¿Cuáles son los tres tipos de protocolos de comunicación?

What are the three types of communication protocols?

Types of Communications Internet Protocols (IP)

• Transmission Control Protocol (TCP) – used for data transmission.
• User Datagram Protocol (UDP) – used by programs to send short datagram messages.
• Internet Control Message Protocol (ICMP) – messages used for diagnostic or error-generating purposes.

A communications protocol is a set of formal rules describing how to transmit or exchange data, especially across a network. Examples of standardised communications protocols include WiFi, the Internet Protocol, and the Hypertext Transfer Protocol (HTTP).

It is used to explain data format that is needed to be sent or received. It is used to explain exact meaning of each of sections of bits that are usually transferred.

There are three main types of network protocols. These include network management protocols, network communication protocols and network security protocols: Communication protocols include basic data communication tools like TCP/IP and HTTP.

A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods.

A protocol is a set of rules that govern data communications. It defines what is communicated, how it is communicated, and when it is communicated. The key elements of a protocol are syntax, semantics, and timing.

Communication protocols allow different network devices to communicate with each other. They are used in both analog and digital communications and can be used for important processes, ranging from transferring files between devices to accessing the internet.

Networks are set up with a protocol hierarchy that divides the communication task into several layers. A protocol is a set of rules for communication within a layer. A service is what the layer provides to the layer above it through an interface. Protocols at one layer are unaware of issues at another layer.

A protocol is a set of step-by-step guidelines—usually in the form of a simple one- or two-page document—that is used by educators to structure professional conversations or learning experiences to ensure that meeting, planning, or group-collaboration time is used efficiently, purposefully, and productively.

2.2 THE FIVE ELEMENTS OF A PROTOCOL

• The service to be provided by the protocol.
• The assumptions about the environment in which the protocol is executed.
• The vocabulary of messages used to implement the protocol.
• The encoding (format) of each message in the vocabulary.

A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. Communicating systems use well-defined formats for exchanging various messages.

There is no reference of hierarchical communication protocol anywhere! At another place, I saw that the entire network is divided into zones, like clusters and different protocols are used inside and outside the clusters. That was called something hierarchical as well!

Between each adjacent layer is an interface that defines the services that are being offered by a lower layer to the next higher layer. The dotted arrows depict virtual communication between peer layers, while the solid arrows represent the physical communications between the adjacent layers.

Protocol Hierarchies Most networks are organized as a stack of layers, one on the top of another. The number of layers and their names vary from network to network. Each layer has a specified function and adheres to specified protocols.

Hierarchical routing is a method of routing in networks that is based on hierarchical addressing . Most Transmission Control Protocol / Internet Protocol ( TCP/IP) routing is based on a two-level hierarchical routing in which an IP address is divided into a network portion and a host portion.
