Memory cards

Digital cameras function with the help of digital technology which provides enhanced picture quality. In the beginning there were cameras run by analog formatting which contained film strips where the photographs were stored. However, these analog cameras are slowly fading into oblivion and are being replaced by these digital versions where the storage is taken care of by different means. In the functioning of digital cameras, memory cards or the flash memory cards are very significant as they act as a storage device and act as electronic data storage equipment.

Memory cards are useful not only for the digital cameras, but they are also helpful for use in video game consoles, computers, music players, computers etc. These are high performance gadgets which allow power-free storage capacities and the ability to re-record according to one’s convenience and requirements. Often referred to as ‘mem cards’, most of them are solid-state cards, while some others may be non-solid state memory cards which do not use flash memory. There can be different classifications for memory cards on the basis of their functioning in different devices. For example the first memory card format to come out during the 1990s was the PC card or the PCMCIA though it is primarily used for industrial applications at present. Some other kinds of memory cards like Miniature card, SmartMedia, CompactFlash were also introduced from time to time. In case of even mobile phones and gaming consoles, smaller memory cards were used which remained fixed to the device.

Since the year 2000, there has been introduced various different kinds of memory cards like PDAs, Memory Sticks, xD-picture card, SD/MMC etc. However, for use on digital cameras, the most prevalent formats have been the CompactFlash and SmartMedia and at present various kinds of Memory Stick versions and SD/MMC are also used for the proper functioning of digital cameras.
