cAdvisor, short for Container Advisor, is a daemon that gathers information about running containers and provides users with insights into their resource usage and performance characteristics. It collects and processes data such as resource isolation parameters, historical usage, histograms, and network statistics for each container, and exports this data by container and machine-wide. external-link

According to the ART4DCM-86 - DCM standard, the capacity of a supplier is defined in several ways. The "supplier capacity" refers to the amount of output that a supplier can realistically produce per calendar week and material for a particular customer, taking into account all factors that may affect this capacity. The "supplier maximum capacity," on the other hand, is the absolute maximum amount of output that a supplier can produce per calendar week and material for a specific customer. The difference between the supplier's maximum capacity and their actual capacity is known as the "supplier flex capacity," which represents the amount of flexible capacity that a supplier has available. Finally, the "contractual capacity" is the capacity that is agreed upon in a contract between the supplier and the customer for a specific period, typically converted to a weekly basis. external-link

Capital expenditure

CAPEX, which stands for "capital expenditures," is an abbreviation used to describe investment spending on long-term assets such as machinery, buildings, initial equipment, replacement parts, and computer systems, among others. CAPEX is a crucial metric for a company's balance sheet. These expenditures increase the capitalized assets, which are depreciated over the long term. external-link

Designates the category of a cable made of twisted copper wires for data transmission. Today, CAT-5 cables for frequencies up to 100 MHz are predominantly encountered. Together with the RJ-45 connectors, they make up the common Ethernet cables. external-link

Central data hub

Assuming it is legally allowed across different jurisdictions, a central data hub obtains subscriptions to and combines data from multiple data lakes.

Data Intelligence Hub

Central Processing Unit

The CPU, or Central Processing Unit, is the primary component of a computer. It is a microprocessor that monitors and manages all computing operations of the computer, stores results and intermediate results, and holds necessary data for computing operations. The CPU is responsible for executing data transfers as well as logical and arithmetic operations. external-link


Certificates are files used to ensure secure access to the Kubernetes cluster. They enable applications in the cluster to securely access the Kubernetes API, verifying that clients have authorization to do so. external-link

Certification Authority (CA)

A party with the authority to generate, validate, distribute, and invalidate certificates for public keys. external-link

Certification Body

The organization in charge of certifying components and entities that wish to join the International Data Spaces not only has the authority to approve or reject certification, but also bears the responsibility of managing the Certification Scheme, which includes a list of criteria, and supervising and endorsing Evaluation Facilities. Additionally, this organization must guarantee that the evaluation procedures conducted by these facilities are compatible. external-link

Certification of trustworthy AI

Numerous ongoing projects are dedicated to creating a framework and catalogue that can be used to audit the trustworthiness of AI applications. The primary objective of this initiative is to establish measurable criteria for adherence to ethical principles such as human autonomy and control, fairness, privacy, and transparency, as well as security and safety. external-link

Generally, the CTO directly reports to the Chief Executive Officer (CEO) of the company. external-link


CIDR stands for Classless Inter-Domain Routing, which is a way of describing blocks of IP addresses in networking. In Kubernetes, each Node is assigned a range of IP addresses through CIDR notation, which consists of a start address and a subnet mask. This enables Nodes to assign each Pod a unique IP address. While CIDR was originally used for IPv4, it has also been expanded to include IPv6. external-link

Circuit Switched Data

The CSD service (Circuit Switched Data) is a data transmission service available in GSM networks. This service operates on a circuit-switched network at a rate of 9.6 kbit/s and is distinguished by its low bit error rate, which is achieved through the use of special radio protocols and advanced error correction techniques. A flawless radio connection between the mobile phone or radio modem and the base station is essential for the CSD service to function without errors. Faulty radio connections can reduce the relatively low data rate and increase the likelihood of errors. external-link

Circular economy

The circular economy model encompasses practices such as sharing, leasing, reusing, repairing, refurbishing, and recycling of already existing materials and products, with the objective of extending the life cycle of these products. external-link


City hubs serve as central points for supplying retail and industrial companies in urban areas and are not dependent on freight forwarders or logistics service providers.
