arrsid16258056 Compact discul constitue un alt suport de memorie externa cu caracteristici superioare fata de discurile flexibile . CD-ROM-ul Copmact Disc Read Only Memory reprezinta suportul de memorie in plina ascensiune datorita facilitatilor deosebite pe care le prezinta, atat in ce priveste tehnologia avansat de fabricatie,cat si in ce priveste modul de organizare si de accesare a informatiilor .Stocarea si accesarea datelor de pe CD-ROM-uri, se realizeaza prin mijloace optice cu o viteza mult mai rapida, care reduc numarul de componetnte mecanice si maresc fiabilitatea suportului.tpar Stpardtplain tltrpartqj tli0tri0tidctlpartaspalphataspnumtfaautotadjustrig

56tcharrsid16258056 Istoria CD-ROM-urilor nu este prea indepartata de zilele noastre. Preocuparile in acest domeniu se remarca indeseobi dupa anul 1980, in urma unei intelegeri intre renumitele companii Philips shi Sony. Pana la aceasta data fiecare dintre cele doua companii realizase, dupa propriile conceptii si tehnologii,anumite variante de CD-ROM-uri insa abia in anul 1982, ca urmare a intelegerii stabilite, acestea au definitivat standardul actualelor CD-ROM-uri.Discurile CD-ROM si discurile CD-audio sunt asemanatoare unii spun identice dar in acelasi timp sunt si diferite unele fata de altele.Ele sunt identice ca suport,ca principiu de citire,si ca marime si format fizic,insa difere din punct de vedere al continutului informational si al unitatilor hard pentru inregistrare si redare.Un CD-audio, introdus insa intr-o unitate hard de CD-ROM,va putea fi citit si redat fara probleme.tpar Principalele caracteristici de performamta ale unitatilor de CD sunt tpar Itpntexttpardtplaintltrpar trtlchtfcs1 taf0tafs20 tltrchtfcs0 tfs28tlang1033tlangfe1033tlangfenp1033tinsrsid1625

Acest parametru se masoara in milisecunde shi este mai mare ca la HD, fiind cuprins ,in medie, intre 100 ms. si 400 ms. iar la cele mai moderne scade sub 100ms.Astfel in timp ce la hard disk-uri timpul de acces se situeaza sub 20 milisecunde , la CD-ROM-uri timpul de acces nu scade cu mult sub 100 milisecunde .Timpul mare de acces se explica, in primul rand, prin faptul ca la fiecare accesare CD-ul trebuie adus la o anumita viteza de rotire, in timp ce hard disk-ul are o viteza de rotatie cons...
