Why do we need protocol architecture

Provides ccess to the TCP/IP environment for users and also provides distributed information services. Transfer of data between end points. May provide error control, flow control, congestion control, reliable delivery. Shield higher layers from details of physical network configuration.

Why do we need protocols?

Protocols are basically needed because it’s important for the receiver to UNDRSTAND the sender. In computer communications, protocols also make sure the message gets to its destination properly, in entirety, and with out distortion. Answer: … Protocols are simply rules for communication.

What is protocol and its architecture?

In a protocol architecture, the modules are arranged in a vertical stack, each layer in the stack performs a related subset of the functions. It relies on the next lower layer to perform more primitive functions. It provides services to the next higher layer.

Why do we need layered protocol architecture?

The main aim of the layered architecture is to divide the design into small pieces. Each lower layer adds its services to the higher layer to provide a full set of services to manage communications and run the applications. It provides modularity and clear interfaces, i.e., provides interaction between subsystems.

What is the need for protocol architecture in digital communication system?

Provides ccess to the TCP/IP environment for users and also provides distributed information services. Transfer of data between end points. May provide error control, flow control, congestion control, reliable delivery. Shield higher layers from details of physical network configuration.

What is the purpose of protocols in data communication?

What is the purpose of protocols in data communications? Protocols provide rules that define how a message is transmitted across a network. Implementation requirements such as electronic and bandwidth details for data communication are specified by standards.

What is the importance of protocol in diplomacy?

In fact, the rules and processes of diplomatic protocol are based in pragmatic thinking, common sense and good manners.” Protocol, the trainers suggest, is important precisely because it “makes the job of representing our nation easier by facilitating our work as a mission team, making our relationships and

What is protocol in simple words?

noun. pro·​to·​col | \ ˈprō-tə-ˌkȯl , -ˌkōl, -ˌkäl, -kəl \ Essential Meaning of protocol. 1 : a system of rules that explain the correct conduct and procedures to be followed in formal situations The soldier’s actions constitute a breach of military protocol.

What are the key elements of protocol?

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.

Why do we need layered protocol for data transmission in a network?

Layers provide a division of the work done by a network. 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.

What is protocol suite in networking?

The Internet protocol suite, commonly known as TCP/IP, is the set of communications protocols used in the Internet and similar computer networks. The current foundational protocols in the suite are the Transmission Control Protocol (TCP) and the Internet Protocol (IP).

What is ATM protocol architecture?

The asynchronous transfer mode (ATM) protocol architecture is designed to support the transfer of data with a range of guarantees for quality of service. The user data is divided into small, fixed-length packets, called cells, and transported over virtual connections.

What is an example of a protocol?

A protocol is a standard set of rules that allow electronic devices to communicate with each other. … Examples include wired networking (e.g., Ethernet), wireless networking (e.g., 802.11ac), and Internet communication (e.g., IP).

How can protocol be applied to communication through Organisational structures?

A communication protocol is a formal process that outlines the types of information to be communicated to an organization, as well as identifying the person(s) responsible for communicating particular topics. The protocol also outlines the audience, frequency, and suggested communication vehicles.

What is the advantage of using standards to develop and implement protocols?

Different manufacturers are free to apply different requirements when implementing a protocol. Standards provide flexibility for manufacturers to create devices that comply with unique requirements. Explanation:Standards-based protocols enable products from different manufacturers to interoperate successfully.

What are standards and protocols?

A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it.

What is the principle of protocol?

Principle – “a moral rule or belief that helps you know what is right and wrong and that influences your actions.” Protocol – “a system of rules that explain the correct conduct and procedures to be followed in formal situations.”

What does safety protocol mean?

A written safety protocol, also known as a “Standard Operating Procedure”, is required by the OSHA Laboratory Standard. It is a document that includes the safety requirements developed in the risk assessment.

What is the meaning of protocol observed?

: (VSD) ‘Protocols’ are a system of ‘rules’, customs and observances which can govern any sort of activity, so if ‘all protocols are observed’ it means the speaker or writer is claiming that the relevant niceties have been followed.

What protocol is needed for Internet connection?

Common Internet protocols include TCP/IP (Transmission Control Protocol/Internet Protocol), UDP/IP (User Datagram Protocol/Internet Protocol), HTTP (HyperText Transfer Protocol) and FTP (File Transfer Protocol).

What is a protocol suite and what is the advantage of a suite?

What is a protocol suite, and what is the advantage of a suite? It is a completely, cooperative set of protocols. Each protocol in a suite handles one aspect of communication; together, the protocols in a suite cover all aspects of communication, including hardware failures and other exceptional conditions.

How many protocols are used in the application layer *?

How many protocols are used in the application layer? Explanation: More than 15 protocols are used in the application layer, including file transfer protocol, Telnet, Trivial File Transfer Protocol and simple network Management Protocol. 5.

Why ATM is called asynchronous?

Asynchronous, in the context of ATM, means that sources are not limited to sending data during a set time slot, which is the case with circuit switching, used in the old standby T1. ATM transmits data not in bits or frames, but in packets. … In short, data is sent asynchronously and cells are sent synchronously.

Why is padding necessary for ATM?

Each AAL5 packet is divided into an integral number of ATM cells and reassembled into a packet before delivery to the receiving host. … The last cell contains padding to ensure that the entire packet is a multiple of 48 octets long.

What are the main attractive features of ATM technology?

  • Interface types. The interface between ATM switches is called a Network to Network Interface (NNI). …
  • Switch types. ATM switches come in a variety of types and sizes. …
  • Attached devices. …
  • Link speeds. …
  • Attach media.
