Chapter 1 — Introduction to the Matter communication standard
Matter technology is one of the types of Internet of Things (IoT) standards in order to improve the connectivity and cooperation of smart devices from different brands in the market. Matter works through Wi-Fi and Thread; In this way, it allows smart home devices to communicate with each other with Wi-Fi, and on the other hand, Thread provides an efficient mesh network with high reliability in homes.

In the rest of this chapter, the tables related to the abbreviations, definitions and correspondence of the specialized terms used in the Matter standard are given; Here we are going to examine some of these technical terms that seem more applicable. Therefore, to get more information and study all these terms, it is necessary to refer to the comprehensive technical specification document of the Matter standard.

Definition of some terms | ||
Definition | Term | Row |
A data entity which represents a physical quantity or state. This data is communicated to other Nodes using commands. | Attribute | 1 |
A persistent attachment between an instance on one Node to one-or-more corresponding instances on another (or the same) Node. | Binding | 2 |
A Node that represents one or more non-Matter devices on the Fabric. | Bridge | 3 |
To bring a Node into a Fabric. | Commission | 4 |
A 12-bit value used to discern between multiple commissionable Matter device advertisements. See Discriminator value. | Discriminator | 5 |
A particular component within a Node that is individually addressable. | Endpoint | 6 |
A logical collection of communicating Nodes, sharing a common root of trust, and a common distributed configuration state. | Fabric | 7 |
A system component which takes the NOCSR from a Commissioner and allocates an Operational Node ID that is unique to the Fabric, inserts this Operational Node ID as the DN into the NOC, and signs the NOC. | Key Center | 8 |
A set of nodes that have addressability, connectivity, and reachability to one another via Internet Protocol. | Network | 9 |
An addressable entity which supports the Matter protocol stack and (once Commissioned) has its own Operational Node ID and Node Operational credentials. A Device MAY host multiple Nodes. | Node | 10 |
A low-power IEEE 802.15.4-based IPv6 mesh networking technology (see Thread specification). | Thread | 11 |
