so 8 megs at a time.  If you have a hard drive with 16 megs of cache, your files are moving at 16 megs which is double that of an 8meg cahce hard drive, and pretty much double the speed (in theory).\n\nRam/memory:\n\nAnother thing to watch out for is not only the size (amount) of memory you have, but also the speed.  Say for example your motherboard can support pc2100, pc2700 and pc3200 ram....with 2100 being the slowest and 3200 being the fastest.  It may be cool to have 2 gigabytes of ram, but check the speed.  I would personally rather have 512 megs or 1 gig of faster memory, than twice that of slower memory.\n\nThink of ram like being the size of your desk.  The more you have, the larger the desk.  At the same time though, think of the different speeds as that of the desk ahving a smoother surface that lets you slide your projects around.  Say you have a large desk and are working on project A and want to take a break and work on Project B for awhile before switching to project A again, when you switch to each project and drag the projects to the side, do you want them to snag and strain while pulling/pushing them?\n\nGraphics card:\n\nThis may be an issue too.  While standard onboard video is fine for most folks, if you are going to play games or use memory intesive apps, you may want a better video card.  Also note that the amount of ram on a video card doesnt necessarily mean you will get better performance.  I can pair up an fx5200 with 256 megs ram vs a 6800 with half the memory, and the 6800 will slap the fx5200 like a redheaded stepchild.\n\nProcessor:\n\nThis is an option easily upgradeable for most, but often overlooked.  Say you are running an older pentium 3 system running around 650 mhz, you can probably score a much faster processor of the same slot (say 1 ghz, or 933 mhz) on ebay for under $20\n\nI would recommend a program called Everest which will tell you exactly what hardware you have, what socket/pins etc and go from there

First off, your computer itself has 2 types of memory. Ram and Rom. Ram is the place where your programs are loaded when you run them. Rom is the place where your programs are stored. When you run a program, the brain or processor loads the program from rom to ram. A flash drive is nothing more than an electronic storage device that allows you to store files or data on it. It isnt much different than the ram your PC uses other than it keeps data stored until its erased. Ram in your PC however differs slightly, it will dump its memory contents to load a new program or when you shut down your PC.

well really depends on what kind of hardrives you have are they IDE or SATA?? sata has raid features on it so you can  also doesnt matter how much space yor disks have to spped up ur system it reallt matters on the system ram

How much storage and portability do you need. If it's up to around 2GB go for the flash, otherwise you're in HDD territory.
