WebIn telecommunications, a protocol data unit (PDU) is a single unit of information transmitted among peer entities of a computer network.It is composed of protocol-specific control information and user data.In the layered architectures of communication protocol stacks, each layer implements protocols tailored to the specific type or mode of data …

WebLa Protocol Data Unit ou Unité de données de protocole (PDU) est l'unité de mesure [1] des informations échangées dans un réseau informatique. Exemple en OSI. Appliqué au système de couches du modèle OSI, le PDU : de la couche physique est le bit ; de la couche liaison est ...

WebApplication Protocol Data Unit (APDU; englisch für „Datenelement des Anwendungsprotokolls“) bezeichnet einen kombinierten Kommando-/Datenblock des Kommunikationsprotokolls zwischen einem Chipkartenleser und einer Chipkarte.Für den Datenaustausch wird ein kombinierter Befehls- (oder Kommando-) und Datenblock …

WebThe Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks.The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails.. As the name …

Web電気通信において、protocol data unit（PDU、プロトコルデータユニット）とは、コンピュータネットワークのピアエンティティ（両端）の間で送受信される最小の情報の単位である。. PDUは、通信プロトコルで定義された制御情報（ヘッダ）部分と、通信データの中身であるペイロードからなる。

WebInternet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deployed for production on SATNET in 1982 and on the ARPANET in January 1983. It is still used to route most Internet traffic …

WebThe Lightweight Directory Access Protocol (LDAP / ˈ ɛ l d æ p /) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing …

WebThe Internet Protocol is responsible for addressing host interfaces, encapsulating data into datagrams (including fragmentation and reassembly) and routing datagrams from a source host interface to a destination host interface across one or more IP networks. For these purposes, the Internet Protocol defines the format of packets and provides an …

WebIn computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. It can provide loop connection authentication, transmission encryption, and data compression.. PPP is used over many types of physical networks, …

WebEthernet (/ ˈ iː θ ər n ɛ t /) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3.Ethernet has since been refined to support higher bit rates, a greater number …
