Term Definition
C ListSCSI Storage products. SCSI Term. This list shows the positions of defects detected during the initialised data block verification of the FORMAT UNIT command. This list is generated internally by the IDD during execution of the FORMAT UNIT command.
 
Carrier-To-Noise Ratio (CNR)Storage products. The ratio of the root-mean-square (RMS) power of a signal at a specified frequency to the RMS power of the noise in a specified bandwidth, expressed in decibels (dB).
 
CAT5Category 5 cable is constructed using eight 24 AWG insulated conductors (four pairs), enclosed by a thermoplastic jacket.  Each of the four conductor pairs is twisted together at a slightly balanced high-speed communications circuit and to reject electrical interference or "noise" from sources such as power wiring, fluorescent and HID ballasts, motors, and so on.
 
CataloguingThe process of arrangement and description of archives to produce a structured list or catalogue, usually prefaced with an-outline history of the documents and their originator/s, which enables users to locate the documents they need.
 
CD-RStorage products. Compact Disc-Recordable.
 
Check-inTo store an item in the system that has been previously checked-out. The checked-in item may be a new issue (that is, a complete, approved item), or an iterim version (for example, an incomplete, unapproved version checked-in before going on holiday).
 
Check-outTo take a copy of a version of an item from the system with the explicit intent to modify it and create a new version.
 
ChromalinPrinters / Scanners. An off-press colour proofing system developed by DuPont. The proofs are single laminated sheets produced from film separations.
 
ClassificationThe process of devising and applying schemes based on the business activities which generate records, whereby they are categorised in systematic and consistent ways to facilitate their capture, retrieval, maintenance and disposal. Classification includes determining document or file naming conventions, user permissions and security restrictions on records. Australian Standard AS 4390-1996, Part 1. Clause 4.8.
 
Classified InformationInformation classified as Confidential, Registered, Private, or Privileged. Business Units may have additional classifications.
 
Closed Loop Servo SystemStorage products. A correction system in the form of a loop that has no exit, exchanging information about changes in the constitution of the storage medium (e.g. temperature-related expansion) and of the drive mechanics in a feedback method between a reference track on the medium and the head positioning. In this way, irregularities may be corrected more easily, which is of advantage for data integrity and which, particularly with smaller drives, renders higher data densities secure. This feedback technology is frequently accompanied by the use of linear or rotary voice coil actuator technology.
 
CMS (i)Printers / Scanners. Colour management system. This ensures colour uniformity across input and output devices so that final printed results match originals. The characteristics or profiles of devices are normally established by reference to standard 1T8 colour targets.
 
CMS (ii)
Content Management System.  A system used to organize and facilitate collaborative creation of documents and other content. A CMS is frequently a web application used for managing websites and web content, though in many cases, content management systems require special client software for editing and constructing articles.

 
CMYKPrinters / Scanners. Cyan, Magenta, Yellow, Black. The subtractive primaries, or process colours, used in colour printing. Black (K) is usually added to enhance colour and to print a true black.
 
COLDComputer Output to Laser Disk. The storage of data on optical disk, such as CD-ROMs. Storing large volumes of data on laser disk, as opposed to microfiche or microfilm, lets the user access and search this information on a computer, avoid the duplication and security costs of protecting physical documents or film, and more readily distribute information
 
Colour CastPrinters / Scanners. An overall colour imbalance in an image, as if viewed through a coloured filter
 
Colour CorrectionScanners. The process of adjusting an image to compensate for scanner deficiencies or for the characteristics of the output device.
 
Colour ProofScanners. A representation of what the final printed composition will look like. The resolution and quality of different types of colour proofs can vary greatly.
 
Colour SeparationPrinters / Scanners. The division of an image into its component colours for printing. Each colour separation is a piece of negative or positive film.
 
Colour SpaceScanners. Three-dimensional model (or representation of a 3D model) used to organize colours to show progressions of hue, lightness, and saturation. Device-independent colour spaces are based on international standards (CIE).
 
