HOW SSH PROTOCOL WORKS

What is SSH?

SSH stands for secure shell. It is a networking protocol which is used to secure the data flowing between the SSH client and the servers over a public network such as the Internet.

WORKING:-

When a client tries to connect to its SSH server its needs to be verified. To establish a secure connection between them. In this protocol, this verification is completed using the exchange of cryptographic keys. And after when the client and the server are successfully connected, the process of transmission of data takes place. But the data in an encrypted form. So as a result, a secure tunnel like security system is formed. In general, the port 22 is used for this SSH connection.

USES:-

SSH is famous among the network administrators. Because it helps them to manage their systems and applications remotely, allows them to log in to another system or computers over a public network, execute commands and move files from one device to another.

How to use a 16x2 lcd display with Arduino

So today I will tell you how to use the 16x2 LCD display on the Arduino projects. If you are doing any kind of projects then you should interact with the user in the simplest process.To add any kind of output device is the key to simplify that project. you may show the options or the compilation details using that. There various types of displays available in the market but among them the 16x2 LCD display is the famous and cheapest one.As it has a very simple process to implement them in the projects. pinout for the 16x2 LCD display: circuit diagram for 16x2 LCD display: Test code to check the connection is properly done or not: /* LiquidCrystal Library - Test code #DNY Demonstrates the use a 16x2 LCD display. The LiquidCrystal library works with all LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them ...

HOW WIFI WORKS?

WHAT IS WIFI:- It may happen that now you are connected to a wifi router and surfing the internet through that.But did you know how the data is displaying in your computer or phone's display? when your device is not connected with any of physical connecting wire. The wifi is basically an electromagnetic radiation, just like the microwave, visible light or the gamma rays but the only difference is the use, the frequency and wives length of that radiation. Wifi signals basically use the two bands 2.4 or 5 GHz. And it basically transmits the data in the form of 0 and 1. The wifi signal uses the same concept of a radio F.M but this communication is two way. HOW IT REALLY WORKS:- The wifi networks basically break the data in small encrypted packets and send back and forward between your router and portable device. The packets also have the address of the destination node and the decryption key. And after the data is received by your device t...

What is SAMBA (software) Server ?

So, what is samba? is today's topic, I think you already know about the term server. Now the Samba is a free software for that server management, it is based on SMB(server message block)/CISF networking protocol and originally developed by Andrew Tridgell.It is useful to provide printer and file services for various Microsoft Windows client machines. SAMBA runs in most of the OS presents in the market like Windows XP to Windows 10, Mac OS servers, Unix, Open VMS, Linux and Solaris etc. Samba is released under the terms of GNU General public license. General information The software is written in c, c++, python. Operating system: Multiplatform. Type: networking file system. Official website: https://www.samba.org/ *in future I will use this concept to make a personal server. so for the future updates, please stay connected and also subscribe my youtube channel: https://www.youtube.com/c/dnytechnicals
