Network protocol are standards that enable two or more points in a network to share and transmit information. This set of rules can be defined from well-defined rules, syntax, a synchronize communication between the network members, and connection recovery methods for possible errors that it may have.

A network protocol can make up of several layers. Thus, a task assigned to the network can be divided into smaller and simpler tasks, and then each function (layer) of the protocol cooperates to carry out the main task. The expression “protocol set” refers to the group of protocols collaborating to carry out the job. One of these sets is the TPC/IP .
One of the schemes on which network protocols are based is the Open Systems Interaction Model or OSI (for its acronym in English), created in 1983 by the International Organization for Standardization. This model consists of 7 layers :
On the other hand, the Transmission Control Protocol or TPC (for its acronym in English) is also a schematic model of a network protocol, which is also widely implement. The main difference with the OSI model is that it consists of only 4 application layers:
The application of network protocols depends on the devices that make it up and also the problems they intend to solve. A vast majority of these are cited below:
Allows communication between network members. The best-known communication protocols use both analogue and digital signals and are implement for both file transfer and internet access.
It ensures that the information passing through the network can only be manipulate by its users; besides, only they have access to the network. These are some of the most used:
It is concerned that the network works optimally through procedures that involve switches, routers and also servers. These are implement in all networks, of which we can mention:
In addition to the Bluetooth, Router, Encryption and IP protocol, there are other protocols that are use on a daily basis:
Without network protocols, LAN, WAN connections , and the Internet itself could not be a reality. These use several protocols cited in this article to provide a smooth, stable, and also secure network experience. They can also implemented in device connectivity via Bluetooth and Wi-Fi connections: since the router has its protocol and uses others for an integrated experience.
Network protocols are rules, contracts, and data structures that dictate how devices exchange data across networks. In other words, network protocols can be link-to languages that two devices must understand for seamless data communication, regardless of their infrastructure and design disparities.
