    Their first calculator with a microprocessor is the Busicom 141-PF. Their entry based calculators, the Busicom LE-120A (Handy-LE) and LE-120S (Handy) , [ 6 ] were the first to fit in a pocket and also the first calculators to use an LED display.

  4. Programmable calculator - Wikipedia

    en.wikipedia.org/wiki/Programmable_calculator

    Originally, calculator programming had to be done in the calculator's own command language, but as calculator hackers discovered ways to bypass the main interface of the calculators and write assembly language programs, calculator companies (particularly Texas Instruments) began to support native-mode programming on their calculator hardware ...

    en.wikipedia.org/wiki/Mean_time_between_failures

    The Mil-HDBK-217 reliability calculator manual in combination with RelCalc software (or other comparable tool) enables MTBF reliability rates to be predicted based on design. A concept which is closely related to MTBF, and is important in the computations involving MTBF, is the mean down time (MDT). MDT can be defined as mean time which the ...

    en.wikipedia.org/wiki/Fetch-and-add

    In computer science, the fetch-and-add (FAA) CPU instruction atomically increments the contents of a memory location by a specified value.. That is, fetch-and-add performs the following operation: increment the value at address x by a, where x is a memory location and a is some value, and return the original value at x.

    PM WIN-T provides the communications network (satellite and terrestrial) and services that allows the Warfighter to send and receive information in tactical situations. WIN-T is the transformational Command and Control system that manages tactical information transport at theatre through Company Echelons in support of full spectrum Army operations.

  8. Increment and decrement operators - Wikipedia

    en.wikipedia.org/wiki/Increment_and_decrement...

    The post-increment and post-decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to the increment (or decrement) operation. In languages where increment/decrement is not an expression (e.g., Go), only one version is needed (in the case of Go, post operators only).

  9. Special number field sieve - Wikipedia

    en.wikipedia.org/wiki/Special_number_field_sieve

    In number theory, a branch of mathematics, the special number field sieve (SNFS) is a special-purpose integer factorization algorithm. The general number field sieve (GNFS) was derived from it. The special number field sieve is efficient for integers of the form r e ± s , where r and s are small (for instance Mersenne numbers ).
