Data communication. Data communication, including data transmission and data reception, is the transfer of data, transmitted and received over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication using radio spectrum, storage media and computer buses.
IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association . It is concerned with: [1] 802 LAN / MAN architecture. internetworking among 802 LANs, MANs and wide area networks. 802 Link Security. 802 overall network management. protocol layers above the MAC and LLC layers.
The Internet Protocol ( IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet . IP has the task of delivering packets from the source host to the destination host solely based on the ...
1. Physical layer. v. t. e. The Open Systems Interconnection ( OSI) model is a reference model from the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection." [2] In the OSI reference model, the communications between systems ...
In computer network engineering, an Internet Standard is a normative specification of a technology or methodology applicable to the Internet. Internet Standards are created and published by the Internet Engineering Task Force (IETF). They allow interoperation of hardware and software from different sources which allows internets to function. [1]
RFC (s) RFC 9293. The Transmission Control Protocol ( TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery ...
In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data. It formally defines signals connecting between a DTE ( data terminal equipment) such as a computer terminal or PC, and a DCE ( data circuit-terminating equipment or data communication ...
Getting the data across a network is only part of the problem for a protocol. The data received has to be evaluated in the context of the progress of the conversation, so a protocol must include rules describing the context. These kinds of rules are said to express the syntax of the communication. Other rules determine whether the data is ...
