application software
  نرم‌افزار ِ آتاهشی   
narm-afzâr-e âtâheši

Fr.: logiciel d'application   

A software with a specific function, such as a word processor or game. Contrast with operating system software.

application; → software.

soft
  نرم   
narm (#)

Fr.: mou   

General: Delicate in texture, grain, or fiber.
Not bright or glaring.
Physics: Of a beam of particles or electromagnetic radiation, having relatively low energy, as opposed to → hard. → soft X-rays

M.E. softe "yielding, gentle, mild;" O.E. softe "gentle, easy;" cf. O.S. safti, O.H.G. semfti, Ger. sanft, M.Du. sachte, Du. zacht.

Narm "soft; smooth; mild," from Mid.Pers. narm "soft; humble."

soft binary
  درین ِ نرم   
dorin-e narm

Fr.: binaire mou   

In → stellar dynamics studies of → three-body encounters, a → binary system whose → binding energy is smaller than the typical → kinetic energy of the relative motion of an incoming third body. See also → hard binary.

soft; → binary.

soft gamma repeater (SGR)
  بازگرشگر ِ گامای ِ نرم   
bâzgaršgar-e gâmmâ-ye narm

Fr.: répéteur gamma mou   

A member of a small class of objects which emit intense bursts of → gamma rays and → X-rays (> 100 keV) at irregular intervals. The bursts last for some 100 milli-seconds. It is conjectured that they are → magnetars. See also → starquake.

soft; → gamma rays; → repeater.

soft gamma-ray repeater (SGR)
  بازگرشگر ِ پرتوهای ِ گامای ِ نرم   
bâzgaršgar-e partowhâ-ye gâmmâ-ye narm

Fr.: répéteur des rayons gamma mous   

Same as → soft gamma repeater (SGR).

soft; → gamma ray; → repeater.

soft iron
  آهن ِ نرم   
âhan-e narm

Fr.: fer doux   

Iron that has a low carbon content, in contrast to → steel. Because it is easily magnetized and demagnetized, it is used to make the cores of → solenoids and other electrical equipment.

soft; → iron.

Soft X-ray Transient (SXT)
  گذرای ِ پرتو ِ ایکس ِ نرم   
gozarâ-ye partow-e X-e narm

Fr.:   

An → X-ray binary system that has a long period of → quiescence interrupted by → outbursts of low-energy → soft X-rays. Alternatively known as X-ray novae, the majority (~ 75%) of SXTs contain a → black hole and a low-mass → main sequence  → companion star in orbit around one another. It is thought that SXTs arise in a similar manner to → dwarf novae, through instabilities in the → accretion disk around the → compact object (→ disk instability model).

soft; → X-ray; → transient..

soft X-rays
  پرتوهای ِ ایکس ِ نرم   
partowhâ-ye iks-e narm

Fr.: rayons X mous   

X-ray photons with energies between about 0.1 to 10 keV. → hard X-rays.

soft; → X-rays.

software
  نرم‌افزار   
narm-afzâr (#)

Fr.: logiciel   

A general term used to describe a collection of computer programs, procedures, and documentation that perform some tasks on a computer system. → hardware.

soft + ware, from M.E., from O.E. waru, from P.Gmc. *waro (cf. Swed. vara, Dan. vare, M.Du. were, Du. waar, Ger. Ware "goods").

Narm, → soft + afzâr "instrument, means, tool," from Mid.Pers. afzâr, abzâr, awzâr "instrument, means," Proto-Iranian *abi-cāra- or *upa-cāra-, from cāra-, cf. Av. cārā- "instrument, device, means" (Mid.Pers. câr, cârag "means, remedy;" loaned into Arm. aucar, aucan "instrument, remedy;" Mod.Pers. câré "remedy, cure, help"), from kar- "to do, make, build;" kərənaoiti "he makes" (Pers. kardan, kard- "to do, to make"); cf. Skt. kr- "to do, to make," krnoti "he makes, he does," karoti "he makes, he does," karma "act, deed;" PIE base kwer- "to do, to make").
