Accessing Raspberry Pi through SSH

SSH stands for Secure Shell. It is a secure channel created over an insecure network. The channel consists of a server and a client. This channel uses public key cryptography and can be used for secure transmission of passwords, remote log in, command execution etc.. SSH can be used when we cannot physically access the Raspberry Pi due to various reasons like the USB ports are engaged or the board is in a remote location. This method also minimizes hassle [...]
