Data storageData storage is the recording (storing) of information (data) in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage. Recording may be accomplished with virtually any form of energy. Electronic data storage requires electrical power to store and retrieve data. Data storage in a digital, machine-readable medium is sometimes called digital data.
Mémoire (informatique)En informatique, la mémoire est un dispositif électronique numérique qui sert à stocker des données. La mémoire est un composant essentiel, présent dans tous les ordinateurs, les consoles de jeux, les GPS et de nombreux appareils électroniques. Les mémoires sont vendues sous forme de pièces détachées de matériel informatique, ou de composants électroniques. Les différences entre les pièces sont la forme, l'usage qui en est fait, la technologie utilisée, la capacité de stockage et le rapport entre le coût et la capacité.
Communication animaleLa communication animale regroupe l'ensemble des échanges d'information entre des individus d'une même espèce (communication intraspécifique) ou d'espèces différentes (communication extraspécifique) chez les animaux. Les animaux communiquent entre eux pour différentes raisons : séduction du partenaire, compétition pour les ressources, recherche de nourriture. Ils utilisent pour cela un signal ou un message (support physique de l'information), comme une odeur, un son, un mouvement, ou un signal électrique.
Models of communicationModels of communication are simplified representations of the process of communication. Most models try to describe both verbal and non-verbal communication and often understand it as an exchange of messages. Their function is to give a compact overview of the complex process of communication. This helps researchers formulate hypotheses, apply communication-related concepts to real-world cases, and test predictions. Despite their usefulness, many models are criticized based on the claim that they are too simple because they leave out essential aspects.
Construction managementConstruction management (CM) is a professional service that uses specialized, project management techniques and software to oversee the planning, design, construction and closeout of a project. The purpose of construction management is to control the quality of a project's scope, time / delivery and cost—sometimes referred to as a project management triangle or "triple constraints." CM is compatible with all project delivery systems, including design-bid-build, design-build, CM At-Risk and Public Private Partnerships.
DSL modemA digital subscriber line (DSL) modem is a device used to connect a computer or router to a telephone line which provides the digital subscriber line (DSL) service for connection to the Internet, which is often called DSL broadband. The modem connects to a single computer or router, through an Ethernet port, USB port, or is installed in a computer PCI slot. The more common DSL router is a standalone device that combines the function of a DSL modem and a router, and can connect multiple computers through multiple Ethernet ports or an integral wireless access point.
Disk storageDisk storage (also sometimes called drive storage) is a general category of storage mechanisms where data is recorded by various electronic, magnetic, optical, or mechanical changes to a surface layer of one or more rotating disks. A disk drive is a device implementing such a storage mechanism. Notable types are the hard disk drive (HDD) containing a non-removable disk, the floppy disk drive (FDD) and its removable floppy disk, and various optical disc drives (ODD) and associated optical disc media.
Modem câbleUn modem câble est un type de modem qui permet de se connecter à Internet en étant relié à un réseau de télévision par câble. Le modem-câble est bidirectionnel, il n’utilise qu’un seul câble coaxial pour les deux directions, aval pour les données du réseau vers l’utilisateur et amont pour les données de l’utilisateur vers le réseau. Le réseau peut être constitué uniquement de câbles coaxiaux ou être hybride fibre coaxial.
Construction engineeringConstruction engineering, also known as construction operations, is a professional subdiscipline of civil engineering that deals with the designing, planning, construction, and operations management of infrastructure such as roadways, tunnels, bridges, airports, railroads, facilities, buildings, dams, utilities and other projects. Construction engineers learn some of the design aspects similar to civil engineers as well as project management aspects.
Object storageObject storage (also known as object-based storage) is a computer data storage that manages data as objects, as opposed to other storage architectures like which manages data as a file hierarchy, and block storage which manages data as blocks within sectors and tracks. Each object typically includes the data itself, a variable amount of metadata, and a globally unique identifier. Object storage can be implemented at multiple levels, including the device level (object-storage device), the system level, and the interface level.
Réseau de stockage SANvignette|upright=1.5|Protocoles d'accès à un SAN. En informatique, un réseau de stockage, ou SAN (de l'anglais Storage Area Network), est un réseau spécialisé permettant de mutualiser des ressources de stockage. vignette|Différence entre SAN et NAS. Un réseau de stockage se différencie des autres systèmes de stockage tels que le NAS (Network attached storage) par un accès bas niveau aux disques. Pour simplifier, le trafic sur un SAN est très similaire aux principes utilisés pour l'utilisation des disques internes (ATA, SCSI).
Liste de corps d'étatCet article constitue une liste rassemblant selon les répartitions communément usitées les corps de métier dans le domaine du génie civil, communément désignés sous l'appellation collective de corps d'état. Il s'agit d'appellations couramment rencontrées dans les allotissements des marchés de travaux.
