Ale v\u017edy\u0165 i vy sami ji\u017e n\u011bco m\u00e1lo zn\u00e1te a um\u00edte. \u017de ne? Pokud um\u00edte obsluhovat mobiln\u00ed telefon, tak m\u00e1te minim\u00e1ln\u00ed z\u00e1klady a ani o tom nev\u00edte. Tak jak jste se u\u010dili \u0159\u00eddit auto, u\u010dili jste se z\u00e1klad\u016fm informa\u010dn\u00edch technologi\u00ed a o to obsluze jednoho z nich. Schv\u00e1ln\u011b, vzpomenete si na to? Asi ne. Kdopak by si to pamatoval. To u\u017e je let\u2026\u00a0Jakoukoli z\u00e1kladn\u00ed jednotkou \u010dehokoli z tohoto sv\u011bta je bit. Je to zkratka z anglick\u00e9ho binary digit \u2013 dvojkov\u00e1 \u010d\u00edslice. Kdo nen\u00ed hon\u011bn\u00fd v matematice, bude m\u00edt jist\u00e9 drobn\u00e9 pot\u00ed\u017ee v ch\u00e1pan\u00ed toho co bude n\u00e1sledovat. Nic si z toho ned\u011blejte. J\u00e1 to nech\u00e1pu tak\u00e9 a \u017eiju. Tak tedy m\u00e1me bit, z\u00e1klad informace, co\u017e je stav, kter\u00fd bychom vyj\u00e1d\u0159ili jako ano, nebo ne. Nula nebo jedni\u010dka. Bit m\u016f\u017ee m\u00edt jen tu neb onu hodnotu. Nepl\u00e9st si s pojmem, bajt. Bajt je toti\u017e tak\u00e9 mal\u00e1 jednotka informace, ale je to ji\u017e osm bit\u016f. Kdy\u017e uvid\u00edte velk\u00e9 B, znamen\u00e1 to bajt, mal\u00e9 b pak zna\u010d\u00ed bit. \u00a0D\u00e1le to nebudeme pitvat, proto\u017ee to bychom musel rozebrat dvojkovou soustavu a tak\u00e9 se bavit o tom, \u017ee to nemus\u00ed b\u00fdt zrovna osm bit\u016f, ale po\u010det m\u016f\u017ee b\u00fdt jin\u00fd. Dnes v dne\u0161n\u00edch technologi\u00edch se v\u0161ak pou\u017e\u00edv\u00e1 osm, a tak to d\u00e1le nebudeme pitvat.

Bohu\u017eel, pokud budete hledat spr\u00e1vn\u00fd v\u00fdklad, naraz\u00edte na to, \u017ee si ka\u017ed\u00fd p\u00ed\u0161e, co chce. Plete byty a bajty dohromady a \u010dlov\u011bk nev\u00ed, co je fakt.

Jen\u017ee, zn\u00e1te to, \u017ee. \u00a0Nu\u017ee tedy vid\u00edte, \u017ee i vy jste na chvili\u010dku zab\u0159edli do slo\u017eit\u00e9 struktury IT.
