The heritage of computing will be informed because the tale of and software program, or the tale of the web, or the tale of "smart" hand held units, with subplots regarding IBM, Microsoft, Apple, fb, and Twitter. during this concise and available account of the discovery and improvement of electronic know-how, computing device historian Paul Ceruzzi deals a broader and extra valuable point of view. He identifies 4 significant threads that run all through all of computing's technological improvement: digitization--the coding of data, computation, and keep an eye on in binary shape, ones and zeros; the convergence of a number of streams of recommendations, units, and machines, yielding greater than the sum in their components; the regular improve of digital know-how, as characterised famously by way of "Moore's Law"; and the human-machine interface. Ceruzzi publications us via computing historical past, telling how a Bell Labs mathematician coined the observe "digital" in 1942 (to describe a high-speed approach to calculating utilized in anti-aircraft devices), and recounting the improvement of the punch card (for use within the 1890 U. S. Census). He describes the ENIAC, outfitted for clinical and army functions; the UNIVAC, the 1st basic goal desktop; and ARPANET, the Internet's precursor. Ceruzzi's account strains the world-changing evolution of the pc from a room-size ensemble of equipment to a "minicomputer" to a computing device computing device to a pocket-sized shrewdpermanent mobilephone. He describes the improvement of the silicon chip, which can shop ever-increasing quantities of information and enabled ever-decreasing equipment dimension. He visits that hotbed of innovation, Silicon Valley, and brings the tale as much as the current with the net, the area large internet, and social networking.

En réduisant le nombre de disques actifs en même temps, il est possible de réduire sensiblement les couts liés au contrôleur de disque. L’écriture et la lecture de données se font à grande vitesse puisqu’on agit en parallèle sur toutes les unités RAID1: Les données sont écrites de façon redondante et en même temps sur deux disques en miroir afin de préserver les données en cas de panne physique RAID3:Cette technique utilise plusieurs disques pour répartir les données à la manière RAID 0 et un disque supplémentaire pour stocker les bits de parités.
Souvent utilisé pour implémenter des sauvegardes sans serveur.
Serveurs redondants • Conserver un ordinateur inactif redondant disponible pour la récupération des défaillances - - tolérances aux pannes de serveur • Fournir un ou plusieurs systèmes complets disponibles au cas où le système principal tombe en panne. Mise en grappe (Clustering) Semblable aux serveurs redondants, hormis que tous les systèmes participent au • traitement des demandes de service. • La grappe(cluster) agit comme une unité intelligente unique pour équilibrer la charge de trafic. • Plus intéressant que la solution de redondance serveur, car les systèmes secondaires fournissent effectivement du temps de traitement.
