Question

Which of the following commands can be used to copy files across systems?

1) ssh
2) telnet
3) rsh
4) None of the above

Answer 1

The correct command to copy files across systems is s`sh.

The answer is option ⇒1) s`sh

Step-by-step explanation:

SSH, or Secure Shell, is a network protocol that provides a secure way to access remote systems and transfer files between them. It uses encryption to protect the data being transmitted, ensuring the confidentiality and integrity of the files.

Telnet and RSH are not recommended for file copying as they do not provide the same level of security as SSH. Telnet transmits data in plain text, making it vulnerable to eavesdropping, while RSH does not use encryption and is susceptible to various security risks.

The answer is option ⇒1) s`sh
