V roce 1958 vznikla firma ARPA, po kter\u00e9 se tak\u00e9 pojmenoval p\u0159edch\u016fdce internetu \u2013 arpanet. P\u016fvodn\u011b tato s\u00ed\u0165 m\u011bla za \u00fakol poskytovat komunikaci prim\u00e1rn\u011b vojensk\u00fdm slu\u017eb\u00e1m. Internet u\u017e d\u0159\u00edve m\u011bl b\u00fdt decentralizovanou s\u00edt\u00ed. To znamen\u00e1, \u017ee tato s\u00ed\u0165 nem\u011bla \u017e\u00e1dn\u00e9 centrum. Pokud se p\u0159eru\u0161ila n\u011bjak\u00e1 cesta, kterou mohla komunikace prob\u00edhat, tak prob\u00edhala komunikace jinou. M\u016f\u017eete si to p\u0159edstavit t\u0159eba jako pavu\u010dinu. Kdy\u017e se p\u0159etrhne jedno vl\u00e1kno, nespadne hned cel\u00e1 pavu\u010dina.

Mnoz\u00ed z v\u00e1s si internet p\u0159edstavuj\u00ed jen jako webov\u00e9 str\u00e1nky. Jen jako google, wikipedii a podobn\u011b. Dovolte mi ale vyv\u00e9st v\u00e1s z omylu. Internet je opravdu velik\u00e1 s\u00ed\u0165 a poskytuje stra\u0161n\u011b moc slu\u017eeb. Webov\u00e9 str\u00e1nky jsou jedn\u00edm z nich. \u00b7 Email.

Webov\u00e9 str\u00e1nky jsou obecn\u011b velice slo\u017eit\u00e9. Vyu\u017e\u00edvaj\u00ed dost protokol\u016f a hodn\u011b skriptovac\u00edch jazyk\u016f. V\u00edte ale, \u017ee webov\u00e1 str\u00e1nka nem\u00e1 n\u00e1zev takov\u00fd, jak ho zn\u00e1me? Ka\u017ed\u00e1 str\u00e1nka m\u00e1 nejd\u0159\u00edve svou IP adresu, kterou pak DNS (domain name system) zm\u011bn\u00ed v dom\u00e9nu, kterou zn\u00e1me. \u00b7 FTP.
