2. 16-line message format - Wikipedia

   en.wikipedia.org/wiki/16-line_message_format

   16-line message format, or Basic Message Format, is the standard military radiogram format (in NATO allied nations) for the manner in which a paper message form is transcribed through voice, Morse code, or TTY transmission formats. The overall structure of the message has three parts: HEADING (which can use as many as 10 of the format's 16 ...

   en.wikipedia.org/wiki/Turing_machine_equivalents

   A Turing machine is a hypothetical computing device, first conceived by Alan Turing in 1936. Turing machines manipulate symbols on a potentially infinite strip of tape according to a finite table of rules, and they provide the theoretical underpinnings for the notion of a computer algorithm.

4. One-time pad - Wikipedia

   en.wikipedia.org/wiki/One-time_pad

   A few British one-time tape cipher machines include the Rockex and Noreen. The German Stasi Sprach Machine was also capable of using one time tape that East Germany, Russia, and even Cuba used to send encrypted messages to their agents. [31] The World War II voice scrambler SIGSALY was also a form of one-time system. It added noise to the ...

5. Linear Tape-Open - Wikipedia

   en.wikipedia.org/wiki/Linear_Tape-Open

   Linear Tape-Open (LTO), also known as the LTO Ultrium format, [1] is a magnetic tape data storage technology used for backup, data archiving, and data transfer.It was originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats available at the time.

6. Magnetic-tape data storage - Wikipedia

   en.wikipedia.org/wiki/Magnetic-tape_data_storage

   Modern tape drives offer a speed matching feature, where the drive can dynamically decrease the physical tape speed as needed to avoid shoe-shining. [23] In the past, the size of the inter-block gap was constant, while the size of the data block was based on host block size, affecting tape capacity – for example, on count key data storage. On ...

7. Turing machine - Wikipedia

   en.wikipedia.org/wiki/Turing_machine

   The machine operates on an infinite [4] memory tape divided into discrete cells, [5] each of which can hold a single symbol drawn from a finite set of symbols called the alphabet of the machine. It has a "head" that, at any point in the machine's operation, is positioned over one of these cells, and a "state" selected from a finite set of states.

8. Linear Tape File System - Wikipedia

   en.wikipedia.org/wiki/Linear_Tape_File_System

   Oracle's free open source StorageTek Linear Tape File System (LTFS), Open Edition software [10] is claimed to be the first to store 8.5TB (native capacity) on a single cartridge. It supports Oracle’s midrange StorageTek LTO 5 and LTO 6 tape drives from HP and IBM as well as Oracle’s StorageTek T10000C and T10000D tape drives. [11] [12]

9. P versus NP problem - Wikipedia

   en.wikipedia.org/wiki/P_versus_NP_problem

   For example, the problem of deciding whether a graph G contains H as a minor, where H is fixed, can be solved in a running time of O(n 2), [25] where n is the number of vertices in G. However, the big O notation hides a constant that depends superexponentially on H .
