Consumer Technology Association
The Consumer Technology Association (CTA), once the Consumer Electronics Association, is an American trade group headquartered in Arlington, Virginia, that owns and produces the CES trade show.
Consumers Energy
Consumers Energy is an investor-owned utility headquartered in Jackson, Michigan, founded in 1886 and serving 1.9 million electric and 1.8 million gas customers as the principal subsidiary of CMS Energy.
Contact engineering for 2D semiconductors
Contact engineering for 2D semiconductors is the set of materials and process strategies used to form low-resistance electrical contacts to atomically thin semiconductors such as MoS₂.
Contact force distribution optimization
Contact force distribution optimization, known as the force distribution problem, is the robotics problem of splitting a robot's required contact wrench among feet and hands under friction limits.
Contact force model
A contact force model is a mathematical law computing the normal and friction forces when two bodies touch, collide, or roll in a multibody simulation, using compliant or rigid formulations.
Contact lithography
Contact lithography is a photolithography technique in which a photomask is pressed into direct contact with the wafer so ultraviolet light transfers the pattern; mask damage limits it to MEMS and low-volume work.
Contact print
A contact print (contact printing) is a photographic image made by exposing light-sensitive paper in direct contact with the negative, so the print matches the negative's size exactly.
Contact ratio
The contact ratio of a gear pair is the average number of tooth pairs in contact as the gears mesh, typically between 1 and 2.
Contact wrench estimation
Contact wrench estimation is the inference of the six-dimensional force-and-moment wrench exchanged between a robot and its environment at a contact, using force/torque sensors, proprioception, and dynamics models.
Contact-implicit model predictive control
Contact-implicit model predictive control (CI-MPC) is a control method in which a robot's receding-horizon optimizer discovers when and how to make contact, rather than following a pre-specified schedule.
Contactless smart card
A contactless smart card is an ID card with a chip that talks to a reader by radio at 13.56 MHz, powering itself from the reader's field.
Contactor
A contactor, or electrical contactor, is an electromechanical switch that uses a low-power control signal to repeatedly switch high-current loads such as motors and heaters.
Container
A container is a reusable food-storage vessel with a lid, made of glass, plastic, metal, or silicone, that preserves food in the refrigerator, freezer, or pantry.
Container Corporation of India
Container Corporation of India, commonly known as CONCOR, is an Indian public sector logistics company under the Ministry of Railways, incorporated in 1988 and operating nationwide container terminals.
Container crane
A container crane is a large dockside gantry machine that transfers intermodal containers between ship and quay; the first purpose-built crane entered service in Alameda, California in 1959.
Container ship
A container ship, also called a container vessel or boxship, is a cargo ship carrying standardized intermodal containers, pioneered by the Ideal X voyage in 1956.
containerd
containerd is an open source container runtime, born at Docker and donated to the CNCF in 2017, that manages the full container lifecycle on Linux and Windows.
Containerization
Containerization is a freight transport system that loads goods into standard steel containers moved between ships, trucks, and trains, beginning with Malcolm McLean's 1956 voyage.
Containment building
A containment building is the strong, essentially leak-tight structure that surrounds a nuclear power reactor to prevent or control the release of radioactive substances to the environment, typically of thick concrete and steel.
Contemporary architecture
Contemporary architecture is the architecture of the 21st century, a period label rather than a single style, distinct from modern architecture, a historical movement of the 1920s to 1970s.
Content Authenticity Initiative
The Content Authenticity Initiative is a cross-industry community founded by Adobe in 2019 that promotes media transparency through Content Credentials, signed provenance metadata for digital images, video, and audio.
Content delivery network
A content delivery network (CDN), also called a content distribution network, is a distributed group of servers that caches web content close to users to speed delivery.
Content management system
A content management system (CMS) is software that helps users create, manage, and modify digital content without hand-coding pages, with WordPress, Drupal, and Contentful as examples.
Content negotiation
Content negotiation is the HTTP mechanism by which a client and server agree on which representation of a resource to deliver, such as media type, language, or encoding.
Content Security Policy
Content Security Policy (CSP) is a browser-enforced security mechanism that restricts which sources of scripts and other resources a web page may load, defending against cross-site scripting.
Content-addressable storage
Content-addressable storage is a storage paradigm that identifies data by a cryptographic hash of its content rather than by location or path, providing inherent deduplication and integrity checking.
Content-based filtering
Content-based filtering is a recommendation method that matches item features, such as text, tags, or genres, against a profile of one user's past preferences, unlike collaborative filtering.
Content-based image retrieval
Content-based image retrieval (CBIR) is a computer vision technique that finds database images similar to a query image using visual features like color, texture, and shape.
Content-centric networking
Content-centric networking (CCN) is a communications architecture proposed by Van Jacobson in 2006 in which requests name content, and any node holding it can respond.
Contention window
A contention window (CW) is the range of slot times from which a wireless station draws a random backoff before transmitting in CSMA/CA, doubling after collisions.
