Explanation

SNMP (Simple Network Management Protocol) uses 'community strings' as a form of authentication. The string 'public' is the well-known default read-only community string in SNMPv1 and SNMPv2c, allowing read access to device information such as interface listings, traffic counters, and system details. Telnet provides command-line access using a username/password, not community strings. SSH also uses credentials, not community strings. RADIUS is an authentication, authorization, and accounting (AAA) protocol and does not use community strings.
