Data Erasure
Data erasure (sometimes referred to as data clearing, data wiping, or data destruction) is a software-based method of data sanitization that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by overwriting data onto all sectors of the device in an irreversible process. By overwriting the data on the storage device, the data is rendered irrecoverable. Ideally, software designed for data erasure should: #Allow for selection of a specific standard, based on unique needs, and #Verify the overwriting method has been successful and removed data across the entire device. Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to the data disk sectors and make the data recovery possible with common software tools. Unlike degaussing and physical destruction, which render the storage media unusable, data erasure removes all information while leaving the disk operable. New flash memory-based m ...

Data Sanitization
Data sanitization involves the secure and permanent erasure of sensitive data from datasets and media to guarantee that no data remanence, residual data can be recovered even through extensive forensic analysis. Data sanitization has a wide range of applications but is mainly used for clearing out end-of-life product, end-of-life electronic devices or for the sharing and use of large datasets that contain sensitive information. The main strategies for erasing personal data from devices are physical destruction, cryptographic erasure, and data erasure. While the term data sanitization may lead some to believe that it only includes data on electronic media, it also broadly covers physical media, such as paper copies. These data types are termed soft for electronic files and hard for physical media paper copies. Data sanitization methods are also applied for the cleaning of sensitive data, such as through heuristic-based methods, machine-learning based methods, and k-source anonymity. ...

Electronic Hardware
Electronic hardware consists of interconnected electronic components which perform analog or logic operations on received and locally stored information to produce as output or store resulting new information or to provide control for output actuator mechanisms. Electronic hardware can range from individual chips/ circuits to distributed information processing systems. Well designed electronic hardware is composed of hierarchies of functional modules which inter-communicate via precisely defined interfaces. Hardware logic is primarily a differentiation of the data processing circuitry from other more generalized circuitry. For example nearly all computers include a power supply which consists of circuitry not involved in data processing but rather powering the data processing circuits. Similarly, a computer may output information to a computer monitor or audio amplifier which is also not involved in the computational processes. See also * Digital electronics Digital elect ...

Laptop Theft
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is in the lower part, under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers. Laptops are used in a variety of settings, such as at work (especially on business trips), in education, for playing games, content creating, web browsing, for personal multimedia, and for general home computer use. They can run on both AC power and rechargable battery packs and can be f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iomega REV
REV is a removable hard disk storage system from Iomega, released in 2004.http://web.archive.org/web/20040604143936/http://www.pocket-lint.co.uk/review.php?reviewId=404 The small removable disks store 35, 70, or 120 gigabytes (GB) and are hard-drive technology. Like a standard hard drive, the REV system uses a flying head to read and write data to a spinning platter. The removable disks contained the platter, spindle, and motor, while the drive heads and drive controller are contained within the REV drive. The drives allow for data transfer rates of about 25 megabytes (MB) per second. The REV was available as an external desktop model with FireWire, SCSI or USB 2.0 interfaces, an internal model with SCSI, ATAPI, or SATA interfaces, or an external server model which features a cartridge autoloader and SCSI interface. Iomega also offered a 320 GB network-attached storage appliance which features a built-in REV. The drives are compatible with Macintosh, Windows, and Linux op ...

Iomega Jaz Drive
The Jaz drive is a removable hard disk storage system sold by the Iomega company from 1995 to 2002. Following the success of the Iomega Zip drive, which in its original version stores data on high-capacity floppy disks with 100 MB nominal capacity, and later 250 and then 750 MB, the company developed and released the Jaz drive. First shipping to OEMs in December 1995, the Jaz drive featured 1 GB capacity per removable disk. A new Jaz drive model, released in February 1998, increased the individual disk capacity to 2 GB. The Jaz drive uses a SCSI interface, with both internal and external drive models. Iomega produced a Jaz Jet SCSI adapter PCI card for PCs. Iomega also produced a number of external adapters, including the Jaz Traveller interface that connected it to a standard parallel port, and, later, a SCSI-USB adapter and SCSI-Firewire adapter. An ATA version of the drive was planned but never released. Reception The Jaz never attained as much success or market penetratio ...

Iomega Zip Drive
The Zip drive is a removable floppy disk storage system that was announced by Iomega in 1994 and began shipping in March 1995. Considered medium-to-high-capacity at the time of its release, Zip disks were originally launched with capacities of 100 MB, then 250 MB, and finally 750 MB. The format became the most popular of the superfloppy products which filled a niche in the late 1990s portable storage market. However, it was never popular enough to replace the standard -inch floppy disk. Zip drives fell out of favor for mass portable storage during the early 2000s as CD-RW and USB flash drives became prevalent. The Zip brand later covered internal and external CD writers known as Zip-650 or Zip-CD, despite the dissimilar technology. Overview The Zip drive is a "superfloppy" disk drive that has all of the standard -inch floppy drive's convenience, but with much greater capacity options and with performance that is much improved over a standard floppy drive. ...

Flash Memory
Flash memory is an Integrated circuit, electronic Non-volatile memory, non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR gate, NOR and NAND gate, NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level, depending on whether the state of the bit line or word lines is pulled high or low; in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented by Fujio Masuoka at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than the entire devi ...

Universal Serial Bus
Universal Serial Bus (USB) is an industry standard, developed by USB Implementers Forum (USB-IF), for digital data transmission and power delivery between many types of electronics. It specifies the architecture, in particular the physical interfaces, and communication protocols to and from ''hosts'', such as personal computers, to and from peripheral ''devices'', e.g. displays, keyboards, and mass storage devices, and to and from intermediate ''hubs'', which multiply the number of a host's ports. Introduced in 1996, USB was originally designed to standardize the connection of peripherals to computers, replacing various interfaces such as serial ports, parallel ports, game ports, and Apple Desktop Bus (ADB) ports. Early versions of USB became commonplace on a wide range of devices, such as keyboards, mice, cameras, printers, scanners, flash drives, smartphones, game consoles, and power banks. USB has since evolved into a standard to replace virtually all common ports on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Server (computing)
A server is a computer that provides information to other computers called " clients" on a computer network. This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients or performing computations for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are usually most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgment. Designating a computer as "server-class hardwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Security Number
In the United States, a Social Security number (SSN) is a nine-digit number issued to United States nationality law, U.S. citizens, Permanent residence (United States), permanent residents, and temporary (working) residents under section 205(c)(2) of the Social Security Act, codified as . The number is issued to an individual by the Social Security Administration, an Independent agencies of the United States government, independent agency of the United States government. Although the original purpose for the number was for the Social Security Administration to track individuals, the Social Security number has become a ''de facto'' national identification number for Taxation in the United States, taxation and other purposes. A Social Security number may be obtained by applying on Form SS-5, Application for a Social Security Number Card.

Hardware-based Full Disk Encryption
Hardware-based full disk encryption (FDE) is available from many hard disk drive (HDD/ SSD) vendors, including: Hitachi, Integral Memory, iStorage Limited, Micron, Seagate Technology, Samsung, Toshiba, Viasat UK, and Western Digital. The symmetric encryption key is maintained independently from the computer's CPU, thus allowing the complete data store to be encrypted and removing computer memory as a potential attack vector. Hardware-FDE has two major components: the hardware encryptor and the data store. There are currently four varieties of hardware-FDE in common use: #Hard disk drive (HDD) FDE (self-encrypting drive) #Enclosed hard disk drive FDE #Removable hard disk drive FDE #Bridge and Chipset (BC) FDE Hardware designed for a particular purpose can often achieve better performance than disk encryption software, and disk encryption hardware can be made more transparent to software than encryption done in software. As soon as the key has been initialised, the hardwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
