Remote Computer Connection & Login Protocols: Telnet vs FTP vs HTTP
The question “__________ allows you to connect and login to a remote computer” is best answered by (i) Telnet, because Telnet is an interactive, text-based protocol designed for establishing a remote terminal session (connect and log in).
By contrast:
- FTP focuses on file transfer (with login used to authenticate for access), not interactive remote terminal sessions.
- HTTP is used to request and retrieve web resources; it may support login for web applications, but the protocol itself is not the classic “connect and log in to a remote computer” terminal protocol.
A helpful mental model is: Telnet = remote terminal session; FTP = file transfer; HTTP = web request/response.
type="tip" title="Pro Tip" content="In exam-style questions, phrases like “connect and login to a remote computer” usually point to Telnet because it was created for terminal login sessions."
