Pentru a modela si manevra informatiile, calculatorului lucreaza cu date.
\n Date <\/strong>\u2013 reprezentarea informatiilor in memoria interna(M.I.)
\nSe foloseste sistemul binar cu cifrele 0 si 1.
\nCantitatea de informatie elementara e numeste BIT { 0,1}
\n Bitii <\/strong>sunt grupati in Byte(octet) = 8 biti
\n–\tKilobyte(KB) = 2 la a 10 a = 1024 B
\n–\tMegabite(MB) = 2 la puterea 10 KB = 2 la puterea 20 a B
\n–\tGigabite(GB) = 2 la puterea 10 MB= 20 la puterea 20 KB = 2 la puterea 30 B
\n BIT<\/strong>-ul este atomul informatiei iar zona de memorie adresabila este octetul.
\nModelarea fizica a sistemului binar este comutatorul.
\nToate datele din memoria unui calculator sunt codificare.
\n
\nCodificarea<\/strong> \u2013 este ofunctie care face ca elementele unei multimi de date sa corespunda elementele altei multimi de coduri. Astfel incat la doua elemente distincte sa corespunda 2 coduri distincte. Pentru codiciarea in binar a caracterelor se folosesc:<\/p>\n

– caracterele alfabetice. A.S.C.M. Fiecare character de pe tastatura are atribuit o secventa binara(unica) ca succesiune de cifre binare
\n– caracterele numerice \u2013 sunt reprezentare in binary pentru nr naturale. In cod complementar pentru intregii negative se numeste virgula fixa si virgula mobile.<\/p>\n