ColourimeterScanners. A light-sensitive device for measuring colours by filtering their red, green and blue components, as in the human eye.
 
Competitive advantageA widely-used term in the private sector to describe something that differentiates a company from its competitors in the same industry and makes it more likely to gain profits than the others.
 
ComponentAny digital file. This definition uses the term “file” in the IT sense, meaning “a collection of related data stored as a unit with a single name” rather than in the records management sense.
 
Composite HeadHard Disk. The composite head is composed primarily of a ferrite core with a wire coil and a glass-filled gap, and the material used to bond the core to the slider. Ferrite is a hard material which makes it difficult to meet today's physical and electrical characteristics required for higher areal densities. Conventional ferrite heads, such as this, have reached the limits of their performance with regard to the machining processes and magnetic characteristics in the high-frequency domain.
 
Composite itemA single item that includes (via an application`s linking mechanism) one or more other items that exist separately in the System. For example, a single Word file that includes (via Word`s file linking mechanism) a number of chapters that each exist as a separate Word file stored elsewhere in the System.
 
Compound Document ManagementCompound documents can be created from multiple content sources. The relationship and configuration of the com[pound document is managed and multiple levels of nesting are provided. The ability to link specific versions of component documents is provided through a graphic interface.
 
CompressionScanners. Encoding the bits of information in an image file so that it takes up less space when stored. Compression results in little or no distortion. See also lossy and non-lossy.
 
ComputerGeneral computing. A programmable machine.
 
ConfidentialityThe service that protects information from knowledge or disclosure. Encryption is an example of Confidentiality.
 
Configuration ManagementAll those activities focused on the registration, management and availability of the IT components and the relation between them, belonging to the computer platform on which the digital archive runs.
 
Constant Density RecordingStorage products. In this technique, data is recorded at a density approximately constant on all tracks therefore, outer tracks have a larger capacity and higher data transfer rate. In conventional recording, the track capacity is based on the innermost track.
 
Content management'Content' in this context generally refers to computer-based information such as the content of a website or a database. Content management is about making sure that content is relevant, up-to-date, accurate, easily accessible, well organised etc, so that quality information is delivered to the user.
 
ContextSynonym of provenance.
 
Continuous-TonePrinters / Scanners. Image that has a complete range of tones from black to white: photographs, paintings and drawings. Negative or positive with a broad range of tones that have no screened dots
 
Controlled languageA thesaurus of permitted terminology used to ensure consistency of indexing, either manual or electronic, to facilitate searching by providing the user with a list of preferred terms.
 
ConversionProcess of changing records from one medium to another or from one format to another.
 
CRCGeneral computing. Cyclic Redundancy Check : frequently used error-checking (correctness of memory contents) in the read/write head zone.
 
Critical Information and SystemsInformation, applications, and infrastructure that have direct impact on business operations and activities.  Damage, data corruption, theft of information, or prolonged unavailability would cause significant damage to the organisation. 
 
Cross Talk LevelStorage products. The ratio of the level of a spurious signal generated by an adjacent track to the level of the signal of that adjacent track.
 
CryptographyCoding the contents of a message to prevent unauthorised access.
 
CSMA/CDNetworking. Carrier-Sense Multiple Access with Collision Detection. Media access method used in Ethernet networks. When an Ethernet card needs to send data, it first checks to see if the media is free. If the media is free the data is sent. If another station on the network transmits at the same, the card backs off for a random period of time. The card then repeats the process in order to retransmit the data.
 
Curie PointOptical. The temperature at which the polarity of a magnetic material is easily changed. Normally associated with optical disk technology.
 
Curie TemperatureOptical. The temperature above which a magnetic material loses its magnetic properties and can be easily magnetised by an applied magnetic field.
 
Customer relationship managementA business strategy based on selecting and proactively managing the most valuable customer relationships. It requires a customer-focused philosophy to support effective marketing, sales and customer service processes.
