what is ssh used for

SSH stands for Secure Shell, which is a network communication protocol that enables two computers to communicate and share data securely. It is widely used by network administrators to manage systems and applications remotely, enabling them to log in to another computer over a network, execute commands, and move files from one computer to another. SSH provides strong encryption and integrity protection, making it a secure alternative to non-protected login protocols such as telnet and insecure file transfer methods such as FTP. It is also used for interactive and automated file transfers, issuing remote commands, and managing network infrastructure and other mission-critical system components
