Chapter 2: Protocol
A Network Protocol is a group of rules accompanied by the network. Network protocols will be formalized requirements and plans composed of rules, procedures, and types that describe communication among a couple of devices over the network. The protocol can be described as an approach to rules that enable a couple of entities of a communication program to transfer information through any type of variety of a physical medium. The protocol identifies the rules, syntax, semantics as well as, synchronization of communication as well as, feasible error managing methods. In this article, we will discuss the different types of networking protocols. There are two common network protocols used to send data packets over a network.
Types of Internet Protocols
The functions of protocols are quite essential in the process of Networking. There are a number of protocols which exist and are used for various purposes. In fact, each of the protocol has been developed keeping in mind a particular situation or problem. Sometimes more than one protocols work together to achieve their task. However, just an overview of these protocols is not necessary to manage the process of networking. It is important that these protocols are known in depth and the user has an understanding of them. The use of protocols is quite essential in almost every layer of the OSI Model, especially from the Transport layer till the Application layer.
-SNMP (Simple Network Management Protocol) allows the management of the network. FTP. Telnet. SNMP. SMTP. TCP/UDP. IP. Ethernet. Arpanet.
Types of Network Protocols Explained with Functions
In the era of Computer and Mobile technologies, computer network technology is growing at a very fast speed and frequency. Billions of electronic devices and gadgets are operating to make this happen. These devices are designed and manufactured by different manufacturers. They may have been developed using different hardware and software resources.
A protocol is a set of rules that governs the communications between computers on a network. In order for two computers to talk to each other, they must be speaking the same language. Many different types of network protocols and standards are required to ensure that your computer no matter which operating system, network card, or application you are using can communicate with another computer located on the next desk or half-way around the world. The complexity of these layers is beyond the scope of this tutorial; however, they can be simplified into four layers to help identify some of the protocols with which you should be familiar see fig 1. Figure 1 illustrates how some of the major protocols would correlate to the OSI model in order to communicate via the Internet. In this model, there are four layers, including:.
A communication protocol is a system of rules that allow 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. Protocols may be implemented by hardware , software , or a combination of both.
Protocol, TCP, and the User Datagram Protocol, UDP, offering different types of consists of two computers, where their roles or the functions are not articulated.
It is the foundation of any data exchange on the Web and it is a client-server protocol, which means requests are initiated by the recipient, usually the Web browser. A complete document is reconstructed from the different sub-documents fetched, for instance text, layout description, images, videos, scripts, and more. Clients and servers communicate by exchanging individual messages as opposed to a stream of data. The messages sent by the client, usually a Web browser, are called requests and the messages sent by the server as an answer are called responses. Designed in the early s, HTTP is an extensible protocol which has evolved over time. It is an application layer protocol that is sent over TCP , or over a TLS -encrypted TCP connection, though any reliable transport protocol could theoretically be used.
A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network.
