Glossary

Name

In Kubernetes, a name is a user-defined string that identifies a specific object in a resource URL, for example, /api/v1/pods/some-name. Each object of a certain kind should have a unique name within its namespace. However, if you delete an object, you can create another object with the same name.

Namespace

In order to support the isolation of the different resource groups withing the individual clusters the Namespace abstract is used. Namespaces facilitate organizing objects in a cluster and dividing cluster resources.Resource names need to be unique within a namespace, but not across namespaces. Namespace-based scoping is applicable only for namespaced objects (e.g. Deployments, Services, etc) and not for cluster-wide objects (e.g. StorageClass, Nodes, PersistentVolumes, etc).

NAMUR

This is a user association with a global membership that focuses on automation technology and digitalization in process industries.

NAT-44

The automatic translation of an IPv4 address to another IPv4 address is called NAT-44.

NAT-64

The automatic translation of IPv6 addresses into IPv4 addresses is called NAT64. By using NAT64, it is possible to enable communication between IPv6 and IPv4 networks.

Near Field Communication

Near Field Communication" wireless technology enables the contactless exchange of data between devices at extremely short distances of just a few centimeters.

Network Address Translation

When connecting different networks, the automatic translation of addresses in data packets is called Network Address Translation.

Network Analytics

Network analysis involves deconstructing the data of a complicated project into its constituent parts, including activities, events, durations, and more, and then graphically displaying them to reveal their interdependencies and connections.

Network Bandwidth (in Gbps)

Maximum rate of data transfer for peer-2-peer data exchange, possibly shared among multiple users.

Network Filesystem

NFS, or Network File System, is a type of client/server software that allows a user to access and manipulate files on a remote computer as if they were on their own local computer. The user's computer must have an NFS client installed, while the remote computer must have an NFS server running.

Network Function Virtualization

NFV, an idea put forward by a community of interest situated in ETSI, aims to define network functions such as gateways, routers, application servers, etc., which have conventionally been a product of software and dedicated hardware, in such a way that they can operate as software-only solutions on standard IT servers.

Network of stakeholders

The network of stakeholders associated with the development of dataspaces, whom the Data Spaces Support Centre interacts with, includes a broad range of organizations such as various industry players, associations, related projects, standardization bodies, regulators, and digital innovation hubs. This Community of Practice, which is a subset of the larger stakeholder network, represents the primary focus group for the Data Spaces Support Centre.

Network Policy

Network Policies define the guidelines for communication between groups of Pods and other network endpoints. By using labels, Network Policies enable the selection of Pods and the creation of rules that specify which traffic is allowed to reach the selected Pods. These rules can be used to configure connectivity between Pods, namespaces, and port numbers. It is essential to note that Network Policies are executed by a network plugin supplied by a network provider. Without a controller to implement them, creating a network resource will not be effective.

Networked Learning

Networked Learning is a term used to describe the process of utilizing the internet to develop or provide access to information and individuals in order to support one's own educational, learning, and qualification goals.

New SQL

NewSQL is a recently developed language used for accessing databases. It is defined in a clear, concise, and consistent manner and is considered more user-friendly than SQL. It should be noted that it is not a subset or an extension of SQL, nor is it an object-oriented database language. Instead, it is built on top of the cross-database library LDBC.

Next Generation Access

The term "next generation access" refers to next-generation access networks that enable high bit rates. These networks can either consist of fiber-optic lines with a minimum speed of 40 Mbit/s downstream and 15 Mbit/s upstream, or a cable network with a speed of up to 50 Mbit/s or more. In addition, new office and residential buildings can be connected via a fiber-optic cable network with speeds of up to 100 Mbit/s, as specified in the EU Broadband Expansion Guideline of September 2010.

NIS-Directive

The Directive (EU) 2016/1148 aims to establish a high, consistent level of security for network and information systems across the European Union. For further information, please refer to the following link: https://eurlex.europa.eu/legal-content/EN/TXT/?uri=uriserv:OJ.L_.2016.194.01.0001.01.ENG&toc=OJ:L:2016:194:TOC.

Node-pressure eviction

Node-pressure eviction is a method employed by kubelet to free up resources on nodes by proactively terminating pods. The kubelet continuously monitors various resources such as CPU, memory, disk space, and filesystem inodes on the nodes of your cluster. If the consumption of any of these resources reaches a certain threshold, the kubelet can take action by terminating one or more pods on the node to reclaim resources and prevent resource starvation. It is crucial to note that node-pressure eviction differs from API-initiated eviction.

Non-Disclosure Agreement

If founders are having important discussions with a venture capitalist, it may be wise to enter into a Non-Disclosure Agreement (NDA). The NDA allows the parties to exchange confidential business information without fear of that information being misused. The founders have a legitimate interest in protecting this information, and with an NDA, all parties commit to treating the information confidentially.

Non-Relational Database

A database that doesn't follow the table/key model promoted by relational database management systems (RDBMS) is referred to as a non-relational database. Manipulating data in these databases requires specific techniques and processes to address big data challenges encountered by large companies.

NoSQL Databases

The term NoSQL refers to a database technology that does not follow the architecture of relational databases and therefore does not require fixed table schemas. The focus is on improved horizontal scalability of the database. NoSQL databases are particularly preferred in the web environment, where large amounts of data often accumulate that need to be processed.

Notary

An entity recognized by Gaia-X that translates a Trusted Data Source into verifiable credentials on behalf of the entity managing the Trusted Data Source

Number of users

This specifies the maximum number of users who can use the portal (i.e., the management interface) and the Connector UI, not necessarily simultaneously. Please note that the use of additional services may be allowed for more users than specified here, depending on the configuration of the service itself.

Number Portability

In telecommunications, there is the option of number portability. This allows customers to keep their phone number when they switch providers and transfer it to the new provider's systems.
