USA
UK
A non-volatile (permanent) memory type that is erasable via ultra-violet light and re-programmable.
USA
UK
EPROMs are popular for use in critical firmware applications, such as BIOS's, because they are both non-volatile and they can be updated when necessary.
USA
UK
A legacy storage device which can read and write data slowly from a removable magnetic medium (normally 3.5" in diameter and holding 1.44 MB of data).
USA
UK
Floppy disk drives were once included with almost all computers, but are now considered obsolete.
USA
UK
A storage device using rotating magnetic platters to store and retrieve data.
USA
UK
A hard disk drive can fail at any time, normally causing data corruption and loss.
USA
UK
A storage technique using patterns of charged particles on a metallic surface to store data.
USA
UK
Magnetic drives have been around since the 1950s and are typically used to store large amounts of data.
USA
UK
Long-term, persistent, does not require power to retain its state.
USA
UK
The laptop contained 500MB of non-volatile storage.
USA
UK
A data storage technique using a pattern of markings on a disc that can be read by a laser; examples include CD-ROM, and DVD-ROM technology.
USA
UK
Optical storage is a good choice for distributing software packages because it has a good mix of storage size, portability, and a low cost to manufacture.
USA
UK
An interface between light and matter that allows for the storage and retrieval of entangled photonic qubits.
USA
UK
A practical quantum memory solution must be able to reliably store and recall quantum states on demand at room temperature.
USA
UK
A type of computer memory known for being volatile (temporary) and fast.
USA
UK
My computer was performing slowly when changing programs, so my technician installed more RAM and this solved the problem.
USA
UK
A type of memory which is known for being non-volatile (permanent) and fast.
USA
UK
The boy gave a puzzled look when the man showed him an old Atari 800 computer ROM cartridge.
USA
UK
A type of storage using integrated circuits to store data; examples include RAM, ROM, and flash memory.
USA
UK
All computers created today use at least some form of semiconductor storage.
USA
UK
A storage device characterized by high speed, no-moving parts, and low energy consumption.
USA
UK
Many new laptop models use solid state drives, although they are more expensive and have less capacity than traditional hard disk drives.
USA
UK
A cluster of storage devices working together to provide shared network storage.
USA
UK
With cloud hosting, your virtual server's performance is often at the mercy of latency in the SAN.
USA
UK
Memory intended specifically for the graphics processor.
USA
UK
Modern games such as GTA V load textures which can fill gigabytes of dedicated video memory.
USA
UK
Temporary, requires power to retain its state.
USA
UK
Due to it's volatility, the RAM lost all the data when the user tripped over the power cord.
