binary field

dvejetainis laukas statusas T sritis informatika apibrėžtis ↑Įrašo ↑laukas, kurio visi bitų deriniai gali būti panaudoti duomenims koduoti. Pavyzdžiui, jeigu duomenų bazės įrašo laukas yra vieno bito, tai jame galima laikyti informaciją apie asmens lytį, užkoduotą 0 ir 1, jeigu vieno baito – dvejetainiu kodu užkoduotą skaičių iš intervalo nuo 0 iki 255. Tokiam pačiam skaičiui reikėtų trijų baitų tekstinio lauko. Todėl dvejetainiai laukai ekonomiški, bet į juos pateikiamus duomenis reikia konvertuoti iš tekstinio pavidalo į dvejetainį, o išvedamus – atvirkščiai. atitikmenys: angl. binary field ryšiai: dar žiūrėkįrašas dar žiūrėklaukas dar žiūrėklaukas dar žiūrėklaukas palyginktekstinis laukas
