Ce este un software?

Imagine Software22

Problema cand vorbim despre computere este aceea ca cei mai multi dintre noi nu intelegem limbajul acestora.

In acest caz avem nevoie de un traducator care sa puna computerul sa lucreze pentru noi.
Aici intervine software-ul.
Fara software, calculatorul ar fi pentru majoritatea o simpla cutie pe care nu ar intelege-o si in consecinta nu ar putea-o folosi.
De ce?
Pentru ca un claculator cunoaste o singura limba numita cod binar. Codul binar este format din 1 si 0.

Imaginati-va ca aveti o zi obisnuita la birou. Porniti calculatorul si in loc de iconitele cu care ne-am familiarizat ar aparea o multime de 0 si 1.

Cam greu de descifrat aceasta limba fara ajutorul unui software, nu?

Fiecare software are scopul lui.
De exemplu, pentru a desena o imagine sau pentru a scrie un text avem nevoie de un software special care stie sa faca acest lucru.

Un software se poate obtine cumparandu-l de la magazin sau descarcandu-l de pe internet.
Exista si software care pot dauna calculatorului. Acestea au fost create in scop distructiv si pot fura informatii dintr-un anumit calculator.
!!!Aveti mare grija ce software descarcati de pe internet!!!

Un software este creat cu ajutorul unor limbaje de programare (C++, Java, Perl, etc). Aceste limbaje de programare transforma cu ajutorul unui compilator software-ul din limba pe care noi o cunoastem in cod binar (limba calculatorului).

Cele mai multe computere au doua tipuri principale de software:
1.Sistemul de operare 
2.Programele software

Un software poate fi :
-furnizat odata cu calculatorul
-creat ulterior de catre utilizator
-cumparat gata din magazine

Hardware-ul este partea fizica a unui calculator. In general, pentru a functiona, un calculator are nevoie de ambele componente, dar si de datele care trebuiesc prelucrate. Gama de produse a componentei software este formata din sistem de operare, drivere si programe de aplicatii. In unele cazuri, pana si purtatorii fizici de date sunt considerati ca fiind un software, ca de exemplu casetele video VHS si MiniDV, unitatile optice de tip CD/DVD etc.
