Apvalkalas

Apvalkalas (angl. shell) – išorinis programos sluoksnis, sukuriantis sąsają tarp tos programos ir jos naudotojo.^[1] Įprastai operacinių sistemų apvalkalai naudoja komandų eilutės sąsają (CLI) arba grafinę sąsają (GUI), priklausomai nuo kompiuterio paskirties ir reikalingos užduoties. Vadinamas „apvalkalu“, nes tai yra tolimiausias operacinės sistemos sluoksnis.^[2]^[3]

That program, which he described as a “shell” around the computer’s whirring innards, gave inspiration—and a name—to an entire class of software tools, called command-line shells, that still lurk below the surface of modern operating systems."
