Storage Devices

Hard Disk Drive

*A hard disk drive (HDD) is a non-volatile, random access device for digital data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read and written on the platter by read/write heads that float on a film of air above the platters.

Ram

*RAM is the most common type of memory found in computers and other devices, such as printers.

There are two different types of RAM: DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory).

Blue tooth

* gives you a wireless connection between your PC and device. Note that not all computers have built-in Bluetooth. You can however use the data cable or infrared connection instead to make the connection.
