what is the diffence between a GB and a MB .... Example .. thier is the 512 mb, 2 GB , 1 GB waht is the differnce between that .. Which one has more memory the loower # or the higher # .. Thank you to those Who can help me ? 1024 Mb = 1 Gb. You want the highest Gb possible if you want the most memory. Standard flash memory sizes would be 256 Mb (1/4 of a Gb), 512 Mb (1/2 of a Gb), 1 Gb, 2 Gb, etc. Realize that a 2 Gb card will hold over 1,000 pictures depending on the resolution of the camera and what you have the camera set to. You have to decide for yourself if it is worth the extra money to get the higher memory cards or not. There's nothing wrong with having a 512 Mb memory card; it just means you'll have to load them onto the computer more often. If you never have the desire to have more than 300 or so pictures on your camera at a time, then a smaller card may do you just fine! mb is mega byte and gb is gig byte one million mb make up i gb.
the high the number in gb is higher and mb is lower. The more memory, the more it uses your power. I use a 1 GB on a 5mb camera. I cannot fill the card without having to recharge. But, you can do a 15 minutes movie on it, lol.
SID GB means that it contains more memory. My sisters camera works well with a 1 GB. MB means it is less than a GB. You would be better off by getting a memory card that is in GB. GB is higher than MB. So if you want the hightest memory go with 2GB. A gb is 1024 mb. 256mb with a 3megapixel camera will give about 130 pix. 1gb will give about four times that amount.
When you buy the camera, get one that uses SD/mmc cards. SD is probably the format that will stay around, because that is what Kodak uses. I suggest 256mp cards, or more.
If you go over 2gb you need to be sure the camera uses fat32 format. At this time, it is required to use over 2gb.
Also, if you have more than one card, get a card storage wallet.
They have cards all the way up to 8gb, but they are pricey. A gigabyte is 1000 times the size of a megabyte.*
How many photos you can store on each.
That depends on a whole lot of things. The best way to find out is to pick out the camera(s) first. They have the best estimates (within a couple of %) of how many will fit on what size card.
Divide the GB ones by 1000 to compare with the MB (or mb) ones. Then, the higher number will store more.
After you've done that, divide the price by the number of MB it has to get the cost per MB of storage (in cents) to compare them price-wise. (example: $20 for a 512MB card = 0.0390625 - or 4 cents a MB).
If the costs are close, you may wish to consider 2 or more cards versus one huge one. The largest ones usually cost the most and hurt the worst when you loose one.
*Technically a GB is 1024 times the size of a MB, but 1000 is close enough and a whole a lot easier to figure. Most of the people already told u that 1024MB(Mega Byte) = 1 GB(Giga Byte). I would add further that the higher GB card (2GB,3GB,4GB) is useful to those only who watch & keeps their pics on Camera only or who make movies more often on digital cam. Because 4GB Card can make at least 1 hour movie. If u dont do that more often and tranfers ur pics immidialtly on Computer or take prints, then 512MB or Max. 1GB Card is good enough for u. For the average user, a 512MB memory card is probably enough.
But many people these days are opting for a larger capacity card such as 1GB (which is roughly double the size of the 512MB card).
Sometimes its not much dearer to buy the 1GB card anyway.
Also, shooting 'movies' with your camera requires a lot of memory, so a 1GB card would be the absolute minimum. And if you are going away for a holiday, then you could easily need much more memory.
As an example, a 5MP-6MP camera will allow approx. 150-200 photos on a 512MB card (using fine/best quality resolution, which you should always use)...and 'movies' will eat up memory fast. (high quality could allow only approx 8-10 mins per 1GB).
So, I recommend at the very least that you buy a 1GB card. While we're at it, let's talk about brand names.
Sandisk and Lexar come bundled with image recovery software that you copy onto your computer before you format the card. I am sure that the cards all pretty much perform the same, but these brands have a lifetime warranty for some of their products, so that makes me think they are built to higher standards. As far as day-to-day use, I have some generic and some of each brand I named and they all work. The contacts on the brand name cameras seem to have the equivalent of the "thunk" that you look for when you shut a car door to check it's quality, if you know what I mean. You don't wonder, "Is it in there right?" because it just feels right. I don't buy generics any more, though. I just end up getting them "with things" somehow. I just got one free with a Palm PDA I bought, for instance. |
