A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc , and usually weighs less than 30 g (1 oz).
The Dead Drops project was conceived by Berlin-based conceptual artist Aram Bartholl, a member of New York's F.A.T. Lab art and technology collective. The first USB dead drop network of five devices was installed by Bartholl in October 2010 in Brooklyn, New York City. [2] The name comes from the dead drop method of communication used in espionage.
This technique may need to be modified for multi-level cell devices, where one memory cell holds more than one bit. Common flash devices such as USB flash drives and memory cards provide only a block-level interface, or flash translation layer (FTL), which writes to a different cell each time to wear-level the device. This prevents incremental ...
Data General developed operating systems for its hardware: DOS and RDOS for the Nova, RDOS and AOS for the 16-bit Eclipse C, M, and S lines, AOS/VS and AOS/VS II for the Eclipse MV line, and a modified version of UNIX System V called DG/UX for the Eclipse MV and AViiON machines. The AOS/VS software was the most commonly used DG software product ...
Data is compressed in 16-cluster chunks (up to 64 KB in size); if the compression reduces 64 KB of data to 60 KB or less, NTFS treats the unneeded 4 KB pages like empty sparse file clusters—they are not written. This allows for reasonable random-access times as the OS merely has to follow the chain of fragments.
The next version was the Nova 2, with the first versions shipping in 1973. The Nova 2 was essentially a simplified version of the earlier machines as increasing chip densities allowed the CPU to be reduced in size. While the SuperNOVA used three 15×15" boards to implement the CPU and its memory, the Nova 2 fitted all of this onto a single board.
The prevalence of malware infection by means of USB flash drive was documented in a 2011 Microsoft study [6] analyzing data from more than 600 million systems worldwide in the first half of 2011. The study found that 26 percent of all malware infections of Windows system were due to USB flash drives exploiting the AutoRun feature in Microsoft ...
NOVA was developed at the University of California, San Diego, in the Non-Volatile Systems Laboratory of the Computer Science and Engineering Department. [2] [3] Patches were initially made available for version 4.12 of the Linux kernel. [4] As of 2017 it is limited to x86-64 Linux, and not ready for merging with the upstream kernel. [3]
