we deal in all types of storage devices
hard drive
A small hard drive typically has only one platter, but each side of it has a magnetic coating. Bigger drives have a series of platters stacked on a central spindle, with a small gap in between them. The platters rotate at up to 10,000 revolutions per minute (rpm) so the read-write heads can access any part of them.
floppy disk
A floppy disk is a lot like a cassette tape: Both use a thin plastic base material coated with iron oxide. This oxide is a ferromagnetic material, meaning that if you expose it to a magnetic field it is permanently magnetized by the field. Both can record information instantly.
usb
Most people use USB for computer mice, keyboards, scanners, printers, digital cameras, and USB flash drives. There are over six billion USB devices around the world. The standard was made to improve plug and play devices. This means that a device can be plugged into a free socket, and simply work.
ram
The chips that make up a computer's internal memory come in two broad flavors known as RAM (random access memory) and ROM (read-only memory). RAM chips remember things only while a computer is powered on, so they're used for storing whatever a computer is working on in the very short term.
memory card
A memory card, flash card or memory cartridge is an electronic flash memory data storage device used for storing digital information. These are commonly used in portable electronic devices, such as digital cameras, mobile phones, laptop computers, tablets, PDAs, portable media players and video game consoles.
cd-rom
Short for Compact Disc Read-Only Memory, a CD-ROM is an optical disc which contains audio or software data whose memory is read only. A CD-ROM Drive or optical drive is the device used to read them.
