Sb\u011brnice je fyzick\u00e9 propojen\u00ed mezi SD kartou a p\u0159\u00edstrojem (fotoapar\u00e1t, \u010dte\u010dka karet, telefon, atd) a n\u00e1sledn\u00fd p\u0159enos dat (fotky, videa, …) \u0159\u00edzen\u00fd protokolem.

Trochu odborn\u011bj\u0161\u00ed a obecn\u011bj\u0161\u00ed popis z Wikipedie.<\/p>\n

Sb\u011brnice (anglicky bus) je skupina sign\u00e1lov\u00fdch vodi\u010d\u016f, kterou lze rozd\u011blit na skupiny \u0159\u00eddic\u00edch, adresov\u00fdch a datov\u00fdch vodi\u010d\u016f v p\u0159\u00edpad\u011b paraleln\u00ed sb\u011brnice nebo sd\u00edlen\u00ed dat a \u0159\u00edzen\u00ed na spole\u010dn\u00e9m vodi\u010di (nebo vodi\u010d\u00edch) u s\u00e9riov\u00fdch sb\u011brnic. Sb\u011brnice m\u00e1 za \u00fa\u010del zajistit p\u0159enos dat a \u0159\u00eddic\u00edch povel\u016f mezi dv\u011bma a v\u00edce elektronick\u00fdmi za\u0159\u00edzen\u00edmi. P\u0159enos dat na sb\u011brnici se \u0159\u00edd\u00ed stanoven\u00fdm protokolem.<\/p><\/blockquote>\n
