If you are dealing with an HD camera than you want at least 8, but with sd cameras 4 should do.
No.
No, a memory card reader is not required if your camera has a usb cable.
Sadly when you buy the camera it doesn't come with a card. I would suggest getting at least 2gb memory for your sd card, 8gb if you plan on taking more video.
This will depend on your camera. If your camera has an internal memory card, you will need a cord to connect your camera to your computer's USB port. If your camera has a removable memory card, simply plug that into your computer, or into a memory card adapter if needed.
If the camera has a slot for the memory card, slide it in and they should automatically save there. If not you'll need a different method of saving.
well, pictures need to be stored SOMEWHERE on your camera, right? just like how our memories store information, memory cards store the pictures you take. a camera without a memory card is about as good as no camera at all.
Most digital camera's on the market nowadays need a internal memory card. These may come in various forms like compact flash, SD cards, Memory sticks, etc. You will need to find the brand and model to help you find out what kind of memory card you will need. Most digital camera's will tell you what kind of memory card it takes where you insert it on the camera. The store where you bought your camera from should carry memory cards and/or they should be able to advise you in what kind to get. These memory cards can be purchase online or at many electronic or department stores. Depending on your camera's mega-pixels you may need a larger memory card to hold more photos.
Check your camera's manual. Your memory card may need to be formatted. CAUTION: do not do this to a card with photos already on it because formatting will erase anything on the card. Check that it is the correct type of memory card & that your camera's battery is charged. If all else fails go to a reputable camera shop (or the shop you bought the camera from) & ask for help.
the memory between the video card and the mother board DO NOT need to match. the memory on the vid card CANNOT be upgraded.
the kind that goes in a video camera.
The camera has about 50MB of internal memory and accepts SD/SDHC memory media
The memory card is what the digital files are stored on. If you have no memory card in your camera there is nowhere for the camera to store the files. It is like not putting a film in a film camera or trying to burn a CD with no CD inserted to the drive. No Some digital cameras have internal memory so you don't need a memory card.
