Types of Network Protocols Explained with Functions

In the field of networking, the specialist area of Network Security consists of the provisions made in an underlying computer network infrastructure, policies adopted by the network administrator to protect the network and the network-accessible resources from unauthorized access, and consistent and continuous monitoring and measurement of its effectiveness or lack combined together. The terms Network Security and Information Security are often used interchangeably. Network Security is generally taken as providing protection at the boundaries of an organization by keeping out intruders hackers. Information Security, however, explicitly focuses on protecting data resources from malware attack or simple mistakes by people within an organization by use of Data Loss Prevention DLP techniques. One of these techniques is to compartmentalize large networks with internal boundaries. Employees have to cross these boundaries and be authenticated when attempting to access protected information.

Network protocols are a set of rules, conventions, and data structures that dictate how devices exchange data across networks. In other words, network protocols can be equated to languages that two devices must understand for seamless communication of information, regardless of their infrastructure and design disparities. To understand the nuances of network protocols , it's imperative to know about the Open Systems Interconnection OSI model first. Considered the primary architectural model for internet working communications, the majority of network protocols used today are structurally based on the OSI model. The OSI model splits the communication process between two network devices into 7 layers.

This tutorial explains types of network protocols and their functions in details. Understanding these basic network protocols with functions will help you in managing network effectively. Learn how the most common types of network protocols works in computer network. The main difference between the two protocols is that TCP uses a connection-oriented transport, while UDP uses a connectionless type of communication. When the TCP protocol is used, a special connection is opened up between two network devices, and the channel remains open to transmit data until it is closed. On the other hand, a UDP transmission does not make a proper connection and merely broadcasts its data to the specified network address without any verification of receipt.

Types of Networking Protocols

Both of these protocols are involved in the process of transmission of data. While UDP is used in situations where the volume of data is large and security of data is not of much significance, TCP is used in those situations where security of data is one of the main issues. While the transfer of data, the existence of ports is a matter of high significance. Each data packet comes with a port number associated with it. This enables the protocols to decide that what are the requirements of the data packets and to which port are they supposed to be directed.

Similarly many of the official assignments refer to protocols that were never or are no longer in common use. This article lists port numbers and their associated protocols that have experienced significant uptake. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports. They are assigned by IANA for specific service upon application by a requesting entity.

For example, port 80 is used by web servers. Port to These are ports that an organization, such as application developers, can register with IAMA to be used for a particular service. These should be treated as semi-reserved. Port to These are port numbers used by client programs, such as a web browser.

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.

In computing, a protocol is a convention or standard that controls or enables the connection, communication, and data transfer between computing endpoints. In its simplest form, a protocol can be defined as the rules governing the syntax, semantics, and synchronization of communication. Protocols may be implemented by hardware, software, or a combination of the two. At the lowest level, a protocol defines the behavior of a hardware connection. While protocols can vary greatly in purpose and sophistication, most specify one or more of the following properties:. The Internet Protocol Suite, like many protocol suites, may be viewed as a set of layers.

Frequently Asked Questions. What are ports and protocols? Tags: port , protocol. As per its word definition, a protocol is a set of rules. In computer networking, a protocol defines a standard way for computers to exchange information.

Below, we take a look at these protocols, provides a basic description of their function, and lists the port numbers that they are commonly associated with.
