Which service allows remote login over internet?

Appeared in: UP NHM CHO 7 Sept 2022 (Shift-2)

Explanation

Telnet is an application-layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection.
Its primary purpose is to allow a user on one computer to log into another computer that is on the same network or on the internet.
The user can then enter commands on the remote computer as if they were sitting in front of it.

Option B: File transfer, typically using File Transfer Protocol (FTP), is designed for the bulk transfer of computer files between a client and server on a computer network. It does not provide an interactive command-line session for remote control.
Option C: The World Wide Web is an information space where documents and other web resources are identified by URLs, interlinked by hypertext links, and can be accessed via the Internet. It is used for browsing websites, not for remote system administration.
Option D: Usenet is a worldwide distributed discussion system. It consists of a set of 'newsgroups' with names that are classified hierarchically by subject. It functions like a bulletin board system and is not used for remote login.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Internet Protocols and Remote Access as background academic context rather than a clinical decision trigger.
Understanding basic network protocols is part of the digital literacy required for nurses using Electronic Health Records (EHRs) and other hospital information systems.
While Telnet itself is an outdated and insecure protocol, the concept of remote access is highly relevant. Nurses may use secure remote access (like VPNs or SSH) to connect to hospital networks for various tasks.
What if the question asked for a secure remote login service? The answer would be SSH (Secure Shell), which has replaced Telnet in most applications because it encrypts the entire session, protecting sensitive data like passwords and patient information (as mentioned in SRC_2283 regarding data security).

How to Approach the Question

First, identify the key phrase in the question: 'remote login'.
This asks for a service specifically designed to let a user control another computer from a distance.
Next, evaluate each option based on this primary function.
File transfer is for moving files, not logging in.
World Wide Web is for browsing websites.
Usenet is for online discussion forums.
