Memory Card is now widely used, e.g. If.-MMC (MultiMedia Cards) Card is a memory garden, old model is not currently in use and popularity because it is expensive and there is very little capacity. Which is the maximum capacity at 512 MB.-SD Card (Secure digital card) is a popular capacities currently in use, which have a small size portable simultaneously with a capacity that is greater than a MMC and a fast data transfer with higher.-MicroSD card (CompactFlash card) is a CF Memory Card SD the same type of garden, but they are much smaller in size. Use with modern electronic devices.-MS (Memory stick) is made from card companies, Sony has the ability to transfer data at much higher, but it is rarely appreciated implemented. by MS card will be available with the Sony products only, and that is more expensive than other types of memory.But the capacities of the popular SD Card which is currently has been continually active development as a MicroSD card that is smaller than the SD Card, and works with many types of electronic devices nowadays.SD Card section is subdivided into three categories, which are divided according to the capability of data capacity, as follows:1. SD Card (Secure Digital) with a capacity of 4 MB to 4 GB, since a card that will work with General electronic devices that do not require a lot of storage capacity.2. Card SDHC (Secure Digital High Capacity) memory card with a capacity up to 4 GB. 32GB electronic device with a new version that requires a storage capacity greater.3.
