Off-line storage is computer data storage on a medium or a device that is not under the control of a processing unit. [9] The medium is recorded, usually in a secondary or tertiary storage device, and then physically removed or disconnected. It must be inserted or connected by a human operator before a computer can access it again.
The phonograph cylinder is a storage medium. The phonograph may be considered a storage device especially as machines of this vintage were able to record on blank cylinders. On a reel-to-reel tape recorder (Sony TC-630), the recorder is data storage equipment and the magnetic tape is a data storage medium.
Track positioning also follows two different methods across disk storage devices. Storage devices focused on holding computer data, e.g., HDDs, FDDs, and Iomega zip drives, use concentric tracks to store data. During a sequential read or write operation, after the drive accesses all the sectors in a track, it repositions the head(s) to the next ...
The minimal chunk size (page) for a read operation is much smaller than the minimal chunk size (block) for a write/erase operation, resulting in an undesirable phenomenon called write amplification that limits the random write performance and write endurance of a flash-based storage device. Some solid-state storage devices use RAM and a battery ...
Data storage device, a device for recording information, which could range from handwriting to video or acoustic recording, or to electromagnetic energy modulating magnetic tape and optical discs; Object storage device, computer storage device; Portable storage device, small hard drive or pen drive
Today the term external storage most commonly applies to those storage devices external to a personal computer. [5] The terms refer to any storage external to the computer. Storage as distinct from memory in the early days of computing was always external to the computer as for example in the punched card devices and media. Today storage ...
The computer case holds the motherboard, fixed or removable disk drives for data storage, the power supply, and may contain other peripheral devices such as modems or network interfaces. Some models of desktop computers integrated the monitor and keyboard into the same case as the processor and power supply.
A direct-access storage device (DASD) (pronounced / ˈ d æ z d iː /) is a secondary storage device in which "each physical record has a discrete location and a unique address". The term was coined by IBM to describe devices that allowed random access to data, the main examples being drum memory and hard disk drives . [ 1 ]
