{{Unreferenced|date=June 2023}}{{About|the term standardized by Open system||virtual console|and|virtual terminal (payment processing)}}

In [[Open system (computing)|open systems]], a '''virtual terminal''' ('''VT''') is an [[application service]] that:

# Allows [[Server (computing)|host]] terminals on a multi-[[User (computing)|user]] [[computer network|network]] to interact with other hosts regardless of [[computer terminal|terminal]] type and characteristics,
# Allows remote log-on by local area network managers for the purpose of management,
# Allows users to access [[information]] from another host [[central processing unit|processor]] for transaction processing,
# Serves as a backup facility.

[[PuTTY]] is an example of a virtual terminal.

[[ITU-T]] defines a virtual terminal protocol based on the [[Open Systems Interconnection|OSI]] [[application layer]] protocols. However, the virtual terminal protocol is not widely used on the Internet.
