Flash memory card is an electronic data storage device used to store digital information, you can store text, prictures, audio and video. It could also be used in digital camer, mobile phones, video game consoles, etc.
Floppy disk and zip disk

Floppy disk stores and trasfers data from your computer. It has a hgih capacity, which is much greater than a USB flash drive, memory card, etc.
Zip disk is a removeable disk storage system. It has a medium capacity. It allows a fast and easy transfer of data from your PC.

The CPU or processor stores and retrieves infroamtion fromit. It has two types of technologies: ROM (Read only memory) and RAM (Read access memory) which is also known as RWM (read write memory). This is much faster than the secondary memory.

A secondary memory is much slower and less costly. It stores data permanently unless it is erased. It is kept on a long term bases. Secondary memory are hard disk and floppy disk.
Tertiary Memory
tertiary memory is used to store data. It involves robotic mechanism which inserts and removes mass storage media into a storage device.
