What are they, what are they for and what are the main network services?

If you have begun to study about Internet security, you may find protocols or network services, which are nothing more than the foundations for communication within the system.

The connections made through a network platform are made up of a series of barriers and parameters that allow telecommunication to be established .

This is similar to different daily aspects of the human being, because whether it is to watch television, communicate on the cell phone or make a purchase in the supermarket, a series of steps must be carried out correctly to achieve this objective.

Network protocols work in the same way , as each information transmitted by the computer complies with the rules established by the connection.

Even, it does not deal only with the data, since they are also responsible for granting an identification, address and meaning to the computer that connects to the Internet .

So, keep reading this article to understand how these parameters are set and function within a network system.

What is the purpose of network services?

In relation to the aforementioned, it is known that a network protocol is one that establishes a set of rules to control communication between computers and devices that are connected to the Internet.

The purpose or objective of these limitations is so that each computer has the opportunity to obtain an identification that allows it to navigate the networks .

Likewise, it is in charge of controlling the fluidity in which the information is transmitted, in the form of “feedback”, so that it can verify the reliability of the data.

How is communication established between the protocols of a network?

An easier way to understand how network services work is by using the following example:

Large corporations like Google establish a connection network that will work to communicate to all the teams that are within their architecture.

An administrator is the one who will be in charge of creating the protocol, which will allow the connection to each other, either through wired or wireless means.

In other words, the protocols are classified and work based on the size they must occupy (whether wide or local), and the type of firewall and identification that they will grant to each computer.

4 most used network services today

Since the multiple occupations covered by Internet network protocols have become clear, it is necessary to mention only those that are common.

IP – Internet Protocol

His name is widely recognized by all Internet users, as he is the one in charge of establishing the set of rules for the transmission of information through the network.

It is also considered as a series of specifications for the connection, since it establishes the IP address with which the computer will work and the path through which the data exchanged over the Internet will travel.

DNS – Domain Name System

As its name indicates, it is the parameter that is responsible for translating domain names to IP addresses , so that the user can access the page.

At the same time, the DNS serves the purpose of making it easier for people to navigate through the Internet, since it is clearly easier to remember a name like Wikipedia , rather than a series of numbers that make up your server address.

FTP – File Transfer Protocol

It is the easiest method to transfer files across computers using the Internet.

This type of network services uses TCP and IP , which are nothing more than transmission and address control. In this way, they manage the transfer of data to locate them within the traffic, and thus later reach their destination.

DHCP – Dynamic Host Configuration Protocol

Considered the most important of all services, since it is the one that establishes the connection between client and server to obtain dynamic management.
